Mercure Nagano Matsushiro Resort & Spa, an all-inclusive resort hotel with views of the Northern Alps and an ideal base for Shinshu sightseeing (Location: Nagano City, Nagano Prefecture / General Manager: Hiroshi Yamamoto), will hold a "Watermelon Sweets Fair" at its buffet restaurant "Locavore" starting July 1, 2026 (Wed). Nagano Prefecture is known as one of Japan's leading watermelon-producing regions, and watermelon is a beloved summer delicacy. We have prepared visually refreshing sweets such as roll cakes that showcase the color of watermelon and panna cotta with watermelon sauce, in the dessert corner of our dinner buffet. You can enjoy a dinner time unique to Shinshu in summer while savoring the fresh sweetness and refreshing aroma. Additionally, at the newly opened lounge "Waraunj" this spring, we are holding events where you can experience Nagano Matsushiro's unique culture and attractions, such as creating original shaved ice with 100% fresh fruit topping sauces and experiencing Sanada Bushi. Enjoy a leisurely Shinshu summer that can only be experienced here, with clear air, seasonal fruits, and the culture that breathes in this land.
