I know salmon is not a fish usually served at sushi-ya's in Tokyo because there is no salmon in the waters around the city. I do actually love salmon and was hoping that there are som good sushi-ya that might seve salmon even though there are no salmon caught around Tokyo. I am actually even more particular than that. What I am looking for is called a Keiji salmon or infant salmon. It is only caught at the end of November and has an unusally high fat content (20-30%). I wonder if this is served at any sushi-ya in Tokyo? I know they do in Hokkaido.
