is the tenth single by Japanese band Princess Princess. Written by Kanako Nakayama and Kaori Okui, the single was released by Sony Records on November 21, 1990. It became their fourth of five consecutive No. 1 singles on Oricon's singles chart.
"Julian" was Princess Princess' first ballad single. While the title is a reference to the band's former name , lead guitarist Kanako Nakayama named the song after her pet cat, which was given to her by Bow Wow lead vocalist Kyoji Yamamoto. Julian had lived with the band at their training camp in Nishi-Nippori, but shortly after the band left the training camp, he ran away and was never seen again. Despite the title, the song is not about Nakayama's cat, but a former lover of hers.
The song's original key is C.
The song was used by Citizen for their Lighthouse watch commercials. The B-side, "Rock Me", was used by Sony for their cassette tape commercials.
"Julian" hit No. 1 on Oricon's singles chart and No. 13 on Oricon's year-ending chart in 1991. It also sold over 588,000 copies and was certified Platinum by the RIAJ.
All music is composed by Kaori Okui and arranged by Princess Princess.
