Mikurigaike Onsen: Hot Spring Guide & Visitor Access

Springing on the Murodo plateau of Tateyama at about 2,400 meters, Mikurigaike Onsen is known as the highest-elevation hot spring inn in Japan. Its sulfur water, drawn from Jigokudani, and the sweeping view of the great Tateyama peaks before it blow away the fatigue of climbers.

Highlights

The clear blue Mikurigaike pond spreads just beside the inn, and the sight of the Tateyama range mirrored on its surface is a spectacle in itself. From the bath you can savor the crisp alpine air and the ridgelines, and at night a sky full of stars awaits. The simple sulfur spring piped from Jigokudani flows free, and its acidic, gentle water warms a body tired from alpine walking. The milk-tinged feel unique to a sulfur spring is a charm found only at this height.

Enjoying the Seasons

From early summer after the snowmelt, alpine flowers bloom in profusion, and in autumn the grassy slopes turn to russet color. The inn generally operates from mid-April through late November, closing in winter, so confirm the timing of your visit. Even in summer it is cool enough to chill morning and evening, and it is known as a place to escape the heat.

Access and Basic Information

Ascend to Murodo via the Tateyama Kurobe Alpine Route, then walk about fifteen minutes along the stone-paved footpath from Murodo Station. There are stone steps and mountain sections along the way. Both overnight stays and day-use bathing are possible, and it is cherished as a base for alpine hiking. Private cars cannot enter the area, so you connect between the vehicles of the Alpine Route to get there.

Practical Travel Notes

Access to Murodo depends entirely on the Alpine Route operating hours, so always confirm the first and last departures. At this high elevation the temperature is far lower than on the plains, and a jacket is indispensable even in midsummer. Take care with sudden weather changes and strong sun and ultraviolet rays. The footpath circling Mikurigaike pond and the Jigokudani overlook gather other sights within walking distance beyond the bath. For a day visit, plan your route working backward from the departure time of your descent. As this is around 2,400 meters, walking slowly to let your body adjust to the altitude keeps you comfortable.

A Quick Tip

At this high elevation the weather changes quickly, so warm clothing and sturdy shoes are essential. Plan around the operating hours of the Alpine Route and move with time to spare. Since it is easy to feel unwell at altitude, enjoying it without overdoing things and taking frequent rests is recommended.
