Yuasa, Wakayama

The smell arrives before the buildings do — something deep, fermented, almost sweet, carried on the sea air as you walk from Yuasa Station into the old town. This is Yuasa, on the Kii Peninsula's western coast, where the production of soy sauce has continued without interruption across centuries. The streets of the Preservation District hold working buildings, not museum pieces: darkened timber facades, narrow passages between storehouses, and the quiet industry of people who still do things by hand.

Kadocho, founded in the early nineteenth century, continues to brew Yuasa tamari shoyu using traditional methods, and a small resource room inside lets you read the process rather than just taste the result. Down the same lanes, Kobara Kyukichi Shoten operates under the Yamaji brand, producing saishikomi — a double-brewed soy sauce — in premises that trace back to the Koka era. The Jinburo building, a former public bathhouse from the Taisho period, now holds historical folk materials; its tiled interior still reads as a place where the neighborhood once gathered.

Yuasa's position at the inner reach of a ria coastline means the town also fishes: shirasu and shirauo appear at festivals like the Shirauo Matsuri, and the annual Saba to Aji Matsuri names its seafood plainly. The Kumano Kodo passes through the preservation district itself, not as a scenic detour but as a working route that the town grew around. Kinzanji miso, the paste whose liquid runoff is said to have given rise to soy sauce here, is still made and sold. The fermentation continues.
