Hi folks,
I got this hone a little while ago, and the chap I got it from said the markings indicated it was a Nakayama Asagi. Whether that is true or not I am looking for help on. In any case it is a nice finisher - hard, but not super hard like my big gray brick (Ozuku) and leaves a nice edge. I'm not sure how the colors will look on your monitor, but the stone is a olivey green/gray color.
I've included images of the original stampings and box, if anyone can help with an ID I would be most appreciative.
