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.

    I saw from the back milling around Observatory. But obscured by trees will be. I would like to see because it never seen the Lake Mashu's mist. I could change the time because it is not easy to change the weather.

    Lake Mashu's mist and simply, but unfortunately nothing I cannot see who went to see the weather forecast is good. See milling around blue, on the occasion of the next reserve.

    We saw great Lake views. It is thanks to God really showed me the beautiful scenery. Thinking in shades of the Lake "and you!" and voices to put it out now.

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.
