Japan is certainly no stranger to viral dance videos and one doesn't have to think too far back to recall the popularity of the koi (falling in love) dance routine that took the internet by storm last year.
Popularized by TV drama "Nigeru wa Hajidaga Yaku ni Tatsu" (roughly translated as "Running Away is Shameful but Useful"), the quirky routine even prompted employees at U.S. government agencies in Japan to air their own winter holiday version featuring then-U.S. Ambassador Caroline Kennedy.
While such viral dance routines are nothing new, internet users have recently shown a fondness for videos that tap into cross-generational influences.
