I Saw Bears, Sperm Whales, and Red-crowned Cranes in Some of Japan’s Most Beautiful National Parks

"I saw Lake Akan’s crystal-clear caldera waters reflecting mountains and forests, and learned it is uniquely home to mysterious marimo algae balls (designated a National Special Natural Monument); scientists study these marimo—only Lake Akan is now reported to host the large marimo nearly 5 inches in diameter—and their formation remains a captivating local mystery tied to water currents." - Kristen Pope

My only complaint from this place that there are too much to explore and too little time. Only have 3 hours to explore due to bus tour restrictions. It is so beautiful and magical. There is trekking path that provide some of the most stunning angle in this area. Look at the map from thw tourist center to find it. If possible stay there for at least 2 nights, totally worth it. If my stock rise by as much as 50% i will definitely visit Hokkaido again and stay at Lake Akan for 1 week. Thats how much i love this place. Though i recommend you to bring food from 7-eleven, most food in this area taste kinda bland

Great experience! A lake with some volcanic geological traces. We took a walk around part of the lake, it is really pleasant. Snow, sulphuric air, mud, frozen lake, and some snow blizzard, all combined to unforgettable experience.

Lake Akan is home to the Marimo Algae balls. I came here during mid of Dec. If you would like to escape from overwhelming tourist, come to Lake Akan. If early winter spend max 2 days here. i went to the Ainu village, shopped for souvenirs, had Ainu lunch, walked the trails to see bokke boiling mud and soaked in Onsen. During summer the trails to the mountains are opened and one can go for hikes. Or during winter when the lake is totally frozen, winter activities will be held on frozen Akanko.

A pretty lake where you can enjoy the lake view and walking along the hot spring street. Of course, the hot spring is totally worth it! In summer time, the sightseeing boat is available, and in winter time you may want to do fishing and ice activities.

We were here in June and the weather was perfect. Not seeing a lot of tourist this time around. We also took the cruise which took approximately an hour and you get to see the famous moss ball. A short trail near the lakeshore took you into the woods and a number of geothermal spots. Relax and enjoyable.

Lake Akan was a really buzzing place with a lot of snowmobiles circling around (looked like locals were competing in some sort of race). It’s pretty interesting place but you’ll have to walk around 5min to get to this sign, worth! Can’t wait to be back in summer where the sign is probably in the middle of the melted lake?

I went with my family in autumn, but the altitude was high and it was a little chilly, but the scenery was very beautiful. I feel that the shopping street is a little lonely.
