Umenohana Group’s seafood izakayas in Tokyo are offering a free drink or one piece of recommended sushi on qualifying weekdays in September 2026. The weather-linked coupon campaign is available at Sakura Suisan, Teraken Honke, Uosama, and Uo ga Ichiban.
The key detail is that the temperature and rain conditions can be combined. On a day when the forecast reaches at least 33°C and the chance of rain is at least 50%, guests can receive both a free drink and one piece of recommended sushi.
The campaign applies at all stores of the four participating brands. Coupons are posted on each store’s Google Business Profile at 5:00 a.m. on the day of use, based on the Japan Meteorological Agency’s forecast. Guests must show the relevant coupon when ordering their first drink.
About the weather-linked izakaya campaign
The participating seafood izakayas focus on fresh seafood sent directly from Toyosu Market, carefully selected ingredients, and dishes prepared by skilled chefs. The campaign also reflects Teraken’s approach to using seafood efficiently, with different parts of each fish prepared in ways that suit them best
