The single's title is a mixture of the Japanese word mottainai, usually meaning wasteful but precious here, and the phrase Night Land.

The song was first used on the latest au commercial aired in October, featuring Kyary dancing with the Mottainai Ghosts.

The regular edition will be themed with "Wasteful Fantasy", depicting Kyary transforming into an animal while surrounded with fruits and vegetables.

The limited edition version will have an "Incredible Fantasy" theme, which has Kyary wearing a wig with apple and orange skins, showing off its "Mottainai" nature.

"[4] The Fader wrote of the video, "“Mottai Night Land” is a tour de force, featuring a catchy hook, a dance with the moon, an anime segment and oiled-up bikini dancers.
