Does anybody know what the weather is like on the peaks? If you have any experience w/ these trails, please let me know.

when?

I am planning to hike Asahidake to Kurodake in two weeks.

There is a good chance of snow covering the peaks by the end of September.

I plan to stay overnight on the trail.

Camping is not allowed. You must stay in huts or at accommodations down in the lower elevations.

Does anybody know what the weather is like on the peaks?

It changes daily and cannot be predicted over more than a couple of days. But there is a high chance of freezing temperatures during the night and snow.

If you like you can use the following Youth Hostel as 'base camp' for your hiking trips:
