Jun Seba (瀬葉 淳, Seba Jun, February 7, 1974 – February 26, 2010), born in the Nishi-Azabu district of Minato, was a Japanese record producer, DJ, composer and arranger who recorded under the stage name Nujabes (ヌジャベス, Nujabesu). Nujabes (pronounced /ˈnudʒɑːbɛs/) was an anagram of his name, being the reverse spelling of Seba Jun. He was the owner of two Shibuya record stores, T Records and Guinness Records, and founder of the independent label Hydeout Productions. His style mixes hip hop and jazz samples. Nujabes collaborated with other Japanese artists such as Uyama Hiroto, Shing02 (with whom he created the critically acclaimed "Luv(sic)" hexalogy), and Minmi, and was also involved with America's underground hip hop scene through collaboration with CYNE, Apani B, Five Deez, Substantial, CL Smooth, Fat Jon, and Terry Callier. In his career, he released three studio albums (Metaphorical Music in 2003, Modal Soul in 2005, and Spiritual State, released posthumously in 2011) and two collection compilations (Hydeout Productions 1st Collection in 2003 and 2nd Collection in 2007). One of his most recognizable works is that of the background music for Shinichirō Watanabe's series Samurai Champloo (Music Record: Departure and Impression) in 2004.

On February 26, 2010, Jun Seba died in a traffic collision. Following his death, numerous tributes were made by other artists from around the world (including his own label Hydeout Productions).
