The Dexter Thomas Jr. Collection of Japanese Hip Hop is a collection of nearly 600 items, in both Japanese and English, on Hip Hop culture in Japan that Thomas compiled over several years while conducting research in this area. The collection primarily consists of compact disc recordings from Japanese Hip Hop artists, but also includes manga, magazines, and other materials pertaining to Japanese Hip Hop culture.
Thomas, an accomplished scholar on Hip Hop and African American Studies in Japan, is a UCR graduate and former Director of Programming at KUCR 88.3 FM. In 2014, he spent a year abroad in Japan as a visiting Fulbright Scholar at Waseda University and in recent years has written for the Los Angeles Times and served as a correspondent for HBO's Vice News.
Thomas donated the collection to the UCR Library in 2014.
