Translating Japanese medals

[Jonah]

My Great Grandfather was in World War 2 and brought back coins and medals when he returned. Since he has passed away I have inherited one medal I cannot recognize or read and was wondering if someone would be willing to translate it for me!

大東亜戦争記念

In Commemoration of the Greater East Asia War

I doubt it was anything officially issued by the government.

Thank you for the help!
