This is on a trail that leads to Mt. Usukiyama, one of the Tokura three mountains. The weatherforecast said that it was cloudy, but no rain in the daytime, but actually white mist covered the mountain area.
Tama area is the name of the western part of Tokyo Metropolis. It consists of 26 cities, 3 towns and a village. A lot of people (about 4 milion) live in a eastern half part of the area. However, there are many mountains in the western part of Tama area, and there are very little flat land. Many hiking spots are in the western area, so you can enjoy walking on the trail, camping, and so on. If you see the beautiful mountain scene, you may not believe this is also in Tokyo.
