10musume-073110 01 Instant

I might search for common associations with that code. "10musume" sounds like it could be part of a Japanese idol group name. "10musume" might translate to "Ten Girls" or be the name of a group. Checking online... There's a Japanese idol group called "10musme" (JUJU), which was active in the 80s. So maybe "10musume-073110 01" refers to a release related to them?
