Sushiro teams up with RSK Sanyo Broadcasting’s “Kinyo Live Imadoki!” for the first time

Akindo Sushiro Co., Ltd. (headquarters: Suita, Osaka; President: Kohei Arai) has partnered with the RSK Sanyo Broadcasting information program “Kinyo Live Imadoki!” for its first-ever collaboration. Three jointly developed items inspired by the local cuisine and specialties of Okayama and Kagawa are on sale from Friday, August 21, 2026 at Sushiro locations in Okayama and Kagawa prefectures. The strongly regional lineup makes these dishes something you can only enjoy in this part of Japan.

Born from the promise to “create restaurants loved by the community”

Sushiro upholds five promises, one of which is to “create restaurants loved by the community.” Wanting to give something back to customers in Okayama and Kagawa, the chain joined forces with the Friday evening information program broadcast across both prefectures. The three items were conceived by program announcers Mayu Sugisawa, Ryota Sakai and Kanon Hitotsubo, then reworked by Sushiro’s product development team so they could be served consistently in stores. Seeing announcers’ local favorites turned into conveyor-belt sushi plates is the highlight of this project.

The three collaboration items in detail

Olive Roll (from 280 yen incl. tax)

A creative sushi roll starring olives. Avocado and lettuce are rolled in-store, then topped with marinated octopus and shrimp plus olives, and finished with a house-made mayo-vinegar-soy dressing so it eats like a salad. Planned volume is 3,200 servings; sales end once sold out.

Demi Katsu Nigiri (from 200 yen incl. tax)

Inspired by “demi katsu don,” a specialty that originated in Okayama. Pork cutlet is fried in-store only after your order is placed, then paired with a special demi-glace sauce made using Sushiro’s sweet tare. The freshly fried texture and the aroma of the sweet sauce are irresistible. With a planned volume of 7,000 servings, the largest of the three, it is the star of the collaboration.

Okayama-Style Bara Sushi (from 280 yen incl. tax)

A Sushiro take on Okayama’s local dish “Okayama bara sushi.” Sushi rice, shredded egg crepe and fillings are layered, then topped colorfully with bite-sized conger eel, gizzard shad and shrimp along with cucumber, kanpyo and herring roe. The appeal is enjoying a festive dish in a casual single portion. Planned volume is 3,000 servings.
