Tokyo Unajiro Co., Ltd. (HQ: Shinjuku, Tokyo; Representative: Kazutoshi Yoshida) announced the return of the 'Unagiri Challenge 2026,' a competitive eating event featuring its signature 'Unagiri' (eel rice balls), to be held simultaneously at the Kagurazaka and Izumiotsu locations.

Known for their pop-up stalls at Ginza Mitsukoshi and a permanent shop at Tokyo Dome City LaQua, 'Unagiri' is the flagship product of the brand.

Following last year's success, the 'Unagiri Challenge' is back and expanding to a dual-city format.

Those who finish their challenge are eligible for a free entry fee.

Furthermore, any pieces left unfinished are individually wrapped and can be taken home.

This event is designed for competitive eaters, families, and friends to enjoy together.

Unagiri Challenge 2026

[Beginner] 30 pieces challenge Time limit: 30 minutes Fee: 12,000 yen (incl. tax) Reward: Entry fee waived

[Intermediate] 50 pieces challenge Time limit: 40 minutes Fee: 20,000 yen (incl. tax) Reward: Entry fee waived

[Final Trial] 100 pieces challenge Time limit: 90 minutes Fee: 40,000 yen (incl. tax) Reward: Entry fee waived

No Worries About Leftovers Since every 'Unagiri' is individually wrapped, leftovers can be taken home. Unlike typical food challenges, even those unsure of finishing can participate with peace of mind.

A Variety of Flavors The 30 and 50-piece challenges offer 3 types of Unagiri, while the 100-piece challenge features 6 types. A key feature is the ability to enjoy various flavors while competing.

Over 10kg in Total Weight Following a successful run last year, the event returns larger than ever. The final trial involves over 10kg of food. We invite competitive eaters, YouTubers, influencers, and media members nationwide to take part.
