[[caption-width:250:Hello! Project's logo.]]

Hello! Project is an umbrella term to refer to the [[AlwaysFemale female idols]] managed by Up-Front Agency and Tsunku. Major groups in the Project are Morning Musume (the flagship and longest running group), C-ute, ANGERME (formerly S/mileage), Juice=Juice, Country Girls, and Kobushi Factory, with former Morning Musume member Aika Mitsui as its sole current soloist. There are also numerous sub-units and Hello! Pro Kenshuusei (formerly Hello! Pro Egg), a training program for young girls looking to become full-fledged idols under the Project. Each group has their own unique sound and members, with no two songs sounding the same.

The current line up's ages range from 10 to 24, with every kind of girl you could think of. A lot of them also do things outside of singing, such as acting, hosting TV shows, etc.

See the [[Characters/HelloProject character sheet]] for who's who, or [[http://en.wikipedia.org/wiki/Hello!_Project That Other Wiki]] for more information.

---------
'''Hello! Project provides examples of:'''

* AcCENTUponTheWrongSylLABle: Linlin, although she's Chinese.
* AdultsDressedAsChildren: One of the old Hello! Morning segments, although in most cases it was more teenagers dressed as nursery school kids.
* AnimalReactionShot: The "Dramatic Chipmunk" clip was taken from a [[http://www.youtube.com/watch?v=p4KS9qzEi8A TV segment]] of Mini Moni and a prairie dog.
* AlbumFiller.
* AllJustADream: The videos for "Kono Chikyuu no Heiwa wo Honki de Negatterun da yo!" and "Kare to Issho ni Omise ga Shitai!"
* AlohaHawaii: The Alo-Hello! [=DVD=]s.
* AlwaysFemale: They are a female idol group after all.
* AllOfTheOtherReindeer: Morning Musume member Aika Mitsui stated that at first, she felt rather lonely as nobody talked to her.
* AnAesop: Mini Moni were put together to show "small people can do big things".
* AntiLoveSong: Many. "Kanashimi Twilight" is probably the best known example.
* AnimatedMusicVideo: Some of Mini Moni's [=PVs=], and Morning Musume's "Yah! Ashitai" (under the pseudonym Lili Moni.)
* [[AttackOfThe50FootWhatever Attack of the 50-Foot Idol]]: The PV for "Love Machine" by Morning Musume; hilariously, one of the people who is shown this size is Mari Yaguchi, who is sometimes referred to as "the short one".
** The video for "Kare to Issho ni Omise ga Shitai!" also had this with Risa Niigaki fighting a Godzilla {{expy}}, apparently with ThePowerOfLove.
* AudienceParticipationSong: Morning Musume's "Aozora ga Itsumademo Tsuzuku You na Mirai de Are!" amongst others.
* AuthorityInNameOnly: The Leaders and especially Sub-Leaders of groups sometimes act as peacekeepers if there's a falling out between members of their group and on game show appearances they may pick who competes if appropriate. However they are just The FaceOfTheBand, if that, in regards to the actual music.
* AwesomeButImpractical: Became an EnforcedTrope a few times when Ayaka had her "Chinese cafe" gimmick for her English lessons segment on ''Hello Morning''; she wore a tight Chinese style dress which looked great, but she couldn't dance properly in it when asked by Ai Takahashi or Nozomi Tsuji. Her attempts to do so anyway when bullied into it by the latter are SugarWiki/{{Funny Moments}}.
* AwesomeMomentOfCrowning: When the Elder Club graduated Yuko Nakazawa, the very first leader of Morning Musume, passed on Leadership of Hello!Project to Ai Takahashi.
** Morning Musume winning the Japanese Record Award for Best New Artist.
* BadassAdorable: Asami Konno is a black belt in Karate.
** Rika Ishikawa once broke 12 concrete tiles with a single blow from her bare hands! Sure, it turned out they were especially designed to break, but when Ai Takahashi tried to do the same thing on another show she [[EpicFail failed miserably]] until she resorted to stamping on the stack instead.
* BadBoss: When ever a favourite member graduates suddenly or a [[TheScrappy unpopular girl]] is hired a certain section of the [[FanDumb fans]] usually accuses Tsunku since he is the person directly responsible for Hello Project (though he still answers to the [[TheManBehindTheMan company president]]).
