A Tea House With a Farmhouse Frame
The Tozanso Tea House (東山荘茶室, Tōzansō Chashitsu) is a single-story wooden hospitality building on the Tozanso estate in Kasugacho, Atami City, Shizuoka Prefecture, completed in 1940 and entered on the national register as a Registered Tangible Cultural Property (structure) on August 1, 2016. It sits west of the main house on slightly higher ground, its ridge running north to south, and it was extended around 1975.
The commission came from Yamashita Kamesaburo, first president of the Yamashita Kisen shipping line, who had taken over the villa from the banker Ishii Kengo in 1939. The following year he added both this building and the annex, using the contractor Shimizu-gumi for each. The Tozanso Preservation Society treats the two as a matched pair, built in the same year by the same hands.
Anyone expecting a small Chashitsu and nothing else will find something broader. The Agency for Cultural Affairs classifies the building as a hospitality facility, with a six-mat room and a bathroom alongside the principal room. It was made for tea, and also for keeping guests comfortably in place for a long stretch.
Why It Was Registered
The Tozanso Tea House became a Registered Tangible Cultural Property on August 1, 2016, as number 22-0227, under the criterion of being a model of design. That criterion applies to only three of the seven buildings here: this one, the detached wing and the annex.
The building covers 83 square meters beneath a tiled roof. Its interest lies in the way teahouse practice supports a structure that shows the rough framing of a country house indoors, which says something about how far a tea space in a prewar villa could depart from convention. Timbers now difficult to source add to the case for careful preservation.
Two Hearths, One Room
The principal room is known as the daironoma, the room of the large hearth. A dairo is cut wider than the standard hearth and used in the cold months. According to the preservation society, the room holds two hearths: one in the position used for a four-and-a-half-mat layout, and a large hearth set in the reversed orientation. That means two different ways of preparing tea within one space. The room is given as ten mats.
Look up and the beam frame is roughly worked and fully exposed. The ceiling is packed with round bamboo laid tight against itself, an effect closer to the loft of a farmhouse than to a formal parlor. Against that roughness sit generously scaled alcove fittings, so plainness and formality hold each other in balance. The posts, as in the detached wing, use logs of several species.
A veranda wraps the reception room on the east side. Because the building stands above the main house, standing on that veranda brings the whole estate and Sagami Bay into view at once. It explains why the tea house was put on the upper side of the garden rather than tucked behind the residence.
The extension of about 1975 was added by the Church of World Messianity after Okada Mokichi's death. Original room and later addition standing side by side is itself part of what the Tozanso Tea House records.
Visiting
Seeing the Tozanso Tea House means joining the guided round of the estate, which the preservation society operates on a reservation basis. Opening days are Sundays: usually the third of the month, but the fourth in March, May, August and November. Neither July nor December has one in 2026.
Two groups set out each opening day, one at 11:00 a.m. and one at 1:30 p.m., with a ceiling of ten people apiece. The charge of 1,000 yen is collected on arrival, and the circuit takes roughly an hour with a guide. To reserve, write to the society giving your name, a contact address, the date and time you want, and how many are coming; places go to the earliest messages.
Two things the published material leaves open are whether the room can be hired for a tea gathering and what the rules on cameras are. Both belong on the list of questions for the guide.
Walking from JR Atami Station takes some ten minutes to the southeast, climbing most of the way. Cars cannot be left within the grounds, which leaves the paid car parks in town. Because this building sits a level above the residence, a flight of steps leads up to it.
