This unique soy sauce museum will let you see how soy sauce is made and even smell soy sauce at different stages of fermentation, as it ages for a year. You must also try their delicious soy sauce ice-cream, which is very popular with both locals and tourists. It has a slight tint of soy sauce and it tastes like salted caramel.
Soy Sauce Kingdom was setup in 2006 to educate the public about the making of soy sauce, and you can have a hands-on experience to make your own unrefined soy sauce as well (booking required). But even if you just drop by, there are still plenty of things to explore like going into the actual wooden barrel used to make soy sauce, as well as seeing and smelling the soy sauce at different stages of fermentation. There is a cafe upstairs with a beautiful view, as it overlooks the fields outside. They sell food featuring soy sauce, such as onigiri (rice ball), egg-on-rice meal set, and dessert such as soy sauce pudding and dango (chewy sweet dumpling). You must also try their soy sauce ice-cream, which is very tasty and sells for ¥300.
Downstairs is where they have a shop that sells anything related to soy sauce and their own house brand of soy sauce too. There are soy sauce bread, soy sauce chocolate rusk, soy sauce dorayaki (a kind of Japanese pancake) and even soy sauce cakes. They also have a corner for you to taste various soy sauces and they teach you which kind pairs well with different foods.
Take the Tobu Line from Ikebukuro, around 1.5 hours, to Nishioya Station. Another station nearby is Komagawa Station, but both will make you to walk for 25-30 minutes, so the best is if you drive down.
