Rokando Limestone Cave, Sumita-cho in Iwate Prefecture, Japan
（Postscript on June 23, 2012）
There are lots of underground excavations inside the earth
and there is the rivers filled with clean water which is filtered.
Those water become the source of water for springs, qanats and springs
in the Roman era.
There is the two‐stage waterfall at the innermost place of
800 m cave, where surprisingly large amount of water
falls from the very high place（29 m high）.
(They say it is the highest waterfall in the Japanese caves.）
I was told through the channeling that this is the place
which shows spinal fluid is produced inside the skull and
it falls from the neck in order to pass through the spinal column.
