15-million-year-old fossil seawater, beautifying hot springs, seasonal views, and fresh seafood and mountain delicacies.
A property located at the high-efficacy Itoigawa Onsen. Fossil seawater from 15 million years ago, emerging from the deep underground Fossa Magna, provides exceptional spring quality to moisturize the skin. From the guest rooms, enjoy the clear stream of the Himekawa River and seasonal views, and in the Japanese-style room on the top floor, relax while admiring the beautiful ridgeline. The restaurant offers fresh seafood from the Sea of Japan and mountain delicacies, with specialties including Nanban shrimp, Koshihikari rice, and Kubiki beef.
The open-air bath was a bit dark and felt slightly intimidating. (The environment might be influenced by the presence of bears.) Since it is outdoors, the water temperature could be slightly higher for better comfort.

Introduction of the Accommodation

Onsen property located by the Himekawa riverside
High-efficacy relaxing waters, Itoigawa Onsen. Its secret lies in the fossil seawater, 15 million years old, emerging from the Fossa Magna (meaning 'great trench') deep underground. Outside the guest room windows, the clear stream of the Himekawa River and seasonal landscapes unfold. Enjoy the diverse seasonal flavors of fresh seafood from the Sea of Japan, and mountain delicacies nurtured by nature and human hands, throughout the year.

Let's find jade!
Many of the stones found on the coast originate from the mountains of Itoigawa, traveling down rivers over many years before reaching the sea. The tributary "Kotakigawa" of "Himekawa," which can be seen from our Japanese-style rooms, contains jadeite stones. These jadeites flow from Kotakigawa to Himekawa and eventually reach the coast after a long journey, just like other stones. If you're lucky, you might discover some jade! ■ Itoigawa Coast (commonly known as Jade Coast) *10 minutes by car from our facility
