Japanese jazz is jazz played by Japanese musicians, jazz connected to Japan or Japanese culture, or both. The term often refers to the history of jazz in Japan, which has the largest proportion of jazz fans in the world, according to some estimates.

Jazz kissa, sometimes transliterated as jazu kissa, are cafés that specialise in the playing and appreciation of recorded jazz music. Unique to Japan, jazz kissa are spaces where jazz music is played for dedicated listening rather than as background music. A typical jazz kissa features a high-quality stereo system, a large music collection and dim lighting, and serves coffee and alcoholic drinks.
