Tsuchida, a recent graduate, is starting his first job as a kindergarten teacher at Hanamaru Kindergarten. On his way to school, he runs into a little girl named Anzu who thinks that Tsuchida is hitting on her. While this is not the case, it's only later he finds out that Anzu is the daughter of Sakura, a girl he knew in high school. Anzu is taking the flirting thing very seriously, saying that she intends to become Tsuchida's wife. Her mother is completely fine with the idea.

The series focuses on the day to day adventures of Anzu and her friends, Hiiragi and Koume, as well as the rest of the class and teachers at Hanamaru Kindergarten.

Based on the manga by Yuto and produced by {{Gainax}}, the series aired in the winter 2009/2010 season.
----
!Tropes in ''Hanamaru Kindergarten'' include:
* AllLovingHero: Yamamoto-sensei is a shining beacon of light and goodness, if [[ObliviousToLove a bit oblivious in some areas]].
* ArtShift: ''[[http://manga.animea.net/hanamaru-youchien-chapter-1-page-10.html This]]'' is the first look we get at the girls in the manga, a very deliberate attempt to make the readers think this will be a serious romance/drama in the vein of ''Kodomo No Jikan''. Then on the next page we get a [[http://manga.animea.net/hanamaru-youchien-chapter-1-page-11.html better look at them]].
** Episode 11's ending is animated in a notably different style from the rest of the show. Episode 8's is as well, using a watercolor style.
* AttentionDeficitOohShiny: The girls' attempt to follow Tsuchida around in episode 5 is marred by Koume and Anzu constantly getting distracted.
* AuthorAvatar: The octopus the anime uses for scene transitions turn out to be Yuto himself.
* BigBrotherWorship: Satsuki definitely shows signs.
* BlandNameProduct: Hiiragi's mind thinks in terms of the "Coojle" search engine.
* CatSmile: Anzu
* ComedicUnderwearExposure: 'Koume's underwear is white!'
* CosplayFanArt: The second end card features Hiiragi dressed as [[TengenToppaGurrenLagann Yoko]].

