A Blue World Opening up Deep Inside the Ryusendo Cave.
Ryusen-do Cave is known as one of Japan's three greatest limestone caves and has been designated, together with bats living in the cave, as a national natural treasure.
The total length of the Cave, as far as is known is 4,088 m, of which 700 m is open to the public.
So far, eight underground lakes have been found, of which three are open to the public.
Exploration continues to this day and there is still much remaining to be investigated. The Cave is thought to extend to a total length of 5,000 m or more.
Stalactites are nature's work of art created over countless ages.
The underground lakes have brilliant blue water that is amongst the most transparent in the world.
You can be sure that even after one viewing of Ryusendo Cave, you will be left with a life-long memory.
