The Sangokusan (960 m) is just located on the border of Yamanashi, Tokyo and Kanagawa prefectures, so the peak has been called Sangokusan (sangoku means three countries and san does a mountain). We can climb to this peak from the base, Gundari-shrine, by 75 min. walk. What a nice view!! But unfortunately, the day I took panorama, it was not superior condition, so we could not see Mt. Fuji. Please imagine the shape of the Mt. Fuji in your brain.
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.
