The little girl playing an instrument. She's on top of the sign for Tokorozawa ENT Clinic, the local otorhinolaryngologist.
The Tokorozawa ENT (which I found out stood for Ear, Nose, and Throat) Clinic was founded in 1977. The sign itself is very unique. I didn't realize it was a clinic until I went to see the otorhinolaryngologist there one day.
