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.

  • 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.

  • 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.

  • From the Observatory Roadless rider, which was the transparency of the world's largest in the past met in open Sun go down the road from a swim in the nude has become the world's second largest, and riders had to say. The Lake, called Lake Mashu's mist fifth ever done has never had. Show views of the very unlikely Japan will scale. Kussharo Lake visible from the observation deck. Photo on the left is the kussharo-Lake Mashu Lake Observatory.

  • Lake Mashu is Crater Lake in the town of Teshikaga, Hokkaidō. An area of 19.2 km2, circumference is about 20 km, the depth of the water level was 211.4 m. This is very high throughout the Lake, ranked No. 1 in the world. The Lake has a very different point than the other ordinary Lake, there is no river flows into the lake basin, also with no rivers that flow, the water level never varies, though there were stagnant. The Lake has a lot of fog covered around to the point that he calls "Kiri no Mashu-ko" (indoor fog coating), so can't see the panoramas. But when frosty melted away and the light blue color up surface is extremely beautiful, called "Mashu blue".  Because of the need to protect the environment, so people walk on the lake shore and within the Lake. So, can only see the Lake from one of the following: the first Observatory near hot springs Mashu, third Observatory near hot springs Kawayu Uramashu Observatory, from the town of Kiyosato.

  • The weather was good and great views. Lake Mashu's mist and said is understandable. Observatory more than 857 m above sea level, in September, went down, and the wind blows cold. Note a steep trail to the lookout, go by car.

Where to stay in Teshikaga-cho

The town of Teshikaga-cho itself has a good array of hotels, traditional ryokan, and a couple of more budget-friendly hostels. The more luxurious among them have onsite onsens and restaurants, and with proximity to the main train line, the area offers convenience for travelers just arriving or soon to leave. But the surrounding rural spots have just as much in terms of accommodations, particularly close to the lakes, with clusters of ryokans, some campgrounds, and luxury resorts.
