A storehouse raised on stone against the river
The Hatcho Miso Head Office Storehouse (Historical Museum) (八丁味噌本社蔵（史料館）) is a two-level timber storehouse of 1907 in the Hatchō district of Okazaki, Aichi Prefecture, built in the plastered Dozo-zukuri manner and added to Japan's national register as a Registered Tangible Cultural Property in 1996. It belongs to Hatcho Miso Limited Partnership, a firm trading under the name Kakukyū that has made miso on this site since 1645.
The building sits on a tall plinth of piled stone and runs more than 30 meters from end to end. Both floors rise to full height, which is why the company has always called it the Ōgura, the great storehouse. The lower part of the wall is clad in dark boarding; above it the second level is finished in white lime plaster, and small grilled windows march along that white band at even intervals. The roof is tiled and the building area is 463 square meters.
The height of the plinth is not decoration. The Yahagi River runs close by, and when it flooded the water had to be kept out of the miso. Stone was piled high enough to lift the floor above it.
The Hatcho Miso Head Office Storehouse worked as a brewing store until 1941 and reopened as a museum in 1991. The ground floor held miso through its long maturation; the upper floor was where the soybean koji, the fermented starter that gives this miso its character, was cultivated.
Registered for its part in the landscape
The Hatcho Miso Head Office Storehouse (Historical Museum) was registered under the criterion for buildings that contribute to the historic landscape of the country. Its register number is 23-0002; the office building beside it, registered on the same day in 1996, is 23-0001. The two were the first properties in Aichi Prefecture to be listed as a Registered Tangible Cultural Property.
That criterion makes more sense once you look up the street rather than at the building alone. This corner of Hatchō is made of dark boarding and white plaster, one storehouse after another, and this one is the longest of them. The sheer quantity of wall it presents to the street is what gives the quarter its shape.
Its working history counts too. The storehouse brewed miso for 34 years from 1907 until 1941, and when that use ended it was neither gutted nor cleared away. Industrial buildings of this scale rarely survive the end of the process they were built for. This one did, in the Dozo-zukuri form it was given from the start.
Outside and inside reward different attention
From the yard, begin with the join between stone and timber. Roughly coursed blocks carry a wall of dark boarding that rises straight off them, and the horizontal line where the two meet makes the storehouse look lower and heavier than it is.
Then the grilled windows on the upper level, punched at regular intervals into the white plaster. They are small on purpose. A brewing store needed steady temperature and humidity more than it needed light.
Inside, the Hatcho Miso Head Office Storehouse is fitted out as a museum. Life-size figures work through the stages of the old process, from steaming the soybeans and forming them into balls to laying the mixture into the wooden vats. Among the exhibits are papers from 1901, when the company became a purveyor to the Imperial Household Ministry, along with packaging from successive decades and a corner of original letters and orders sent by well-known customers between the Meiji and Shōwa eras.
Three small monuments stand in front of the building. A stone Jizō figure said to have come out of the ground when an earlier storehouse was being built in the mid-Edo period; a stele of 1855 with the history of the Hayakawa family cut into its four faces; and a boundary marker of 1736 that once stood beside the Tōkaidō highway to show where the Okazaki domain began. The Jizō outdoors is a replica, and the original is kept in a case inside.
