This is a very beautiful lake and makes for incredible hiking. We visited recently and added a day hike around this lake to the short hike past Mt Io. Getting to the lake is a little tricky if you are staying in Kawayu Onsen. There...More

Beautiful sightseeing from the top of the mountain. Great landscapes on both sides. The lake has a beautiful color. We made a lot of great pictures. But once you have reached the observatory, nothing else to do there, little bit disappointing...

I don’t recommend that. Better to stay over in Lake Mashu for a night before heading back to Abashiri.