* BareYourMidriff
* BavarianFireDrill: Used as a prank on Morning Musume during an episode of Utaban (they faked an actual fire with smoke and alarms going off). This leads in to what is effectively a PublicServiceAnnouncement to make sure they and the viewer [[AndKnowingIsHalfTheBattle know what to do]] in the event of an earthquake or other disaster.
* BeachEpisode: The making of [=DVDs=] for the girls' photobooks.
* BewareTheNiceOnes: Again, Asami Konno has a black belt in Karate.
** Played closer to the trope description with Mari Yaguchi and Takashi Okamura, with the latter repeatedly pushing the former's BerserkButton and getting an ArmourPiercingSlap for it.
* {{Bifauxnen}}: Hitomi Yoshizawa (she was at one point, at least) and Haruka Kudo.
* BigEater: Nozomi Tsuji and Ai Kago were pretty notorious examples when they were younger.
--> '''Nozomi:''' It's our role to eat the food, isn't it?
* BitchInSheepsClothing: Rika Ishikawa's Charmy character would quite often act like this, though it is a case of MeanCharacterNiceActor.
* BlatantLies: In "Joshi Kashimashi Monogatari", Ai Takahashi denies still having her Fukui accent... ''in Fukui-ben''.
* BookDumb: Several of them; most notably, Nozomi Tsuji came dead last in one of the school test segments.
* BreakTheCutie: Poor, ''poor'' Ai Kago...
* BrutalHonesty: Reina Tanaka has [[http://www.youtube.com/watch?v=uwHkf65A6eI her moments.]]
** [=JunJun=] was pretty well known as being a straight talker, especially compared to Japanese norms of etiquette.
** Sayumi Michishige's "poison-tongue" character shows shades of this sometimes.
* ButWeUsedACondom: Nozomi Tsuji announced her pregnancy in May 2007. In one of the interviews, she said "we used a condom, but it broke."
* CallBack: In the original "Joshi Kashimashi Monogatari" and one of the Elder Club versions, Mari Yaguchi's part refers to the lyrics of "Koi no Dance Site".
* TheCastShowoff: Ayaka Kimura and Mika Todd; due to the fact Ayaka spent a large part of her childhood in Hawaii and Mika is an American, both of them are fluent in English as well as Japanese, and both were given many opportunities to speak English in songs and on TV shows (Ayaka even hosted a "corner" on Hello Morning specifically due to this). Whenever Mini Moni were on Utaban, Mika would usually tell them whatever news she had by impersonating a news report in English before translating it into Japanese.
** Ai Takahashi and Kaori Iida are both excellent dancers and were afforded many opportunities to do so outside of the usual [=PVs=], concerts and TV performances.
* CatchPhrase: So, SO many.
** "USO!" (Koharu Kusumi, Risa Niigaki)
** "Usa-chan peace~!"/"Yoshi! Kyou mo kawaii!" (Sayumi Michishige)
** "Bacchiri desu~", "W desu!" (W)
** "SEXY BEEEEEAAAAAM!" (Mari Yaguchi)
** "Mayuge BEEEEAAAAAM!" (Risa Niigaki)
** "HAAAAPPPYYYYY~"/"Gucha~"(Rika Ishikawa)
** "Yurushite nyan!" (Momoko Tsugunaga)
** [[http://www.youtube.com/watch?v=rploMAHUhkE "Matsuuuuura Aya deeeesu!"]] ([[CaptainObvious Aya Matsuura]] - it's the delivery more than the actual words that are notable in this case)
** "Ganbatte Ikuta!" (Erina Ikuta)
** Riho Sayashi had "Hyahho~i!" for a while (to the point where it was the name of one of her [=DVDs=]!) until she got tired of it.
* [[CantHoldHisLiquor Can't Hold Her Liquor]]: Kaori Iida, according to a parody version of "Love Machine" she did alongside Kei Yasuda.
* CharactersAsDevice: Chinese members Junjun and Linlin who only joined to break into the Chinese market.
** Before them, Coconuts Musume was an attempt to do the same thing for the US.
* CoolBigSis: Most of the old-school Morning Musume members.
