Explore Mt. Fuji Ice Cave in Aokigahara Forest

Exploring the Mt. Fuji Ice Cave in Aokigahara Forest: A Truly Unique Adventure

If you’re looking for an experience beyond the usual sightseeing around Japan’s iconic Mt. Fuji, this tour offers something special. It takes you into the hidden depths of a natural ice cave, formed over a millennium ago by lava eruptions and Mt. Fuji’s melting snow. The small-group guided format makes it intimate and manageable, even for those with moderate fitness levels, and the inclusion of special entry permits ensures access to this seldom-visited wonder.

What makes this tour stand out? We love the way it combines a beautiful, mysterious forest with an underground world of ice art—something you simply can’t find elsewhere in Japan. The expert guides, like Takashi and Tada, are packed with knowledge and passion, sharing insights about the area’s flora, fauna, and volcanic history. But beware—it’s physically demanding at times, with rocky terrain inside the cave and a 40-minute walk through the forest, so it’s best suited for travelers with a moderate fitness level.

The Itinerary Breakdown

This three-hour experience begins with a convenient pickup from Kawaguchiko Station or nearby hotels, which means you avoid the hassle of arranging transportation—an appreciated touch. Once picked up, your guide equips you with a helmet, headlamp, gloves, and a full-body overall, preparing you for the variable outdoor conditions.

The trek into Aokigahara Forest is about 40 minutes long, during which you’ll walk beneath the dense canopy of this famous “Sea of Trees.” Guides like Takashi impress with their deep knowledge of the flora and fauna, pointing out mushrooms, trees, and wildlife along the way, which adds an educational element to the walk. Many reviews mention how peaceful and mysterious the forest feels, with some describing it as another world—an ideal setting to build anticipation for what’s to come.

Once inside the cave, the adventure truly begins. The lava tubes formed by ancient eruptions are carved into solidified lava, creating a maze-like underground environment filled with ice structures, stalactites, and natural sculptures. The temperature inside hovers around 0°C, so the provided gear ensures you stay warm while exploring the icy formations. Some reviewers note that maneuvering through rocks and narrow passages can be tricky, especially if your footwear isn’t grippy, so sturdy shoes are advisable.

The cave exploration lasts roughly an hour, during which your guide will highlight interesting features and explain how the ice art was formed through snowmelt from Mt. Fuji. You’ll also access the “Real Cave,” a secluded section that has yet to become a tourist attraction, giving you a sense of discovery and exclusivity.

After the cave, the walk back through the forest adds a serene, reflective ending to the trip. The entire process is well-paced, but flexibility is built in, so expect some variation depending on weather and group pace.

The Environment and Safety

The rugged terrain inside the cave requires caution. The rocky floors and ladders mean that this isn’t a tour for anyone with mobility difficulties or pregnant women.

The tour is designed for visitors with moderate physical fitness, and the uneven terrain makes it more adventurous than a typical walk.
