Factors that hinder market circulation of vacant houses are assessed comprehensively. Effective measures corresponding to these factors are then verified in this study with stated preference (SP) survey based on a questionnaire for vacant house owners. Principal analyses have revealed that 1) it is difficult to put vacant houses into market circulation using conventional measures when the vacant houses are considered by the owners as necessary for use as a storehouse or as not problematic; 2) the effects of measures against vacant houses implemented by each municipality such as subsidization for reform activities are limited; whereas 3) the increase of fixed asset taxes as one new measure against vacant houses elicited strongly beneficial effects for general factors including factor 1) described above, which is difficult to solve.

The purpose of this study is to clarify the economic possibility of using old detached houses as company dormitories. As the measure, we calculated amount of profit and cost when companies used old detached houses as company dormitories. As a result of analysis, there are only two housing stocks which profit is higher than cost without subsidies. If Takasago city subsidizes 75% of tax revenue from settlers to companies, the number of these housing stocks will increase to 1,659. On the other hand, the number of rented house residence households living in neighboring cities is 1,258 and they are thought to be more likely to move into the company dormitories. From the above results, there is the economic possibility that old detached houses are used as company dormitories in terms of the number of housing stocks.

Because of the increasing number of vacant units and the shortage of hotel rooms, it is assumed condominium vacant units will be converted to accommodations. There are three issues to use vacant condominium units as accommodations in Japan, the first is the control of unit management as a whole, the second is the relation between the ownership and management and the third is consumer protection. Hawaii has made the time share low in 1980 to protect customers. The time share developer has to resist the development both with disclosure statement and plan manager. The plan manager manages the whole time share units according to the unifying policy. The registered condominium hotel operator also manages the whole condominium according to the unifying policy.

The National Urban Greenery Fair (NUGF) is a national event held by local governments to creating communities and urban environment with flower and green. This paper aims to clarify the effects and to discuss how to identify the performance as the Legacy, through case studies on the nine cities which had held the NUGF. The major effects of the NUGF are new activities and organizations for park management based on the main site and administrative organization system and new project by the park and green space department. Some cities recognize their effect on city branding and tourism promotion. Furthermore, the linkage between the policies and executive committee of the NUGF is important to develop the effects as a legacy. Although the committee members who know before and after the event recognize social effects such as raising awareness and creating a cooperative social system through the preparation of the event, we could not find appropriate evaluation system. Such evaluations and economic effects from the viewpoints of business should be clarified for diverse actors to understand that the NUGF could be an opportunity as a social implementation to find the possibilities of park and green spaces.

In 1967, Agricultural-housing was launched as a city development concept to combine agriculture and community housing. This research considers agricultural housing from its history and conception in its early stages (1968-1979) and compares three financial systems about agricultural housing. These were 358 cases (736buildings,10303 units) built as the product of the agricultural housing finance law. Almost all of the agricultural housing is concentrated in several prefectures using the finance system. And the number of applicants was 95.3% for individuals, and 69.3% for one building. Because the system was designated for building costs.The pure Agricultural-housing concept include land use plans. Moreover this supply situation just partly reflects the pure Agricultural-housing concept in its early stages.

The land reclamation of built sites has been implemented in the suburbs of many cities in China for the past 20 years, which should be suggestive for shrinking cities in Japan. This research aims to clarify the background, policies and method for implementation of land reclamation system in rural areas of Shanghai City, and to clarify its effects and issues through the case study of Songjiang District in Shanghai. Consequently, it points out the effect in improving the quality of built environment and the productivity of the town, and the issues in community building and management after the conversion of residential facilities.

This study examines the roles and activities of Local Committees, which are legally defined neighborhood organizations involved in the formulation process of the local plan in the city of Copenhagen. Our investigation revealed that Local Committee members are selected from citizens’ organizations in a variety of specialized fields that are active in the neighborhood, which ensures that the system is fair and objective. Moreover, in the formulation of the local plan, the Local Committee holds civic meetings, and prepares and submits documents that summarize the opinion of the residents. This is accomplished through discussions at the specialized branch organizations, with final decision made by the Local Committee. Based on our examination, we found that the Local Committee plays an important role by acting as a representative of public involvement in the local plan formulation process.

