Nakayama Maruichi Hoyama (Asagi?)
I just picked this one up and received it yesterday. I don't know much about it but I am going to lap it and see how it works this weekend. Stamps are the Maruichi stamps but no Maruka. The stone is very blue-green in person with red sides which is why I say "Asagi?" in the title of the thread. One end of the stone is a bright orange on the top surface while the rest of the surface is a bright blue green, much brighter in person than in the photos.
There is a "Razor use" stamp on this stone the Nihon Kamisori stamp.
