There have been tons of 'Let it Go' parody videos created by fans, but this one comes from a Japanese non-profit organization, the Alliance for Raising Children. The alliance is a group dedicated to supporting parents and at the same time, boosting Japan's low birth rate that's causing a significant decrease in population. The video was inspired by a lecture that discussed women who were overly stressed about becoming perfect maternal figures, and the message of 'Let it Go' seemed to fit with the message of encouraging mothers to relax and listen to their instincts.
The video replaces the icy queen Elsa with Japanese governors frolicking in capes on the beach, conjuring up teddy bears, stairs and snowflake flurries. It's pretty silly, but it's a fun way to encourage parents to keep doing what they're doing.
