FREEOnneto Hot Falls
Onneto · Hokkaido
A geothermal waterfall in Akan Mashu National Park in eastern Hokkaido, within the UNESCO-listed Shiretoko wilderness. The waterfall itself is not a bathing spring: since 1989, entering the water has been prohibited to protect unique manganese-producing microorganisms that form rare black mineral deposits on the rock surfaces. The falls are a viewing destination, reached by a 20-minute forest walk.