* CoolOldLady: Yuko Nakazawa. Okay, so she's not that old but there is a significant age difference compared to some other former members: for instance, she is about 13 years older than Ai Kago.
* CoverVersion: Morning Musume's ''Chokkan 2'' single was originally an album track with a slightly different name. Producer Tsunku has covered various H!P songs. A lot of cover versions also appear as b-sides and album tracks. Not to mention the FOLK SONGS and Douyou Pops series...
** "Joshi Kashimashi Monogatari" has had about 7 covers using the same music and chorus, but entirely rewritten verses in each version.
** Eri Kamei and Risa Niigaki both released solo albums comprised entirely of them covering HP songs.
** On the other end of the spectrum, Koharu Kusumi's "[[http://www.youtube.com/watch?v=ZBuDK88vWWw Koi kana]]" becomes Laura Vanamo's "[[http://www.youtube.com/watch?v=FMjZHGBJgmk Se tunne]]". That's not Japanese, that's Finnish!
** Singles that have been covers include:
*** Natsumi Abe: "The Stress", "Too Far Away ~Onna no Kokoro~".
*** Berryz Koubou: "Dschinghis Khan". Yes, ''that'' "Music/DschinghisKhan".
*** C-ute: "Shochuu Omimai Moshiagemasu"
*** Aya Matsuura: "Watarasebashi", the ''Naked Songs'' album.
*** Melon Kinenbi: "Namida no Taiyou".
*** Morning Musume: "Morning Musume no Hyokkori Hyoutanjima", "Pepper Keibu", the ''Cover You'' album.
*** W: Actually, most of their discography.
*** S/mileage: Between "Shortcut" and "Samui ne", they have released a cover of an old H!P song as a b-side.
*** Viyuden: "Nanni mo Iwazu ni I LOVE YOU".
** During Aya Matsuura's 2 Alo-Hello [=DVD=]s she does an "Aloha" acoustic version (with a ukulele accompaniment) of one of her songs, though neither song was ever actually released as a CD.
*** In the drama ''Brementown Musicians'', Mika Todd and Nozomi Tsuji both sing versions of a song called "Kasa ga Nai".
* CrazyCulturalComparison: [[AlohaHawaii Coconuts Musume]] was formed and marketed as the group from Hawaii. Jun Jun and Lin Lin joined Morning Musume for much the same reason, except they were aimed at the mainland Asian market.
* CrosscastRole: Happened a lot during ''Hello Morning Theatre'' skits due to the fact the cast was made entirely of girls, particularly to Yossey.
** Also happened in several [=PVs=].
* TheCutie: They're idols, so all of them are either cute or beautiful, but Michishige Sayumi probably fits the actual description of the trope the best.
** Rika Ishikawa also played this trope too on and off -- mainly on -- especially when she was younger. It may be argued that Ishikawa (as Charmy) and Michishige are actually {{Kawaiiko}} and just think they're TheCutie.
*** Ai Takahashi, particularly in the segments of ''Haro Pro News'' where she dressed up in cute costumes like as a CatGirl, which caused either a CutenessProximity or, in for masculine costumes such as a [[BadassBiker biker]], a HoYay reaction in co-host Yuko Nakazawa that sometime led to her seeming to be DistractedByTheSexy, and jealousy from Supercaster Charmy Ishikawa.
*** Ai Kago, especially as she went on to suffer a BreakTheCutie that took her a few years to come back from.
*** Saki Nakajima
* DarkerAndEdgier: One of Hitomi Yoshizawa and Rika Ishikawa's post-Musume projects was a Punk Lolita styled JRock group called Hangry & Angry, which was VERY dark compared to their work in Morning Musume. However, it wasn't actually a part of Hello Project, but they were still under the Up Front Works banner.
* ADayInTheLimelight: Asami Konno and Sayumi Michishige were only leads for one single, "Namida ga Tomaranai Houkago". This has happened with other members, too.
** "Oh my wish!" is this for Kanon Suzuki and Haruka Kudo. Suzuki's case in this is notable, as it came after the controversy from her not appearing in the [=MVs=] for the previous single (due to an injured foot -- she was replaced by Karin Miyamoto of [=Juice=Juice=], who got more screentime than any other member.)
