Grand Blue Dreaming Season 4 Announced With New Visual

Grand Blue Dreaming is officially moving forward with Season 4. The anime's official website confirmed the new season on Sept. 22 in Japan and released a production announcement visual centered on Iori Kitahara and the series' increasingly tangled romantic rivalry.

What the Season 4 announcement confirms

The new visual is the centerpiece of the announcement. The production team says it is designed to suggest that the battle surrounding Iori's love life will intensify in the coming season. That framing points toward the romantic complications left around the cast, while preserving the comedy's familiar focus on Iori and the chaos that follows him.

The notice itself is brief, but its wording is direct: Season 4 is in production. The visual serves as its first official promotional image and gives the continuation an immediate story hook.

The announcement does not give a premiere window, episode count, staff lineup, broadcaster list, or streaming plan. The official team says later updates will be posted through the anime's website and social account, making those announcements the next place to expect concrete information about when and how the season will arrive.

For viewers finishing Season 3, the confirmation removes the largest immediate uncertainty about whether the television adaptation will continue. The visual also gives the announcement a story-facing focus rather than simply presenting a logo, teasing a more heated contest around Iori without laying out specific plot developments or identifying how the rivalry will unfold.

Where Grand Blue Dreaming stands

Grand Blue Dreaming follows Iori as he moves to a seaside town for university and begins staying at GRAND BLUE, the diving shop operated by his uncle. He arrives expecting clear water, an idyllic campus life, and time with a childhood friend. Instead, he is pulled into a rowdy all-male diving club and its relentless parties. His university friend Kohei Imamura soon becomes part of the same mayhem.

The anime adapts the manga written by Kenji Inoue and illustrated by Kimitake Yoshioka, which is serialized in Kodansha's good! Afternoon magazine. The manga has passed 11 million copies in circulation, giving the property a substantial readership beyond the television adaptation.

The wider franchise began its television anime run in 2018, received a live-action film in 2020, and has also been adapted for the stage. Those versions place the newly announced season within a property that has already moved through several formats while remaining anchored to the original manga's coming-of-age diving comedy.

Season 4 extends that screen history and gives viewers a clear continuation point after the third television season rather than leaving the adaptation's future open. Its initial promotional material emphasizes relationships around Iori, matching the premise's balance of college life, diving, friendship, and unruly comedy.

For now, the confirmed package consists of Season 4's production and its first visual. The next concrete milestone will be a follow-up from the official anime channels, which are set to reveal further information as it becomes available.
