Japan's Studio Ghibli turns 40 this month with two Oscars and legions of fans young and old won over by its complex plots and fantastical hand-drawn animation.

But the future is uncertain, with latest hit "The Boy and the Heron" likely — but not certainly — the final feature from celebrated co-founder Hayao Miyazaki, now 84. In March, the internet was flooded with pictures in Studio Ghibli's distinctively nostalgic style after the release of OpenAI's newest image generator — raising questions over copyright.

The studio behind the Oscar-winning "Spirited Away" has become a cultural phenomenon since Miyazaki and the late Isao Takahata — he passed away in 2018 — established it in 1985. Its popularity has been fueled of late by a second Academy Award in 2024 for "The Boy and the Heron," starring Robert Pattinson, and by Netflix streaming Ghibli movies around the world.
