① Yatsushiro Municiple Museum
Toyo Ito
1991
Architectural Summary
In this project, great care was taken to harmonize the building with its relatively low,
human-scaled environment. 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."

② Yatsushiro Fire Station
Toyo Ito
1995
Architectural Summary
As a gesture of opening up to the
inhabitants of the city, the fire station
headquarters is entirely lifted on pilotis,
providing a public space at the ground
floor. 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.

③ Forest Fall Tomochi
Taira Nishizawa
2002
Architectural Summary
For a small meeting hall (about 250 square meters) for a lumber town in Kumamoto Prefecture,
the architect was requested to use local wood and the town’s symbol in the design of the hall.
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.

④ Seiwa Bunraku Puppet Theater
Koichi Ishii
Architectural Summary
This is a theater for a form of bunraku that has been performed in the
Seiwa village since the late Edo period. 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.

④ Oguni Town Kitazato Elementary School Gymnasium
Kaoru Suehiro
2003
Architectural Summary
This was a project to rebuild the gymnasium of an elementary school in a mountain village.
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.

Tom Heneghan
Architectural Summary
The four main buildings of this facility are arranged together with several programmatically
subordinate buildings in a way that allows them to be seen as a group. The site, a pastureland,
determines the relationships between the groups scattered over the extensive site and
between individual buildings. The buildings are perceived as parts of one facility because of
similarity of form and material. Buildings that require large volumes have been formally
articulated in accordance with function or various external factors, breaking down the large
scale of spaces and softing the profiles of buildings in order not to distract from the natural
great beauty of the environment.

⑧ Kumamoto Municipal Shinchi Housing, Block A
Kunihiko Hayakawa
1991
Architectural Summary
Low-rise
apartment
buildings
were
introduced to create a sense of continuity
with the surrounding residential district.
Even the elevations of the five-story
apartment buildings have been treated to
make them resemble low-rise buildings.
Inside the housing project, two- and
three-story architectural elements give
buildings a human scale and eliminate the
usual perception of the south side of
apartment buildings as the front and the
north side as the back. The elongated
five-story apartment buildings could have
easily become impenetrable walls, but twoand three-story high gates, provided at
regular intervals, direct people's eyes
through the buildings toward open spaces.

Riichiro Ogata
1992
Architectural Summary
The apartment buildings, which resemble a pair of whales swimming side by side, were given
undulating facades and windows of different qualities to create greater visual variety. The
project was conceived as a theater, with the mall sandwiched between the buildings as the
stage and the buildings as the audience. The bathrooms were concentrated at the middle of
each unit, enabling the more public spaces of units to look out over the mall. All stairs lead
directly to the mall, assuring communication at every level: family, housing complex residents,
and neighborhood. The "whales" head eastward, bearing a human community.

Yuzuru Tominaga
1993
Architectural Summary
This project proposes a new approach to the design of public buildings. The apartment building
was raised on pilotis along the the ten-meter slope of the site, in order to provide pedestrians
on the sidewalk with views to the north and local people with a communal place. A park-like
space was also created. The apartment building was intended to recreate the small
neighborhood ambience that previously existed in the area. Narrow passageways leading from
the corridor on the north side to the stairways were created, and living rooms were integrated
with terraces. With respect to the structural system, the north and south façades were made
with wall-beams. Bearing walls arranged at right angles to those wall-beams between housing
units, and 25-centimeter thick beam-less panels, form concrete boxes. This system improves
sound insulation between floors and facilitates future changes in the layout of units.

Hiroshi Nishioka
1995
Architectural Summary
The public housing project that used to stand at the site had flourishing plants and various
measures taken by occupants to make their units more pleasant. This created a distinctive
atmosphere, an openness and energy that suggested the vernacular architecture of the warm
Southeast Asian region. The new project evokes that atmosphere with its forms and colors.
Stairs in conventional public housing projects tend to be gloomy, cluttered spaces, but the
stairs in this project have been pushed out of the building proper and opened to the outdoors,
and given different forms and colors to make them easier to distinguish. The stairs also allow
people to look at the view to the north as they go to their respective units.

Kenjiro Ueda
1995
Architectural Summary
Three-story apartment buildings that contain six housing units are adapted to the topography
and connected to form rows on both sides of a pedestrian way. These curve around a large
open space. A series of social groups are expected to develop, starting with households
sharing the same stairway, extending to the street, and eventually the housing project as a
whole. The unit’s L-shaped plan gives the living room exposure on both sides. The individual
building units are made small so as to blend in with houses in the nearby area. The buildings
are articulated in elevation to make them seem smaller than they really are and bent in plan to
create variety. The planted trees and the open space are attempts to recreate the natural
landscape that once existed here.