This study aims to determine the relationship among the public participation (PP) consciousness about compact city polices, the effect on PP and activity characteristics of neighborhood associations in Portland City. By using principal component analysis, four axes were drawn: 1. Activation degree of Local activities, 2. Degree of Urban density and CN, 3. Activation degree of Attending compact city polices, 4. Pursuing tendency of Social welfare activities. As a result of typology, it was possible to classify five groups. The affinities among people density and composition, the method for PP, and etc. are determined through comparative analysis of each group.

The importance of promoting sustainable community-based Machi-zukuri is now widely recognized. In this context, recently, many supportive measures such as community organization, community rule, financial support, community project are established in many areas. This paper aims to discuss present situations and to analyze limitations and future directions of enabling platform through the case of Nagoya City. Nagoya City firstly established the supportive measures under the Urban Master Plan in 2012 and following social movement of community design and public space management, the City decided to upgrade these measures as an enabling platform in 2017. Through the reviewing the institution and practical implementation of Nagoya’s case, it was found out that the platform was intended to promote Machi-zukuri through step-by-step support and well managed, but there are some tasks for further promotion.

This study aims to clarify the transition of land ownerships in the central commercial area in Kuroishi City after the modern era, and thereby obtain basic findings for reuse of vacant lots in local town. As methodology, old cadasters and public figures were employed to trace the changes of ownerships and lot forms of 47 lots between 1890-1953. As a result of the analysis, three features were identified: First, the open space behind the main building (kaguji) flexibly accommodated the changes in the lot size according to the commercial status. Second, in spite of the changes of ownerships and lot forms, spatial configuration derived from traditional life style in snowy region was sustained. Third, there was unique land management strategy where a land is temporarily made commons by several households including leading merchant family, and it’s inherited to the present day.

This paper characterized ownership of arable land in one of the Jori-grided villages, Harie, as a part of an important cultural waterfront landscape. Given regional tradition in dispersed arable land ownership plugging each farmer into multiple waterways for multi-generational maintenance, this paper examined arable land ownership through inter communal relationships in transition of modernization in the mid 1980’s. With referral to former studies on her development of the village in the Medieval Period, quantitative analysis led conclusions as followings: A) Those who lives outside of the village that formerly shared the regional dam are included as landholders in Harie. B) The older developed area has been equally shared by landholders with her water utilization. C) There is certain engagement in landholders in specific village section with her water utilization.

Historic streets are precious historic properties in common with a historic building. Historic streets and many buildings remain in Furu-machi Kagai, Niigata City. To date, no study has clarified the history regarding formation of Shinmichi and alley. This study attempts accurately to clarify the unknown history regarding these streets focusing on early Edo period on middle Showa periods based on old maps and literature review. Major results are as fillows. (1) Regarding formation of Shinmichi, 8 bancho side of Higashi-shinmichi was formed late Edo period, other shinmichi were formed middle to late Meiji period. (2) Regarding formation of alleys, Rokken-koji and Shonenji-koji are historic alleys. Rokken-koji were formed early to late Edo period, Shonenji-koji was formed late Meiji period.

At present, urban farmland is being evaluated for its many functions. However, urban farmland is decreasing year by year, despite that further residential land development is not desirable. Therefore, in this research, we assumed that the development right of urban farmland is transferred to the central area by the method of development right transfer. First, the transfer rate of the development right was determined by the land value ratio and the land residual method. And we applied that rate to the business model. Furthermore, we verified the profitability of the business side developing in central Tokyo when the development right is transferred. Two things became clear by this research. The first is the relationship between the scale of development in central Tokyo and the development right that can be transferred, and the second is how the business side operates the development right transfer to earn a profit.

In the rooftop garden of urban complex redevelopment, Futako Tamagawa Rise, 4 types of zones (observatory deck, lawn field, biotope pond, garden deck) were set as the experimental sites, and the physiological and psychological effects to 27 university students by the nighttime activities in each zone were observed. By monitoring saliva amylase activities, the nature observation in biotope and the rest on lawn field had larger effects in physiological stress mitigation. By the Profile of Mood State 2 (POMS2®) test and the Semantic Differential (SD) method of impression questionnaire, these zones had meaningful effects in reducing psychological stress such as strain and tiredness compared to the observatory deck. These physiological and psychological effects in the night-time use of each zone are to be effectively utilized and combined in the spatial layout and composition of the rooftop greening in the urban redevelopment.

