Lake Mashu, Teshikaga-cho

Sometimes called the clearest lake in the world, Lake Mashu formed in the caldera of a potentially active stratovolcano, making it one of the most fertile and volatile areas in Japan. Surrounded by steep crater walls 200 m (660 ft) high, the transparent lake harbors an abundant diversity of life. During summer you might witness how the thick mist obscures its crystal surface, making the entire area even more mysterious. (A local legend even says that if you can see the surface of the lake during the mist, you'll have bad luck.) Many observation decks dot the area; visit all of them for that perfect photograph.

  • 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 ...  more »
  • It is a mysterious lake that is often fog by the cage of the air, and when we made our visit, it was a fine weather, the lake was blue and clear, very beautiful, just before the Golden Week, so few visitors, exceptionally quiet silence, well worth the visit.

  • Personally feel the lake of the United States more than bend ramp lake, calm and transparent lake water foil the volcanic lake of the mysterious Island. Visit the day more fortunate at a glance at the full picture of the lake, the face of the dark blue lake all commuting and worry about the fleeting. Recommended road East trip than one of the attractions

  • Transparency in the world until the early Showa 41 m was logged, and stocking of fish and crayfish and tourism road construction and air pollution by human hands after World War II is dramatically decreased to less than half transparency, is now 20 meters or less. I still keep in Japan. Seems to have been kept from these impurities hinder transparency without outflow of water from the river water here too, because of the low water temperature and depth of water minerals and nutrients, phytoplankton is extremely small, so unlikely. We also once had life, and still released fish, such as nutrition, not very inhabited only a few. World Heritage site's natural landscape is more touristy and that want to pollute.

  • So never seen Winter Lake is called tanchouzl and impress Kushiro after I visited. And quite a tour bus in the parking lot, the Observatory was quite crowded with tourists. I just learned from after over 5 years Buri completely, and over the surface of the Lake completely. The sight of sunny blue skies and freezing water water white, became a lucky day.

  • Because it is not easy to let people see the face of Toulouse Mountain, so called the mysterious Lake. In the September of 2013, just as the summer of Hokkaido turned autumn, we and a group of friends who loved Hokkaido came to the lake of yarn and wanted to see its true face, but it was not hidden in the cloud fog and kept its secret. The painting of the lake in fog can only be seen from postcards. 4 months later, in February 2014, we stood on its land again, the mystic Lake of lined, in the midst of a snow-white 零下12度, which was finally no longer draped in the face of the cloud fog yarn. The winter road, the sky is easier to clear, unless the wind snow, in general, see the lake, the machine is higher than the summer, want a nice, winter morning, is the mysterious lake is the most easily discovered when. Because the water gathered in the middle of the afternoon and formed a cloud fog surrounded the lake, interested friends, may wish to winter first to Sichuan soup or disciple bend to enjoy the comfortable temperature of the spring, the next morning, while the weather is stable when the mountain Zhou She is the best time. The winter of the lake of Moab, the first and third views of the left side and the lake on the right side of the Mo-week Outlook platform are open for visitors to watch, but the road to the third vision station and the MO-week Outlook platform will be closed due to snow and security factors. Want to see the color, only from disciple Ku area to view the first perspective, but the Winter Mountain area road easy to ice, and Bend road in winter slippery, pay more attention to the traffic information and attention to safety.

  • They say it's the most beautiful Lake of Japan, formed within a volcanic caldera, and who once had the distinction of Lake with the clearest waters in the world! At the Center is a small island that the Ainu called "island of gods" and all around there are trails that border it (although with the snow we couldn't cover them because closed), with two sights called belvedere 1 and 3. The Lake is definitely impressive, if you have possibility take a tour from May to October for hikers.
