Of the many things for which Kumamoto Prefecture (home of Mellow Monk tea) is famous, one of the "big three" is said to be the traditional song and dance "Otemoyan" ("Little Miss Otemo").
(The other two of the big three are Mt. Aso and Suizenji Park.)
Below are a couple of clips of the song performed in Japanese films.
Here's actress Chiemi Eri singing a version of the song in the film "Orishidori Senryogasa."
Here's a more modern version of the song, from "Seishun Kouro." I believe this is Chiemi Eri again.
