Adolescent Sex is the first album by the English band Japan, released in March 1978 by record label Hansa. To avoid controversy over the title, the album was renamed simply as Japan in some countries.
Though not a commercial success in their native UK, the album was better received abroad, particularly in Japan itself, where it peaked at No. 20, and in the Netherlands where the single "Adolescent Sex" reached number 27 in the Dutch Top 40 in 1979.
The Japanese release contained several mistranslations of song titles. "Transmission" became "Invitation to Fascination", "Suburban Love" became "Carousel of Love", and "Television" became "Temptation Screen".
Within a couple of years of its release, the band publicly denounced the album.
"The band were not totally happy with the first album or the way it had been marketed, and were dismayed by its poor reception in the UK. Their record company were not that ecstatic with the British sales either and required another album, this time aimed at the lucrative US and European markets."
Trouser Press wrote that the album "introduces Japan in all its guitar-rock misery, playing such Bowie-influenced tripe as "Wish You Were Black" with less style than a sense of urgency".AllMusic gave the album a 4.5 out of 5 grade, writing: "A more exciting album than just about anything else they'd ever record, Japan were young, hungry, and more than a little rough around the edges."
