This web site is written and managed by yamadarake. I started this web site to present all information about Japanese mountains which I collected for myself to climb them. Basically, all the information is collected from the Internet. The original web site is written in Japanese. So there is less information in English pages when compared to the original ones. But since I can speak English a little bit so I decided to provide the information also in English, as much as possible. I am very careful with the accuracy of the information I collected, however, please understand that the use of this site is at your own risk, and I do not guarantee anything on this web site.
