Adjacent to the nearby Kawayu Eco-Center Museum is the Tsutsujigahara Trail that leads to the sulfurous Mt. Iwo, the source that heats the surrounding natural hot springs. As a result, the surrounding soil is high in acidity, thereby creating an alpine ecosystem that produces vegetation not typically found at areas of this elevation. On the way to the mountain you’ll pass Sakhalin Spruce Trees, wild rosemary, Labrador Tea Trees and a mix of deciduous and coniferous forests. You may also get a chance to see white-tailed Shika Deer (also referred to as Ezo Deer), foxes and a variety of birds. When you arrive at the mountain you might think you’ve left the planet for a moment or perhaps are visiting the set of the next Star Trek movie.

Labrador Tea covers the ground

The terrain takes a sudden change

Natural wonder or a set for the next Star Trek movie?

The activity never stops at Mt. Iwo

Water heats up and bubbles away
