Field of research: Architectural history and design
Field of specialization: History of cities, history of architecture, preservation/restoration planning
Our laboratory is conducting investigations and research - from a comprehensive perspective
encompassing art, culture, technology, living and economics - on the history of architecture and urban
design while always going beyond whether a spatial design is good or bad, and considering how "space
and society" relate to each other. In recent years, there has been a trend toward
environmentally-friendly town development making use of historical buildings and streetscapes, and we
are actively working toward this type of preservation/restoration planning for historical
Our main recent research topics include: research on the urban space formation process in Edo and Tokyo, research on spatial composition and view preservation in historical streetscapes, comparative research on historical cities and urban housing in East Asia, research on preservation/restoration of modern architecture, and research on transformation of festival spaces in modern cities.
Field of research: Architectural planning
Field of specialization: Architectural/City planning, architectural design
When taking the practical standpoint of designing a single building in a modern city, we believe it is important to review areas and urban spaces as architectural units and their aggregates, and draw on that when introducing planning technology to create a more fulfilling environment. In this laboratory, we conduct thorough fieldwork to develop the ability to "read" real-world architecture and urban spaces, and we evaluate spaces by collecting objective data and using mathematical analysis techniques. Our recent research topics include: research on the spatial configuration of urban housing in Asia and Europe, research on spatial forms in buildings and cities, and research on space design in town development. In our research on urban housing, we have traveled to Tokyo, Kyoto, Hanoi, Barcelona, Seoul, Beijing, Shanghai and Hong Kong looking for the high-density housing which is rapidly being lost in the process of urban development. As a space design for town development, we are working to restore the Fukagawa shopping street in downtown Tokyo.

Main Research Themes
(1) An Analysis of Publicness as an Actual Theory of Architecture and Cities
Analyze the city's character through the extraction of public (free) space within and outside the urban architecture.
(2) Media Analysis as a Social Construction Theory of Architectural Design
Analyze the discourses and photographs in architectural journals, popular magazines, and newspapers. The discourses on the subject are extracted and analyzed to understand how people understood the theme over time.
(3) An analysis of the following issues as the theory of actuality or the social construction of architectural designs.
Gender, vision, others, consumption, ethics, class, and globalization social are areas that we have not yet tackled. Still, we would like to continue our research in these areas as part of the "sociology of architecture" field.
(1) Build your design ability.
Design is, in a sense, a kinetic ability. The accumulation of architectural vocabularies and the adaptability of architectural vocabularies to quickly find a solution to a given condition and the ability to make decisions are essential. So it is crucial to do so by the numbers, whether through competitions, proposals, workshops, or If I get a chance, I would like to design a project using the actual project as a material. The first goal of the laboratory is to master the techniques of design in the process.y is to learn the methods of design in the process.
(2) Practice to think
The above practice is not fruitful if done in the dark. The theory is indispensable there. But what exactly is the design theory? The goal of the structure is a clear indicator of "unbreakable" and "comfortable" in the case of the environment. There is no such thing in Beauty. It is a society that decides Beauty at a particular time. In other words, design theory is about judging the appropriateness of a design in an era from various perspectives. Our laboratory tries to explore the possibility of applying it to architecture through reading the literature on the basic concept of design.
(3) Develop an international mindset.
To learn how to think and design abroad, to look at your design more objectively, I strongly recommend studying abroad and internship abroad on your own.

Field of research: Architectural history and design
Field of specialization: history of modern architecture, preservation/restoration planning, design
The city of today is not something that just appeared one day, but an extension of all the past that came before it. It leads to the future. In this laboratory, we conduct research on urban and architectural history with a focus on modern Japan and East Asia. It is. At that time, we consider the relationship between the space and the society behind it, rather than the good or bad of the space as it exists today. We will apply our research on architecture and the city from a historical point of view to the future of towns and regions, the city I would like to connect this to the design of the space.