In this research, the social experiments by using wood panels (150cmX140cmX9cn) as the wood-touch tools that increase the people’s intents to use the riverside public space were implemented. The questionnaire surveys in these social experiments reveals that 1) wood panels can enhance the positive image of the riverside public space, 2) evaluation of the wood-touch use of the wood panels is better than the wood-terrace use, 3) even though the use of the wood-touch use, the evaluation of the wood panels are strongly influenced by the extent how people are satisfied with the activities, and 4) wood panels can make people use the riverside public space in not only the events but also the ordinary days.

This study was aimed to discuss the guideline for greening of city in the next era by grasping the character of them in central part of Tokyo. We made an analysis along the past study on 13 wards of Tokyo, which has original guideline. And we could know that each ward devise their guideline for greening along their original problem. The first devise is the relation with architectural planning of projects in the city, the second devise is the consideration of various functions of greenery which are required n central part of Tokyo, and the third devise is the consideration of greenery foundations to healthy growth of plants. In future we are able to develop these devises for our city in next era’s guideline.

This paper deals with Haneda Athletic Ground that Keihin Electric Railway and Japanese Excercise Association opened in the late Meiji period. It aims at the determination of its social position to analyze the basic establishment Maintenance and Operation Contents of the Haneda Athletic Ground. Most of the athletic grounds were located in schools, and there were few open and general athletic grounds at that time. But Haneda Athletic Ground was opened not only to some elite students but also to the general public such as workers. Haneda Athletic Ground provided opportunities for watching sports competitions and holding corporate athletic events by using means such as the construction of several stands.

A social experiment for the revitalization of the public space is an important issue today. This study focus on the activity caused by the social experiments area setting the street furniture in western sidewalk of north building of Grand Front Osaka. This study first verifies the yearly change as well as effect caused by events of activity. Second, I analyze the type division of each activity and change of atmosphere of space chasing that user in the public space. As a result, this study makes clear the difference between every season and weekday / holiday and clarify the appearance of repeaters and the around effect of the activity.

The purpose of this study is to clarify the significance of historic preservation and utilization for Japanese American community in the old Japan town in Seattle. The area where ethnic communities live is attractive as a tourist destination. However, in Japan, the attractiveness of such a district is utilized only in a limited area. Historic preservation and utilization are popular in the target area, and we investigated the actual condition from before World War II to the present. We focused on the Japanese American community's own organization, education, culture, architecture and landscape, in addition to social background and administrative measures. As a result, it was found that the preservation and utilization of built environment to help understand the life history of ethnic communities is useful for maintaining the ethnicity of the district.

The existence of “Yama-ate” has also been confirmed in grid urban areas in parts of Hokkaido. Among these are cities forming a landscape axis toward “exotic rocks” that are far closer to urban areas. In this study, we use GIS to objectively measure axis lines to these exotic rocks, and clarify the formation process of these axis lines. Then, we verified the historical landscape positioning of current urban design. Based on the results of this analysis, we confirmed that the formation process includes cases where a specific road was planned toward the exotic rocks. This was set as the main route. This has been recognized as a geographical symbol since the Meiji era, when the urban areas were formed. For this reason, we have clarified the actual situation in which their establishment in exotic rock areas and along roads progresses.

This paper aims to clarify the current states and issues of reconstructions of private houses in Newar historical settlements in Kathmandu Valley through a reconstruction case study in Khokana, a world heritage tentative list site of Nepal, where the international cooperation project for the protection of cultural heritage after Nepal earthquake has been carried on since November 2015. The study illustrates the transition of affected traditional house reconstruction in Khokana in chapter 2, reviews the reconstructed private houses with RC after the earthquake in order to understand people’s needs and trend in chapter 3, and reviews the new policy, “Basic construction guideline related to settlement development, urban planning and building construction” including a heritage settlement in chapter 4. It clarifies the gaps in between this new policy and reality based on the case study in Khokana in order to proceed to Newar historical settlement conservation in Kathmandu Valley on the right track.

