Reads on the stone top from the upper right down, JUN SHOSHIN HONYAMA (pure
specially chosen original mountain) which is a registered trade name.

And 27 (an inventory or grading number)

And at the middle SAIKOKYUHIN (very best quality)

Marked faintly on the end of the stone in a rectangle KA SHO HON YAMA (Maruka correct
true original mountain).

This Nakayama Maruka awasedo toishi stone is NEW/OLD stock from a closed store in
Japan. It has not been used other than to test the quality at one edge of the stone as you
can see in the photos.

You may find other references to the Maruka Nakayama mines on the internet. This mine
was known throughout its history to produce the finest awasedo finishing stones in Japan
and probably in the world. The Maruka stamp on the end, the registered stamp on the top
of this stone and the single toothed fine saw marks help to date the stone to before WW2

This is an actual Maruka Nakayama awasedo, it is not a fake. Stones of this color and
variety have not been mined from Nakayama for well over three quarters of a century and
they never will be mined again as these rare deposits are depleted. The mine was closed
in the 1960s and I will not be able to replace or offer these stones again.

This stone can be used without a nagura or DN plate and it will  build up a slurry without
too much trouble.
