Tōmei Ningen (Pink Lady song)

"Tōmei Ningen" (透明人間, meaning "Invisible Person") is the eighth single released by the Japanese female pop duo Pink Lady. Released on June 5, 1978, it became another number-one hit for the group, topping the Oricon charts for six weeks.

The song is known for its upbeat tempo, distinctive Pink Lady vocal harmonies, and a dance routine that mimicked the invisibility suggested by the title. The lyrics explore the feelings of invisibility and being ignored in a relationship. The song's success further solidified Pink Lady's status as one of the most popular and commercially successful acts in Japan during the late 1970s.

"Tōmei Ningen" was composed by Shunichi Tokura with lyrics by Yū Aku, the same songwriting team responsible for many of Pink Lady's other hits. The B-side of the single was "Pink Typhoon (Pink Typhoon)". The single sold over 1,200,000 copies.
