Nakano Family Residence Tea House

Koan: A Tea Room Built in 1951

The Tea House of the Nakano Family Residence (中野家住宅茶室, Nakano-ke Jutaku Chashitsu), known by the name Koan (皎庵, also written Kōan), is a mid-Showa tea room built in 1951 in the Choshi district of Nagaokakyo City, Kyoto Prefecture, and entered on the national register of Registered Tangible Cultural Properties (登録有形文化財) on 10 September 2010. It stands at the eastern edge of the Nakano plot, joined to the family storehouse, at the far end of the garden from the main house.

The building covers 31 square metres. It is single-storey timber construction with a partial upper floor, roofed in sangawara pantile over a combination of hipped-gable irimoya and gabled kirizuma forms. The tea room proper is four and a half mats. The Agency for Cultural Affairs record places the alcove and a low hira-shoin window in the western corner; the current operator describes the arrangement as a daime-doko alcove with a study window at its side. Either way, the geometry of that corner is where a guest's eye lands first.

Nothing about the exterior announces the year. A visitor could reasonably place it a century earlier. The date matters because 1951 was not a moment when many Japanese families were commissioning tea rooms, and because of who built it.

The Ninth Kitamura Denbei

The tea house was built during a general renovation of the Nakano estate carried out for the fifth son of Nakano Taneichiro and his wife. The carpenter was Kitamura Denbei in the ninth generation. The Kitamura house kept its premises on Kiyamachi-dori in Kyoto and passed the name Denbei down the line; from the fourth generation to the ninth, machiya carpentry was the family trade. The ninth Denbei is credited with more than a hundred townhouses in Kyoto alone.

The Agency for Cultural Affairs entry calls him a sukiya carpenter, a specialist in the refined residential and tea idiom; the operator's own account and the city's describe him as a master of machiya carpentry who was also accomplished in sukiya work. The two labels are not in conflict so much as describing a career from different angles. What the sources agree on is his method: he went out and measured tea rooms, across schools and lineages, rather than working from inherited pattern. A book he co-authored on tea architecture carried English alongside the Japanese, which in that period suggests he expected readers outside Japan.

Very few buildings by his hand survive. The tea house at Choshi is among them, which is a substantial part of why the registration was made.

The name Koan was bestowed by Sen Soshitsu, the fourteenth-generation head of the Urasenke school of tea, with the wish that it be a retreat where people of clear heart could meet one another.

A Ceiling Divided Into Four, With Light Built In

Look up. The ajiro ceiling, woven from split bamboo or thin wood, is split into four panels set at different heights: raised in front of the alcove, dropped over the kyujiguchi, the small serving entrance. Lighting is integrated into the arrangement.

Electric light in a tea room is not unheard of; it began appearing from the Taisho era. Dividing the ceiling into a stepped four-part grid to accommodate it is something else. Architects Nakata Satoshi and Nakata Takako, who handled the 2019 repairs, read the move as a departure from tea-room convention, and connect it to Denbei's friendship with Fujii Koji, the architect of Chochikukyo in neighbouring Oyamazaki. Fujii worked in straight lines and geometric division, and Chochikukyo is regarded internationally as a landmark of Japanese modernism. The link is the architects' reading rather than a documented statement by Denbei himself, and it is worth holding as an informed suggestion.

Denbei's drawings for the renovation survive, and they show what he was solving for. Two circulation routes are laid out with care: guests moving from the waiting bench through the garden to the tea room, and the host moving around the back to prepare at the mizuya. Colour coding in his documents separates additions from repairs, with photographs and elevations attached. It is an unusually complete record of a mid-century renovation of an Edo-period house.

Seeing the Tea House

The tea house is not part of the ordinary route through the property. Since August 2019 the Nakano Family Residence has operated as Nakanotei, a restaurant and coffee house run by the general incorporated association Kurashi Lamp, which employs people with disabilities; the city of Nagaokakyo has owned the buildings since the family donated them in 2014. Customers are received in the main house. Viewing the tea house is available for an additional 500 yen, and it is sensible to raise the request when booking rather than on arrival, since staff need to open the building.

Service runs 11:30 to 15:00 for lunch and cafe, with last orders at 14:00, and 18:00 to 22:00 for dinner, with last orders at 21:00. Sundays and Mondays are closed. Meals are taken by reservation. Photography inside is generally accepted, with the usual courtesy toward other guests. Hours, pricing and the tea house arrangement all sit with the operator and are subject to change, so confirm by telephone before making the trip.

The property is a six to nine minute walk from Nishiyama-Tennozan Station on the Hankyu Kyoto Line, following the old Saigoku Kaido northeast from the Choshi-Hakkaku intersection. Three free parking spaces sit in front, about five minutes from the Nagaokakyo interchange of the Kyoto Jukan Expressway.

Anyone who comes for the ceiling should book Chochikukyo in Oyamazaki as well, which also requires advance reservation. Seeing Fujii's 1928 house and this small 1951 room within a few hours of each other makes the argument about influence far better than any paragraph can.
