burapan

Japanese equivalent to Wigger; it's the emulation of black culture in Japan. "The name given to the fashion sensibilities of all black wannabes"

Burapan is a combination of the Japanese phonetic of "black" (burakku) and the Japanese word for "prostitute" (pansuke), a prostitute that whores herself out to black men.

So basically, the same could be said for Japanese people who immerse themselves in Black American culture.
