 Coldplay released "Lovers in Japan" in the United States on 3 November 2008 as the fourth single from Viva la Vida or Death and All His Friends. A new mix of the song is also featured in the band's 2008 EP Prospekt's March, entitled "Lovers in Japan (Osaka Sun Mix)". Chris Martin said of the Prospekt's March version of the song: "We've been playing it live better than it is on the record. So the live version has informed this Osaka Sun version, which is just a bit more lively."
