A recent study from Teikoku Databank reveals a concerning trend in Japan’s mobile gaming sector, with bankruptcies among game developers and publishers experiencing a significant surge. Between January and July 2026, ten companies specializing in mobile games filed for bankruptcy, a stark contrast to the three recorded throughout the entirety of 2025. At this rate, industry experts predict that 2026 could witness the highest annual number of bankruptcies in the sector since 2015, when twelve mobile game studios collapsed.
This alarming trend follows a particularly contentious bankruptcy case. In late July, Tokyo-based studio Ambition, the developer behind the long-running live-service title Bungo Stray Dogs: Tales of the Lost, unexpectedly announced the game’s closure mere hours later. The company also declared it would not issue refunds for unused virtual currency and purchases, sparking widespread criticism. It was subsequently confirmed that Ambition had filed for bankruptcy concurrently with the shutdown announcement.
Developers are facing mounting challenges in crafting and maintaining successful mobile games, even those leveraging popular intellectual properties and substantial marketing efforts. Teikoku Databank attributes this struggle to the escalating demands of the genre, including advanced 3D visuals and full voiceovers, alongside a persistent domestic talent shortage that drives development costs into the hundreds of millions of yen.
Sustaining post-launch operations presents another hurdle, as the continuous creation of fresh content proves expensive and difficult to maintain, especially with diminishing player engagement. The report also highlights intense competition from high-budget mobile hits originating in China and South Korea, whose production values and scale many Japanese developers find challenging to replicate under current industry circumstances.
