Suntory Beverage & Food Ltd. will launch 'yappy', a wellness carbonated drink infused with highly fermentable dietary fiber (partially hydrolyzed guar gum), on June 29, 2026 (Mon), exclusively through the Suntory Food Online Store. 'yappy' is a new brand designed to support young people's passion for the things they love, with great taste, quality ingredients, and a bright, uplifting brand world. ■ Background In recent years, carbonated beverages enriched with dietary fiber have seen explosive growth in the U.S., creating a new category known as 'prebiotic sodas'※1. Amid rising global interest in dietary fiber as the next essential nutrient after protein※2, Japan's Ministry of Health, Labour and Welfare also recommends its consumption in the 'Dietary Reference Intakes for Japanese (2025 edition)'※3. Alongside this trend, especially among younger generations in Japan, there is a growing desire to smoothly transition from 'on' to 'off' mode in daily life and enjoy personal time in a comfortable way※4. While carbonated drinks are often chosen for such refreshing moments, some consumers still feel guilty due to concerns about sugar and calories. We believe there is strong demand in the Japanese market for a guilt-free, refreshing wellness soda. ※1 Source: CNBC, "Olipop prebiotic soda valued at $1.85 billion in funding round" (February 12, 2025) https://www.cnbc.com/2025/02/12/olipop-prebiotic-soda-valued-at-1point85-billion-in-funding-round.html ※2 Source: U.S. media magazine Better Homes & Gardens, "2026 Food Trends You’re About to See Everywhere" https://www.bhg.com/2026-food-trends-11856743 ※3 Source: Ministry of Health, Labour and Welfare, "Dietary Reference Intakes for Japanese (2025 edition)" Planning and Research Report ※4 Source: Mynavi, "Survey on Z Generation and 30s’ Switching Behavior" https://cm-marketinglab.mynavi.jp/column/research_switchonoff/ Human Holdings, "Survey on Z Generation’s Work Values and Authenticity 2025" https://www.athuman.com/news/2025/2
