Could anyone help me to find a song?

Hi there!
I've just joined this forum with the hope that someone could help me with the attached song.
It's a song I heard during my Christmas holidays in Japan. It was being played at a coffee shop in Kyoto. Sadly I was only able to record the last seconds with my camera, so i'm afraid the sound quality isn't very good and the playing time is too short. Sorry!
I would thank it very much if anybody could recognize what song it is, and if she/he was kind to tell me its name. I know it's not an easy task!
Thank you all in advance. Best regards!
