from "Lonely Planet Japan", Yakushima is
- a Unesco World heritage site
- one of the wettest places in Japan
- has the world-famous yakusugi (Cryptomeria japonica)
* I enjoyed a guide hiking tour by the following. http://www.yamazuki.jp/camp-tour/yakushima-jyuuou.html
Along with two other guests and the guide, I trekked the mountains in full two days.
We started from Arakawa trailhead (604m), stayed at Shin-takatsuka huts,
climbed at Miyanoura-dake, the highest point in southern Japan,
and finished the hike at Yodogawa trailhead (1370m).
This was one of the best hike in my life.
