Located in Kirishima, Kagoshima, Kyushu, Japan, Kirishima Onsen Myoken is a unique thermal spring and spa. The water is bicarbonate-rich, a type of mineral-rich water. This area is exceptionally diverse due to its many active volcanoes, which create a variety of hot springs. Visitors can enjoy the natural beauty of this special location within a long thermal tradition associated with well-being.
Insider tip — Myoken Onsen in the Kirishima volcanic highlands of Kyushu draws iron-sulfurous water of deep reddish-brown color from vents in one of Japan's most active geothermal zones, where Sakurajima volcano smolders on the horizon. The Kirishima-Kinkowan National Park setting means bathing is accompanied by primeval cedar forests and mist-draped ridgelines. These waters are among the most mineral-dense in Kyushu and leave a visible orange tinge on towels and stone pool edges.
