This study focuses on conditions and planning negotiation systems of landscape ordinance in Tokyo 23 wards. And we show problems of the landscape ordinances to make use of future landscape polices. In conclusion, we found that there are many measures not to be implemented, such as landscape agreements and Landscape controlled areas.Also planning negotiation systems play a key role in landscape ordinances,and they are operated in all wards.This paper makes clear that planning negotiation systems are different from each ordinance, but all systems have two steps of negotiations and these careful negotiations bring about some results of landscape consideration to buildings

The purpose of this paper is to search for the factor of the various problems between apartment buildings developer and resident around apartment buildings. There were problems respectively for the developer side, for the resident side, and for the system regulations and the system operation. We examined the problem in the system regulated and the system operation.Consequently, there was incompleteness in the above-mentioned points of the method of specifying zone restrictions, the system regulated and the system operation of the deregulation type, the entrepreneur escapes intentionally from Building Standard Law and the development ordinance.In addition, penal regulations of the guidance outline etc. are lack, and regulations of the conflict prevention ordinance are insufficient.

This paper aims bringing out factors of shopping districts by checking websites contents and the number of hits.We checked 67 websites of shopping districts in Yokohama and shopping quarter statistics,and we analysed the factors by multiple linear regression analysis.As a result,most websites have shop information and map information of shopping districts and event information.However cellular phone websites and internet shops are not created.In order to generate more traffic of websites of shopping districts, we showed network service is required.

A purpose of this study is to make indications of public open space utilization and apply the indication to cases in Yokohama suburban residential areas.This study classifies utilization in three functions and use seven indexes.We grasped "the public openness function" based on a ratio of an entrance of public open space.As a result,most public open space opened out more than 40%.We grasped "the walking function" from two indexes of "a ratio of an area of the sidewalk" and "degree of shortening of distance". and we showed most public open spaces had 3% to 4% of areas of the sidewalk.We grasped "the stay function" from three utilaization forms of a (1) rest (2) play (3)stroll. We showed the bench, which we use as a rest,is a popular items,on the other hand,the playground equipment which related to play was limited,The rate of most vacant land area,which we ues as a stroll is a range from 10% to 14%.

The authors had conducted field surveys in Chi-Chi Township since the 1999 Chi-Chi Earthquake to understand the post-disaster recovery process. This paper presents recovery curves for buildings in the area after the Earthquake. The recovery curves in terms of building type (temporary housings, public facilities, rebuilt buildings, and new buildings) were constructed using the building certification data of Nanto County. It was also clarified the differences of recovery process among them. The proposed methodology to construct recovery curves in damaged area will be essential for research into post-disaster recovery because it enables comparative studies related urban planning among different types of post-disaster recovery processes throughout the world.

For the last decade, improvement of an urban ecosystem has become a big issue for metropolitan cites in the world. Because there are few open space in these cities, it is difficult to create a new large habitat for organisms. In this paper, we analyzed the distribution of open spaces covered with vegetation on three different scales in Amagasaki City, Hyogo Pref., central Japan. Then, we designed an ecological network plan to improve biodiversity in an industrial area on reclaimed grounds. At last, we proposed some planting plans in a small factory, in order to create stepping stones on a gap of green spaces.

Housing reconstruction projects have been taken by the Government of Sri Lanka for the victims since the 2004 Sumatra Tsunami. It is chronologically divided into three stages (Emergency shelter, Temporary House, and Permanent House). The authors conducted a field survey in March 2006 to understand the recovery conditions, and obtained data set, which had been collected for 13 months after December 2004, by Rebuilding and Development Agency. It shows about the construction status of Temporary House and Permanent House. This paper demonstrates regional transition of the Temporary House construction in comparison with Permanent House.

Public awareness of risk management to the tsunami disaster has been increased since the 2004 Sumatra Tsunami. Making hazard map is one of the essential countermeasures for the local governments in Japan. Japanese government directed the local to make the maps in 2004 because only 9.6% of the coastal areas prepared them. The authors investigated the making condition of the tsunami hazard maps in August 2006, which were published through Internet. This paper reports how much governments prepare the maps and compares the contents.

Today, the geotechnology is one of the significant fields in the digital earth era. It must change how to record the historical transition of urban recovery process using the cutting edge technologies and spatial information data. This paper demonstrates a trial of making urban recovery archive of Tokyo based on Google Earth as one of the case studies. The digital archive consists of 119 maps/pictures from 1838 to 1997 of some of the important areas in Tokyo (Marunouchi, Otemachi, kyobashi, and Nihonbashi), which present its dramatic historical change including the recovery process from the 1923 Tokyo Earthquake and from the destruction due to the World War II. Using some functions (overlay, timescale, and place mark), it is possible to compare different maps.

The purpose of this study is to clarify relations between town image constructed by the media and real towns. This study focused on spatial distribution of information on stores, especially eating and drinking establishments, and measured distinction between town image in terms of stores on the magazines or on the Internet and real towns. The coefficient of specialization was used to show to what extent each medium pays attention to each genre of stores and to each region. First, information magazines were analyzed which many people use for searching store information. Second, a store information website on the Internet was analyzed which is easy to access and on which impression of visitors to the stores can be posted. The analysis showed that each medium has its "favorite" genres of stores and districts, and that the town image on the media is different from real towns.

This study aims to forecast the prospective number of households and house stock of Tokyo. First we paid our attention to the relation between the house stock and the household composition, and established scenarios of newly established houses according to existing households forecast. Second, we simulated the relations between the number of households and house stock by assuming the distribution of building life of houses. As a result, houses more than 30 square meters in particular remain in downtown area and supply of houses under 30 square meters are insufficient in Middle Tokyo, in the case that houses are established by the same amount as present. In addition, detached houses get older mainly in 23 wards and condominiums get older in downtown area, in the case that the quantity of newly established houses are coordinated so as to meet the population.

Currently, necessities of building height control are increasing because of the mansion conflicts. I analyzed contents and process of the height control zone including a maximum of height as a study of the regional designated city in Japan. As a result, it is necessary to show a designated reason and designated contents clear and a designated merit. In addition, it is necessary to flexible correspondence to the decision that I called the reflection of a citizen's opinion and after the decision that I called reflection of other systems utilized.
