In this study, we evaluate the development in Tomakomai port utilizing a policy evaluation model. And, we proposed a new measurement for a posteriori evaluation. For evaluating a development process, we propose a process evaluation model. It is a feature in this study that we utilized a newspaper and an interview survey for evaluating a development process. Although some suppositions in the original plan are not realized, the result in the logic model is obtained by revision of the development process. As a result, it is clarified that a proposed model is one of the effective posteriori evaluation models.

Fuji-bashi, completed in 1915 over the Fuji River in Sizuoka Prefecture, is probably the longest span suspension bridge as well as only one railway suspension bridge in Japan before the World War II. However it's existence has been forgotten for a long time. The reason of oblivion will be as follows; that is, it was constructed by a private paper-manufacturing company, and it was used only four years until it was destructed in the stormy night with intent to save disaster. The purpose of this paper is to regain its reputation, and try to emphasize that Fuji-bashi is one of the important structures in the history of civil engineering of the modernized era in Japan. The paper contains lots of original data concerning its construction.

The Hennebique Company, funded in 1892 by Francois Hennebique in France, expanded its organization very quickly and diffused a reinforced concrete technology widely the world. It is often explained that the reason why the company could grow up so rapidly is due to the ‘Hennebique Systemè’, one of the idea to reinforce a structure of concrete. But it does not seem to be enough to clarify the reason of the rapid growth. This paper analyzes the process of the Risorgimento bridge construction from the viewpoint of technology transfer. For that, a series of letters mainly exchanged between the company and one of the agents in Turin (Italy) discussing about the construction problems is analyzed. That will illustrate a capability of the organization of the Hennebique Company in the field of the technology transfer and technology.

The port of Misumi is one of the oldest Japanese modern ports, built by the initiative of Meiji goverment. In spite of its historical importance on the chronological level, the appreciations by historians are rather divergent: a beautiful masonry work realized thanks to the marriage of the traditional and Western techniques, the badly selected site for which commercial activities stagnate with the passing of years, etc. In order to validly define the historical value of this realization, this paper analyzies the archives, inedite or not, and clarifies the process and the ideas of the planning and constrauction of this port.

This study focused on the development of Uji City under the modernization before the consolidation in 1951. Before modern age, this area had been famous for the sightseeing and the tea plant. Under the modernization, some infrastructures such as road systems, railway systems and electric generation systems were constructed in this area, and had consisted or sustained the image of this area.
This study analyzed the influence of infrastructure toward urban landscape, urban life and the image of the city, and then clarified the city planning and management of the Uji City on the process of the modernization. The image of Uji City itself was not made revolutionized by the infrastructure, but elements of the image were updated taking advantage of the infrastructure. Therefore, the image of Uji City constituted before modern age have been succeeded.

Shinto-shrines were one of the most important elements of Castle town in Japan, such as creeks and streets. We consider them impossible to move because they are established on their site. However, in Edo city, they were frequently moved by the governors from the development of the city to the end of Edo era. The purpose of this study was to understand how they treated and located the Shinto-shrines from the viewpoint of city planning in Edo city. In the study, the location and transference of 110 shrines were plotted on the map, the reason of transfer, the condition of the site, and the tendency of location were analyzed. As a result, the study has shown that the principles of Shinto-shrines' location was changed as following: 1) before Edo era, they were located as religious element and indirect government system, 2) in the beginning of Edo era, the construction of the castle preceded the shrine location, 3) after the middle of the era, they were treated as the stock of the land from the standpoint of city planning, but the religious meaning was not lost to the last. These results are unique and not mentioned in the previous study of castle town.
