There are some researches on behavior remaining at home despite the risk of danger from earthquake-induced tsunamis. However, there are few researches on difference of the behavior considering habitant attributes such as their household characteristics, type of house, regional condition, etc. This study aims to clarify the characteristics of the evacuation behavior of habitants in the tsunami inundation hazardous areas using a large scale questionnaire survey.
 The questionnaire was distributed to habitants living in the tsunami inundation hazardous area following the Nankai Trough massive earthquake based on damage estimations published by the national cabinet. The areas of focus include the following 13 cities from Kanagawa to Miyazaki Prefecture in Japan facing the Pacific Ocean: Kamakura City, Zushi City, Fujisawa City, Shizuoka City, Shimizu Ward in Shizuoka City, Nishi Ward and Minami Ward in Hamamatsu City, Iwata City, Tsu City, Matsuzaka City, Ise City, Wakayama City Kochi City and Miyazaki City. Given the broad location coverage of this study, the questionnaire survey was conducted through the internet.
 The questionnaire comprises three parts: questions about respondent attributes, questions about respondent houses, and questions about respondent behaviors they will choose after a large earthquake occurred. Firstly, respondents answer their home address, gender, generations and whether or not they live with handicapped family members. Next, respondents answer the type of their house: detached house or apartment buildings, number of stories, and whether they own or rent. Finally, respondents choose their evacuation behavior after a huge earthquake by choosing one behavior from a set of choices provided for two specific scenarios: 1) earthquake occurs at noon, and 2) earthquake occurs late at night. The behavioral choices include: staying home, moving to a school, moving to another residential building nearby, moving to higher ground outdoors, and so on.
 Within the 13 cities surveyed, there were a total of 1103 respondents. The responses were aggregated by attributes and analyzed. The analyses revealed that, after large earthquakes, people living in detached houses tend to stay home, while those living in apartments tend to evacuate; respondents who rent are more likely to evacuate than those who own their home; respondents living in high-rise apartments tend to stay, while those living in low-rise buildings tend to evacuate; and elderly people are more likely to stay home than younger people. In addition, people living with handicapped family or with children tend to evacuate. These results also demonstrated a difference of the evacuation behavior among the 13 cities in the danger of tsunami inundation.

This study proposed an evacuation shelter choice model from great tsunami by using the actual behavioral data collected by the survey of the MILT in the Great East Japan Earthquake. The behavioral data in the flat land of Sendai-city, Natori-city and Iwanuma-city were analyzed. As a result, it was confirmed that "direction to shelter", "distance to shelter", "height of shelter" and "footprint of shelter" strongly affected choice of evacuation facility. The covered areas of shelters, where each shelter has the highest choice probability, were drawn by using the estimated model formulas. Compared with previous models, it was shown that the model of this study can make highly accurate covered areas of shelters. When it comes to layout of evacuation shelters, it is necessary to consider scale of shelters and distance between shelters in addition to choice behavior of evacuees on foot and choice behavior of evacuees by car.

This paper reports evacuation facility choice behavior for Tsunami evacuees in coastal areas of Miyagi prefecture, based on the data of Archives for Reconstruction after the Great East Japan Earthquake. The choice behavior was modeled by using a logit model. This model is constructed considering psychological cost of evacuation, distance from evacuee to evacuation facility, height of evacuation facility, footprint of evacuation facility, and the height above sea level of evacuation facility. We compared the sphere of disaster evacuation by logit model, the sphere of voronoi diagram and the sphere of voronoi diagram with a restricted direction to facility.

This program was designed to provide students whose major was Architecture in Japan with a unique opportunity to working environments at architectural offices with architectural professionals in the United States. Through this experience, participating students were able to get acknowledgement showing they could seek employment opportunities throughout the world after graduation from university. The American Institute of Architects Japan, volunteer students, architectural firms in the United States and Japan Supporting Board organized this program for students who were interested in working throughout the world in the future.

This study aims to reveal relative positive or negative living environment within the areas which have different physical environment. Focused on areas consist of the five kinds of areas which are located in Tokyo central and suburban area. This study conducted by questionnaire survey about dwelling evaluation of town to residents living there, and compared the result and tried to finding difference between each area. The result revealed differences among areas in term of following two points: (1)Tendency to answer to satisfaction of habitants to dwelling environment of town, (2)Some keys that how should we do urban planning to get better dwelling environments.

The transport share of cars is rising year by year in local cities. The number of large shopping centers is increasing in the suburban areas. Therefore, the range of shopping behavior has been broadening and decentralizing. Some former city centers have lost appeal as the shopping sites and declined. In this study, we grasped the behavior to visit shopping sites in the suburban area. In the area, there are difference by the generation, having privately-owned car or not and the place of residence in characteristics of the behavior of visiting shopping sites. In addition, we made choice model using a logit model and revealed its characteristics.

This study aims to make a choice model of tsunami refuge facilities for visitors. We interviewed visitors about the choice of refuge place when tsunami disaster was alarmed, and the reason of choice. We made choice model of tsunami refuge facilities based on multinomial logit model. This model is constructed considering psychological cost of refuge, distance from refugee to refuge facility, distance from sea to refuge facility, height of refuge facility, capacity of refuge facility, building area of refuge facility and with or without river on the way to refuge facility. This model involves the utility value of tsunami refuge facilities for refugee who changes a place on coast line and who is in coast line. We have determined factors which affect visitors' choice of facility. By using the choice model of tsunami refuge facilities, this study has quantitatively revealed which facilities are chosen.

These days, in an inner-city area of Tokyo, mixed districts with residential and commercial use have increased because there are a large number of actions to compact city and large-scale complex development. This study aims to reveal the resident' evaluation of mixed land use. This study conducted questionnaire survey about the evaluation of living environment to residents living in the district of mixed land use and analyzed the result of the evaluation. This study showed the positive/negative factors of living environment in terms of the degree of mixed land use and historical land use. As a conclusion, this study considered that mixed land use have different effects on living environment according to the balance of commercial use and residential use.

本研究は、視覚障害者および晴眼者、車輪がある機器が走行する場所においても、お互いの障壁とならない利用環境を作り出すことができる歩行誘導床材を設計・製作することである。そして、建築物内において、受付や窓口から職員などによる誘導を行わなくても、視覚障害をもつ利用者が目的地まで行くことができ、施設の人的コスト削減につながることや、病院や福祉施設の他、不特定多数の歩行者や機器が走行する施設内（例えば、空港や駅舎）において施設利用者の利便性を向上させることを目指す研究である。 2021年度に実施することになっていた内容は、1.歩行誘導床材の形状設計と床材の試作、2.歩行誘導床材の歩行実験ならびに評価である。これまでの先行実験や先行研究を踏まえて、複数の形状を検討して、床材を製作した。また、建築物内に歩行誘導床材を敷設して、歩行しやすさ、車輪を有する機器の走行評価実験を行った。その結果、視覚障害者および晴眼者、車輪がある機器が走行する場所においても、お互いの障壁とならない利用環境を作り出すことが可能な歩行誘導床材の形状を見出した。そして、本年度の研究実績により、概ね歩行誘導床材の形状を特定するに至った。一方、歩行誘導床材の歩行実験ならびに評価を踏まえて、製品化や各所への設置に至るまでの課題（素材、表層デザイン、耐久性、メンテナンス性）も見つかったため、今後さらなる改善を図る。また成果報告の詳細を研究成果に示す。
