Imai has been the guitarist and main composer of Buck-Tick since 1983. He was also the main lyricist on their first two studio albums,
Hurry Up Mode and
Sexual XXXXX!, both released in 1987. The following year, their single "
Just One More Kiss" marked their breakthrough when it reached number six on the
Oricon Singles Chart. In January 1989, their fourth studio album
Taboo reached number one. The guitarist was given a
suspended sentence, and the band's agency was flooded with fan letters pleading for them not to disband. That autumn, they entered the studio to record their fifth studio album
Aku no Hana. When released in February 1990, it reached number one and became their best-selling album to date. They released the album
Switchblade in 1994 and were sporadically active until 1999. They reunited in 2015, and released their second album
Ultra in 2016. In 2001, Imai and Sakurai teamed up with English and German industrial musicians
Raymond Watts and
Sascha Konietzko to form the supergroup
Schwein. They released one studio album,
Schweinstein, one remix album,
Son of Schweinstein, and held a Japanese tour, all before dissolving within the year. In 2004, Imai formed the rock trio Lucy with guitarist and vocalist Kiyoshi (
Spread Beaver, Machine) and drummer Katsushige Okazaki (Age of Punk). They derived their name from Lucy Monostone, a character in the manga series
MPD Psycho. Both Imai and Kiyoshi provide guitar and vocals, and write music and lyrics for the group. They released two albums;
