Dr. STONE Season 4 Is Not on Netflix: Where All 37 Episodes Stream

For four seasons, Senku had one permanent advantage: he knew things nobody else knew. Season 4 takes it away. The man waiting on the other side of the Pacific runs his own kingdom of science, built the same way, from nothing, and he spent his previous life inside a national space program. Knowing more is no longer the win condition.

These 24 episodes are the first two cours of Dr. STONE: SCIENCE FUTURE, the final season. Before anything else, one practical warning for American viewers: if you have been watching this show on Netflix, it stops for you here.

📺 Where to Watch Dr. STONE Season 4: Science Future (October 2026)

Service	Status	Notes
Crunchyroll	Streaming	All 37 episodes of the final season, subtitled plus English dub
Crunchyroll Amazon Channel	Add-on	Paid Crunchyroll channel on top of Prime. Not included with Prime
Amazon Prime Video	Rent / Buy	Episodes sold individually. No subscription offer
Netflix	Not available	Netflix US carries Seasons 1–3 and stops there
Hulu	Not available	Season 1 only
Disney+	Not available	Streams on Disney+ in Japan, not in the US
HBO Max	Not available	No offer

Crunchyroll is the only US subscription carrying the final season (listed directly or through its Amazon channel), and it has every episode through the ending, subtitled and dubbed. Everything else fell away one season at a time: Hulu stopped after Season 1, Netflix stopped after Season 3. If you met this show on Netflix and wondered why the story simply ended in the middle of an ocean voyage, nothing is wrong with your account. The license just never went further.

Coming in cold? Season 1 is where the stone world and the war with Tsukasa begin, and New World is the 22 episodes immediately before this one. Season 4 opens mid-voyage with a crew you are expected to already know.

🔢 How Many Episodes Is Dr. STONE Season 4, and Is There a Season 5?

Season 4 runs 37 episodes, and there is no Season 5. Science Future was announced as the fourth and final season in December 2023, at the end of New World, and its own final episode went out in Japan on June 25, 2026. Each episode is about 24 minutes, so the season comes to roughly fifteen hours.

It was broadcast in three parts, which is why the episode numbering confuses people. Part 1 is episodes 1 to 12 (January to March 2025). Part 2 is episodes 13 to 24 (July to September 2025). Part 3 is episodes 25 to 37 (April to June 2026). This review covers Parts 1 and 2. US streaming listings file all 37 under a single Season 4.

If I were starting now, I would not repeat the way Japan had to watch it. We waited six months for Part 3 to follow Part 2, and the hand-off in episodes 22 to 24 that I describe below leads straight into Part 3, so go from episode 24 to 25 without a break if you can. After episode 37 there is nothing more: the anime finishes at 94 episodes over four seasons, plus the 2022 Ryusui special, and no sequel has been announced.

🎬 Trailer

This is the Japanese broadcast trailer from TOHO animation. Every English trailer Crunchyroll cut for this season refuses to play from Japan, which leaves me unable to vouch for them. This one I can stand behind.

📖 Synopsis - No Spoilers

The Kingdom of Science sails for the Americas, chasing the source of the signal that turned every human being on Earth to stone. What they find on the far shore is not wilderness. It is a second scientific civilization, already standing, run by Dr. Xeno, a former NASA scientist who woke from the same petrification and made the same decision Senku did.

Both sides want the petrification device. Both sides can build. The difference is that Xeno has a marksman named Stanley standing next to him and several decades of hardware advantage, while Senku has a crew of villagers with spears. Walking into a firefight is not an option, so the season becomes something else: a contest over what the science gets pointed at.

✨ What Makes It Special

When both sides know the formula, the formula stops mattering

Every previous antagonist in this show was outside the discipline. Tsukasa brought muscle to an argument about chemistry. Ibara brought paranoia. Senku always had one card nobody could answer, which was simply knowing how the world works.

Xeno answers it. He knows the same reactions, follows the same procedures, and has run a real laboratory with a real budget. The show could have resolved that by making one of them slightly cleverer, and it declines to. What separates them is where their inventions point. Xeno’s work bends toward weapons. Senku’s keeps branching into food, clothing, entertainment — things that look like waste until the moment they decide an encounter. That is the whole argument of the season, and it never gets stated out loud.

The definition of winning quietly changes

Somewhere in the second cour, the Kingdom of Science stops trying to defeat anybody. The goal shifts to keeping one person alive and handing off what they know. Hunted, hiding, losing people and equipment, still passing the minimum forward.

Rewriting the victory condition is what saves this stretch from feeling like filler. Not being wiped out becomes progress in itself, so each escape carries weight instead of postponing the real story. It is an unusual structure for a shonen series, which normally has to escalate to stay alive.

