An inn with its own source on the Nadaura coast
Isopp is an onsen inn on the Nadaura coast of Himi, Toyama. It draws on its own Nadaura source and has open-air and indoor baths overlooking the Japan Sea. The source has been chosen for a national selection of 100 notable onsen, and the inn is loved as a place to enjoy a sea view and a salt spring together.
A salt spring at 56.8°C
The spring is a sodium-chloride water (isotonic, weakly alkaline, high-temperature) at 56.8°C at the source. Colourless and odourless, it is said to help with neuralgia and cold extremities and to warm the body thoroughly after bathing. Because the main bath alternates by day, staying overnight lets you enjoy both.
Visiting for the day
Day bathing is 11:00-17:00 with last entry at 16:00, at 700 yen for adults and 400 yen for children. It is normally open unless closed for works, but hours can be limited by group bookings, so calling 0766-74-2336 before setting out is advised. With its views over the Nadaura coast, it fits easily into a day along the Himi shoreline.
