Okamoto Soy Sauce Brewery is a soy sauce manufacturer based on the island of Osakikamijima. Utilizing the weather conditions on Osakikamijima that are fit for fermentation, this place has been producing basic, handmade soy sauce with enormous wooden tubs since time immemorial. If reservations are made in advance, it is possible to tour the production facilities where the fermentation and maturation processes of soybeans and wheat are carried out. The soy sauce and seasoning brewed here can be bought directly inside the store, so they are recommended as a souvenir of Osakikamijima.
Moment of Joy
At Okamoto Soy Sauce Brewery, one can bear witness to the manufacturing process of soy sauce in a traditional warehouse that has been going on since ancient times. The highlight of said process is probably the part where they turn the malt into fermented mash that will eventually be refined into soy sauce. Inside the warehouse, where the giant wooden tubs are lined up snugly and only a few adult humans can fit exactly between them, the sweet scent of soy sauce wafts in the surrounding air. After enjoying a tour of the factory, customers can then buy handmade soy sauce or miso at the store.