* DeadpanSnarker: Kaori Iida, though sometimes she doesn't get the deadpan part right. She's also [[TallDarkAndSnarky rather tall]] and well qualified as a PungeonMaster.
** Yuko Nakazawa could also be very snarky.
* DistractedByMyOwnSexy: According to Miki Fujimoto, among others, her [[VitriolicBestBuds best friend]] Aya Matsuura would quite often be distracted during conversations if she saw herself in a mirror or on a monitor. Aya admitted to it at least once.
-->'''Natsumi Abe:''' You seem like the type of person that likes looking in mirrors.
-->'''Aya:''' [[SelfDeprecation Yes, I love it.]]
* EccentricMentor: Producer Tsunku, arguably. He's either that, a TrollingCreator, or just simply crazy.
* EvolvingMusic: The [[UpToEleven many MANY]] versions of "Joshi Kashimashi Monogatari".
* FamilyFeud: Kago's family.
* {{Fanservice}}: Photobooks which consist mainly of bikini shots.
** Also the [[FanserviceWithASmile cafe versions]] of Ayaka's English lessons.
** "Love Machine" probably sets some kind of record for sheer density of fetishes.
* FetishFuel: [[InvokedTrope Invoked]] by Kaori Iida when she sees Ayaka Kimura wearing her Chinese dress for the first time.
-->'''Kaori:''' (after Ayaka has explained why she's wearing the dress) "I see, that's Okazumi's (the producer) fetish, right?"
* FootballFightSong: Morning Musume's "Ganbare Nippon Soccer Fight!"
** [[FootballFightSong Baseball Fight Song]]: C-ute's "Koero! Rakuten Eagles", DEF DIVA's "LET'S GO Rakuten Eagles" and GAM's "Daisuki Rakuten Eagles".
* FourGirlEnsemble: 4KIDS, Akagumi 4, Athena & Robbikerottsu, Country Musume ni Ishikawa Rika, DEF DIVA, Elegies, Melon Kinenbi, Mini Moni, Puripuri Pink, Sheki Dol, ShugoChara Egg!, Taiyou & Ciscomoon and Tanpopo 2nd gen, S/mileage before the addition of the submembers.
* ForeignCussWord: On an episode of ''Hello! Morning'', Morning Musume member Ai Takahashi said "oh sh** ", followed by "I want a kitty".
* FunWithAcronyms:
** GAM ('G'reat 'A'ya 'M'iki)
** Gomattou ('Go'to Maki 'Mat'suura Aya and Fuji'moto' Miki (''moto'' can also be read as ''tou''.))
** SI☆NA ('S'uma, 'I'washima, 'N'akayama, 'A'be)
** Nochiura Natsumi ('Go'to Maki (''go'' can be read as ''nochi''), Matsu'ura' Aya, Abe 'Natsumi')
** HI-FIN (Mai '''H'''agiwara, Erina '''I'''kuta, Kanon '''F'''ukuda, Ayumi '''I'''shida, Saki '''N'''akajima)
* FunWithForeignLanguages: Engrish galore! There are others as well.
** Explored thoroughly with Coconuts Musume, as well as its two bilingual members Mika and Ayaka teaching random English phrases to other H!P singers. If the member in question was Ai Kago, Mari Yaguchi or Nozomi Tsuji, then HilarityEnsues.
*** An episode of ''Sanma No Manma'' featuring Morning Musume turned into a discussion of what animals are called in Chinese.
--> '''Sanma''' What do you call cows in China?
--> '''Jun Jun''' Niu.
--> '''Sanma''' And horses?
--> '''Jun Jun and Lin Lin''' [[SugarWiki/FunnyMoments MA!]]
* GameShowAppearance: Satoda Mai and Yaguchi Mari. Frequently.
* GamerChick: Ai Takahashi (who has been seen with a pink - natch - Nintendo DS in at least one episode of ''Hello! Morning''), Sayumi Michishige (whose proficiency at ''VideoGame/{{Tetris}}'' is listed among her special skills), and Chisato Okai (who has made blog posts about playing video games).
** Mari Yaguchi has done an advertising campaign for Nintendo's Wii and DS, and also had a regular column in ''Famitsu'' magazine.
