The Handa Canal is located off the Kinuura Port. In the Edo period, this natural harbor was named “Koromogaura”. As this was a natural port, many large cago ships frequently visited.
The Brewing industry prospred in this time period and both “sake” and vineger were shipped to Edo (Tokyo) through the Handa Canal.
“Sake lees vinegar”, made from “sake lees” was first created and produced from this area, which became an essential ingredient for Edo style sushi.