The number of foreign tourists visiting Japan has been on a rapid increase, especially since the 2000s, supported by the government's tourism promotion policy.In such a context, this study aims to clarify the location trend of hotel that were built in recent years. As a result, the following three types were obtained as main location patterns.1) Small office buildings near train stations have been converted into mid-range, accommodation-specific hotels. 2) Small offices away from train stations were demolished, and were rebuilt into low-range, accommodation-specific hotels. 3) In a commercial area close to terminal stations, several offices were demolished to construct a large-scale complex buildings, and high-class hotels were established in the part of the buildings.

This study defines the area where 40 or more houses had been built consecutively in the 1970's as "Housing-Increased Area". This study aims to clarify the ideal living environment of the residential area where inhabitants are aging and neighboring shops and public transportation might have withdrawn by focusing on inhabitant's condition and its change. For the purpose, we select 6 cities and clarify the following points. i) By hearing to the municipality: There are some types of the Housing-Increased Area. ii) By field survey: There are cases that the vertical gap between public transportation and the area makes low convenience. iii) By questionnaire survey: There are few residents who use the food retail store by public transportation.

In recent years, children's behaviors tend to be regulated by parents who worry about crime and accidents. It has been pointed out that this has an adverse effect on children’s development, reducing the opportunity for children to act freely without adult accompaniment. The purpose of this study is to clarify the relationship between restriction on children’s outdoor activities and regional factors. First of all, in order to clarify the tendency of restriction in an exploratory way, interview survey was conducted on 16 parents with primary school children. Next, based on the results of the interview survey, a web questionnaire survey was conducted women with primary school children living in Kanagawa Prefecture. As a result of covariance structure analysis (n = 440), it was found that in areas with low urbanity and few children, there are few people watching over children, and parents become more anxious, so regulations become stronger. In addition, it was also revealed that children of highly socially cohesive parents were less restricted.

District plans that control FAR by uses and urban form were widely designated in Chiyoda Ward, Tokyo from the latter half of the 1990s to 2010s in order to recover residential population and to achieve disaster mitigation and efficient use of land by promoting the reconstruction of individual buildings. This paper aims to analyze the effectiveness of one of the district plans in Kanda area from the viewpoints of (1) spatial transformation, (2) reconstruction of individual buildings and (3) social change. The paper quantitively and qualitatively grasped the transformation of the urban area with increasing construction of multi-family housing and increasing mix of uses from the dominant office use after the designation of the district plan.

The purpose of this study is to evaluate the population declining local government by questionnaire survey by the comparison before and after of moving in and text mining through the use of open question in case study of Minamiboso City, Chiba Prefecture. In the result, the main reason of moving in is due to work and family. For before and after of moving in, incoming residents by own intention is satisfied with the locality of Manamiboso City. On the other hand, incoming residents by not own intention is dissatisfied with life convenience. As a result of having classified residents by difference in satisfaction and dissatisfaction, residents satisfied with the locality expect transference promotion to the city by the utilization of vacant houses, etc. High dissatisfaction residents find the improvement of life convenience facilities and administrative services.

The study aims to clarify the possibility and issues by focusing on the case of using the “City Convenience Improvement Agreement” as a public space management method by the public-private partnership. As a result of the study, this agreement has possibilities of becoming a profitable business and flexible use. On the other hand, The first issue is continuity of public space management. The second issue is the gap to awareness of “Public”, which causes the disagreement between public administration and the private sector.

The purpose of this research is to grasp the actual condition of the project related to development of physical infrastructure in Crowdfunding. As a conclusion of this research, it became clear that there are two types of characteristic project forms; one is a profit-making project providing service and the other is a public benefit project. The former tends to be handled by commercial organizations and can be relatively easily achieved. Although it is basically carried out on privately owned land, much of them has public profitable free space. The latter tends to be handled by non-profit organizations and can not be relatively easily achieved. This type of project receives subsidies from local governments and tends to use Crowdfunding to make up for insufficient business funds.

The main purpose of this study is to clarify conditions of designated dwelling attraction areas by using discriminant analysis from the view of living environment indices. Firstly, we analyzed cities that are designated location normalization plan in terms of population density and reduction rate of urbanization promotion area toward dwelling attraction area. Then, we classified the cities into 6 types by cluster analysis. Then, we focused on Tsuchiura City, Tsuruoka City, Minoh City, and Kumamoto City based on the types. Then, we developed discriminant models to identify dwelling attraction area by employing living environment indices. Finally, we applied the discriminant models to the other type cites. As a result, the discriminant model explain differences between low reduction rate city and high reduction rate city.

