Aokigahara Trail
Aokigahara Forest Guide Tour
The Aokigahara Jukai Forest is a woodland that has grown upon a lava plateau formed by ancient eruptions of Mount Fuji. As a forest still in its developmental stages, the Jukai presents a harsh environment with minimal soil and water. Here, both flora and fauna have evolved unique strategies to survive. Careful observation reveals a multitude of fascinating discoveries. Walking through the Jukai significantly enhances one’s ability to perceive the intricacies of the forest. And of course, with its many captivating photo opportunities, it’s also highly recommended for photography enthusiasts.
Aokigahara Forest and Sankodai Viewpoint Guide Tour
This special Jukai Forest tour includes a visit to the Mihokodai (Three Lakes Plateau), offering panoramic views of the vast Aokigahara Jukai Forest. From this vantage point, you can see Mount Fuji and its parasitic volcanoes, and on clear days, even the Southern Alps. Overlooking Lake Saiko, Lake Shoji, Lake Motosu, and the expanse of the Jukai, this location allows you to truly feel the dynamic forces of the Earth.
