Nihonbashi Dashiba will launch "Chumoppa-Style Katsuobushi Rice" on January 2, 2026, offering a creative fusion of Korean and Japanese flavors. The new menu item features premium hon-kare katsuobushi (aged bonito flakes) topped with Korean seaweed, takuan pickles, and finished with sesame oil and mayonnaise.
A Japanese Take on Korean Chumoppa
Katsuobushi rice is one of the signature dishes at Nihonbashi Dashiba Honten, with seasonal variations offered throughout the year. This latest creation draws inspiration from Chumoppa, the popular Korean mixed rice ball, adapting it with Nihonbashi Dashiba's signature ingredients. The dish centers around the rich umami of hon-kare katsuobushi, complemented by the distinctive flavor of Korean seaweed and the textural contrast of takuan. The addition of fragrant sesame oil and creamy mayonnaise creates a deeply satisfying and addictive flavor profile. For the best experience, mix all ingredients thoroughly before eating, just like traditional Chumoppa.

Developer's Commentary
The development team adapted the popular Korean home-style dish Chumoppa into katsuobushi rice, giving it a distinctive Nihonbashi Dashiba character. The foundation is the umami of hon-kare katsuobushi mixed with rice, elevated by mild and creamy mayonnaise that enhances the savory depth, the crisp texture of takuan, and the aromatic notes of sesame oil and Korean seaweed. Be sure to mix everything well, just like Chumoppa, to enjoy the perfect balance of hon-kare katsuobushi and toppings.
About Hon-Kare Katsuobushi
At Ninben, hon-kare katsuobushi refers to bonito that has undergone the mold cultivation and sun-drying process at least four times. Through repeated cycles of mold application and sun-drying over 4 to 6 months, hon-kare katsuobushi develops from ara-bushi to hadaka-bushi, resulting in a refined, less fishy aroma. This premium ingredient, commonly used in high-end restaurants, offers the elegant, mellow flavor and aroma unique to hon-kare katsuobushi.
