Marukin Soy Sauce Historical Museum
Marukin Soy Sauce Historical Museum information
Lonely Planet review
Shōdo-shima was famous for its soy beans long before olives arrived, and several old soy-sauce companies are still in business here (as frequent whiffs around the island will remind you). Marukin has a small museum with displays of the sauce-making process, old implements, photos, and interesting facts you never knew about the ubiquitous brown stuff. There are good English explanations, and you can try the surprisingly tasty soy-sauce-flavoured ice cream. It's on the main road between Kusakabe and Sakate.
