This movie is Mt. Daisen(1709.4m 5608ft) in Tottori Prefecture.
It is one of the typical mountains in West Japan.
The north wall appears gradually when it climbs a lot of beechen mountain climbing trails.
The board walk is maintained in the vicinity of the top of a mountain.
The view of the Sea of Japan can be done.
Kengamine of the highest point is off-limits because it is dangerous.
This is Rakudano-se(Camel's back).
The left side is the north wall. The right side is the south wall. Both sides are precipices.
It is hundreds of-meter slip drop when falling because the tree has not grown in the precipices.
There is only one step width. It walks like the balance beam.
