🍱 Kobujime
Kobujime, which is made by sandwiching fresh sashimi with kombu, was created during the Edo period by combining Hokkaido kombu brought by Kitamaebune with fish caught in Toyama Bay. Kombu absorbs excess water from the fish and makes it last longer, so it was a way to preserve raw fish in those days when there were no refrigerators, but the flavor of the fish soaked in with the umami of kombu becomes richer and the flesh ages, giving it just the right amount of elasticity, thereby making it more delicious. Most of the kombu used for cooking in Toyama Prefecture, including kobujime, is Rausu kombu from Hokkaido. It is said that one of the reasons for this is that during the Meiji period, many of the citizens of Toyama Prefecture who moved to Hokkaido for development purposes lived in the Rausu region, and there they sent Rausu kelp, a specialty of the town, to their relatives in Toyama. The standard fish used for kobujime is swordfish, which Toyama residents call “sasu,” but other white fish such as sea bream and flounder, as well as Toyama's specialties, white shrimp and firefly squid, are also used. White shrimp kobujime is also a hometown-certified food selected by the prefecture.
