The Shinetsu region generally refers to the mountainous inland area of central Honshu, primarily comprising Nagano and Niigata prefectures. "Shin" represents Nagano's old provincial name, Shinano, and "Etsu" represents Niigata's old name, Echigo. It is renowned for its majestic mountains (including parts of the Japan Alps), high-quality ski resorts, abundant hot springs, and beautiful rural scenery. Nagano Prefecture hosted the 1998 Winter Olympics and boasts numerous world-class ski resorts like Hakuba, Shiga Kogen, and Nozawa Onsen, attracting winter sports enthusiasts. Often called the "Roof of Japan," the prefecture is surrounded by mountains, offering excellent opportunities for hiking, trekking, and admiring alpine flora. Famous attractions include Zenko-ji Temple (an ancient Buddhist temple welcoming all sects), Matsumoto Castle (one of Japan's oldest surviving castles with a five-tiered, six-story keep, a National Treasure), and the Jigokudani Monkey Park (where unique snow monkeys can be seen bathing in hot springs). Niigata Prefecture faces the Sea of Japan and is famous for its high-quality rice (especially Koshihikari), sake (Japanese rice wine), and abundant seafood. It experiences heavy snowfall in winter, hosting popular ski areas like Naeba and Echigo-Yuzawa. Sado Island, belonging to the prefecture, was historically a gold mining site and possesses a distinct history and culture. Overall, the Shinetsu region presents magnificent natural landscapes, from snow-capped peaks to lush countryside, making it highly attractive and an ideal place to experience Japan's mountain culture, enjoy outdoor activities, and savor local sake and cuisine.
