🍱 Kobumaki
In Hokkaido, which is one of the largest producers of kelp in Japan, "Kombu-maki" (kelp rolls), in which fish such as salmon and herring are rolled in kelp, has taken root. Kombu-rolls are often made with Hidaka kelp, which is soft and low in fiber content and is found in the Hidaka region. Today, kelp rolls are also made throughout Japan, and are often served at New Year's. Hokkaido accounts for 90% of the nation's kelp roll production. Hokkaido is Japan's leading kelp producer, accounting for 90% of the nation's total production. Kombu has a long history, and is even mentioned in the "Shoku Nihon Ki" (Records of Japan) in the 16th year of the Enryaku era (797). In the Kamakura period (1185-1333), trading ships began to carry kelp between the Matsumae area and Honshu, and in the Muromachi period (1333-1573), kelp was carried to Tsuruga in Echizen Province (present Fukui Prefecture) and then to Kyoto and Osaka. Later, as kelp fishing flourished during the Edo period (1603-1867), consumption of kelp increased, and it became a major transport item on the "Kitamae-bune," a Kansai route around the Sea of Japan. Kombu-maki" was made by combining kombu with herring, whose catches were high during the same period, and salmon, a specialty of Hokkaido, and became a local dish of Hokkaido.
