U.S. Ambassador Caroline Kennedy and other embassy staff across Japan made a splash on social media Tuesday by releasing a Christmassy, U.S. Embassy version of a koi (falling in love) dance routine aired in a popular Japanese TV drama series.

The 90-second clip uploaded Tuesday evening on YouTube features Kennedy in a Santa Claus outfit and others donning reindeer caps dancing in sync with "Koi," a theme song of the TV drama "Nigeru wa Hajidaga Yaku ni Tatsu" (roughly translated as "Running Away is Shameful but Useful").

The video, copied from one aired at the end of each episode of the drama series, had been viewed nearly a million times on the video-sharing site as of Wednesday afternoon.
