It’s an ever growing list, please send me your experiences and I will add them in. These are just off the top of my head, am sure I will remember more.
Local supermarket in Yoyogi, Tokyo – Grant Green & Sonny Clark
Liquor Store near Takadanobaba station, Tokyo – Thelonious Monk
Dentist’s Office in Yotsuya, Tokyo – Ella Fitzgerald, Blossom Dearie (USEN Jazz Vocals station I think)
Fruit Store in Koto Ward, Tokyo – sounded like Bill Evans, very likely as he is a deity in Japan.
Chiropractor (整骨院) in Ooguchi, Yokohama – USEN Soul Jazz station, always so groovy. Changed recently to a Roots Reggae station.
Airport Lounge, Fukuoka – sounded like Dexter Gordon, couldn’t be sure.
Tiny corner store in SeijoGakuen-Mae – Old guy there had on some swinging big band music.
Fresh Fish restaurant in Matsuyama City, Shikoku – swinging hard-bop as the BGM. Sounded like Horace Silver but not sure.

Numerous Hotel lobbies
