My first Jnat. Is this a Kiita?

[BeJay]

I'm new to Jnats and I'm in the process of buying my first. I was working on a restoration with dshaves and he brought this stone for me to try. Now, I've never had much of interest in Jnats. I've had a few Coticules that I liked okay, but mainly I like my Naniwas. This thing was in my house though, so I was eager to try it.

I decided to try it out on a 7/8 Wade & Butcher that I had just restored and finished on a Nani 12k the day before. This would give me a nice reference since it was just finished and shave tested. I gave it 30 laps on the Jnat with only water. The test shave was fantastic and a very noticeable improvement! He let me hold onto it and I've been experimenting with it all week with really good results. I've gotten the best results by raising a slurry and diluting down to pure water.

The seller that dshaves bought it from sold it as a Nakayama Namito Kiita Sumanagashi. I know that Nakayama is the mine and Kiita Means it's yellow, but I'm not sure what Namito and Sumanagashi mean. This also doesn't look like any of the other Kiitas that I've seen, due to the various colors and patterns. .

Any info on this stone or tips for using it would be very much appreciated.

Here's a few pics. The first is dry and the second is wet.
