Explore Mt. Fuji Ice Cave in Aokigahara Forest

Tada our tour guide was just fabulous. Very informative and funny, kept us amused the entire time. From the walk through the forest to the walk through the cave, we enjoyed the day thoroughly. Highly recommended.

Excellent, Toshi definitely love what he does, it seems he owns the forest and the cave due to his knowledge familiarity and passion to this place. I thought I would get caught in the deep vibes of the forest but just the oposite, everyone was laughing and having good time, and the cave is amazing!!!

We had a fantastic time on our tour and highly recommend this beautiful and informative experience for anyone traveling to the forest!

The experience was amazing! Tada was a fun and a very knowledgeable person. Watching him navigate and explain everything about the forest was a pleasure to watch and experience! This is a must do!

Really interesting and unique experience. Well worth going if you’ve got the time. Communication, transport and location were all amazing.

Cool experience. It's in old volcanic lava tubes. We had a nice walk through the magnetic forest to get there. The forest is spectacular Our guide was very knowledgeable and pointed out lots of interesting things. We had great views of Mount Fuji at the start of the trip

The ice cave tour was great, It was better than I was expecting. Our tour guide, Takasi, was very knowledgeable about Mt. Fuji and the history behind it. You can tell he really enjoys what he does. Our group had a small child, and Takasi was patient with her and very friendly. I would recommend him as the tour guide if you book this trip. His friendly demeanor made it a worth while activity.

The tour guide (I wish I remembered his name) was great. Patient and very knowledgeable. He took his time and was patient when I stopped to take pictures of forest mushrooms. He even allowed us to take a moment to enjoy the scenery at the area we changed at to enjoy a moment in silence of Mt. Fuji. Thank you so much for your kindness and not canceling since it was just the two of us!

Our guide, Tada, led us into the Aokigahara Forest, also known as the Sea of Trees. The soil here is volcanic, dark and rich, the air thick with moisture and mystery. Every surface — every trunk, branch, and stone — was covered in soft green moss, giving the forest an otherworldly feel. It felt ancient, suspended in time. Tada explained that Ao means “blue-green,” a fitting name for this place that shimmers between shades of life. The forest sits on a network of 1,000 lava caves, remnants of Mount Fuji’s eruptions. “Stay on the trail,” he warned gently. The roots here twist above the ground like living veins, beautiful but treacherous. Tada has been mushroom hunting for over 20 years, his knowledge of the forest endless. He showed us the Wind Cave obelisk monument, marking the entrance to an underground ice cavern once used as nature’s refrigerator. Inside, the temperature never rises above freezing. The Japanese once stored food and silk cocoons here. When they brought the silkworms back into the warmth, the insects thought the seasons had changed — and produced silk five or six times a year instead of once. The perfect blend of nature, science, and ingenuity. The cave itself was hauntingly beautiful. Down at the deepest point, we turned off our headlamps at Tada’s request. Instantly, everything vanished — no light, no sound, just total darkness. It was the darkest I’ve ever known, an infinite quiet that pressed gently against your skin. We stood like that for three minutes, breathing together, letting the silence sink in. It was strangely peaceful, grounding — a reset for the soul. When the lights flickered back on, I felt lighter. And deeply grateful for AAA batteries. Outside again, the mountain air felt fresh and clean. The forest whispered, the moss shimmered in dappled sunlight, and time seemed to slow. After days of neon, noise, and motion, this was balance — calm and clarity.

The cave tour was phenomenal! Our guide was humorous, kind, and incredibly knowledgeable. We learned about the volcanic region, cedar forest, and historical uses of the cave. Highly recommend!