*** When they were having a tournament on VideoGame/DanceDanceRevolution most of the girls were scoring in the tens of thousands, except for the famously unathletic Ai Kago who [[CurbStompBattle won her round with a score in the millions]].
**** Haruna Iikubo enjoys Nintendo games.
* GenkiGirl: Quite a few. Makoto Ogawa 's status as one is even [[LampshadeHanging lampshaded]] in the first version of "Joshi Kashimashi Monogatari".
* GenreBusting: Although lyrically there is a tendency towards ballads, SillyLoveSongs or [[AntiLoveSong breakup songs]], the styles of music have been as diverse as big band ("Mr. Moonlight ~ Ai No Big Band" by Morning Musume), rap ("Get Up! Rapper" by Salt 5)[[note]]Well, it was an attempt at rap, but it ended up sounding more like dancehall[[/note]] and pop punk ("Aoi Sports Car no Otoko" by Aoiro 7)
* GirlGroup
* GirlishPigtails: Several members have sported them over the years, particularly when they were younger, but Sayumi Michshige has had them consistently through her run in Morning Musume.
* GreatestHitsAlbum: Morning Musume has ''four''. Berryz Koubou had three, C-ute has one, then there are the Mega Bests and yearly Pucchi Bests...
* GratuitousEnglish: Lin Lin's "HI! BYE!" t-shirt in the video for "3,2,1 Breaking Out" is just the tip of the AsianSpeekeeEngrish-filled iceberg.
* GroinAttack: On an episode of ''Utaban'' featuring Mini Moni, [[http://www.youtube.com/watch?v=GX7DCKarbiI Ai Kago suddenly used one against Mari Yaguchi]] while simultaneously [[AssShove punching her in the backside]].
* HardDrinkingPartyGirl: There have been several instances where Kei Yasuda and especially Yuko Nakazawa are accused of being like this, usually met with an angry protest from Yuko.
-->'''Yuko''': You've never seen me like that!
* HiddenDepths: (though not well): Kaori Iida is a published poet and has had paintings exhibited.
** Natsumi Abe is interested in politics.
** [[RuleOfThree Asami Konno is a black belt in Karate]].
** [=LinLin=] plays guitar.
* HilariousOuttakes: [=GakiKame=]'s (Risa Niigaki and Eri Kamei) outtakes of their skits on ''Haromoni@''.
* HotterAndSexier: Morning Musume's "Egao YES Nude", and then there is the PV for "[[LesYay Melodies]]" by GAM.
** The lyrics for "Kimagure Princess".
** Berryz Koubou's "Ai no Dangan", "Aa, Yo ga Akeru" and "ROCK Erotic".
** S/mileage's "Mystery Night!"
* HurricaneOfPuns: Where to begin...
* HypocriticalHumour: In the original version of "Joshi Kashimashi Monogatari}, Ai Takahashi denies still having a Fukui accent... [[BlatantLies in Fukui dialect]].
* IdenticalStranger: [=RuRu=] of T&C Bomber and Ai Kago of Morning Musume look very alike, though usually the former is said to look like an older version of the latter, and more recent pictures of Kago really show that claim to be quite accurate.
* IdolSinger: Well...
* [[ChildrenAreInnocent Idols Are Innocent]]: ...is what the management would LIKE you to think.
** Averted by several songs such as "Kimagure Princess" and "Egao Yes Nude".
* ImprobableHairstyle: Masae Ohtani.
* InnocentInnuendo: The fans twist everything.
* InnocentFanserviceGirl: Sayumi can act like this, but she knows what she's doing.
* IntentionallyAwkwardTitle: 99% of the names of EVERYTHING. ''Barely'' avoided with "Brainstorming", which very nearly saw release under the abbreviated name "Buresuto" (say it out loud.)
* IntergenerationalFriendship: Some of the older members are friends with the younger ones. Sayumi Michishige is the most prime example, especially when she became the sole 6th gen member amongst the rest of the younger girls.
* JapanesePopMusic
* {{Jerkass}}: Miki Fujimoto and Yuko Nakazawa.
