What is Kobumaki?

Kobumaki (昆布巻き) is a traditional Japanese dish wrapped fish, often herring, in kombu (kelp) and tying it with kanpyo (dried gourd strips) before simmering it in a savory, slightly sweet soy-based broth. The word “kobu” sounds similar toyorokobu , meaning “to rejoice” in Japanese, making kobumaki a symbol of happiness and joy. Locals traditionally made this with soft Hidaka kelp, known for its tender texture and low fiber content. Hidaka kelp, harvested from the Hidaka region of Hokkaido suited for kobumaki because it’s easy to wrap around fish or vegetables without becoming tough. While originally popular in specific regions, kobumaki has now become a common dish nationwide, especially as part of osechi ryori for New Year’s celebrations.

Kobumaki History

Kobumaki, a well-known Japanese dish of fish such as herring or salmon wrapped in kelp, has its roots in Hokkaido, one of Japan’s top kelp-producing regions. Hokkaido supplies nearly 90% of Japan’s kelp, with soft Hidaka kelp—low in fiber and harvested from the Hidaka region—favored for kobumaki. The history of kelp dates back to 797, mentioned in Shoku Nihongi. Trade routes introduced Hokkaido kelp to Honshu during the Kamakura period, expanding its distribution through Echizen Province to Kyoto and Osaka by the Muromachi period. The Edo period saw further growth in kelp fishing and trade along the Kitamae-bune route, with Hokkaido’s abundant herring and salmon inspiring the creation of kobumaki, which later became a staple in osechi ryori, Japan’s New Year’s feast.
