Things to do in Japan in October

October closes 2 things below; the rest run as normal.

  • Closed
    Climbing Mount Fuji

    climbing above the 5th stations outside the official season is prohibited by law - the trails are unmaintained, the huts shut, and the mountain carries snow and ice

  • Closed
    Skiing in Hokkaido

    Hokkaido's summers are cool and dry rather than hot and humid, which is a different reason to go and not a skiing one
