If you’ve ever been confused by all the Japanese names associated with “yellowtail” at sushi restaurants, you’re not alone. While researching this post I learned that my long-held belief that Kanpachi and Hamachi are two developmental stages of yellowtail was spectacularly wrong. As it turns out, Kanpachi, Hamachi and Yellowtail are three totally different fish! While tempting, I can’t blame American sushi restaurants for my miseducation. Even in Japan, many people seem to think that Kanpachi and Hamachi are just two names for the same fish. So why all the confusion?
