A tour through this wonderful and mystical lake born from ancient volcanic activity. You will be guided deep into the serene forests - to places many people will normally never have a chance to visit.

Renowned for its strikingly beautiful blue color, Onneto is a small lake found amidst the forests, lakes, and volcanoes of Akan-Mashu National Park. The lake is surrounded in vast pure forests of Japanese Spruce, a species rarely found even in Hokkaido. This slow and steady hike explores the enchanting sights of this primeval forest, such as 300-year-old trees and entire fields of mosses and alpine plants.

This tour will not be offered on Fridays from June to September, but will be a "Onneto-Yunotaki Hike" tour for a limited time only.Please wait for a while until the reservation site goes live (scheduled to go live in mid-May 2022).
