Gaming Market: Japan Mobile Game Revenue Tops $10B Despite Download Decline
Japan's mobile gaming market generated over $10 billion in in-app purchase revenue over the past 12 months, a 5.1% year-over-year decline, yet significantly outpacing South Korea and Taiwan. According to Sensor Tower's Japan Gaming 2026 report, downloads fell 5.4% to 585 million, ranking ninth in Asia. Player engagement remained stable at 16.7 billion hours. Konami's eFootball became the highest-grossing game, driven by World Cup activities, while Block Blast! led downloads. Puzzle games dominated downloads, while 4X strategy led revenue growth. The market's maturity is evident, with growth reliant on established titles and high spending rather than new installs.
Relevant to mobile gaming and ad monetization, but it's a market report with no direct AdTech impact.
