  • Ryusendo is counted as one of Japan's three great limestone caves (the other two Akiyoshi-do cave and ryugado). Still in the ongoing investigation total length is approximately 3 km extension of the known range, as an unknown, out of 700 m has been disclosed publicly. Lit cave stalactites and underground lakes and the fantastic. As the underground lake is highly transparent, are praising the water really do not know, is really beautiful. Properly maintained, and is open to the public, including light, easy walking because while some must also pay attention to the above passage is wide enough, you can enjoy the stalactites and underground lake. ... Easy walk & sinus ryugado when at a later date, to how. I think so but there are passages on the way up the stairs treads a fine entrance way came back, people with anxiety and notes, always secure the stair well, physique and physical fitness some people who have anxiety Cave Tour. However, still walking shoes recommended. Whatever the season, the cave temperature is constant in the sweaty season comfortable cave. Is that of the 8/2016 Typhoon No.10 by the water spilling from ryusendo, is currently in a closed, even the resumption of undecided.
