Mt Myoko

Mt Myoko (Japanese: 妙高山) is one of the most striking hyakumeizan*, an active volcano whose bold, symmetrical shape dominates the landscape around the remote Tsubame Onsen in Niigata prefecture. Its summit is a lava dome sculpted by past eruptions, giving the mountain a rugged, rocky character that feels unmistakably volcanic. The area receives enormous snowfall each winter, so much that several ski resorts cluster around its base and the climbing season begins relatively late, often not until early summer, when the deep snowfields finally retreat.

 

The standard route from Tsubame Onsen is one of the most atmospheric approaches to any mountain in the region. The trail begins with narrow traverses above a deep valley, where steam vents hiss from active fumaroles and the smell of sulphur drifts across the path. Rivers and waterfalls run milky blue or rust‑colored, hinting at the volcanic minerals dissolved in the water.

 

The climb itself is steep and relentless. The trail rises sharply through forest and rocky gullies, eventually reaching a chain‑assisted section where hikers must negotiate a narrow, exposed rocky passage before gaining the summit plateau. It’s not technical, but it demands car, especially when the rock is wet or the weather unstable. From the summit, the views can be magnificent: Mt Hiuchi rising close by, the ridges of the Niigata mountains stretching north, and the Japan Sea shimmering faintly in the distance.

 

I’ve climbed Myoko several times, but the mountain has a habit of hiding behind clouds, perhaps a result of its proximity to the northern coastline, where weather systems roll in quickly from the sea. Even so, the climb is always rewarding, and on clear days the panorama is reportedly superb. For those with time and energy, the hike can be combined with a climb of Mt. Hiuchi, creating one of the finest two‑peak days in northern Nagano and Niigata.

 

Myoko is a mountain of steam, stone, and steep slopes. It’s never easy, always memorable.
