Meaning
酒盗 (しゅとう, Shutō) is Shuto, a Japanese food (pickled salted or fermented, viscera).
What is Shuto?
Shutō is made by pickling the entrails of bonito ( katsuo ), fermenting them for more than six months, then chopping them up and sometimes adding a mixture of sake, honey, and mirin to them. There is also a tuna ( maguro ) type that has a milder character. The name of the dish means "sake thief" and is derived from the fact that it is a good side dish for sake. There are variations of shutō , such as hot pepper or green onions.
