Ai no Wakusei (愛の惑星, "Planet of Love") is the only solo album released by Japanese singer Atsushi Sakurai, lead vocalist of the rock band Buck-Tick.

Contributors include, Wayne Hussey, Robin Guthrie, Yasuyuki Okamura, and Theatre Brook frontman Taiji Sato.

[1] Atsushi Sakurai said his solo career started from Junichi Tanaka, the man who gave Buck-Tick their big break by signing them to Victor Entertainment, saying he wanted to see the singer collaborate with various other musicians.

Wayne Hussey, the composer of "Sacrifice", reused its music for the song "Running with Scissors" on the Mission's 2007 album God Is a Bullet.

[3] Sakurai toured to promote the album and a recording of his first ever solo performance at NHK Hall on July 21, 2004, was released as the home video Explosion: Ai no Wakusei Live 2004 on December 16, 2004.

[9][10] Following Sakurai's death in October 2023, Ai no Wakusei and its three singles were made available for digital purchase and streaming worldwide in December 2023.
