Question 1

Do I need a permit or reservation?

Accepted Answer

No permit or advance reservation is required. A ¥4,000 entry fee applies on all four trails, but you can pay on the day at the 5th station. Advance booking through the official Fujisan Climb portal is optional — it guarantees entry on busy days (especially weekends and Obon week) when the Yoshida Trail daily cap of 4,000 climbers may be reached.

Question 2

Can I climb in one day without sleeping?

Accepted Answer

"Bullet climbing" — going up and back without sleeping — is no longer permitted between 2pm and 3am. A hut reservation is required if you pass through during those hours.

Question 3

Is altitude sickness a real risk?

Accepted Answer

Yes, genuinely. Even fit climbers experience headaches, nausea, and dizziness above 3,000m. Most 2-day itineraries include an overnight hut specifically to help you acclimate.

Question 4

What is the climbing season?

Accepted Answer

Official season is July 1 to early September. Trails are closed outside this window — huts are shuttered, and the weather is genuinely dangerous without mountaineering experience.
