Noboribetsu Jigokudani: A crater ruins found near Lake Toya in Noboribetsu City, Hokkaido, Japan. Following a volcanic eruption, strange-shaped valleys made by lava, gray and brown rock formations, and a large amount of geothermal energy are blasted from the ground, resulting in a unique volcanic terrain landscape. There are over a dozen hot springs, each with its own unique features; some have hydrogen sulfide water quality, some have salt water quality, and some have iron. Jigokudani's Noboribetsu Hot Spring, in particular, is roughly 200 meters above sea level and is a hot spring resort surrounded by natural forests.
