Yuasa, town in Arida district, Wakayama prefecture, Japan
Yuasa is a small port town on the Kii Peninsula in Wakayama Prefecture, known for its traditional soy sauce production. It features narrow streets lined with wooden buildings and warehouses from the Edo period that overlook a quiet canal, creating a landscape shaped by centuries of trade.
Yuasa became a center for soy sauce production during the Edo period, with over 90 factories at its peak in the early 1800s. The town was designated a Preservation District for Historic Buildings by the Japanese government in 2006, protecting its architectural heritage and traditional crafts.
The name Yuasa reflects its past as a port town, and this identity shapes the town today. Residents work and live inside the old buildings, making history feel like a natural part of daily life rather than something frozen in time.
The town is easily reached by train, about an hour from Wakayama or Osaka, with the Touist Information Center near the station offering maps and local tips. Once there, walking is the best way to explore the narrow streets, and most shops and cafes are within easy reach, though many close on Wednesdays.
Yuasa is considered the birthplace of soy sauce in Japan, where a Buddhist monk brought fermentation techniques from China and these developed into the sauce we know today. Family businesses like Kadocho, founded in 1841, still use wild yeasts living in their houses and age barrels for four years to create their distinctive soy sauce.
