Gurunavi has teamed up with Fujicco for a MUGEN-KONBU collaboration menu fair at 10 restaurants in Tokyo from October 14, 2026. The fair introduces dishes created with Fujicco’s smooth paste made from fresh kelp harvested in Hokkaido.
The fair runs through December 13, while a related customer campaign continues until December 20 at 11:59 p.m. Check the ¥3,000 minimum dining spend and other conditions before you go; the key details are listed below.
Each participating restaurant will develop its own dish using one or more of three flavors: Plain, Green Chili and Sansho Pepper, or Shiso Seed and Ginger. Diners can also buy a three-jar MUGEN-KONBU set for ¥2,700 (tax included), while selected guests can enter to win a ¥2,000 digital gourmet gift card.
About the MUGEN-KONBU Collaboration Fair
The fair pairs Gurunavi’s restaurant network with Fujicco’s MUGEN-KONBU product. The paste is made by blending early-harvest kelp from Hokkaido without drying it first, creating a smooth texture that brings out the kelp’s natural umami. It contains no added oils or food additives such as flavor enhancers, coloring agents, or thickeners.

The Plain flavor combines soy sauce and sugar for a simple taste with no added ingredients, while Green Chili and Sansho Pepper adds green chili, sansho pepper, and whole sansho berries for a crisp spicy note.
Shiso Seed and Ginger combines chopped ginger with small shiso seeds for a fresh flavor and light texture. The jars contain 100 grams each for the Green Chili and Sansho Pepper and Shiso Seed and Ginger flavors, and 105 grams for Plain. The product is priced at ¥2,700 (tax included) for three jars.
