Three functions under one roof
Behind the main house of the Hanada-Imai Family Residence, just west of the storehouse, stands a building that does three jobs at once. It combines a watermill hut, a miso storehouse and a shed, and it dates to the early Showa era, roughly the late 1920s.
The watermill hut sits toward the north of the west side, with the miso store to its south, and a shed built over the pair so that a single structure holds all three functions. The plan is practical rather than showy, shaped by the daily work of a large mountain farm.
Why this outbuilding matters
Watermills were once common in rural Japan, used to hull and grind grain, but very few survive in place. That this one remains, still part of the farmstead it served, makes the building an uncommon record of how such work was done.
Miso, a fermented soybean paste central to the Japanese kitchen, was often made and stored at home on a farm of this size, which is why a dedicated store sits alongside the mill. Registered as a Tangible Cultural Property in 2016, the building was recognised under the criterion for structures that would not be easy to recreate, a reflection of the vanished skills and habits it embodies.
What to look for
The interest lies in how the three uses are packed together and read as one. Seeing the watermill, the miso store and the shed sharing a single roof gives a clear sense of the range of tasks a large farm household handled on its own, from milling grain to fermenting and storing food.
The outbuilding stands within a private residence and is not generally open. Its form can be appreciated from the public lane behind the main house. Anyone hoping to see more should check with Gero City in advance.

Q&A
- What does this one building contain?
- A watermill hut, a miso storehouse and a shed, combined into a single structure with the shed built over the mill and the store.
- Why is a surviving watermill significant?
- Watermills were once widespread for hulling and grinding grain, but few remain in place. This one survives within the farmstead it served, which is unusual.
- What is miso, and why store it here?
- Miso is a fermented soybean paste basic to Japanese cooking. On a farm this size it was made and kept at home, so a dedicated store stands beside the mill.
- When was it built?
- In the early Showa era, roughly the late 1920s, with a renovation in 1980.
- Can I visit the interior?
- No. It stands within a private home and is not generally open. The exterior can be seen from the public lane. Please check with Gero City.
