[Japanese(?) > English] inside body cavity of guitar

This symbol was under the pickguard of a guitar I am restoring. It's an Aria, which is a Japanese company. They've outsourced some of their production to China and Korea in later years, but I don't see a date or serial number anywhere on the instrument. It doesn't look like Korean to me, but Google Lens was no help on deciphering it. Maybe it's a signature or something? I dunno. It looks cool, though 🤷‍♂️
