Very nice stone.
Japanese Natural Stones, Kanji & Information
I hope it’s ok to post this link here. I also hope it will be new to some of you. There is a wealth of information about Japanese naturals, as well as some side links covering the history and brands of Japanese razors which I found enlightening.

Very pretty stone you have there. What are its characteristics? If it were me, I would most definitely seal the sides and bottom.
This Okudo Iromono maybe one of the finest stones I have. Further testing will tell, but the shave tonight was phenomenal.
Lapped the second Okudo from my Japan package. Looks a lot like another stone I have. The mud is very silky with very fine micro bubbles. One thing I really like about this one is it has full kawa on the three long sides and even a bit in the crevice on the end.
Narutaki from Nakayama
Fun
Fun
Buying in bulk now I see. Lol. Nice looking stones, Tom.
David, I couldn’t make up my mind so I bought them all. The Narutaki from Nakayama I just bought 1kg and ended up with 3 of them. My arms hurt.
All the Okudo are excellent hard tomae Iromono for sword polishing. Here is a really nice one I just lapped.
No sun today so this is the best I could do. Hard to see all the purple running through this Nakayama in pics.
Looks like some old school kiita....fast cutter?
This was a rough chunk that took me a while to get flat. These were sold as Narutaki Koppa High Quality Nakayama 1kg and are supposed to be fast cutting and the finest stone for sword polishing according to Namikawa. Does seem like an old school kiita though. Seems fast from preliminary test runs, but I still need to test it fully. Sometimes stones cut real fast right after lapping and once you stop using the DN plate and switch to a tomo they will slow down as the stone gets more polished. This can also depend on how hard or soft the tomo or the base stone is. I will probably do some testing this weekend.
Got another of the Narutaki Nakayama’s flat and in use.
hi guys.
can you help me identify my stone, please?
It's most likely from a quarry in or around okayama.
Looks like uchigomori?
I got no idea, as i'm a DE man myself.

This is always the case with harder stones, not sometimes. Softer stones aren't so different in speed between DN slurry and tomo slurry because many more and larger particles come loose with a tomo when the stone is on the softer end of the scale.
With harder stones, a DN can pull many large and sharp edged particles loose into the slurry while also leaving the surface of the stone with relatively deep and sharp edged grooves, while a tomo mostly just rubs and smoothes/dulls the surface of the stone, removing much less and smaller particles. If you think about it, it's pretty easy to see why a DN generated slurry will cut much faster than one made with a tomo.
Softer stones will be the same as harder immediately upon lapping with DN but they are so soft they release all those particles immediately and go pretty much right back very rapidly to how they would be with a tomo generated slurry.
My first finisher stone (I've been using CrOx/IrOx and lapping film). Planning to use it to maintain an edge after bevel set for hopefully many shaves.
Shobudani Mizu Asagi Aswedo Jnat. Very hard and fine stone. Sides sealed with Cashew Lacquer.
6.25” x 2.1” x 0.6"
Any tips welcome. Purchased from @Andy77 on the marketplace BST and he provided a tomo to get me started out.
I wet the stone and tomo and ran the tomo across to build slurry. Ran the blade across for 20 or so passes. Used the side that looked glossy with varying patterns as opposed to matte side. Washed it all off and did another 20 passes then took the blade to the strop for 60 passes. Tree topped well and will try a shave in the next day or two. I feel like it will be a good one. Hopefully bloodless.
How often do these need to be lapped and what should I be using?

Looks like a solid stone
Here’s one of my Jnats top flight finisher, killer edges. It’s a Shoubudani it had a stamp on it but it’s wore off from honing.
Greetings and welcome to the world of Jnats.
I use a "coarse" 8 inch DMT plate to lap my stones. I usually touch up or hone once a month so I lap the stone lightly every time I use it. If I am unsure of the stone's flatness I will pencil in hatch marks across the entire surface of the stone edge to edge and lightly lap those marks off. When the pencil grid pattern is gone I am sure the stone is flat.
My method involves 40 light circles on both sides of the blade followed by 60 laps starting with a heavy slurry and diluting the slurry every 20 laps till I am left with a very, very light slurry and using very, very light touch on the stone.
My stone is very hard and fast so this methodology may or may not be best for you and your stone and technique.
Best Wishes,
