It was an amazing experience to explore beautiful Aokigahara forest and ice cave. Takashi-san is very knowledgeable about local flora and fauna, we learned a lot during the tour ✨

This tour was hands-down one of the most unique and memorable experiences of our time in Japan. From the moment we were picked up promptly at Kawaguchiko Station, everything ran smoothly and felt incredibly well-organized. Our local guide, Tada, was outstanding—friendly, professional, and full of fascinating knowledge that really brought the experience to life. The train station and car ride offered breathtaking views of Mt. Fuji, and we stopped at a scenic spot to take photos. But the real adventure began when we entered Aokigahara Forest—a place as beautiful as it is mysterious. Known internationally as the “suicide forest,” Tada handled the subject with incredible respect and care. He helped us understand the cultural and geological history of the forest. The cave itself was stunning—an icy, otherworldly landscape hidden beneath the forest floor. It's a natural wonder that you simply can't explore without a guide, and descending into it felt like entering a hidden world beneath the earth. We were fully equipped with helmets, flashlights, overalls, and gloves, and Tada ensured our safety every step of the way. The cold underground atmosphere was absolutely mesmerizing. Throughout the tour, Tada’s guidance made all the difference. His clear English, calm demeanor, and deep knowledge made us feel safe, informed, He also took the time to answer all our questions and shared personal insights that made the experience feel intimate and authentic. If you're looking for an off-the-beaten-path adventure that combines natural beauty, history, geology, and emotional depth, this tour is a must. It was far more than just sightseeing—it was an unforgettable journey into one of Japan’s most intriguing landscapes. From start to finish, this tour was well-organized, educational, and packed with moments that left us in awe. Highly recommended for nature lovers, explorers, and anyone wanting a deeper look at Japan’s natural wonders. Thank you, Tada, for an incredible experience we’ll never forget!

Exploring Aokigahara Forest was both peaceful and a little mysterious, with the dense forest feeling like another world. The ice cave nearby was cool (literally!) and a fun contrast to the forest hike. Our guide shared great insights about the area's history and nature, and pointed out neat facts along the way. Definitely a must-do if you're visiting the Fuji area!

Both Aokigahara and the ice cave were stunning. The cave requires a bit of maneuvering around and through rocks, which can be tricky/daunting, especially if your shoes don't have any grip. So glad we decided to book this. Our guide was well informed and passionate about the area, which showed through his interactions with the group. I appreciated his candor, humor and knowledge. Would happily book again, highly highly recommend

An amazing experience with the best guide, Tadasuke. I thought the tour was going to be brief but there was a pleasant hike and cave spelunking! The cave lived up to its name—Ice Cave. Truly a unique adventure.
