5.00The 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.
We hope to come back and take another tour from this tour guide.

5.00The 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!
A mist filled trip back in time

5.00Our 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.
Phenomenal tour and amazing guide

5.00This was the highlight of our trip! We went as an anniversary adventure and ended up being the only ones on the tour. Our tour guide was extremely knowledgeable about the wildlife in the area and the cave was incredible! Worth every single penny. Highly recommend hiking shoes and light clothes for under the coveralls and I would not recommend for those that are physically limited in any way.
Excellent
