Kappa Sushi Expands Its Onigiri Offerings

Kappa Sushi, part of the Colowide Group and based in Yokohama, is set to launch exciting new additions to its onigiri menu on July 2, 2026. The renowned conveyor-belt sushi chain will introduce two new flavors: Grilled Onigiri with Tuna and Grilled Onigiri with Seaweed.

Since the debut of Kappa’s grilled onigiri last year, consumers have shown overwhelming enthusiasm for these savory rice balls, which incorporate traditional sushi ingredients into a convenient and delightful snack. The new offerings include a classic flavor, seaweed, as well as a tuna variant that showcases the restaurant's expertise in crafting tuna dishes.

What’s Inside the New Onigiri?

The Grilled Onigiri with Tuna features a rich mix of red and fatty tuna, combined with a special mayonnaise and dashi soy sauce to enhance the flavor. This delicious mixture is generously placed on the sides and top of the grilled rice ball, offering a true taste of fine sushi, all wrapped in a handheld onigiri format.

On the other hand, the Grilled Onigiri with Seaweed utilizes Kappa Sushi's signature rice, which is brushed with a proprietary soy-based sauce and sesame oil, then grilled to perfection. Adding a delightful crunch to every bite, this onigiri is designed to be fluffy on the inside while maintaining a crispy exterior. The result is a satisfying and luxurious option for a light lunch or snack.

Takeout and Set Menus

In addition to individual onigiri offerings, Kappa Sushi is also rolling out convenient set meals ideal for quick lunches. These include:

• - Miso Soup Sets: Pair your grilled onigiri with miso soup, priced from 337 yen (tax included).
• - Takeaway Sets: Enjoy a combination of two seaweed onigiri, a grilled teriyaki hamburger, and dashi-maki egg, perfect for a busy day out or a picnic, starting at 362 yen (tax included).
