One of Japan's Most Celebrated Natural Finishing Stones
Nakayama is widely regarded as one of the finest sources of Japanese natural whetstones. Located in the Umegahata region of Kyoto, the mountain produced exceptional finishing stones prized by generations of sword polishers, woodworkers, razor users, and knife enthusiasts.
Known for their smooth sharpening feel, refined abrasive particles, and beautiful edge finish, Nakayama stones have become some of the most sought-after Japanese natural whetstones.
The Legacy of Kato Mine
Nakayama, in the Umegahata area of Kyoto, is widely regarded as one of the finest sources of Japanese natural finishing stones. Kato Mine (加藤鉱山, Kato Kozan) is the mine on Nakayama owned and worked by the Kato family, and its name and stamp still mark stones from there.
Every Natural Stone Is Unique
Unlike synthetic sharpening stones, no two natural whetstones are exactly alike. Even stones originating from the same quarry or geological layer can vary noticeably in use.
- Sharpening speed
- Abrasive feel and feedback
- Mud generation
- Scratch pattern
- Polishing characteristics
- Hardness
These variations are an important part of the appeal of Japanese natural whetstones, with each stone offering its own individual sharpening characteristics.

This listing is for a Koppa-size Nakayama natural finishing stone. Koppa are smaller or irregularly shaped stones cut from usable sections of natural whetstone material.

- Straight razors
- Detail sharpening and polishing
- Exploring different natural stone characteristics
- Collectors of Japanese natural whetstones
