In the design of public cultural facilities, there are an increasing number of examples of design methods that incorporate the users’ ideas at the architectural design stage in order to promote active use.
Our laboratory has collected 70 cases of participatory design from all over Japan. The following participatory design practices were implemented in our laboratory, and the effectiveness of participatory design was verified through analysis of user opinions and post-completion evaluations of these practices.
・Kudamatsu City Community Exchange Center (2013)
・Okayama Prefectural Doctor’s Hall (2015)
・Sanagouchi Village Office (2017)
・Kashiwa City Southern Neighborhood Center (2018)　

In order to ensure safety during construction and to assure quality and performance of buildings, I am conducting research on methods to predict and to evaluate deformation of ground and structures accurately.
Also, to reduce cost, period, and environmental load of re-building, I am researching survey or evaluation methods of existing piles and foundation design reusing them.
In case of disasters such as earthquakes or heavy rains, I quickly survey on site, analyse the cause of damage, and utilise the results for subsequent disaster prevention and mitigation.

One of the important roles of the Building Services Engineering, the follow things must be compatible.
· Building comfort environments for users.
· Adopting energy conservation techniques for the global warming-control measures.
Air Conditioning System : Explaining the effect of natural ventilation by the Computational Fluid Dynamics program.
Plumbing System : Recently, the follow things are realized.
· Water consumption decreases by using water saving plumbing fixtures.
· Booster pump systems increse.
Therefore, I explain the instantaneous flow rates and study the new design method for water supply system.

My spetial field of study is earthquake resistant structure. The way of my study is at first understanding of destruction mode and strength of structure by experiment , and next establishing design method by simulating the experimental results by analysis.
In 2015 I took up my new post of professor of Okayama University of Science, I was beginning of study of Tublar truss structure in steel with locally company. And in 2016 I was beginning study of Base isolation structure and Seismic controle structure by using the small vibration table.
I am planning to study of new structure of minimizing damage under large eathquake expected in the near future.

By conducting experiential surveys and research with an emphasis on fieldwork in the living environment, we will conduct practical research in collaboration with industry, government, and academia for the revitalization of living environments that people can feel enriched by.
The following are some of the studies we have conducted so far.
Practice and verification of the “Two-stage renovation experiment of public rental housing (UR Freestyle House)” conducted jointly with the Urban Renaissance Agency.
Co-sponsoring the 3rd Renovation City Planning Conference @ Nagoya 2017 in collaboration with the Renovation City Planning Center, Inc.
Co-hosted “Hong Kong-Tokyo Collaboration Workshop,” an international exchange workshop in collaboration with the Hong Kong Polytechnic University

Researching relevance between Space Design and Perceptive Structure focusing on both mentally and physically comfort for human which define as “Architectural Studies of Human Science and Environment” through multiple environment.
Due to analysis discussion of the case from ancient to modern time, if we think about design method of comfortable architectural space to capture from “perception” perspective, I believe there are not only five senses but also it considered as “Physical sense design method” which is composed by 10 specific categories of integration of various complex perceptive. Furthermore to capture from “space” perspective, intermediate space such as porch(Engawa) still have an effective impact. And also if we look at water feature(Suiban), to induce complex perception is the element of both mentally and physically comfortable space design.

The way of manufacturing is undergoing major changes. One of the changes is co-creation. Development of a new manufacturing method beyond the gap between the creator and the user is a big challenge.
In my laboratory, I am studying a method to eliminate the barriers between creators and users as much as possible using Stress Index, Virtual Reality and so on. And we aim to construct a place where co-creation is possible.

The landscapes of traditional townscapes and villages are based on the natural conditions of the land, such as climate and topography, and are the tangible manifestations of social characteristics such as history and livelihoods, which have been inherited through traditional lifestyles and local traditions. In our laboratory, we are conducting research to clarify what kind of background has formed such a beautiful landscape, and what kind of elements it is composed of, fucusing on the characteristics of the traditional architecture of the region. We are also examining methods of heritage conservation that involve local residents in order to inherit these cultural heritages to future generations.

It is verified that about 80% of 6,400 victims by 1995 Hyogo-ken Nanbu earthquake are caused by collapse of a large number of wooden houses. So after that earthquake a very large number of researches on seismic design of wooden houses have been preformed. Our research group has worked on various experimental studies on timber structures, such as full scale existing houses, shear walls, frames, members, and also we often participate in damage survey in big earthquakes.

We are developing and verifying building methods and equipment technologies for the realization of comfortable and energy-saving construction. Analysis of meteorological data to utilize natural energy is also one of the important tasks.
We are conducting research toward zero energy architecture and the realization of cities.

Study and practice on design methods of architecture in the context of urban space, public space, strategic urban regeneration by micro-intervention.
The main emphasis of my laboratory is to grasp architecture in the context of urban space and social situation, and use this for the basis for constructing both a new design theory and practical architectural projects.
