Lake Mashu

4.5 (200)Natural FeatureEstablishment

Lake Mashu, located in Akan Mashu National Park, Hokkaido, is an enchanting caldera lake renowned for its astonishing clarity and serene beauty. Often cloaked in mist, this secluded lake is ranked among the clearest in the world, with visibility sometimes exceeding 40 meters, making it a marvel of natural purity.

The lake's isolation contributes to its untouched allure. While direct access to the lake's shores is restricted to preserve its pristine condition, strategically placed observation decks provide visitors with stunning panoramic views. These vantage points offer a chance to witness Lake Mashu's deep blue waters and the dramatic cliffs that encircle it, creating a mesmerizing and almost otherworldly landscape.

Lake Mashu's mystical vibe is enhanced by its reputation in local folklore as a sacred place shrouded in mystery and legend. Its unpredictable weather, with sudden mists that can envelop the lake in seconds, adds to its enigmatic charm, captivating the imagination of all who visit.

What other travelers are saying about Lake Mashu

On 2 Sept 2024, my wife and I drove up here. We weren’t sure if we were here before. Anyhow, we stayed long and bought some souvenirs. I had a loss and find - I dropped a pudding near a seat!
Recommend observation deck 3. Somehow google recommends deck 1 as the best but for me deck 3 was def better. Video 1 is of deck 3 and you get a beautiful angle of the lake. Didn’t bother taking videos for deck 1 except for the fox that was roaming around 🤣 Recommend trying the Blue ice cream (ramune flavoured) as well as the Yubari melon (1 for 600 yen)

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 is a bus which operates on a limited schedule from Mashu town but leaves late and returns early leaving very little time for anything more than visiting the observation deck. Definitely not for a long day hike. We didn’t have a car so ended up hitch hiking to and from the lake. Fortunately Japanese people are extremely nice and we easily got rides to and from Kawayu Onsen. We did the hike around the south portion of the lake to the Mt Kamui lookout point. An amazing hike with zero visibility on the way out but the clouds lifted for the return and we finally got to see how beautiful the lake is. Afterwards, we got to go back to our ryokan and relax away our pain. If you want any specific info on this hike, feel free to reach out to us. You can find our exact route by searching for Career Break Adventures and Lake Mashu, Japanese Hike or something similar. Good luck and enjoy!

摩周湖 Lake Mashu is beautiful in all seasons. Visited the place 3 times, and most impressive all of would be the wee morning viewing of unkai "雲海".
