"One of the most scenic spot in Japan.Feature vast virgin forests of birch trees and Japanese larch trees." - Kamikochi.or
"Kamikochi is a small basin, 1,500 meters above sea level on the upper stream area of Azusa-gawa River, which runs through the western part of Nagano. The Hodaka Mountains, Yake-dake Mountains and Jonen Mountains surround Kamikochi. ... The whole area is covered with virgin forests of birches, Japanese larch trees and Japanese hemlocks. Taisho-ike Pond, Tashiro-ike Pond and Myojin-ike Pond are scattered in the forest and produce a beautiful landscape by reflecting the high-rising mountain peaks." - JNTO
We visited on a rainy day and hiked the loop trail from Kappa-Bashi to Myojin-Bashi and back.
