Where would I get metal engraved?

Hi, I’m looking to get some metal engraved—nothing fancy, only a little bigger than a pen. Does anyone know what sort of place I could get this done? Where I’m from, you can get this done in most shoe repair/key duplication shops. Not sure if the same goes here. I’m in Yokohama, so I’d really appreciate it if anyone from here knows a specific spot. Thanks!
