What the Tea Room Is
The Iwane Family Residence Tea Room (岩根家住宅茶室, Iwane-ke Jūtaku Chashitsu) in Gokenya 2-chome, Tondabayashi City, Osaka Prefecture, is a tiny single-storey Chashitsu built around 1957 and registered as a Tangible Cultural Property on November 17, 2015. Its building area is just 3.1 square meters.
It bears the name Chisokutei, roughly the pavilion of knowing contentment. It stands in the inner courtyard south of the sake brewery, and it is made from one of the brewery's great sake barrels.
Of the eight registered structures at the Iwane Family Residence, the tea room is the youngest.
A Barrel Turned Tea Room
According to the Agency for Cultural Affairs, the body of the Iwane Family Residence Tea Room is a sake barrel about 2 meters across and 2 meters high. Log rafters radiate from the center over the top to carry a conical roof.
Inside there is an alcove for a hanging scroll, and opposite it the low crawl-in entrance that every tea room has. A round window is cut into the side wall. All the essentials of a tea room fit inside a circle 2 meters wide.
The Agency calls it an unusual brewer's tea room, made by fitting out the inside of a sake barrel. A family that made sake took a piece of brewing equipment and turned it into a place for tea. That idea, and the rarity of the form, is why a building of the late 1950s made the register. It is register no. 27-0639, registered under the historic landscape criterion.
What the Roof Is Made Of
The Agency's database gives two different roofing materials for the Iwane Family Residence Tea Room. The structure field says cedar bark (Sugikawabuki), while the written description says cypress bark (Hiwadabuki). Both are bark roofs laid in layers, but the materials differ.
This article reports both entries. The roof cannot be checked on site.
Seeing the Tea Room
The Iwane Family Residence Tea Room stands in the inner courtyard south of the brewery, inside the grounds, and cannot be seen from the public road. It is not open to visitors.
