URBAN BLD SHINSAIBASHI
This project is a renovation of a 23-year-old building for rent following its securitization. While keeping the tenants in the building, the building experienced functional repair and improvement as well as addition of design attractions including curtain wall modifications in order to create new values of the real estate.

SUNTORY PRODUCTS DEVELOPMENT CENTER
The laboratory and office spaces as the building's main functions are located in columnless areas of about 100m x 20m respectively; this design approach enables the customer to accommodate projects in flux to meet market changes and while rationally providing support functions to cause synergy, communications, and product-based collaborations. This building presents a facility model to enable continuous development of developer companies.

Ubiquitous
Thanks to application of the planned development design system by the Tokyo Metropolitan Government, the applicable maximum height and rate of building capacity were relaxed; taking advantage of this, the site was effectively utilized. The facade facing the quiet residential area in the south was largely curved, and the surfaces of its sash openings are covered by folded plates with holes so that the presence of the building should give a less sense of oppression and more comfortable view.

HARIMA DIVISION, USIO INC.
The management and office building, R&D facilities, production facilities, and the dining hall were once scattered in the site. By accommodating these functions in two buildings connected by a bridge, operational efficiencies are improved, and the integrated facade to materialize the corporate identity was formed.

Ai-City
This office complex has laboratories on the first floor and the headquarters on the 2nd floor. The design of the offices intends to restructure PROJECTSpaces from the viewpoint of intellectual production. The atrium to the east is positioned as a peripheral space inside the office and was planned to be an intermediate zone where traffic and office functions come across in order to improve intellectual production based on tacit knowledge.

FUN HOUSE
The headquarters of a record company. It contains a courtyard that leads to the basement inside. It is aimed to promote the information exchange among employees.

TOWA GARDEN BLDG
This office is composed of a sunken garden surrounded by wooden louver and of two walls on east and west sides. The composition realized a column-free, flexible office space and urges people who work in the space to exchange information freely. It also gives a consideration for external factors, such as heat and noise problems and its context as a residential area.

New Tokyo Headquarters of SANKYO
In order to secure the public benefit of the building in the city, the building floats in the air taking advantage of the diagonal grid column structure inspired by a bamboo basket. In consideration of the environment, it adopts a heating/cooling radiant panel system.

Municipal Building in Toshima
This is a public building. Any architecture of a considerable size in the city has to visually satisfy public benefits. This building meets this demand through two towers facing the park and the wall which acts as louvers.

YNA
The "ship" located at the intersection of the atrium space running in the north-south direction of the building accommodates the technical library, the main feature of the facility. The double glazing structure with DPG and double-layered glass contributes to energy-saving for the air-conditioning.

Redevelopment Project in Takasaki
A redevelopment project of an office building to accommodate the head office of a car sales company and its showroom and a public parking building. Wherever possible, recyclable and recycled materials are used in consideration of environment-friendliness while the finish is warm and friendly thanks to using wooden and earthy materials in addition to metal and glass materials.

Research and Development Center for Santen Pharmaceutical Company
The Center is composed of the Central building with an entrance and a library, the South Research Building and the North Research Building that implies the future expansion. The exterior of the building expresses the image of old city Nara and the corporate image through its materials such as earth, glass and aluminum. The research rooms and central corridor are designed for such uses as meeting rooms or standing conference space to exchange information and intended to vitalize communications among the researchers.
