I'm planning to clinb Mt. Fuji in September 7th from Kawaguchiko trial but I've noticed that in September the last bus to 5th station is at 13.50h. (http://www.japan-guide.com/bus/fuji.html).

Do you know if there are more buses in the afternoon to climb the mountain during the night?

Other question: Do you know if the Kawaguchiko train station have boxes to store luggage for hours?

Thanks in advance.

No. Access is one of the major challenges of climbing off-season.

Do you know if the Kawaguchiko train station have boxes to store luggage for hours?

We will try to access in a cheaper way in the afternoon.

Do you think that there will be more climbers in the first week of September? the question is not to go alone...

I'll attempt to do the climb the 6:th of September. I'll be starting at the Sengen Shrine in the morning, rest at the fifth station and the do a night climb to catch the sunrise.
