Japan has one of the world’s most distinctive radio cultures. Its public broadcaster is one of the oldest in Asia; its commercial radio market created a genre — J-pop — that has become a global phenomenon; and its radio format reflects a national culture that values precision, presentation, and craft in broadcasting that other countries rarely match.
NHK: Japan’s public broadcaster
NHK (Nippon Hoso Kyokai) has been Japan’s public broadcaster since 1926. Its radio division runs NHK Radio 1 (news and general programming), NHK Radio 2 (educational content), and NHK FM (music and culture). NHK World Radio Japan also broadcasts internationally in 17 languages — one of the few remaining shortwave international broadcasting operations of significance. NHK’s production standards, particularly for classical and traditional music programming, are internationally respected.
J-pop and its radio presence
J-pop (Japanese pop music) is a catch-all for the mainstream Japanese popular music industry. It is distinct from Western pop in several ways: the idol culture (manufactured solo artists and groups, particularly girl groups and boy bands), the link between music and anime/gaming soundtracks, and the industry’s resistance to international streaming until relatively recently. Commercial FM stations in Tokyo, Osaka, and other cities carry J-pop alongside Western pop — J-WAVE in Tokyo is a prestige station known for its international music programming; NACK5 and Bay FM serve the Kanto area.
City pop: J-pop’s global rediscovery
City pop, a style of smooth, sophisticated J-pop from the late 1970s and 1980s (associated with artists like Tatsuro Yamashita and Mariya Takeuchi), experienced an extraordinary global revival from around 2017, driven by YouTube algorithm serendipity and later by TikTok. Dedicated city pop radio stations appeared online to serve the international audience. It is a rare case of a historical Japanese domestic music format finding a large global internet audience decades after its original popularity.
