Mt. Jonen-dake

This mountain is very noticeable from the Azumino area when looking at the Northern Alps.  Many might feel that way.  The beautiful pyramidal shape of the mountain makes hikers long to climb it.  It is said that the origin of the name comes from the shape of the mountains which looks like “a monk is praying”.  When you look out for Mt. Kita-hodaka dake and Mt. Yari-gatake, the dignified shapes of the mountains might make you feel like paying your respects to them.  When Weston visited here, he was eager to listen to the story from the local folks.  The elevation does not reach 2,900 m, however, it is a noticeable shape from anywhere.  Therefore, the mountainous area that shapes the outer rim of the southern part of the Northern Japan Alps is named the Jyounen Mountains.  Any route to the summit of the mountain is quite tiring, which also makes you feel very accomplished when you stand at the summit.  The view from the summit is also phenomenal.