To examine the effect of undergrounding and utility pole removal projects on land prices considering the heterogeneity of spatial and price ranges, this study estimates the land price functions using three econometric models by collecting and sorting past data on undergrounding projects in cooperation with Kyoto City. The marginal effect of undergrounding projects and the associated characteristics are clarified in terms of both spatial ranges and price ranges at each quantile of land price. In particular, the marginal effect of these projects tends to be attenuated by spatial distance. Within a distance of 0-50 m from an undergrounding and utility pole removal project, the effect is more pronounced in higher land price ranges than in lower ones. Additionally, the marginal effect is 38.7 points higher where existing utility poles are removed compared to where only the underground work is completed.

This study aims to suggest the ideal urban structure for easy access to local services by walking or using public transportation. We classify Urbanization Promotion Area in Matsumoto city as to urbanization stage and examine the accessibility to eight kinds of local service with two steps, walking and using public transportation. As a result, we clarify the following. (1) 1970 DID is accessible area to the local services and public transportation stops. (2) Public transportation in local city has two effects, one is the improvement of accessibility in 2015 DID outside 1990 DID and detached Urbanization Promotion Area, and the other is the increase of available services within a certain time especially in the 1970 DID.

Japan has been supporting establishment of the legal system of Land Readjustment in developing countries since 1980’s. Land Readjustment is known as an urban development method which has characteristics of land re-plotting and self-financing. In recent years, Urban Renewal and Condominium Reconstruction which have similar characteristics to Land Readjustment are also expected to solve urban issues in other countries which suffer from rapid urbanization. Mongolian government started the examination to apply Property Right Exchange Development including those three methods in 2007. Through the technical assistance of Japan, Urban Redevelopment Law in Mongolia was approved in 2015. This study clarifies characteristics of legal system of Property Right Exchange Development in Mongolia. Then this paper discusses the related issues to be considered for the establishment of the legal system of Property Right Exchange Development method in developing countries based on the study of the characteristics of Property Right Exchange Development method in Mongolia.

Recently in Japan, the developments of a smart community consisting of hundreds of detached houses have been observed. However, its quantitative performance has not been understood yet. The aim of this study is to clarify the district planning issues related to the energy performance by simulation of the community’s energy demand and PV generation amount. As a result of estimating under various conditions in the virtual smart community, the following things have become clear: 1. It is possible to build a zero-energy community by applying a 5.0 kW PV in each house and unifying the orientation of the houses to the south. 2. Even if the house specification is the same, the energy performance would be changed by the attributes and the number of the residents. 3. In order to save energy in the city, it is effective to attract large number of households to the smart community.

Recently, under the prevention of global warming, the low carbon development, such as net Zero Energy House (ZEH) is required because of significant reduction of CO2.ZEH can supply energy under at the urban disaster, such as blackout, because it normally has renewable energy systems. However, the house with surplus power generation, there is a limit to sell excess electricity because of the electric power system limitation. Therefore, although there is a demand for electric power interchanging of surplus power on a block basis, the specific way is not clear. This paper deal with clarify the ideal way of ZEH block development for sustainable city construction in Ota-ward, from the viewpoint of environmental and disaster prevention. As a result, it is cleared that development of the ZEH block is useful to the drastic reduction of CO2 and the keeping daily life at the time of disaster.

Municipalities are aiming to form core areas that consolidate facilities in response to the population decline, but withdrawal of facilities is expected and cooperation between core areas beyond municipal areas is required. However, hierarchy of core areas has not clarified. This article was conducted to contribute to the setting of core areas considering wider areas by clarifying the gap of the actual setting of the core area and the facility location from the wide area perspective for the future cooperation between the municipalities. Analysis results revealed that 1) core area set exists in the plan but it is not extracted from the actual situation and 2) a core area exists which has differences between in the plan and in the actual situation. Consequently, a spatial and hierarchical gap has arisen between core area planning and reality. Results indicate the importance of setting up core areas from a broad perspective.

