Trohki Waterfall is highly unusual; there is onlyone other like it in all of Japan. Trohki is just 5 m high and unleashes its waterinto the sea instead of a river or lake. The degree of its surge depends on thetides, but it can be quite wide. The name Trohki comes from the Japanese word todoroki, which refers to a roar or echowithin nature such as lightning or thunder. In Japanese, then, the waterfall’s namemeans Roaring or Thunderous Falls.
Visitors are prohibited fromgetting close to the falls, so it is possible to listen to the thunder of TrohkiWaterfall echoing only from a distance. Two observation points offer magnificentviews of the falls with Mt. Mocchomu in the background. The first of these observationdecks is located down the path opposite the Pon-tan kan building. The narrow pathgradually goes deeper into the woods and provides the closest view of the falls.Sometimes small orange crabs can be spotted along this route. The second observationdeck is located in the Yakushima Botanical Research Park. The view from this deckis slightly better, but requires an entrance fee of 500 yen per adult.
