Tokyo is the capital of Japan with the population of approximately 13 million. However, Tokyo contains a large mountainous area. The highest mountain, Mt. Kumotori is 2017 meters high. It is the source of water of Tama River. Tama River has formed gorge and valley along the upper stream. There is a Japanase painter's memorial art museum surrounded by Tama River valley's rich nature. In the museum, there is a wonderful dry landscape garden which is selected among top 20 lists of Japanese-style gardens by an American magazine. Around here, a light hiking along the river is enjoyable. Now, I recommend you experience a lot of nature in Tokyo. Why don't you join my tour?