Field of research: Building environment, building equipment, computational fluid
Field of specialization: Ventilation equipment design, ventilation efficiency, CFD application for indoor airflow
Human beings are said to spend over 80 percent of their lives indoors. Generally, people are not very aware of the air quality, but in these days buildings are increasingly airtight, there are major issues regarding the risk of air suffering health, providing adequate ventilation to ensure good air quality, and taking measures so that fresh air reaches the inhabitants of a building. As part of combating global warming, we ask: what sort of openings should buildings have to provide natural ventilation in the summer so people can live without air-conditioning system? What sort of building openings can be opened worry-free during sleeping at night? To address these issues, we use experiments, measurements, computational simulations and other techniques to conduct research on the best approaches for healthy, comfortable and highly energy-efficient buildings.
Field of research: Environment engineering
Field of specialization: Thermal environment, air-conditioning equipment
We are conducting research on methods of air-conditioning control using fewer resources more efficiently, while maintaining the indoor environment in a healthy and thermally comfortable condition. To achieve that, we are using measurement of actual buildings and computer simulations to research architectural design techniques such as reinforcement of insulation and appropriate placement of windows, and methods of evaluating such techniques. We are also conducting research on methods of coordinating air-conditioning with the opening and closing of windows in homes, and research on methods of optimal control for air-conditioning systems in large buildings.
Field of research: Building structure, earthquake engineering, steel structure
Field of specialization: Seismic isolation and damping, optimization theory, health diagnosis
Earthquake safety requirements of cities and buildings are extremely high in societies like Japan which have attained a high level of development. In order to achieve safe and secure cities and buildings, we are developing technology for seismic isolation and damping to protect against building damage even during large earthquakes and to enable use of buildings immediately after an earthquake. In particular, we are developing optimal control design methods for efficiently preventing building damage, and high-performance low-cost seismic isolation equipment for single family homes. To achieve that we are conducting basic research to elucidate the vibration characteristics of buildings, and examine methods of simulating the behavior of buildings and cities during an earthquake. We are also studying methods of managing the earthquake risk of cities and buildings, and detecting building damage.

Field of specialization: Performance design methods, structural mechanics, applied mechanics, highly non-linear problems, hybrid experiments
On many occasions in recent years, people have experienced the nightmare of human lives being lost in building collapses due to unprecedented natural and human-caused disasters. These tragedies show us that building performance requirements continue to change with the times. When discussing safety, the single indicator of conventional quake-resistance is not enough. We are faced with an era where we need to consider new concepts in design. Massive physical and economic losses were also sustained due to these disasters, and society's need to preserve property has increased. Furthermore, awareness of global environmental problems is rising, and we now need to discuss the potential for long-term sustained use of buildings. To address these next-generation performance requirements, we are working to restore and effectively use steel-frame structures as existing stock. We are also conducting research on restorability with the aim of continuous use, and renewal of structure performance, while taking into account the option of hybrid structures, which are primarily steel-frame structures.
Field of research: Building materials
Field of specialization: Conservation of RC buildings, recycling of building materials, creep and shrinkage of Concrete
Performance of building changes with time. Maintenance of historical buildings is a matter of social
concern. Research on conservation of building from view point of materials is performed at laboratory.
On the other hands, environmental impact of building materials is significant. Hence
environment-conscious materials and systems is a key for sustainable development of the world. Use of
by-products in cementitious materials is an effective way to achieve this purpose. At laboratory,
following research topics are prepared.
1) Conservation and renovation of historical building from view point of material durability
2) Service life prediction of buildings
3) Maintenance of building exteriors
4) Durability of damaged concrete structure
5) Development of new building system with rammed earth
6) Control of cracking RC structures
7) Repair of deteriorated timber
Field of research: Applied mathematics, Structural engineering
Field of specialization: Applied mechanics, Optimum design, Computational solid mechanics
We study about new design methods by the mathematics-based approaches from the perspective of structural performance, economy, designability and workability as follows:
(1) Structural optimization of buildings: We develop structural design methods of buildings by structural optimization approach that minimizes a cost function for given design conditions. In this topic, we concentrate on assessment of seismic risk and/or life cycle cost, and artificial intelligence in design.
(2) Robust design optimization: We aim realization of rational robust design of structures. Structural optimization approach can serve as a useful framework of the robust design. We study what type of structural system has high robustness and how robustness of the system is improved.
(3) Structural morphogenesis of spatial structures: To propose a rational structural design method of spatial structures, we focus on the relation between form resistance and vibration control of the structure. We also study mathematics-based design method of free-form shell structures, membrane structure, tensegrity and cable net.
