The Gouken Arata is the slim line version of the well renowned, full sized Naniwa Chosera used by professional sharpeners all over Japan. Lighter, more affordable, and portable; the Arata feels identical to the Naniwa Chosera and comes with a plastic case that doubles as a stand.


Medium grit #1000.


The Arata line of stone is split between 3 levels of abrasion Coarse, Medium and Fine. The #1000 Arata is one of the best stones in the series, and is aggressive enough for most maintenance while leaving an edge that is slightly more refined than other 1K stones.

We recommend soaking the Arata stone for only 2-3 minutes for initial sharpening, after the whetstone has been soaked it can be splashed with water to keep the surface wet. Once finished sharpening clean the stone and allow it to air dry naturally.


Suehiro's goal with their company is to reduce the stigma around using whetstones to sharpen knives and tools as opposed to through them out once they are dull.

Whetting knives is neither difficult nor dangerous. If you have one versatile whetstone at home, you can whet not only cooking knives but also various kinds of knives and blades you have. Even from the perspective of cherishing what you use, we’d highly recommend using whetstones.
