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.