* CreditsJukebox
* CuteBookworm : Hiiragi
* CuteButCacophonic: Aoi, when she shows off her fishmongering skills in class.
* CuteLittleFangs: Aoi
* ADayInTheLimelight: The second half of episode 3 focuses on Yamamoto-sensei. The first half of episode eight also brings Aoi, one of the girls' classmates, into the spotlight.
* DiggingYourselfDeeper: Tsuchida's attempts to explain away Anzu's behavior just gets him even further in a rut.
* [[ActorAllusion Director Allusion]]: The references to the [[Anime/FullmetalAlchemist 2003 anime adaptation]] of ''Manga/FullmetalAlchemist'' and ''ShamanKing'' were likely because Seiji Mizushima directed all three anime.
* EveryoneCanSeeIt: Even kindergarteners.
* FestivalEpisode
* FreeRangeChildren: Averted for the most part, since the kids are usually seen in school and, thus, supervised by their teachers. Also specifically averted in the episode where the girls follow Tsuchida around on a Sunday afternoon and Sakura follows them.
* {{Gainaxing}}: Yamamoto in her swimsuit [[spoiler:and the grown-up Anzu from the dream]]. [[{{Trope Namer}}Although Gainaxing in a Gainax produced show seems redundant, somehow.]]
* GagSub
* GenerationXerox: Anzu is practically a miniature version of Sakura, in personality and apprearance, with a different hairstyle, as [[BreakingTheFourthWall Tsuchida points out to the audience in an aside monologue.]]
** She inherits the front half of her hair from her mother and the back from her father.
* GenkiGirl: Anzu ''and'' her mom Sakura.
* HaremSeeker: While he's only focused on Yamamoto, Tsuchida had dreams of having an entire ''harem'' of teachers after him. Whether he has that in the present is debatable.
** Tsuchida is still talking about it to his sister just before his first day, albeit as a joke, in the manga.
** Kusano is apparently grooming her students so they will grow up "macho". Hmm...
* HeadPet: Anzu frequently becomes one for Tsuchida (as in, she scampers up him and sits atop his head). It's adorable.
* HeyItsThatVoice: Yamamoto-sensei is what happens when [[Manga/{{ARIA}} Akari Mizunashi]] became a kindergarten teacher minus the [[CloudCuckooLander absent-mindedness]].
** And [[ShakuganNoShana Tsuchida]]-[[LightNovel/ZeroNoTsukaima sensei]] [[Creator/SatoshiHino too]].
** [[KojiYusa Hanamaru-sensei]] used to be [[Series/KamenRiderDenO a lot better with women]]...
* HopelessSuitor: [[spoiler:Kusano to Tsuchida starting chapter 85.]]
* HotBlooded: Kusano-sensei
* HotForStudent: Not just Anzu to Tsuchida (which her mother approves), but Anzu's mother, Sakura, is married to her high school art teacher.
* IdiotHair: Anzu and her mother, Sakura
* InnocentProdigy: Hiiragi. Able to read complex books yet her eyes will sparkle in joy at going down a slide.
* InstantAwesomeJustAddMecha: In Tsuchida's puppet show that closes off the series, his fairy tale suddenly gains a HumongousMecha.
* InVinoVeritas: Tsuchida, after downing a bar's worth of booze, confesses to Yamamoto. But even a drunk Yamamoto is oblivious.
* [[spoiler:IWantMyBelovedToBeHappy: Anzu, to Tsuchida, in episode 12.]]
** Anzu, again, and most of the kids [[spoiler:at the end of the manga, when they make Tsuchida confess his love to Yamamoto.]]
* JailBaitWait: Inverted with Anzu and Hinagiku having to wait until they're old enough to marry Tsuchida without him being [[{{Squick}} squicked]].
* KissingCousins: Daichi, [[spoiler:Yamato's cousin, tries to start a relationship with her in chapter 83.]]
* LateForSchool: Tsuchida is, the first episode. And yes, he meets an important member of the opposite sex.
* LawyerFriendlyCameo: In a brief cut in episode 3, what is quite clearly [[Manga/KOn Yui and Azu-nyan]] can be seen.
* {{Leitmotif}}: Instrumentals of the ending songs can sometimes be heard for their respective character.
* LethalChef: Anzu's still young, but her first attempt at cooking barely qualifies as food.
** She gets much better by episode 11 though.
* LongDistanceRelationship: [[spoiler:Yamamoto and Tsuchida]]
* LoveConfession: [[spoiler:A few ones nearing the end:]]
** [[spoiler:Hanamaru-sensei goes for it in chapter 92.]]
** [[spoiler:Kusano confess to Tsuchida in chapter 97.]]
** [[spoiler:and Tsuchida finally spits it out in chapter 101 after being cornered by the kids.]]
* LoveEpiphany: [[spoiler:Yamamoto when she thinks Mayumi and Tsuchida are a couple.]]
* LoveTriangle: [[InvokedTrope Outright explained]] by Hiiragi in episode 3.
* LoveDodecahedron: As the series progresses relationships get more fleshed out and new love interests are added.
* LoveYouAndEverybody: Yamamoto says this once in episode 3. Mercifully it was to Anzu, not Tsuchi.
* MafiaPrincess: Hinagiku
* MarshmallowHell: Tsuchida gets a bit of this when Yamamoto-sensei hugs him in episode 3. Wouldn't be Gainax if they didn't include this...
* MeaningfulEcho: Repeated three times in the course of one half-episode. Tsuchida's speech on ThePowerOfLove inspired Sakura, who in turn repeated it to Anzu, who repeated it to Tsuchida himself.
* MeaningfulName: Yamamoto Nanako's name is an anagram/pun of YamatoNadeshiko, the ideal Japanese woman she embodies.
* MediumBlending: Episode nine's ending is largely live action, though the family photos of the Yamamoto sisters are animated.
* MistakenForPedophile: Poor Tsuchida.
* MostWritersAreWriters: Hanamaru-sensei.
* MulticoloredHair: Anzu's hair is blonde in the front and brown in the back, naturally.
* NiceGirl: Yamamoto-sensei yet again.
* NoMouth: Hiiragi
* NoNameGiven: Just about everybody.

* NoSenseOfDirection: The Yamamoto girls' parents.
* NotSoAboveItAll: When Hiiragi's Panda Cat costume is commented on, she breaks into the ShowWithinAShow's dance. [[http://i50.tinypic.com/2vjbd5i.jpg D'awwww!]]
* ObliviousToLove: Yamamoto is completely unable to realize that anyone is attracted to her. This fact is [[LampshadeHanging lampshaded]] to hell and back in episode 3. This runs in the family, apparently, as Mayumi is no less oblivious about Hanamaru's attraction to her. Ironically, each of the sisters is fully aware of the other's situation, and they both feel sorry for the man in question.
* [[spoiler:OfficialCouple: Mayumi/Hanamaru-sensei]] and [[spoiler:Yamato and Tsuchida in a LastMinuteHookup]]
* OnTheNext: The next episode preview is given by a character or group of characters that changes for every episode. At the end of the preview, the characters giving it will ask the next group to do it next time.

