Okuikaiseido

We specialize in premium kelp, centered around Rishiri kelp, widely regarded as the finest. These kelps are aged in our dedicated, strictly controlled kelp storage facility, where they mature into ‘Kura-gakoi Kombu’ with enhanced umami. This tradition yields a meticulously refined flavor, earning the support of Michelin three-star and two-star restaurants, primarily in Tokyo and Kyoto.
