Japan

The Kobushi Biosphere Reserve encompasses most of the Kanto Mountains, including the main Okuchichibu ridge of 20 peaks rising above 2,000 metres. It is a watershed and source for major rivers, notably the Ara, Tama and Fuefuki rivers and Chikuma, or Shinano, River. The Biopshere Reserve features a wealth of geological formations and rock types with fauna that includes almost 40% of Japan recorded butterfly species, 24 of which are endangered. The area has traditionally been a centre for the cultivation of grapes, persimmons, peaches and other delicacies collectively described as the “eight rare fruits of Koshu.”
