Grand Blue Dreaming: Watch Order, Where to Watch & Season 4 (2026)
Grand Blue Dreaming just got a fourth season, announced on September 21, 2026, moments after the Season 3 finale aired in Japan. If the news sent you looking for a Grand Blue watch order, the good news is that it is simple: the anime is one continuous story told across three TV seasons and 36 episodes. This guide lays out that order, shows where to watch Grand Blue Dreaming season by season, and separates what is confirmed about Season 4 from what is still unknown.
Everything below is drawn from the anime's episode records and the official Season 4 announcement, with sources listed at the end.
Grand Blue watch order: all 36 episodes at a glance
There is no complicated Grand Blue watch order to memorize. Watch the three seasons in broadcast sequence, because each one picks up the story where the last left off. There are no side films or alternate cuts to slot in.
- Season 1 — 12 episodes (2018)
- Season 2 — 12 episodes (2025)
- Season 3 — 12 episodes (2026)
- Season 4 — announced September 21, 2026 (release date not set)
Akibato does not carry a dedicated Grand Blue Dreaming figure line, but if a fresh anime binge has you eyeing your next shelf piece, you can browse its Japan-import anime figures, shipped worldwide.
Where to watch Grand Blue Dreaming (streaming by season)
The one wrinkle for overseas fans is that the seasons are split across services. Season 1 originally streamed exclusively on Amazon Prime Video worldwide, while Seasons 2 and 3 stream on Crunchyroll. Because licensing shifts over time and by country, it is worth checking both platforms for Season 1 in your region.
| Season | Episodes | Aired | Where to watch |
|---|---|---|---|
| Season 1 | 12 | Jul 14 – Sep 29, 2018 | Amazon Prime Video (original release) |
| Season 2 | 12 | Jul 8 – Sep 23, 2025 | Crunchyroll |
| Season 3 | 12 | Jul 7 – Sep 22, 2026 | Crunchyroll |
The seasons stream with subtitles. A widely available English dub has not been confirmed, so check the audio options on your platform before you start.
Grand Blue vs Grand Blue Dreaming: is it the same anime?
Yes. The full title is Grand Blue Dreaming, and it is often shortened to just Grand Blue in search and on streaming pages — both refer to the same diving-club comedy based on Kenji Inoue and Kimitake Yoshioka's manga. There is no separate "Grand Blue" anime to track down.
If you see the title listed without "Dreaming," you are still in the right place. The three seasons and the newly announced fourth all belong to this one series, so any watch order you build applies to every version of the name.
Season 1 (2018): the original 12 episodes
Season 1 introduces Iori Kitahara, a fresh college student who moves to the seaside town of Izu to live above his uncle's diving shop. What he expects to be a scenic new chapter turns into life inside the Peek-a-Boo diving club, whose members mix scuba training with a great deal of drinking and comic chaos.
These 12 episodes ran from July 14 to September 29, 2018. The series was produced by studio Zero-G and directed by Shinji Takamatsu, whose comic timing sets the tone the franchise keeps for every later season. Season 1 is also the run that spent years locked to a single streaming service, which is why some longtime fans only caught up recently.
Season 2 (2025): the story continues
Grand Blue Dreaming returned after a seven-year gap with a second 12-episode season, airing from July 8 to September 23, 2025. It moves the manga's story forward rather than retelling Season 1, so watching the first season first matters here — jumping straight into Season 2 means missing how the diving club came together.
Season 2 is where the streaming home changed: this run and everything after it landed on Crunchyroll rather than Prime Video. That split is the single most common reason overseas viewers get stuck partway through the watch order.
Season 3 (2026): the Palau arc
Season 3 aired from July 7 to September 22, 2026, again in 12 episodes. Its biggest change was location: for the first time, the story moved outside Japan, taking the cast to Palau for a diving trip.
The season finale, which aired September 22, 2026, closed by setting up a new romantic rivalry around Iori — the thread the newly announced Season 4 is expected to pick up.
Grand Blue Dreaming Season 4: what is confirmed
A fourth season was announced on September 21, 2026, through the anime's official X account (@gb_anime), immediately after the Season 3 finale aired. The reveal came with a teaser visual rather than a full trailer.
Two production details are confirmed. Shinji Takamatsu returns as director, and the season is produced by studios ZERO-G and Liber. The teaser art places Iori among several of the series' women, signaling that the romantic competition around him is set to escalate.
What we do not know yet
The announcement stopped short of the details fans usually want. As of late September 2026, the following are unconfirmed:
- Release date or broadcast window
- Full staff list beyond the director
- Voice cast confirmations
- Episode count and how much of the manga it will adapt
Treat any specific Season 4 date you see elsewhere as speculation until the official account posts one.
Is there a Grand Blue Dreaming manga, and is it finished?
Yes. The anime adapts the manga written by Kenji Inoue with art by Kimitake Yoshioka, serialized in Kodansha's Good! Afternoon magazine since April 2014. It is an ongoing series, which is why the anime keeps getting new seasons to draw from.
You do not need to read the manga before watching. The anime follows it in order, so starting with Season 1 is enough to understand everything on screen.
