I believe right now only Dannavy will be able to give us some insight into Japando you have specific thoughts you wish to ask? I can tell you about climbing Mount Fuji for one. When it rains, it's like climbing cement mix but why the elderly can truck their way up so smoothly I have no idea.
We often get many images of a perfect mount Fuji however this is not so, Fuji has a gigantic divit sliced out of it (about 1,000 square foot of the mountain side) caused by the last major eruption in 1707 when the mountain did a lateral St Hellens. The one thing the tour guides always say before your climb is....
"We are advised to explain that Fuji-san is an active volcano and that we share no responsibility if he should become angry during your climb. Please run away from the sumit should any unfortunate occurances unfold."
How re-assuring.
