Shiobara Onsen, Masudaya Inn with Private Hot Spring and Scenic Open-Air Bath (Bungou no Yado Kai)

Tochigi Prefecture/Nasu-Shiobara

Enjoy the natural hot spring water from the ryokan's private source, flowing continuously from check-in throughout the night!

Our pride, the natural Onsen with free-flowing hot spring water, features two observation indoor baths on the 7th floor and three private open-air baths (available for a fee) on the 6th floor. Exclusive to our facility, the Masudaya Onsen boasts an abundant flow of 68 liters per minute, with a natural spring temperature of 68°C, offering a high-temperature Onsen known for its skin-beautifying properties and long-lasting warmth. Our dedicated staff ensures that you can enjoy the free-flowing Onsen anytime from check-in until 9:00 AM. Additionally, from 11:00 PM to 6:00 AM, the observation indoor baths are available for private use with a lock system, allowing you to enjoy the Onsen in complete privacy. Responding to guests' requests for private Onsen experiences, we have introduced the "Onsen Private Day," where you can enjoy not only the two observation indoor baths but also the usually fee-based private open-air baths for free and as many times as you like, creating a small Onsen tour experience. Why not indulge in a private open-air bath while gazing at the seasonal beauty of the Shiobara mountains, which change from morning to night? For meals, we offer a selection of local delicacies in small portions. Before check-out, don't miss the chance to savor our unique Onsen coffee, drip-brewed using the drinkable Masudaya Onsen water! Relax and unwind in the soothing sounds of the Houkigawa River, which flows right in front of our facility, while enjoying the Onsen. Our staff is dedicated to providing an extraordinary experience and looks forward to welcoming you.
