This place is said to be the birthplace of Ninja.
Along the hiking trail is an encounter of series of refreshing scenery of grandiose waterfalls in Mie's pristine, ancient rainforests.
The most notable among the numerous falls are: Fudo falls, Senju Falls, Nunobiki Falls, Ninai Falls, and Biwa Falls.
This falls haven is at its best during fall, where the autumn foliage adds color to the sparkling, downpouring water.
Before the hiking trail, there is also a Salamander Center where you can get to know about the giant salamander, a rare animal found in Japan.
There is also a Ninja Training Experience offered by the local tourism organizations there. (Visit their website for more details about the training.)
The nearest station coming from Kyoto Station, Nagoya Station, and Osaka Nanba Station is "Akameguchi Station" (Kintetsu Osaka Line). From there, take the Miekotsu Bus.
Entrance fee costs 300 yen (adults and high-school students), and 150 yen (elementary and junior-high school students).
It's open all year round, except on December 28-31.
