Bright LEDs embedded in the skirt light up a girls thighs, particularly the “absolute territory” (zettai ryouiki), a term used by Japanese to refer to the exposed skin area between the top of knee high socks and hemline of a skirt, according to a report by Rocket News 24.

Assisted by gyro sensors, the LEDs in the skirt is capable of changing a wide range of colors depending on user movement.

Gyro sensors attached to the skirt enables the skirt to change a variety of colors and patterns in accordance to the users’ movements, according to Tokyo Girl’s Update report.

The “absolute territory” is especially sexually appealing to a group of Japanese men known as otakus that are defined by their obsessive interest in anime or manga fandom and social recluse, according to a UDN report.

The thigh region where the skin shows between the knee high socks and skrt hemline or known as "absolute territory" in Japanese is considered sexually attractive.

Amano, who designed a similar prototype skirt that can be used as a fashion or cosplay item last year, received massive funding from otakus to release the Hikaru skirt, the report added.

The skirt is expected to be mass produced this year, but further details about the skirts pricing or LEDs used are currently unavailable.
