15-Day Limited Offer! All Items Served with 'Kinsei Akashari'! Plus, Recreating Traditional Edo-Period Sushi! Starting June 2nd (Tue) at Nigiri no Tokubei and Kaisen Atom

Atom Co., Ltd. (Headquarters: Yokohama, Kanagawa; President: Tsuyoshi Ueda), a member of the Colowide Group, will serve all sushi items with 'Akashari' (red vinegar rice) at its 'Nigiri no Tokubei' and 'Kaisen Atom' conveyor-belt sushi restaurants for a 15-day period from June 2 (Tue) to June 16 (Tue), 2026.

Our 'Kinsei Akashari' is a masterpiece developed by carefully selecting premium red vinegar. It uses 100% sake lees vinegar, blended with over 60% of Mizkan's exclusive 'Mitsuban Kamobi™' red vinegar. The sweet, floral aroma and deep richness of the red vinegar rice further enhance the flavor of the toppings.

Furthermore, using this 'Kinsei Akashari,' we will sell 'Ika no Inrozume' (stuffed squid), a recreation of traditional Edo-period sushi, born from our desire to let customers experience authentic Edo-style sushi. The squid is simmered in a sweet and spicy sauce and stuffed with vinegared rice mixed with pickled ginger and kanpyo, offering a delightful accent in color and texture.
