The campaign runs from Thursday, May 14, 2026, to Wednesday, May 20, 2026. A total of 100 winners will be selected by lottery to receive a 500-yen dining coupon for the Yakitateno Karubi app. Winners will be chosen through a strict lottery process and notified via direct message from the official X account about one week after the campaign ends, together with a form for entering delivery information.

Coupons are scheduled to be distributed around early June 2026 through the official Yakitateno Karubi app. Yakitateno Karubi specializes in freshly grilled karubi rice bowls made with aged beef and yukgaejang soup featuring the rich umami of carefully selected beef. Its signature freshly grilled karubi rice bowl uses fresh karubi sliced daily in-store and grilled over high heat after each order, bringing out the natural flavor and aroma of the meat. The sauce blends 20 seasonings in a secret ratio to achieve a balanced mix of sweetness, heat, and acidity, while the rice is made with 100% Japanese-grown rice. Another signature item, yukgaejang soup, is cooked individually in small pots in-store. A special broth based on carefully selected beef is deepened with spicy Korean blended miso and gochujang, creating a soup in which the beef umami spreads immediately on the palate. In addition to dine-in service, the chain offers takeout, delivery services, and drive-throug
