The MX was made in Japan.
In the very center of the camera back there is a 1 3/4” x 1 1/4” black metal frame* properly desribed as the Memo Holder. One slips the detached tab end of the film box into the frame through the top slit to remind oneself what film is loaded.
Asahi Optical Co. - Japan is engraved on the bottom border of the frame. It’s hard to see the black paint filled letters in the black metal. Edit - from memory. My MX with the black metal Memo Holder has no engraving.
* on later production models the frame was black plastic and the letters were molded in. MESuper also has the plastic version.
