Starting in the 2025 climbing season, climbers will be required to wear proper clothing and gear or risk being turned away from Japan’s most iconic mountain. This isn’t just a fashion suggestion—it’s part of a larger push by local governments to protect both people and the environment as overcrowding and accidents increase.
Why the New Dress Code?
Over the years, too many visitors have shown up to Mt. Fuji in shorts, hoodies, or even sandals, treating the 3,776-meter volcano like a casual hike. But Fuji is no joke. Temperatures at the summit can drop below freezing, even in the middle of summer. Add in wind, rain, and altitude sickness, and you’ve got a recipe for disaster—especially if you’re underdressed.
Authorities in Yamanashi and Shizuoka Prefectures are now saying enough is enough. The new rules aim to ensure climbers are properly equipped, not only for their safety but to reduce the burden on emergency services.
What You’ll Need to Wear
If you’re planning to tackle the mountain in 2025, here’s what counts as “proper clothing”:
- Sturdy, high-cut climbing boots (not sneakers)
- Layered clothing like quick-drying base layers, fleece or wool sweaters, and down jackets
- Accessories such as gloves, a neck warmer, and a warm hat
- Durable, separate rainwear (umbrellas and cheap vinyl ponchos are a no-go)
- Headlamp for night climbs or early starts
Jeans, cotton T-shirts, and city-style raincoats? Definitely not recommended.
How the New Rules Work
The clothing requirement is part of a new online reservation system for the popular Yoshida Trail. When booking your climb, you’ll need to agree to terms that include wearing appropriate gear. If you show up in gear that doesn’t meet the guidelines, you might be turned away.
Meanwhile, Shizuoka Prefecture, which manages three other trails (Fujinomiya, Gotemba, and Subashiri), will roll out a similar system. Climbers there must also register online, take a brief safety class with a quiz, and confirm they understand the trail rules.
Other 2025 Requirements
In addition to the dress code, here are a few more things you’ll need to climb Mt. Fuji next year:
- Climbing fee of 4,000 yen (about $28)
- No littering or straying off trail
- Reservations required—no walk-ins for the Yoshida Trail
These rules are part of a broader effort to manage the growing crowds, reduce environmental damage, and make the Mt. Fuji experience safer for everyone.

What This Means for Climbers
While some casual hikers may be put off by the new rules, many in Japan are welcoming them. Social media reactions show strong support for safer and more respectful climbing practices. And serious hikers? They’ll probably appreciate the reduced crowding and improved trail conditions.
So if you’re dreaming of watching the sunrise from the summit in 2025, start prepping your gear list now—and leave the flip-flops at home.
