Front hall (前広間)

The hall, which is adjacent to the street floor, has a unique structure in which a flat structure is turned around, but the beams are placed one step higher, and the lower part is a transom shoji. It is thought that this is not only for design purposes, but also to prevent structural weakening due to concentration of joint holes on the pillars. In addition, the fittings that partition the halls are generally lacquered obi doors that create a hard atmosphere, but in the case of the Hamamoto family, in consideration of the natural light, the interior space is made to look soft by using fusuma sliding doors.

Great hall (大広間)

The beams on the upper part of the atrium are made of materials of the same size and curvature and are coated with lacquer. It has a unique structure with shoji windows on the second floor above the beams, and the ceiling is a coffered ceiling with black lacquer and a gold leaf surface.

Take it down and build a garden outside. In addition, in the left corner of the front, there is a four-and-a-half tatami mat tea room for entertaining guests.

The design of the alcove and the study room is also innovative, and precious wood is used for the materials, and the highest quality lacquer is applied. The fusuma and shoji screens are made using the best of the techniques of joiners and Kyoto craftsmen. A transom and a rare transom with a painting of yellowtail on pure silk are inlaid.

The ceiling is also lacquered with black lacquer around the rim and neck, and a 2-shaku wide Yakusugi ceiling board is attached.

All the members of each room are made of high-quality wood that has been thoroughly dried without cracks, smooth carpentry with a smooth plane finish, and a high-quality lacquer finish that shines like a mirror.
