What Is the Former Otani Family Residence Ash Hut?
The Former Otani Family Residence Ash Hut (旧大谷家住宅灰小屋, Kyū Ōtani-ke Jūtaku Haigoya) is a single-story hut with storehouse-style fireproofing (Dozo-zukuri), built in 1935 in Mizuochi, Oyabe City, Toyama Prefecture, and was registered as a Registered Tangible Cultural Property (Building) on 26 March 2015. Its building area is only 1.4 m², and it was repaired in 2013.
It was built to collect the ash from the bathhouse that stands just to its south. The two date from the same year and work as a pair.
Why a 1.4 m² Hut Was Registered
The Former Otani Family Residence Ash Hut is roughly square, about 4 shaku (about 1.2 m) on each side, under a gabled (Kirizuma-zukuri) pantile roof (Sangawara-buki). The outer walls are boarded, with white Shikkui plaster on the upper part only.
The key feature is fire safety. The inner walls and floor are finished in earth plaster, so ash that might still hold live embers could be stored safely. That is why even a hut this small was built in storehouse fashion.
The Agency for Cultural Affairs presents it as a glimpse of traditional rural life. Heating the bath produced ash, and the ash had its own place: a routine chore turned into a building. It was registered for its contribution to the historic landscape.
The Board Door and the Ash Outlet
The interesting side of the Former Otani Family Residence Ash Hut is the north face. The upper part is a board door and the lower part is an opening for taking the ash out: in at the top, out at the bottom, the elevation simply follows the way it was used.
From outside you can see the two-tier wall, boards below and a band of white plaster above. The roof uses the same pantiles as the larger buildings, so Ōtani-ke Haigoya matches the rest of the estate.
Look at it together with the bathhouse to the south. Ash from the firebox only had to be carried a few steps, and the short gap between the two huts traces that daily path.
Visiting the Ash Hut
The Former Otani Family Residence Ash Hut stands in the museum grounds just north of the bathhouse, and admission lets you see it. It is too small to enter, so the visit is about the exterior.
To see the board door and ash outlet, walk around to the north side. The relationship with the bathhouse is clearest when you view both from the main house side.
