"Renai Circulation" (Japanese: 恋愛サーキュレーション, Hepburn: Ren'ai Sākyurēshon, lit. "Love Circulation") is a song from the 2009 Japanese anime television series Bakemonogatari (the animated adaptation of the first book from the Monogatari series by Nisio Isin) and performed by Kana Hanazawa as her character, Nadeko Sengoku. Composed by Satoru Kōsaki with lyrics written by Meg Rock, "Renai Circulation" serves as both Nadeko's character image song as well as the opening theme song in episode 10 of Bakemonogatari, which first premiered on September 11, 2009, to represent the "Nadeko Snake" story arc.
"Renai Circulation" was released on digital services and as a limited edition CD bonus with vol. 4 of the DVD and Blu-ray home releases of Bakemonogatari on January 27, 2010. It was later given a wider physical release and compiled on the series' soundtrack album, Bakemonogatari Ongaku Zenshū Songs & Soundtracks on December 21, 2011.
"Renai Circulation" received praise for its "cute" melody as well as Hanazawa's vocals. After the initial release of "Renai Circulation", in 2010, the song inspired a trend of cover dances and mash-ups on Niconico. In the late 2010s, the popularity of the song resurfaced again, this time globally, through TikTok.
