A kura is not only a building for storing things. Odazuki in Kitakata is a country market town of shop-kura and brewing-kura, and the miso, soy sauce and sake houses along it are working businesses rather than exhibits. A misegura is a storehouse used as a shop: the part facing the street is fitted out as a sales floor, so what a visitor sees is a row of warehouses trading as retailers, which looks odd for about a minute and then stops looking odd at all.

The brewing houses use the same construction for a different property. Thick walls hold an interior temperature steady, which turns the severity of a snow-country winter into a working condition rather than an obstacle, and fermentation is one of the few processes that benefits from a building being slow to change. Odazuki was designated an Important Preservation District in August 2018, and from the street you can also see kura walls built in brick. This is one corner of a city of about forty thousand; Aizu-Wakamatsu is roughly forty minutes away by car, and the snow gets deep.

Towns with a great many storehouses have generally suffered both fire and cold. A thick wall protects what is inside from flame, and the same thickness slows the passage of heat, so a single construction answers two entirely separate requirements — storage and brewing — without modification. That is why Kitakata is built the way it is, and why the kura here outnumber what the town's size would predict. One solution happened to fit two unrelated problems, and a town will always build more of the thing that does double duty.
