The “Korashō ♡ Chocolat Campaign,” a collaboration between Shinkenzemi’s Korashō and Meiji Milk Chocolate’s 100th anniversary, will be held at Lawson stores nationwide starting October 6, 2026. When you purchase three eligible Meiji snacks, you’ll receive one of four original puffy stickers—featuring a design of Korashō transformed into chocolate—on a first-come, first-served basis while supplies last.
