Mt. Jimbasan is actually located on the border of Tokyo metropolis and Kanagawa prefecture. The top of the mountain is one of the popular hiking spots near Tokyo. Several years ago, Mt. Takao, which is located near this mountain, was selected as one of the good sightseeing spots in the Michelin guide, so the the numbers of the hikers are increasing in recent years. Many Yama-girls (Mountain-hiking girls dressed with contemporary sports-fashion) are also visiting here recently. You can see people operating amature radio, the statue of a white horse, and some shops.
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.
