Enjoy nature through a walking trail and an active camp

One characteristic of Lake Sai is the Aokigahara Jukai Forest which spreads out in the vicinity. On the Aokigahara Jukai Forest Walking Course, you can sense the mystery of nature created by Mt. Fuji. PICA Fuji Lake Sai on the shores of the lake has a campground and other accommodations including cottages. On the lake right by the camp, you can enjoy fishing, canoeing and boating. The very large dog park within the grounds is popular with tourists bringing their pets.

The Yacho-no-Mori Preserve for wild birds

The Yacho-no-Mori Preserve is a treasure trove for about 210 species of wild birds surrounded by Aokigahara Jukai Forest. There are feeding stations in the park and a birdwatching room equipped with telescopes. There are also seasonal events, and the highly popular Lake Sai Juhyo (frost-covered trees) Festival is a sure sign of winter. Works of art made from ice such as waterfalls and kamakura houses are on display, and the frost-covered trees which can soar up to 10m are very spectacular. These works take on a wondrous hue when various colors of lights are used in the evening.

The caves found during a stroll

There are unique lava caves created from lava flows from Mt. Fuji, half of which can be found in Aokigahara Jukai Park. Among them, the largest Komori Ana (Bat Cave) is more than 350m long. Different from the average cave, it is warm in temperature and since the old days, it has been a hibernation place for bats, and at present, there is a sanctuary for the bats in the back of the cave. There is also Ryugu Cave among the countless number of caves in the forest which leaves a deep impression. Senoumi Shrine is a full-fledged shrine located in Ryugu Cave; although you cannot enter the cave, you can go as far as the entrance where the shrine is located to worship.
