Japan has numerous megalithic structures of ancient origin

The 500 ton Ishiro Hodin is cube shaped
It has tapered ends with sharp clean angles and a smooth surface

Ishiro Hodin means floating stone because water continuously flows from beneath it
And has 2 vertically oriented flat rectangular parallel pipe heads

It was formerly a component of an electrical generator that energized water
And part of an advanced hydraulic system that contained a vast subterranean system of channels

The Ishiro Hodin can be compared to the Osirion in Egypt and the Coliseum in Rome

In Uyama Kofun and Iri Nohodin
Massive stone boxes are found

They have perfect 90 degree angles at the corners
And have knobs which suggest sound reverberation

They are made of pink granite
And their surface is polished smoothly with extreme precision

They are similar to the stone box in the Kings Chamber in the Great Pyramid of Giza
And to the boxes wedged in the niches in the Serapeum

Near Asuki is the Soka Fun Stone
It is circular and hollowed out

The Kamishi Turtle Stone
Is a carved out stone resembling a huge turtle
It has a shell a head and legs

The Kamishi Turtle Stone has magnetic properties and changes its orientation
Local residents view it as a geophysical warning device

In the same area there is a massive shaped stone called the Demons Washing Stone
And another megalith called the Demons Cutting Board

The Ishi Butai Kofun is a structure with a colossal 140 ton slab for a ceiling

All these were part of an enormous electromechanical system
Which was destroyed when the previous civilization was overthrown!