** Likewise in the manga.

* PinkySwear: Anzu and Yamamoto have one of these in episode 4.
* PoolEpisode: The first half of episode six. Includes a wardrobe malfunction from Yamamoto-sensei.
* PrecociousCrush: Anzu to Tsuchida, obviously.
* PreMeeting: Tsuchida meets Anzu for the first time on the way to his first day at work, when he sees her alone on the side of the road. He addresses her and "Ojou-chan" - essentially "Miss" or "little lady" - and she jumps to the conclusion that he's hitting on her. Of course, he's her teacher, and the [[HilarityEnsues misunderstanding persists]].
* PuniPlush: Forget MarshmallowHell, the kindergartners ''are marshmallows''.
* {{Recycled IN SPACE}}: The second ending theme (they change every week) recasts the show as ''Space Hanamaru Kindergarten''.
* RuleOfCute: The lifeblood of this anime/manga.
* SenpaiKohai: Sakura and Tsuchida, respectively.
* SheIsAllGrownUp: Anzu makes a wish to Santa to become an adult. [[AllJustADream Her wish]] [[BlatantLies is granted.]]
* SheIsNotMyGirlfriend: For as much as Tsuchida would like her to be, he has to explain that he and Yamamoto aren't like that when his mother asks the question.
* ShoutOut: The last frame of Episode 2 has the three main toddlers in a pose reminiscent of ''GurrenLagann'''s Simon, Kamina, and Yoko... and Hii is wearing Yoko's signature outfit.
** In episode 4, Tsuchida and Anzu ride a toy version of [[Anime/NeonGenesisEvangelion Misato's car]].
** When Hiiragi's explaining the things that could happen to Yuu in episode 5, she lists off the [[Anime/NeonGenesisEvangelion Second Impact]] and the [[Manga/FullmetalAlchemist Ishval War]].
*** In the manga, she mentions [[GundamSEED the Bloody Valentine War]] instead of the Ishval War.
*** ...as well as the possibility of [[TwentiethCenturyBoys breaking up with 'Friend']].
** When the girls follow Tsuchida around in episode 5, they all dress as DetectiveConan.
*** The capsule machine the girls see Tsuchida buying figurines from sells Anime/NeonGenesisEvangelion merchandise.
** Hiiragi's space dreams include ''Franchise/PlanetOfTheApes'', the ''[[Franchise/StarTrek USS Enterprise]]'', Series/{{Ultraman}}, Film/ETTheExtraterrestrial and a fight with [[Franchise/StarWars Darth Vader]].
*** There was also an appearance of what seem to be a [[TabletopGame/{{Warhammer 40000}} Battle Barge]]!
** When the teachers go to sing karaoke in episode 10, one of them is singing "Northern Lights" from ''ShamanKing''.
** Also in episode 10, most of the things that nearly kill Anzu in the ending are shout outs from various horror movies.
** As befits a manga published by (and an anime sponsored by) Square Enix, Tsuchida often plays [[DragonQuest Dragon Quest IX]] on his DS.
** At the end of the second special, Anzu [[NeonGenesisEvangelion promises more fanservice]].
* ShowWithinAShow: ''Panda Cat''
** Complete with EarWorm [[http://www.youtube.com/watch?v=ckJc2qazNkU theme song.]]
* ShrinkingViolet: Koume
* SliceOfLife
* SoundtrackDissonance: Episode 10's ending. The music is a serene piece about something Tsuchida forgot. The animation is Anzu being sent through a wide awake nightmare, and ends with Yamamoto being a vampire.
* StrawberryShorthand: Anzu, reflecting on the difficulty of love while eating a strawberry.
* SuperDeformed: Semi-justified in that although the children are basically toddlers, this is what their proportions come across as onscreen compared to the adults, moreso than RealLife.
* ThemeNaming: Most of the young girls have botanical names: Anzu = apricot, Hiiragi = holly olive, Koume = small plum, Hinagiku = daisy, Aoi = mallow.
* ThisLoserIsYou: There's an element of this with Tsuchida.
* ThroughHisStomach: Anzu attempts to invoke this in Episode Three by making Tsuchida [[LethalChef some... sort of... curry-like substance.]] [[CaptainObvious It fails.]]
* TooMuchInformation: Played straight, during an episode where the kids are drawing their dreams. Anzu's dream is obvious (marrying Tsuchida), which stays innocent until a certain line is delivered...
--> '''Tsuchida''': Are we getting naked as soon as I get home?
--> '''Anzu''': My parents are like this all the time!
--> '''Tsuchida''' (with an appropriate expression): Eh? Sakura-senpai? and sensei?
* TotemPoleTrench: In the fourth ending, "Yamamoto" turns out to be Anzu, Hiiragi and Koume standing on top of each other.
* {{Tsundere}}: Tsuchida's sister, Satsuki
* UnEntendre: See Anzu's misunderstanding in PreMeeting above.
* UnwantedHarem: Played with. Before starting his job Tsuchida fantasizes about having a whole school worth of teachers after him. He does end up with multiple characters wanting to marry him. They're all kindergartners.
* WackyHomeroom
* WiseBeyondTheirYears: Hiiragi, who's pretty smart for a kindergartener.
--> ''[[{{HSQ}} "The trajectory calculations for the comet have been completed, Daddy!!" ]]''
** Somehow one of the kids knows what forbidden love is.
* {{Yakuza}}: Hinagiku's father is the head of one, though he's rather nice. [[spoiler:and Hinagiku's more in control of the "family" than he is.]]
* YamatoNadeshiko: Yamamoto-sensei. Hinagiku claims she will become one (using the exact phrase.)
