Broadcast radio has maintained its reach and listening time over the past decade: younger people listen less than before, but this is made up for by an ageing population.

The challenges to radio come from changes in distribution technology in the home and in cars, and from product innovation in the online audio space.

Over the next few years, we predict continued stability in radio, but as technology brings it into closer competition with online audio, broadcasters will have to continue product innovation.

Recorded music revenues in Japan are stuck in decline as physical sales sag, although 2017 marks the first year when streaming gained a foothold with 8 million subscribers. 

J-pop fans spend on 'experiences' with their idols including events, merchandise, CDs and DVDs, which streaming cannot replicate. Top native LINE MUSIC offers integration with a popular messaging app and bundling with mobile. 

Serving international repertoire, Apple Music claims more subscribers than Spotify in Japan, which is more localised, and has most users on the free tier. Amazon Prime Music is a looming constraint on the adoption of subscriptions.