Science stops belonging to the smartest person in the room

This is the part that got me. Since episode one, the science in this show has been Senku’s property. He knew, he instructed, everyone else supplied muscle and steady hands. Late in these 24 episodes, that arrangement breaks. The story is handed to the member of the crew furthest from any laboratory.

What it demonstrates is reproducibility, which is the entire difference between science and magic. If the procedure was transmitted correctly, the person who was taught can produce the same result. Stated flatly it sounds obvious. Watched as a scene, on top of 24 episodes of buildup, it does not.

🎭 Memorable Scenes

The loudest the show has ever been: two aircraft, built from scratch by two groups of stranded people, fighting over the sky of a world where civilization stopped 3,700 years ago. Watching that, it is hard to remember this started with a boy cracking rocks to make fire.

The best written hour is episode 5, “DOCTOR VS. DOCTOR.” Xeno and Senku read each other, then account for being read, then act on that. Physical strength is irrelevant for the length of the episode, which is the clearest statement of what this season is for.

And then episodes 22 through 24, which is where the handover happens. Who receives what is worth discovering unspoiled. If you have seen people describe the second cour as back-loaded, five minutes of those episodes explains why.

💭 How It Made Me Feel

Unsettled, mostly, and I think that was intended. Ibara was a man you could enjoy seeing lose. Xeno is not, and Stanley — who does truly terrible things — operates by a code he never breaks. Winning against people like that does not produce a clean feeling afterward. The show pays for its own honesty here, and I would rather it did.

The craft sequences still work, too, though not in the same way as the early seasons. That distinction turns out to matter, so it belongs in the next section rather than this one.

😅 Where It Falls Short

The builds got too advanced to show you

The pleasure of this series was always watching a thing get made: gather the material, follow the steps, hold up the result. What Season 4 builds cannot be shown that way without stalling the picture, so completion gets compressed. The sense of having built it alongside them thins out.

It reads less like a mistake than like a side effect of the civilization advancing. It is still a loss if that was your reason for watching.

Two cours, not much forward motion

Split it up and these 24 episodes are a long chase with Stanley and a long chess match with Xeno. Individually the incidents work. Measured end to end, the plot is close to where it started. That is a real deduction, and I am not going to argue it away.

Revival fluid keeps draining the stakes

Since Season 3, petrification can undo a fatal injury. I wrote about this in the New World review and the situation has not changed. The problem is structural rather than emotional: when someone can be brought back, a suicide run is always available, so the things being risked keep shrinking even as the danger on screen escalates.

📺 Streaming Guide by Service

Which US subscription should you use for Science Future?

There is no decision to make. Crunchyroll is the only service in the US with a subscription offer on this season, and it has all 37 episodes with both subtitles and a dub. The Amazon route exists in two forms and both cost extra: the Crunchyroll channel bolted onto Prime, or buying episodes outright. If you already pay for Crunchyroll, you are done.

🎬 If You Loved Science Future, Watch These 3 Next

Bakuman Season 1

If what you like about Dr. STONE is watching a procedure produce a result, this is the same pleasure with pens instead of reagents. Two teenagers learn the craft of making manga one technique at a time, against deadlines, inside an industry that keeps score. It excites you with the work rather than the finished thing, which is structurally the same trick, and it stays dry-eyed about it.

Ranking of Kings

A protagonist who cannot win by force, finding another route. More to the point for this season: the people opposing him have reasons you end up understanding. If refusing to flatten Xeno and Stanley into villains is what worked for you here, this show does the same thing and hurts more with it. The picture-book art is not a warning that the story will be gentle.

The Promised Neverland Season 1

Children against an adult who is smarter than they are, in a game where a single mistake is fatal. The reason it belongs next to Season 4 is that the opponent never gets stupid so the heroes can advance — the exact quality that makes the Xeno chapters work. It is also the tighter show, since twelve episodes cannot afford a long chase.

📝 Final Thoughts

These 24 episodes put two scientific civilizations in the same room and decline to resolve it by intelligence. What separates Senku from Xeno is what each of them decided the knowledge was for, and the show trusts you to notice without being told. The cost is that the plot barely advances across two cours, and the builds you came for get compressed. Both complaints are fair.

Then the last three episodes arrive and reframe the whole stretch. Something gets handed to someone who was never supposed to carry it, and the 24 episodes that felt like a holding pattern turn out to have been building toward exactly that. The final cour closes the series 13 episodes later. That voyage across the Pacific is a big part of why Dr. STONE heads our best adventure anime list.