For circumstances of declining population, the Compact City has been regarded as an ideal urban form in Japan. During the five years since the law for location optimization plan was enacted, many municipalities have formulated a plan incorporating Compact City policies. However, some have too many core areas in urban master plan which is the upper-level-plan of location optimization plan, and a gap of core areas between both plans is also shown. We aim to help plan valid core areas by ascertaining changes of urban functions located in core areas and the change of the core areas’ position from an urban master plan to a location optimization plan. Results demonstrate that most businesses decrease the number and ratio of facilities in core areas. Furthermore, facilities are few in core areas that had not been set up as core area in the urban master plans but which were set by a location optimization plan.

This study aims to clarify designation state of inducing areas of residence and urban function, and of original area on Location normalization plan(LNP) by focusing on two-layer relation between LNP and Urban planning. As a result, we revealed that most cities designated inducing areas base on Land use in spite of different designatable area by area division. In designation of Residence inducing area(RIA), there are two trends that designation based on local characteristics; population, public transportation, urban function, and strategic designation based on public transportation wayside. However, in designation of Urban function inducing area(UIA), many cities designated range and number of areas based on sort of Inducing facilities. Moreover, many original areas were designated outside area of RIA inside Land use, and core areas excluded UIA based on Municipal master plan.

The scope of this study is to discuss the new way intensifying central urban base by analyzing the relation between the past strategy of central area revitalization plan and the new policy of urban function induction area. From researching 21 local cities, we clarify the followings: 1) The strategy of central area revitalization plan is divided into four types and the operation policy of urban function induction area is also divided into four types. 2) By crossing the both four types and simplifying the result, five new strategic ways intensifying central urban base are clarified with typical examples. This study discusses their possibility and issues.

This study aims to clarify the policies and backgrounds and discuss the differences of Residential Promotion Areas among cities whose area ratios of Residential Promotion Area to Urbanization Promotion Area are contrasting. We investigated how Residential Promotion Areas were determined by analyzing Location Normalization Plans. Through the analysis, it is found that the area ratio of Residential Promotion Area to Urbanization Promotion Area differ greatly among cities and there are various policies and rules for setting the areas. Cities which set the Residential Promotion Area narrowly were trying to increase population within the area. On the other hand, cities which set the area widely set the range where population will be maintained as a Residential Promotion Area.

Urban core areas that consolidate urban service facilities have long been sought. However, concern has arisen that facilities will be decreasing even at urban core areas because of population decline in local cities. Decreasing facilities are attributable to various factors. Measures for maintaining urban core areas differ. Therefore, to clarify factors that decrease facilities at the urban core areas from the viewpoint of population decline, suburb outflow, and outflow at other urban core areas, this study produced information related to measures for maintaining and review of each urban core area. Analysis results show that 1) the numbers of facilities are being maintained or are increasing in urban core areas where population is increasing and 2) factors related to the decrease of facilities, such as population decline and outflow to other urban core areas differ exist depending on urban core area types.

The semi-industrial district can use various lands, so it is considered that various land use types can be seen. Also, land use may differ depending on the designated reason for the semi-industrial district of each city. So, this paper analyzes the land use of the semi-industrial district from the viewpoint of the designated reason and system utilization for the so South Osaka city planning area. As a result of this study, we found that land use in the semi-industrial district is largely divided by the two designated reasons. 1) In the area where the reason for designation is “previously designated as a semi-industrial area” or “designated according to the situation where various land use is being carried out”, land use of mixed type and residential type is often seen. 2) In the area where the designation reason "allows or promotes specific land use", land use of public, industrial, and commercial type is often seen.

The Land Readjustment Project has been playing a big role on urban development in Suburban Area. The purpose of this study is to clarify the actual condition of land use conversion after the completion of land readjustment projects in suburban area of Tokyo metropolitan area. We analyzed 55 projects which completed between 1955 and 2000 and we compared superblock's land use planned as educational facilities or apartment houses to current land use. As a result, the rate of land use change of superblocks was found to be higher in sites planned as kindergarten than in sites planned as primary/junior high school.

The aim of this study is to consider that regulation of installation of solar panels on the ground that has progressed to the urbanization control area, and involved after farmland diversion. We analyzed site characteristics at the installation site and site where other development occurred, and compared each other. As a result, we revealed that the larger the scale of solar panels, the worse the location condition of population density, inclination of land, forest proportion and distance to urbanization area boundary. When the power generation output exceeds 400kW, those conditions become worse than other development site. Moreover, solar panels that installed after farmland diversion are small scale and there are many locations near the urbanization area, and accessibility to site, convenience of railway and site shape can be considered as location factors. Therefore, it is desirable to add to the target acts of the Environmental Impact Assessment Ordinance for facilities with a power generation output of 400 kW or more, promote the fluidization of farmland by renting land, and promote the installation of solar sharing-type solar power generation.

