The two large, highly enclosed galleries were arranged on the first floor and covered with soil; consequently, they appear to be underground. A small, grass-covered hill was thus created on the once-level site. On top of the hill, open spaces such as the entrance hall and café are located beneath a lightweight roof. The storage, wrapped in a metallic membrane, seems to float above the roof, and as the most prominent feature of the building also serves as the symbol of the museum. Adressing the Shosoin, the famous ancient repository located across the street from the site, this project offers a new "Shosoin of the future."

The fire station program is located in the upper volume, supported on the thinnest possible columns. Circular voids cut through this volume to connect the two spaces and programs. The juxtaposition of the thinness of the columns with the volume above impresses upon the viewer the lightness of the figure of this new public structure.

The site is a leveled hilltop, deep in the mountains, with a sports park nearby. The building is for the most part single-storied, and is used as a meeting hall for the townspeople and for simple sports, with two mini-handball courts inside. Inside a rectangular volume articulated by glass façades, an irregularly shaped wood structure covers the courts. Seen from outside, the building looks as though a giant artificial bush was constructed in the middle of the mountains. The building is a mix of wood and steel structural systems: the glass façades are stabilized by the steel ties connected back to the wood structure. The lightweight steel ties (60mmx60mm) are spaced at 1-meter intervals, and inside wood structural members are 120mmx210mm. The roof is also made up of lightweight steel members, in a 2-meter grid. Under this roof structure, a grid of wood members, rotated 45 degrees, is lined up, and the two separate systems are tied to make a truss, forming a 22-meter span. Because the lower chord of the truss is rotated 45 degrees from the upper chord, it is possible to push and pull on the web of the truss, thereby adjusting the height of the ceiling. In other words, when extra height is needed for some program, one can adjust the height of the ceiling. In order to emphasize wood as the building material this building is constructed primarily of wood and steel.

The architects designed a large-scale version of a conventional wood-construction structure, in response to the requests of not only the town of Seiwa, but also the Cultural Agency and the Forestry Agency. The structure was made as large as the Building Standard Law permits; that is, the eaves are nine meters in height, and the maximum height is thirteen meters. Wood beams are layered, as has been the practice with traditional wood-construction since the Nara period. While there are over 1,000 Noh stages in Japan today, it is hoped that this facility, with a seating capacity of 200, will become the representative Noh theater in Kyushu. Architectural Data Name: Seiwa Bunraku Puppet Theater Location: 152 Haraguchi, Ohira, Seiwa-son, Kamimashiki-gun Main function: bunraku theater and museum Site area: 10,200 square meters Building area: 856 square meters Total floor area: 781 square meters Extent: two aboveground floors Structure: wooden construction Construction period: December 1990 - March 1992 Total construction cost: 436 million Kazuhiro Ishii 1944 Born in Tokyo 1967 Graduated from Department of Architecture, Faculty of Engineering, University of Tokyo 1975 completed doctoral course, University of Tokyo; completed master's course, School of Architecture, Yale University 1978 Incorporated Kazuhiro Ishii Architect & Associates Has been lecturer at Faculty of International Studies, Waseda University; University of California; Nihon University; Yale University, Osaka University; University of Tokyo; Japan Women's University 5 Excursion Ⅱ ① Mt. Aso Volcano Mouth Mount Aso, the largest caldedra in the world, is composed of five mountains; Nekodake, Takadake, Nakadake, Eboshidake,and Kinedake. The caledra is 1592 meters in height, with a width of about 18km in the east–west direction and about 25km in the north-south direction. ③ Mokkonkan 1988 Hideaki Katsura Architectural Summary This is a training center with a unique wooden design construction method known as "Box-Beam", a design copied from traditional roof designs in the Oguni area. This is a gathering place for leaders of different towns to discuss town development. Mokkonkan facilities include meeting rooms, training rooms and lecture halls.

Approximately 100 students were enrolled at the time of the project, and that number was decreasing. The architect conducted a workshop with local residents, and discussed the possibility of using the school for more purposes. By situating the gymnasium between two existing buildings on east and west side, the surrounding galleries function as a circulation route through the whole school. By transferring special classrooms like kitchen and library to the east wing, the eastern part of the school is reorganized for social education and community use. Wood is used for both structure and finish in order to express the importance of forestry in the area. Cedar box trusses were used on the roof of the gym. Clerestories were installed between the enormous trusses to let in natural light, which is reflected off cylindrical panels. A soft light fills the arena, which is covered with wooden louvers. The color and intensity of light change gradually according to the movement of the sun and the weather.
