Saiko Bat Cave

The Saiko Bat Cave is Aokigahara’s starting point for this sample course.
While this sample course provides information for visitors conducting their walk independently, at the Saiko Bat Cave Information Center, an Aokigahara “sea of trees” nature guided tour is available for an additional fee. The guided tour offers you an enjoyable walk in the woodlands while listening to easy-to-follow explanations about the nature from experts with accurate and extensive knowledge about the nature found in the Aokigahara woodlands and who are qualified as nature guides by Fujikawaguchikomachi.
Before starting the walk, let’s go explore the Saiko Bat Cave.

All trekking courses take approx. 70-90 min.

Start point for the Aokigahara trekking course.

Depart from the Saiko Bat Cave parking area for Aokigahara trekking.

Immediately after the starting point, there is a crossroads. Walk to the left of this sign (in the direction indicated on the sign as “Yachonomori Park(Wild Bird Park)”).

The woodlands’ walking trail offers a very pleasurable experience of a therapeutic walk through the woods.

Visitors may not leave the walking trail to enter the woodlands area.

200m after the starting point, you will see a sign which reads “Monotropastrum humile.”
The white Monotropastrum humile are like fairies of the forest.
In general, plants are green because they contain chlorophyll, a nutrient obtained from photosynthesis. However, these Monotropastrum humile are white because they do not photosynthesize and thus have no chlorophyll. Plants that do not photosynthesize, like these Monotropastrum humile, are called saprophytic plants.
Saprophytic plants grow by absorbing nutrients derived from decomposing fallen leaves and other organic matter via fungi.
They are found widely around the end of May until the beginning of July in the Aokigahara woodlands and other slightly moist mountain areas.

While enjoying the moss-covered view, 400m from the starting point, you will see a sign for “jaybirds.”
In the Aokigahara woodlands, you can see many kinds of wild birds such as the great tit, willow tit, long-tailed tit, magerahigara, higera, great spotted woodpecker, pygmy woodpecker, bush warbler, Eurasian jay, Japanese white-eye, Japanese thrush, brown-headed thrush, Siberian thrush, Hodgson’s hawk-cuckoo, Japanese grosbeak, lesser cuckoo, black-faced bunting, Oriental turtle dove, and common cuckoo.

Here there is a zone of enormous 300 year-old Southern Japanese hemlock trees.
Tree roots are found even within the walking trails within the woodlands. Please avoid stepping on these roots while walking.

600m after the starting point, you will see a sign which reads “Rhododendron keiskei.”

This is a cave for taking shelter from the rain.
While it is possible to look around, you will see that the moss around here has been trampled and lost and you can tell that the surrounding trees have weakened.
In the Aokigahara woodlands, trees grow atop lava flows and therefore their roots cannot penetrate deeply into the soil. As a result, this is a delicate forest in which even tiny changes in the environment could result in the trees falling.

Here you will see an unusual Japanese cypress tree shaped like a mythological eight-tailed serpent.

You will see a sign which reads “Guide to Weasels.” The Aokigahara woodlands is home to many kinds of animals such as bears, deer, foxes, boars, wild rabbits, Japanese minks, and squirrels.

The bark of this tree has been peeled away by visitors and therefore is gradually weakening. Please show respect for the valuable forest.

You will now find yourself at an intersection 900m from the starting point. This is the crossroads enabling you to proceed in the directions of the Lake Saiko lakefront, Yachonomori (Wild Bird Park), Fugaku Wind Cave, or the Ryugu Cave.
Near here, there is a “watering hole” for birds.
You will see a signboard which reads “Aokigahara woodlands map”, so please check your route thoroughly here.
This sample course proceeds toward the Lake Saiko lakefront.

Trees shaped like deer that look as though they come from animated films or fantasy movies, traces of where lava had flowed, and the dynamic scenery of lava and trees—each of these parts of the natural environment comprises the attractiveness of the Aokigahara sea of woodlands.

At the Nenbahama entrance/exit for the Aokigahara woodlands walking trail, come out to the roadway for a little while.

Cross the road and you will see the sign which reads “Aokigahara woodlands map, Nenbahama signboard”. From this point, you will proceed to the Lake Saiko lakefront.

Continue walking towards the Lake Saiko lakefront. If you help pick up any litter you find, the splendid nature here will be even more stunning.

At Nenbahama on the Lake Saiko lakefront, you can see the shape of Mt. Fuji. This is a moment that will move you!

Head towards the Nenbahama parking area.

Now you have arrived at the Nenbahama parking area, the finishing point. There is a place for you to rest, as well as lavatories.
