Ponyo

The Ponyo watch order is a single Studio Ghibli film — there is no series, sequel, or OVA to watch, just the standalone 2008 movie. As a self-contained feature, Ponyo requires no viewing sequence at all: press play and enjoy the complete story in one sitting. Made under the Ghibli banner, it stands entirely on its own with no connected entries to track down, so there is no chronological-versus-release question to answer. Anyone asking where to start and finish has a simple answer — the movie is both. For a watchlist, log Ponyo as one film and check it off in a single evening. If you are working through Studio Ghibli's catalog, this fantasy adventure slots in wherever you like, since nothing in it depends on having seen the studio's other movies first.
