The flight attendants of Japan Airlines (JAL) put on their best idol costumes to dance to Hatsune Miku’s “39” (San-kyuu, or ‘Thank You’) song to promote the company’s participation at the Niconico Chokaigi 2015 event this month.

The video shows the dancers in various spots within the JAL Sky Museum in Tokyo. In the background you can see how the attendant’s uniforms have changed throughout time.

JAL will have a “flight simulator” and a stepcar photo opportunity at Niconico Chokaigi 2015 with flight attendant cosplayers.

Niconico Chokaigi 2015 will take place at Makuhari Messe International Exhibition Center in Chiba on April 25 and 26.
