A.K.A. ''Mirai Shounen Konan'' and ''Conan, The Boy In Future.'' Not to be confused with ''Manga/DetectiveConan'' (though the commonality of names was played for laughs in an AffectionateParody mashup in the ''LightNovel/FullMetalPanic'' OAV), Creator/ConanOBrien or ''Franchise/ConanTheBarbarian''.

An {{Anime}} series airing on Creator/{{NHK}} during 1978, ''Future Boy Conan'' features direction, storyboards and character designs by Creator/HayaoMiyazaki. The story is based on ''The Incredible Tide'' by Creator/AlexanderKey, also known for the ''Witch Mountain'' books.

In the far future time of July 2008, war breaks out between two great nations, using electromagnetic bombs even more powerful than nuclear weapons. This causes massive earthquakes, tidal waves, the Earth tilting off its axis, and the continents breaking apart and sinking. An attempt to escape to outer space fails, but one ship crashes on Remnant Island, which is still barely capable of sustaining life. Two of the survivors are able to have a child before they pass away.

The story proper opens with the child, Conan, now in early adolescence and living alone with his adoptive grandfather, the sole remaining survivor of the crash. They believe themselves to be the last humans on Earth. One day, a girl named Lana washes up on the shore. Conan is more befuzzled by the concept of "girl" than by her apparent ability to talk to birds. Lana is quickly followed by soldiers of Industria, one of the few remaining outposts of the old civilization.

It seems that Lana's grandfather, Dr. Lao, has disappeared, and the Industrians plan to use Lana to track him down and force Dr. Lao to return to work for them. In the ensuing fight, Conan's grandfather takes mortal injuries, and the Industrians escape with Lana. After burying his grandfather, Conan sets sail after them, despite having no idea where Industria might be.

Meanwhile, the Industrian soldier Monsley docks with the salvage ship Barracuda, and she clashes with the ship's captain Dyce before taking off to deliver her prisoner.

Conan arrives on a somewhat more populated island, and runs into another orphaned survivor, Jimsy. They soon become fast friends, and when the Barracuda docks at the island, they sneak aboard to head to Industria to rescue Lana.

Which does happen, but not before many more exciting adventures have happened.

* BadassAdorable: Conan.
* BelligerentSexualTension: Monsley and Captain Dyce.
* BetaCouple: Monsley and Captain Dyce.
* BigBad: Lepka.

* CharlesAtlasSuperpower: Conan's vigorous life on Remnant Island has made him superhumanly strong for his size and able to cling to surfaces with his toes.
* CompetenceZone: Set to age 11. Until they're older than about 60, the adults are less competent and in many cases ''physically weaker'' than the young heroes.
* CoolPlane: Falco. Giganto is not so much "cool" as just freaking huge.
* DefeatMeansFriendship: Actually, it's more like a Tie Means Friendship between Conan and Jimsy.
* DoesNotLikeShoes: Conan was practically raised barefoot, so he feels more comfortable like so. When the people at High Harbor try to give him shoes, he gets rid of them fast, though it doesn't help that they're too large for him.
* DownerBeginning: The story starts with [[spoiler:the death of Conan's adoptive grandfather and last survivor of the ship crash.]]
* [[spoiler:DrivenToSuicide: The doctors of Industria, they decided to let themselves die during the sinking of the island]].

* EvilTowerOfOminousness: The Industria tower serves as this.
* [[ExpressiveHair Expressive Mustache]]: Dyce's.
* FreeRangeChildren: Justified, as throughout the series, the heroes' parents are either dead, incapacitated, or missing. But even when Conan had a guardian, he was able to go shark-hunting with no real attempts to stop him.

* GaiasRevenge: Land-sinking earthquakes occur in urbanized areas. [[spoiler:Eventually one of these sinks Industria.]]
* GentleGiant: "Patch".
* GhibliHills: High Harbour, which could pass for a coastal Mediterranean town if not for the occasional bits of ruined highway still standing.
* GoodScarsEvilScars: "Patch" has a nasty scar vertically across his left eye (which wears the black patch he's nicknamed for) and back across his skull, which makes him look very scary. But he's actually very kind, [[spoiler:being in fact the missing Dr. Lao]].
* GoodSmokingEvilSmoking: Jimsy seems to have a tobacco addiction.
* GreenAesop: Even green energies like solar energy won't save you if you abuse the planet too much. You need to live by only taking what you truly need.
* HeelFaceTurn: Monsley and Captain Dyce.
* ImperialStormtrooperMarksmanshipAcademy: Industrian shooters NEVER hit anything, not even when their target is at near point blank (see episode 18 at the start, when Conan rescues Lana).
* IntergenerationalFriendship: Conan, Lana and Jimsy with Dyce and Monsley.
* KidHero: Conan, natch.
* NoOneCouldSurviveThat: Lepka's damaged escape craft explodes--behind a nearby hill. Everyone assumes that's the end of him, but there's still three episodes to go.
* NoSocialSkills: Jimsy, and to an extent Conan as well, in High Harbor.
* OceanPunk: Thanks to the massive war involving magnetic weapons, many of the habitable areas happened to be islands that can only be traversed by ships.
* OlympicSwimmer: Conan is a terrific swimmer and can hold his breath far longer than normal for even a trained human being (in episode 9, he's stated to have stayed underwater for three and a half minutes).

** [[ShipTease Implied]] with Jimsy and Tera.
* ReusedCharacterDesign: Several characters will look ''very'' familiar if you've seen other works of Miyazaki.
* RidiculouslyCuteCritter: The pigs that Jimsy raises are remarkably soft-looking.
* ScavengerWorld: There's a plastic shortage, so the islanders dig through old trash heaps for the stuff.
* {{Tsundere}}: Monsley reacts violently whenever Dyce compliments her.
* VestigialEmpire: It's mentioned that Industria was a major world power before the apocalypse. By the time the series takes place however, what's left of the country is just teetering on the brink.
* UnfortunateNames: Jimsy, when you're raising a pig, you're ''not'' supposed to call it "Tasty".
