In the following musical collage of 1974 composed by Franco Battiato (the name of the song is "Ethika fon ethica"):

there are several traditional songs in the album "Music Of The World's Peoples (Volume One)" of 1951.

However I found from the moment 3:15 to the moment 3:25 an oriental song for female voice not present in that album, it's probably a traditional Japanese song and maybe the piano part was overlaid later. Can someone please identify the song?

Thank you
