Jay Love Japan is an instrumental album by the late J Dilla distributed to retail by the California-based Operation Unknown label most recently on March 7, 2008. Promo and semi-official retail versions of the album have circulated for several years, and the album was even given a 2006 release in Japan, although that version is now considered a promotional item. It was announced in an issue of the magazine Wax Poetics in 2005 and given various missed release dates in 2006, 2007, and 2008, with a track list containing two songs with other artists' vocals added after Dilla's death. The official status of this release remains unresolved at this time despite the fact that some web sites and stores sell the album.

The album is shrouded in mystery and, if rumors of Operation Unknown's improprieties are to be believed, deceit. J Dilla began and possibly completed this album before his death in February 2006. Some say that the album was intended as an instrumental EP featuring two guest vocal tracks, whereas the label itself first described it as featuring Raekwon, Blu, Ta'Raach, Truth Hurts, and more, tentatively including Slum Village. A bootleg version of the album leaked without Raekwon's vocals in mid-2006. Dilla's manager said in a 2005 interview that this was one of two albums completed for planned release the following year, the year of Dilla's death. The album has an accompanying video series for the track "Can't You See." Most recent photographs used of J Dilla, such as the inside cover of J Dilla's BBE album The Shining, as well as recent MTV pictures, were Operation Unknown photo sessions for Jay Love Japan. An EPK was released as far back as 2005.
