Sasa-one, in which "sasa" and "o-ne" mean bamboo grass and a ridge, respectively, is a long ridge starting from the Mitohzan Mt. Some hikers like this ridge because peple can enjoy calm and cool walking on the trail. Many wild animals may live in this area, deers, boars, and bears(very dangerous). I saw four deers running in front of me just after taking this panorama!!Here about 1000m above sea level.
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.
