Soda katsuo (frigate and bullet tuna) is called mejika in Susaki and surrounding areas. The mejika that is less than one year-old is particularly called “shinko”. Because it loses its freshness easily, it is a rare fact in the country that the shinko is eaten in sashimi with a soy sauce that is mixed with pressed citrus juice (or bushukan, the official name is “mochiyu”). Because it tastes really tender and amazingly good, it is possible to eat the mejika in a short period of time between August and September. Eating the mejika sashimi is a summer custom in Susaki.
