In Japan, department stores are upmarket sort of a place.

However, one of major department store franchise in Japan - Isetan - decided to portray a more fun and easy-going image of their brand. So they gathered around 500 of its staff to create a music video.

Filmed in the actual department store, the staff cheerfully dance in front of the camera. The original music is written by Akiko Yano, and the dance is choreographed by MIKIKO, who also choreographs a well-known Japanese pop girl group Perfume.
