Question 1

When is the Mount Fuji climbing season?

Accepted Answer

The official climbing season runs from early July to early September. Outside this period, mountain huts are closed, trails are unmaintained, and conditions are extremely dangerous. Before climbing, always check the weather forecast and climbing index — when the index is C, climbing is not recommended.

Question 2

What do the climbing index grades A/B/C mean?

Accepted Answer

A (Good) means weather conditions are suitable for climbing; B (Moderate) means some conditions are unfavorable — exercise caution and make conservative decisions; C (Dangerous) means conditions are hazardous and climbing is not recommended. The index is calculated from temperature, wind speed, precipitation, visibility, and other factors, for reference only.

Question 3

Accepted Answer

In 2026, all trails require a ¥4,000 entry fee (payment via official website/app or on-site). Shizuoka-side trails (Fujinomiya, Subashiri, Gotemba) also require pre-registration, and the Yoshida Trail caps daily climbers at 4,000 with online reservations required.

Question 4

How many climbing routes does Mount Fuji have?

Accepted Answer

Four main routes: the Yoshida Trail (most popular, most facilities), the Subashiri Trail (rich vegetation, fast sand-slide descent), the Gotemba Trail (longest distance, fewest people, quietest), and the Fujinomiya Trail (shortest distance, greatest elevation gain).

Question 5

What gear should I prepare for climbing?

Accepted Answer

Essential gear includes waterproof hiking boots, warm layers (layering system), rain gear, a headlamp, enough water (at least 2 liters) and food, sunscreen, and a hat. Trekking poles and a supplemental oxygen canister are recommended to prevent altitude sickness — maintain a slow, steady climbing pace.
