An Eight-Mat Room of Chosen Woods
Northwest of the main house at the former Tanaka Family Residence, set at an angle so the buildings step past one another (gankō, a staggered "flying geese" plan), stands the tea room (chashitsu). It is a small single-storey building, its west side joined to the north storehouse, raised around 1919 as part of the compound the Ōmi merchant Tanaka family put up in the Taishō era.
The family traded as Tagen in hemp cloth and mosquito nets, and the tea room is where that wealth turned toward refinement rather than display. The building measures about 5.8 metres along the ridge by 6.0 metres in depth, roughly 35 square metres, roofed in hip-and-gable form (irimoya) with pantile. Its east gable is turned to face the garden and edged with a low veranda (ochi-en), giving the room a composed, settled character on its garden side.
The Making of the Alcove
The interior is an eight-mat room, and its north face is divided into three parts to hold the display alcove and its neighbours. Here the carpentry becomes deliberately expressive. Round bamboo, a suspended lintel of pine (otoshigake) and a range of other prized timbers (meiboku) are worked into the setting around the alcove, so that the fittings themselves carry the design rather than any applied ornament.
This is the vocabulary of the sukiya manner, in which a tea space is built from carefully selected natural materials whose grain, curve and colour are chosen and combined by eye. A merchant family versed in textiles would have understood such distinctions in material, and the room reads as the work of clients who cared about the choice of every post and lintel.
The Agency for Cultural Affairs registered the tea room as a Tangible Cultural Property serving as a model of design. Its value lies less in size than in the concentrated quality of its interior, and in how neatly it locks into the staggered plan of the compound, sharing a wall with the north storehouse and presenting its finished gable to the garden.
Seeing the Tea Room Today
The residence now operates as Ōmi Shōnintei, a reservation-only restaurant serving Lake Biwa freshwater fish and seasonal dishes, in business since 1994. The buildings stand in a near-straight line from the street, north storehouse, main house, tea room, corridor and great hall, with the garden wrapping around them. The tea room sits within that sequence, and a visit reveals how the interior treats natural material as the subject of the design.
Look for the round bamboo and the pine lintel in the alcove setting, and step to the east side to see the low veranda where the gable meets the garden. The garden, laid out in 1933 by Yamamura Bunshichirō of the Hanabun firm in the Donketsu tradition, gives the small room the wider setting its makers intended.

Q&A
- What makes the tea room notable?
- Its interior. The eight-mat room's alcove setting uses round bamboo, a pine lintel and a variety of prized woods, so the building is valued for its finely worked details rather than its size.
- What is the "flying geese" plan?
- A staggered arrangement (gankō) in which buildings step past one another rather than lining up flush. The tea room is set at an angle to the main house and joined to the north storehouse.
- How big is the tea room?
- About 5.8 metres by 6.0 metres, roughly 35 square metres, a single-storey building with a hip-and-gable tiled roof. It is the smallest of the five registered structures.
- Can I enter the tea room?
- Access is as a guest of the Ōmi Shōnintei restaurant, by reservation. There is no separate museum entry, so which rooms you see depends on the visit.
- When was it built?
- Around 1919, in the Taishō era, together with the main house and great hall. The garden it faces was completed later, in 1933.