If the company town was made in suburbs, the huge company town usually changed to huge housing area after the company was closed. In the case of Kengun Area in Kumamoto city, the result was different. In this paper, we revealed the process of how the company town was changed to one of the biggest center areas of the Kumamoto city. We found that follows: (1) The company town was made through lots of modern skills of urban planning. (2) The urban infrastructure facilities of the company town became the base of the new town. For example, in the big empty lot, lots of newcomers came and opened their own shops. (3) The pick of the shopping mall which was changed from company town was around 1978s along the Kengun Shopping Street. (4) The block shape has not been changed since the company was closed.

The aim of this paper for “OKABIRU” is to clarify the influence of this building which was financed first by the housing finance corporation. Through the examination of the construction process and architectural features of “OKABIRU”,it is clarified the starting point of the study on the architectural history of public housing. Moreover, there are various flexible lifestyles in “OKABIRU” such as the modern life according to the plan at that time, and the relationship between stores and dwellings. Communal housings were supplied a lot. Therefore, this study is a useful discovery for maintaining and inheriting them.

There is a view that the integrations of city planning orders and building orders in the territories Occupied or Annexed by Imperial Japan were influenced by Iinuma’s “Regional Planning Theory” and had advantages to be reevaluated. This study examined the influences and the advantages and concluded as follows. Simple integration was against the theory. The authorities of the building permission systems in the integrated orders were the same as independent law of Japan. Zoning system in Taiwan under Japanese rule was managed by the authority of building orders as well as in Japan. The advantages of the integrations which had been pointed out in the existing study were rejected except for the convenience of application.

Agriculture-residence Initiative urged by Teruo Ichiraku from 1967 to 1970 aiming at supplying houses by farmers yielded the result as some national programs. He wrote the purposes and approaches on this initiative in 5 discussions. One of those programs is the Construction plan of Agriculture-residence housing complex by The Ministry of Agriculture and Forestry. Basic initiative of Agriculture-residence housing complex in Kakio area was made under this program by the Kawasaki-City Tama Agricultural Cooperatives with The Study group of Agricultural Cooperatives. Philosophy of this program and the contents of this basic initiative in concrete area reflected the concept of the initiative by Teruo Ichiraku.

In recent years, evaluation criteria for historical heritages have diversified, and negative heritages such as earthquake disaster remains and war sites were preserved for the purpose of memory inheritance. In this research, I examined how the remaining space affects the inheritance mechanism of tragedy memory for the Hansen’s disease facilities. As a result, it was found that not only the remaining space but also the argument concerning the preservation of the space greatly affects the mechanism of memory inheritance. The memory of Hansen’s disease, it was found that the foundation for inheriting the memory has been prepared through various coordination and discussions on preservation of space.

This study, through the case study of the “Central East Tokyo ” project around Kanda Station and Bakurocho Station, investigates the process to regenerate the existing urban area by small projects such as renovation and conversion of buildings, and utilization of open space, and presents achievements and issues when external social enterprises enter the urban regeneration field as business. By changing the platform of collaboration and the target area flexibly, social enterprises can contribute to urban regeneration over the existing administrative districts, and as a result, district organizations can manage the area proactively. This research points out that it is necessary to have a means and method that monitor the progress of the project and grasp the stage appropriately.

This study aims to elucidate what can be a source of civic pride and how built environment as a source of civic pride influences civic pride factors. Our methods and major findings are: (1) Investigation of the international literature reveals that built environment, culture and sport are regarded as typical sources of civic pride, while nature is not; (2) Questionnaire survey of Toyama shows that the people in Toyama City are most proud of the local nature and food; (3) A factor analysis of the questionnaire survey data shows “Built environment”, “food and nature”, “culture and industry”, and “transit” are the factors of source of civic pride in Toyama. A covariance structure analysis reveals that “Built environment” and “culture and industry” raise identity and attachment and “food and nature” raises attachment and desire for maintaining and reduces engagement.
