FamilyMart and Bongo launch new large onigiri series

FamilyMart is expanding its collaboration with the rice ball specialty shop Bongo by launching a new product, the ‘Large Onigiri: Tuna, Takuan, and Egg Yolk Soy Sauce,’ on October 6, 2026. This new addition follows the success of the Bongo-supervised series, which has surpassed 20 million cumulative sales since its introduction in March 2025.

The new onigiri features a redesigned tuna patty combined with an egg yolk soy sauce inspired by Bongo’s popular egg yolk soy sauce marinade. To prevent the flavors from becoming too indistinct, pickled radish (takuan) was added to provide texture and balance the richness of the tuna and egg yolk. The product is priced at 321 yen.

In a separate food industry development, Arigato Farm in Okayama City is launching a new dessert brand, ‘Arigato Anko,’ with its ‘An Milk’ product scheduled for release on October 8, 2026. The product is a two-layer fresh yokan made with domestic white bean paste and Hiruzen Jersey milk, available in five flavors. A public tasting event is scheduled for October 5 at the Omotecho Shopping District.
