The day I visited the fall, there are many tourists to see the frozen fall. Two days after, 85 % of the fall did freeze, which may be the highest rate in this year. You can see the rate(%) of the frozen data in the Hinohara tourist center web site, "hinohara-kankou.jp/keppyou.html". You can also see the web camera at "www.vill.hinohara.tokyo.jp/takilivecamera/small/cameraB.html", but only in the daytime.
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.
