Well, concerning 10K I would not say I had a great shaving before, since usually I finish with Escher or similar Thuringian.. This is my first experience with JNAT.
When you mean no naguras you mean to avoid botan, tenjyo e t c? Yes, I did try with diamond 1000 k as well. The result is still not the best.. So I tried naguras set. Diamond plate. Water only strokes.. 50 strokes.. 100 strokes.. but can not feel its getting sharp enough.
The face of the stone was flattened with SK11 diamond plate first 400 grit then 1000 grit. Plate is quite ok since I also used for it for the other stones and it still works perfectly. The face of Ozuku after lapping looks like it does not have any foreign inclusions.. I mean stone does not look suspicious. Came with
大突
and
本撰
which are gone after lapped flat

What do you normally finish on before Escher?
If you can get a good edge on a Thury from ? You should easily get a decent edge from your Jnat.
I am not of the belief that you have to "unlock" a stone's magical code to get it to work. Its really not complicated.
From a decent 8k or better edge you should be able to use any other finisher either with water or oil alone (whatever medium the stone dictates) or a light slurry.
Very broadly - Razor quality Jnats can seem too keen when used with water alone so using a light slurry will smooth the edge some.
Using Nagura Tenjyou, Mejirou etc creates too many variables. They are for using your base stone when starting at a much lower grit - 1k-3k for example.They are a progression just like synthetics.
When testing a finish stone I always start at 8k synthetic as a baseline. It should improve that edge.
