Mt. Fuji’s Eruption, Ancient Lake and Aokigahara Jukai

Over 3000 years ago, at the foot of Mount Fuji, lay a vast lake called Senoumi. Subsequent volcanic eruptions and lava flows divided this lake. In AD 864, a significant eruption from the base of Mount Fuji produced an immense amount of lava. This lava flow devastated the surrounding forests and filled a large portion of the original lake. The remaining parts of Senoumi are now known as Lake Saiko, Lake Shojiko, and Lake Motosuko, all of which were once a single, large lake. The forest that subsequently grew on the solidified lava is called Aokigahara Jukai.

We guide tours primarily in this area, where the dynamism of Earth’s activity is readily observable, offering a blend of raw power and serene beauty. By understanding and observing the survival strategies of plants and animals thriving in the harsh conditions of limited soil and water, we believe your perception of nature will deepen significantly. This enhanced understanding, we feel, enriches life itself. Furthermore, this site will introduce you to lesser-known recommended spots and the best places to visit in each season around this fascinating region.

All our tours are private, ensuring a personalized experience. In addition to our two recommended plans, we also offer custom-made itineraries tailored to your specific requests. For your convenience, pick-up and drop-off services are available at Kawaguchiko Station and hotels within the Lake Kawaguchiko area.
