滝観洞 (Rokando, Waterfall Cave) is a river cave with numerous small waterfalls and rapids. The tour follows the main passage for 880 m until it reaches a 60 m high shaft with a diameter of 16 m. The water emerges from a crack high above and forms the highest waterfall in any show cave in Japan with a drop of 29 m named Ama no Iwato no Taki (Amanoiwato Falls, Waterfall of the Heavenly Cave). The name was given by the passionate female poet Byakuren Yanagihara (*1885-✝1967). She visited the cave at age 73 in 1958 and actually made it to the waterfall. She later wrote the poem "Amanoiwato Waterfall" for the waterfall of Rokando Cave.
Although this cave is officially a show cave, the tours are actually quite rough. As soon as they enter the tiny entrance visitors are forced to crawl on their hands and knees for several minutes. The main passage is very low, only slightly higher than your head, and larger visitors (aka Westerners) are stooping most of the time. There are random Buddhist statues along the way so visitors can pray for strength, and a prayer is also a time of recovery. And before you reach the final waterfall chamber, there is again a section which requires crawling.
We would classify this cave as a very easy cave trekking tour, but officially it is a show cave. There are trails and electric light, just no tunnel for the low sections. Japanese, who are very petite and agile, have far fewer problems than adult caucasians. Visitors typically wear helmets, a windbreaker, and gumboots, which are provided by the staff. The river cave is mostly clean, just wet, nevertheless you might get dirty. Sturdy shoes and clothes you might wear on a hike are definitely a good idea. We suggest bringing your own, if you have, its more comfortable, and a good headlamp on your helmet is never a bad idea. For people of "normal" size and higher we also suggest knee-pads and gloves, which makes the crawling much more comfortable. A towel and dry clothes to change are probably also a good idea.
The cave became widely known in Japan in 1977, when it was a filming location of the Japanese movie 八つ墓村 (Village of Eight Gravestones). This movie has become a classic, and today there are numerous films, series and mangas with this story. The first detective novel of the Kindaichi Kosuke series was written by Seishi Yokomizo.
