Found this store on Alibaba's Taobao mall:
https://shop129114686.world.taobao.com/shop/view_shop.htm?spm=a312a.7700714.0.0.ZzDOaz&user_number_id=1990364398It features Go products from only certified Japanese master craftsmen, all in one place. And it ships to the US. For those of you who have been having a hard time finding Japanese equipment online, this Taobao store might just do the trick.
Also the prices are fair, as in not above or below what you'd expect.
If you don't read Chinese, Google translate seems sufficient (which is what I used).
Other Japanese equipment makers have also set up shops on Taobao, and the selection is amazing. I've never seen so many sets of the legendary Hyuga snow-grade stones in my life!
