This one has stumped me. Unfortunately this is a favor for a "friend of a friend" and as such I do not have the coin to give specific technical details and the image is less than crisp.
Estimated diameter ~35mm
Possible translations: The box - "Eighty years of the birth of Hi Majesty the Emperor"
Reverse: Rim - "Lower 10 years of clothing"??, "Emperor of Japan", "Japanese law"
Suspected to be gold plated.
Any ideas?
