this looks extremely similar to the chilean "100 peso" coin https://en.numista.com/catalogue/pieces2302.html
I thought this was just kind of old but not that shocking until I realized... you probably aren't physically in Japan?
I’m in Canada! You don’t see random Japanese coins around here all that often… or at all
