Sun Hatoya

Sun Hatoya (ホテルサンハトヤ) is a high-rise resort hotel located along the coast in Ito, Shizuoka Prefecture, Japan. It opened on April 1, 1975, as the sister hotel of the long-established Hatoya Hotel, founded by the third-generation owner of the Hatoya family business. The hotel is operated by Fuji Shoji Co., Ltd., the same company that runs Hatoya Hotel. Sun Hatoya is known for its distinctive white 15-story building, four see-through elevators, and a large rooftop sign reading "Sun Hatoya." All guest rooms are designed to offer ocean views. The hotel features a unique undersea hot spring called "Sengoku-buro," where bathers can enjoy a hot spring bath while watching fish swim in a large aquarium next to the tub, creating a "Palace of the Dragon King" atmosphere. Dining is offered in a restaurant theater where guests can enjoy dinner shows, a feature not present at the original Hatoya Hotel. Adjacent to the hotel is Hatoya Tairyoen, a day-use hot spring and restaurant facility that includes the undersea hot spring, an indoor and outdoor swimsuit zone, and a naked zone. The hotel also has a fishing pond that operates seasonally, with a unique "three-stage reverse slide" pricing system where the more fish you catch, the cheaper each fish becomes. Sun Hatoya was heavily promoted through television commercials in the Kanto, Chukyo, and Kansai regions until the late 1980s, featuring the famous jingle "If you go to Ito, it's Hatoya, the phone number is Yoifuro (4126)." The hotel remains a popular destination for hot spring resorts in the Ito area.

Sun Hatoya opened on April 1, 1975, as a sister hotel to the existing Hatoya Hotel in Ito, Shizuoka. It was established by the third-generation owner of the Hatoya family business, which also operates Hatoya Hotel under Fuji Shoji Co., Ltd. The hotel was built as a white 15-story high-rise on the coast of Yumoto, Ito, and quickly became a landmark with its rooftop sign and see-through elevators. The opening was promoted with the catchphrase "Sun Hatoya opens gorgeously" and television commercials featuring celebrities such as Hiroshi Tamaki and Risako Katase. The hotel's undersea hot spring, Sengoku-buro, and the adjacent Hatoya Tairyoen day-use facility became popular attractions. In the 1980s, the hotel's TV commercials, including the famous "Hatoya" jingle and the "4126 exercise" song, were broadcast widely in the Kanto, Chukyo, and Kansai regions. The fishing pond at Hatoya Tairyoen introduced a unique "three-stage reverse slide" pricing system. Over the years, the hotel has undergone renovations, including the 2008 renewal of the day-use undersea hot spring and the 2023 renovation of the restaurant. The fishing pond was suspended year-round after the COVID-19 pandemic. Sun Hatoya continues to operate as a resort hotel, maintaining its retro Showa-era charm.
