Kappa Sushi, operated by Kappa Create Co., Ltd. under the Colowide Group, will launch a collaboration campaign with the popular Korean character brand BRUNCH BROTHER. Starting Thursday, May 28, 2026, Kappa Sushi will hold an app-member-exclusive giveaway campaign at all Kappa Sushi locations, offering four types of original A5 notebooks. During the campaign, customers who spend 3,000 yen or more including tax on dine-in meals, including all-you-can-eat, or takeout orders, and present the barcode exchange coupon in the Kappa Sushi official app at checkout will receive a BRUNCH BROTHER original A5 notebook. One notebook will be given for every 3,000 yen spent including tax. Customers may choose from four designs, although design selection may not be available depending on stock. BRUNCH BROTHER is a Korean character brand known for delivering small moments of happiness, like taking a relaxing break with a cup of coffee during an ordinary day. The collaboration notebooks feature BRUNCH BROTHER’s gentle world combined with Kappa Sushi motifs such as tuna, tamago, parfaits, and premium pudding. The designs preserve the brand’s cafe-like, soothing atmosphere while adding Kappa Sushi’s sense of deliciousness and fun, making them suitable for everyday use, quick notes, or cafe time. Campaign details: The campaign begins on Thursday, May 28, 2026, and ends when supplies run out at each store. It will be available at all Kappa Sushi locations, excluding some stores under renovation. The four designs are A. Toast, B. Penguin, C. Duck, and D. Bunny & Puppy.
