In reply to englishvoodoo1:
I don't know if you're looking for climbing info or just general Japan holiday info, but if the former, there's some stuff on my site... I don't update it very often as the backlog became a bit overwhelming, but feel free to take a look. Use the tabs on the right side to access posts about specific places/mountains/areas.

Have a great trip!
