Tuna‑fair promo with vouchers
A weekday “Super Tuna Sushi Fair” promotion from 小僧寿し features tuna‑packed rolls plus a giveaway of 2,000‑yen meal vouchers for 10 winners — a neat example of local dining promotions driving engagement. (The chain’s social promo pulled in hundreds of likes and thousands of reposts, underlining how targeted offers can bring people back during weekdays.) (x.com)
A takeout sushi chain in Japan tried to fill the slowest part of the week with one thing people already know how to buy fast: tuna. Kozosushi started a weekday-only “Super Tuna Sushi Fair” on April 6, 2026, running April 6-10 and April 13-17. (kozosushi.co.jp) The offer was built around two fixed-price boxes instead of a broad menu. “Super Tuna Sushi” was priced at 1,350 yen with tax, and “Super Fatty Tuna Sushi” was priced at 1,609 yen with tax. (prtimes.jp) The cheaper box was not a sampler with one or two tuna pieces tucked in. Kozosushi said it packed in 8 pieces of tuna nigiri, 6 pieces of minced-tuna gunkan, and 1 full tuna roll. (prtimes.jp) The pricier box added southern bluefin medium-fatty tuna cut in-store, which is the richer part of the fish with more marbling. Kozosushi described that box as centered on “minami maguro chutoro,” the cut Japanese chains use when they want a step-up item without going all the way to the most expensive belly meat. (prtimes.jp) The timing was narrow on purpose. The company limited the fair to weekdays, while its April calendar also showed separate weekend promotions on April 4-5, April 11-12, and April 18-19, which means it was using different hooks for different traffic patterns. (kozosushi.co.jp) Kozosushi tied the food offer to a social media giveaway at the same time. Its official site embedded posts from April 6 and April 8 promising 2,000-yen meal vouchers for 10 winners through a follow-and-repost campaign. (kozosushi.co.jp) Those posts drew visible engagement in the low-thousands, not just a handful of replies. The official site snapshot showed one April 8 post at 2,558 reposts and 978 likes, and one April 6 post at 2,727 reposts and 962 likes. (kozosushi.co.jp) This is the kind of promotion that fits Kozosushi’s business model. The chain is a takeout sushi operator under KOZO Holdings, and the April 3 release said the fair would run at Kozosushi stores, with some locations excluded and some prices varying by region. (prtimes.jp) The company also made the urgency very plain in the fine print. Each store could end sales once prepared quantities ran out, which turns a weekday lunch-or-dinner decision into something closer to a limited bakery batch than a standing menu item. (prtimes.jp) By April 10, 2026, the fair was already in its first week and had one more weekday block left on April 13-17. For a chain selling takeout, that is a simple play: one familiar fish, two easy price points, and a voucher giveaway big enough to make people repost before dinner. (kozosushi.co.jp; prtimes.jp)
