"Taishō Roman" (大正浪漫, alternatively titled "Romance")[1] is a song by Japanese duo Yoasobi from their second EP, The Book 2 (2021).

[5] On August 9, 2021, at YouTube live streaming, Online Live Viewing Event "Yoasobi Hanseikai", the duo announced to adapt the award-winning story Taishō Romance to produce a song, titled "Taishō Roman", with changing a word from "Romance" (ロマンス) in katakana to "Roman" (浪漫) in kanji instead of the original on September 15, and publish the book of the same new title on the following day, September 16.

[8] The English version, titled "Romance", appeared on the duo's second English-language EP E-Side 2, released on November 18, 2022.

"[11] Lyrically, like the based novel, "Taishō Roman" tells a time-lapse romance of two people who span over a hundred years.

[20] The duo released a teaser video of the song on September 13, showing Ikura's voice reading passages from the based novel Taishō Romance.

[7] For the music video, the characters were designed by Eisaku Kubonouchi, Shinji Kimura was the art director,[20] and collaborated with NTT Docomo's project Quadratic Playground.

Finally, the pair runs towards each other and embraces, but as quickly, the music video ended up with Chiyoko fading from an explosion of light.

[23] Yoasobi performed "Taishō Roman" for the first time, alongside "Loveletter", and "Tsubame" at NHK's music show Songs on December 2, 2021.
