I attended the local militaria show this past Saturday, and found a Japanese
medal at one of the tables. It is a Japanese ‘Order Of The Sacred Treasure’.
I’ve been looking for one of these ‘higher grade’ enameled medals for
a while, and stumbled across this nice 5th Class version.

It came in a lacquered box with gold kanji on the lid. It is missing the lapel
rosette - no worries. 5th Class medals in pure silver have gilt inner rays
at the 3, 6, 9 and 12 o’clock positions. The reverse of this medal has
a small ‘M’ stamped on the lower arm - Osaka mint ?

I’m not sure exactly what period it is from, but I’ve read that earlier
pieces have rivets on the back………
