The Ohira mine is located near Kyoto and I got these for $25 each on eBay. They are far from the best natural stones but they work well! I've seen much more expensive Ohira stones go up to 30k grit. Those are light beige colored not green like this one.
After lapping, it produces some slurry. The writings went away =/
Wet with clean water:
The stone is quite hard, harder than my synthetics. It is less porous and more dense than synthetics. The feel is on the slicker side, no gumminess or friction feeling.
I've only done one 63 rc carbon steel blade with it, the finish is a misty haze, yet leaving no scratches to the naked eye. Looks like a 1k finish with a fine 6k scratch pattern. It needs slurry and cuts slightly slower than the equivalent grade synthetic, but much faster than oilstones.
It whitens softer steel so it beings out the hamon quite well. No more acid etching for me!
If anyone wants to borrow one just let me know. They are fun to play with.
