Picking the best Naniwa Chosera grit starts with one fact: Naniwa’s famous Chosera line is now largely sold as Naniwa Professional (SS), with the same thick, splash-and-go stones on a base. Most cooks only need two or three grits from the range, so choosing the right ones matters more than buying them all.
We compared six Chosera and Professional stones from #400 to #5000 by role, feel and how they work together, and suggest simple kits for different kinds of cooks.

How We Chose the Best Naniwa Chosera Grit
To choose the best Naniwa Chosera grit, we compared each stone’s role, size, base and dressing stone, then read owner feedback on speed, feel and how the grits pair together. We also looked at price per millimetre of usable stone, the quality of included holders and how clearly each maker explains soaking, flattening and care, since those details shape how pleasant a stone is to use week after week.
Wash your knife and board after sharpening, following USDA Food Safety and Inspection Service cleanliness guidance. Our method is on the How We Test page.
Buying Guide: How to Choose the Best Naniwa Chosera Grit
Chosera vs. Professional
Naniwa’s Professional (SS) stones continue the Chosera formula; listings may use either name. Both are thick, splash-and-go stones on a base. If you find an older Chosera stone at a good price, it will work the same way as a current Professional stone of the same grit.
Two-Stone Kit
#1000 plus #3000 gives a sharp, toothy edge with little effort. It suits most home cooks. The #3000 finish grips tomato skins and onion layers well, and it is quick to reach from #1000 without a middle step.
Three-Stone Kit
#400, #1000 and #5000 covers repair, sharpening and a refined finish. This kit suits cooks who own several knives in different states, from chipped utility knives to well-kept gyutos.
Splash and Go
These stones need only water on the surface; avoid long soaking, which can weaken the base. A light spray before and during sharpening is enough; the stone builds its own slurry as you work.
Flatten and Store Dry
Flatten with a diamond plate and let the stone dry fully before storing. Avoid storing the stone in a closed case while it is still wet, since trapped moisture can lead to cracks over time.
Tips for Naniwa Chosera Stones
- Splash water on the surface instead of soaking.
- Use the dressing stone to refresh the surface.
- Flatten often, especially the #400.
- Rinse the knife between grits.
- Let stones dry fully before storing.
