A hot-spring bath outside the house
The Yusa Family Residence Bathhouse (遊佐家住宅外風呂, Yusa-ke Jūtaku Sotoburo) is a small hot-spring bathhouse attached to the east face of the main house on the Yusa farmstead in the Baba district of Naruko Onsen, Ōsaki City, Miyagi Prefecture, entered as a Registered Tangible Cultural Property on 11 December 1998.
Its date depends on which source you read. The Agency for Cultural Affairs gives around 1936, in the Showa era; Ōsaki City's list of registered properties gives around 1878, in the Meiji era. The gap is more than half a century, and published sources cannot settle it.
Sotoburo means a bath outside the main house, in its own building. This being Naruko Onsen, the Agency describes it as a facility using hot-spring water.
Why it was registered
The Yusa Family Residence Bathhouse was registered for its contribution to the historic landscape. The Agency's note calls it a plain, unpretentious building that is still used as a shared hot spring for the neighbourhood; that description dates from registration in 1998.
A private family bath that doubled as a communal bath for the surrounding households is a very specific piece of spa-town life, and this is the building that records it.
A concrete tub under an open roof
It is a small gabled Kirizuma-zukuri building entered from the long side, in the Hirairi manner, and roofed in sheet iron. A lean-to at the back served as a laundry, so the washing was done right behind the bath.
At the centre is a concrete tub with an area of 2.5 square metres and a depth of 0.6 metres. Around it are a washing area and a changing area, all under one simple timber shelter. There is no ceiling; the roof framing is left exposed, which also helps the steam escape.
Visiting and bathing
The Yusa Family Residence Bathhouse is on private property. It was a community bath at the time of registration, but there is no published information on how it is used today or whether visitors may bathe. It is not a public bathhouse for tourists, so please do not call at the house asking to use it.
Directions to the farmstead and the conditions that apply to the whole site are collected on the page for the farmstead as a group.
