Profile

In September 1994, I was born in Chiba Prefecture, Japan. Since April 2021, I have been appointed as Research Associate at Faculty of Science and Engineering in Waseda University. I have the Master Degree of Engineering (Waseda University, Mar. 2019.) and the IPEJ lisence as Engineer-in-Training (Urban and Regional Planning of Civil Engineering Field).

My research fields are "Civil Engineering History", "Landscape and Civil Design", "Urban and Territorial Design" and "Community Planning". Currently, I'm engaged in historical research on the planning and design of urban expressways in Japan after WWII and practical activity on community planning utilizing local water-related infrastructures.

  • A REPORT ON THE CAREER AND URBAN PLANNING WORKS OF TAMOTSU MACHIDA, AN URBAN PLANNER

    Hironao KOZAWA, Yoh SASAKI

    Journal of Japan Society of Civil Engineers, Ser. D2 (Historical Studies in Civil Engineering)   77 ( 1 ) 38 - 52  2021.05  [Refereed]  [Domestic journal]

    Authorship:Lead author, Corresponding author

     View Summary

    ■Abstract
    This report clarifies the career and urban planning works of Tamotsu Machida (1903-1967), who worked as an urban planner of the Ministry of Home Affairs before World War II (WWII) and the Ministry of Construction after WWII in Japan. The main points based on the making of his chronology and the analysis of documents written by him are as follows; 1) In Postwar Reconstruction Urban Planning, he worked as the center figure of the engineers in the War Disaster Reconstruction Institute after WWII and the Ministry of Construction by utilizing the experience and knowledge of the Tokyo Reconstruction Project after the Great Kanto Earthquake. 2) In Capital Construction Planning, he worked as a secretary general in the Committee on Capital Construction Planning. Especially, he was instrumental in Satellite city Development Plan and Metropolitan Expressway Plan in Tokyo by utilizing his experience in the prewar research on regional planning and the postwar inspection tour to the US.

  • A STUDY ON BRIDGE DESIGN BY OSAKA MUNICIPAL ELECTRIC RAILWAY PROJECT IN OSAKA CITY BEFORE WORLD WAR II

    Hironao KOZAWA, Yoh SASAKI, Hiroshi MATSUMURA, Yasuhiro KUROYAMA

    ■Abstract
    This study aims to clarify the thought and the characteristics of bridge design developed by Osaka Municipal Electric Railway Project in Osaka City before World War II. The results are as follows; 1) There might be some ideas to unify the structural type and the construction cost of bridges for each railway route. 2) There are three main characteristics of bridge design from perspectives of architectural design and urban design; one is the unification of structural type and handrail design in bridges on the same route, another is the variety of handrail design in bridges on the specific route, and the other is the limited adoption of arch bridges, which were considered in the geological conditions and the importance of locations where bridges were built.

  • Information design for understanding the regional environment as a base of disaster awareness -A case study of booklet design for a wetland environment-

    Yoh SASAKI, Hironao KOZAWA, Takumi WATANABE, Kodai YOSHIZAWA

    Proceedings of CWMD International Conference    2019.09  [Refereed]

     View Summary

    ■Abstract
    It is possible to consider flood as a natural phenomenon, while flood disaster appears to be a social phenomenon to cope with. Besides the social and natural aspects, the damage of biosystem and landscape should also be considered as the result of disasters. Therefore discussion involving various stakeholders is expected regarding the complexity of the nature of disasters. However, as most effort mainly focus on the issue when the disaster happens, a viewpoint from every day experience is needed. While landscape is one of the most common cognitive images of the environment, it is hard to understand the relations in environmental elements and/or their transitions both in short and long term. Therefore the media to promote the understanding is needed. In this paper, a visual media design is made, in order to help the intuitive understanding of the relations among the environmental elements and human activities. The site Fukushimagata is a wetland located in Niigata prefecture, Japan. The region has a history of continuous reclamation, and simultaneously the largest reservoir serving as a habitat of diverse creatures. Since the establishment of the core activity center in 1997, the facility has been acting as the place for citizens to get close to the natural environment. Meanwhile, as Fukushimagata is expected to work as a pondage, flood control facilities are constructed, and some rice field have been turned back to wetland. However, these flood control facilities are not visible for the recreational users. For example, a large floodgate under construction might be considered as a visually offensive structure, meanwhile it may also be regarded as a mark of the flood control system. Thus the evaluation of the floodgates depends not only on the design, but also on the understanding of the regional environment. Therefore a booklet is designed in order to help people to understand the landscape deeper both in spatial and time scale. It contains various graphics: map showing spatial transition based on HLC (Historical Landscape Characterization) analysis, cross sections to express the water circulation as well as the relation between human activities and water, map of historical marking sites such as shrines and stone monuments, and a bird-eye illustration studded with related elements. A character as a storyteller guides each page. Though the data showing the effect of this booklet has not yet been acquired, we can demonstrate the importance of information design for describing the region.

    ■Abstract
    This paper clarifies the planning history and route planning features of “The Plan for Metropolitan Expressway in Japan”, published as National Capital Construction Committee Notice No.12, April 1953. As a result of the survey of previous research and literatures and the analysis using geographic information systems, the possibility of route selection based on the war-damaged reconstruction plan roads and the similarity with the route alignment of the present Metropolitan Expressway emerged.

  • 大阪市・市電事業で建設された橋梁のデザインに関する一考察

    土木史研究講演集   38   279 - 288  2018.06  [Domestic journal]

     View Summary

    ■論文要旨
    明治末から昭和初期にかけて大阪市が実施した市電事業で建設された橋梁の図面が大量に保管されている.本稿はこの資料を用いて当時の橋梁デザイン思想を考察した.その結果,難波橋や木津川橋・本町橋など市電事業での主要橋梁においてはその重要性に鑑みて構造本体および細部において特段の工夫がなされていたこと,またそれ以外の一般的な橋梁においても高欄の意匠の多様性や大阪市章を廃するなどの創意工夫がなされていたことを具体的に明らかにした.設計者の意図を伝える言説は残されていないが,図面の読み取りからデザインの意図を推測することによって,明治末から昭和初期での我が国の橋梁形式選定手法や細部を含む橋梁デザインの特徴を考察することができた.

  • 戦後土木施設としての首都高速道路の特質に関する一考察

     View Summary

    ■論文要旨
    戦後土木施設が今後文化財指定の対象となることを視野に入れて,その評価軸や観点に関する議論が土木学会においても行われている.本稿では戦後土木施設の代表的な例といえる首都高速道路を対象として,その特質を検討することを試みる.そのためまず首都高速道路の構想から事業化時の概略を整理し,駐車場,建築,地下鉄といった異なる都市機能の一体設計の事例についてその概要を把握した.その上で道路における評価観点を参考にして,都市高速道路の評価観点としては規範性や総合性が重要となる可能性についての試論を提示した.

    ■論文要旨
    大阪市では,明治後期から戦前にかけて行われた数々の都市計画事業により,市内中心部の街路や橋梁等の整備が行われ,近代都市として大きく発展した.本研究では,その発展に寄与した大阪市営電気軌道事業について,都市計画史の観点から考察した.また,事業によって新設または改築された橋梁に着目し,設計図面や構造計算書より橋梁デザインの特徴を整理し,既存研究で示されている近代日本における橋梁デザインに関する知見との対照を行った.その結果,大阪市営電気事業は大阪市内の街路・橋梁整備を促進した最初の都市計画事業であったこと,橋梁は鋼鈑桁・木桁の構造型式が多く採用され,例外的にアーチ橋が採用されていたこと,高欄には特徴ある意匠が施されていたことなどを明らかにした.
