Id help needed: Brass ? porcelain plate

Any info to id this brass porcelain wall plate is much appreciated.

Who made it, when, where...
who is the man?
Does the brass decoration have a special name?

Incl brass 30 cm diametre

 

I think this is one of those Japanese oddities. They made some classical portrait plates like this in the early post war years (you find some with Made in Occupied Japan stamps). Some are mounted in neo-classical/renaissance style embossed brass mounts like yours. I had a batch a while ago and it took me quite a time to find out what they were.

 

Thanks @Ce BCA. I have a few 20 century japanese porcelain but they looks different. On the others i dont see glaze imperfections like these and the bottom looks also different