** Takashi Okamura probably deserves a mention here too. Though obviously not a member, much of the comedy from segments he did alongside H!P members comes from his acting like a {{Jerkass}}, espcially towards Mari Yaguchi but [[ArmorPiercingSlap she didn't always let him get away with it]].
* KansaiRegionalAccent: Yuko Nakazawa, Aika Mitsui and Ai Kago amongst others.
* KimonoFanservice: In the New Year shows, the girls all wear kimonos.
* LastChorusSlowDown
* LoopedLyrics
* MeddlingParents: Apparently some parents didn't want their daughters to become idols.
* {{Meganekko}}: H!P Egg Manami Arai and Melon Kinenbi member Megumi Murata used to wear glasses just for show.
** Miki Fujimoto wears glasses; seemingly they are reading glasses as she doesn't have them on all the time, but they appear in the PV for "Joshi Kashimashi Monogatari".
** In the PV for "Love Machine" all the members are seen wearing glasses. It's also a fairly overt example of {{Fanservice}}, along with most other images in the PV. In the Studio PV for "Love Machine", Kei Yasuda is wearing reading glasses.
** In ''Until the Bus Comes'', characters played by [[{{Dojikko}} Natsumi]] [[BadassBookworm Abe]] and [[ScrewPolitenessImASenior Kei Yasuda]] wear glasses. Yuko Nakazawa sometimes wore them for her [[HotTeacher sexy teacher character]], but not for her [[FairCop police officer]] role.
* {{Meido}}: Elder Club's 2008 Winter concert.
** Also one of the costumes Ayaka Kimura wore for her surprise English lessons segment on ''Hello Morning''.
* MinorMajorCharacter: Some of the leaders weren't front girls, but they were the ones who held the groups together.
* MsFanservice: Once Aya Matsuura and Miki Fujimoto formed [[MeaningfulName GAM]], every costume they wore was designed to show off their [[ShesGotLegs legs]].
** In one of Ayaka's English lessons, Kaori Iida (jokingly) says she'd like to go to the beach wearing a [[{{Stripperiffic}} see through bikini]]. In another, Mari Yaguchi suggests she [[VaporWear wouldn't bother with a bikini]] at all.
** Sayumi Michishige likes to portray herself as an InnocentFanserviceGirl, but she's not fooling anyone.
* MulticoloredHair: Some of Masae Ohtani's hairstyles. Risako Sugaya also dipped into this trope near the end of Berryz Koubou's run, with hair colors ranging from red to blonde to lavender.
* NeverGotToSayGoodbye: Country Musume member Hiromi Yanagihara died in a car crash. Several members also left unexpectedly.
* NewSoundAlbum: Morning Musume tends to swing back and forth from bubblegum pop to more mature music depending on how old the members of the group are. (Currently their style is more heavily influenced by electronic dance music.)
** Several former members have made albums outside the bubblegum J Pop that Hello! Project is famous for. Ai Kago and Mika Todd both made solo jazz albums, Rika Ishikawa and Hitomi Yoshizawa fronted a DarkerAndEdgier pop punk group called Hangry & Angry, and Maki Goto's solo albums, though still pop, are much HotterAndSexier than her work in HelloProject groups.
* NiceHat: In addition to Kei Yasuda's hat in "Renai Revolution 21", there was some attractive haberdashery on display in the videos for "Koi no Dance Site" and "Kimagure Princess".
* NoSenseOfPersonalSpace: Yuko Nakazawa was well known for embarrassing the other members of Morning Musume by kissing them unexpectedly (especially [[http://www.youtube.com/watch?v=Z0mSocYDUKo Natsumi]] [[http://www.youtube.com/watch?v=qnC62l2H7G8 Abe]]), though it's not so much that she doesn't have a sense of personal space, it's more that she [[{{Jerkass}} doesn't care]]. Sayumi Michishige also had a habit of doing this to Ai Takahashi and Riho Sayashi during concerts.
* OdangoHair: While they were in Mini Moni Mari Yaguchi, Ai Kago and Nozomi Tsuji all wore their hair like this. Tsuji wore hers with twintails, while the others had them without.
** During some of Ayaka's English lesson segments, she had a "Chinese Cafe" where she wore a Chinese style dress and had OdangoHair.
* OlderThanTheyLook: Don't remind [[BerserkButton Yuko Nakazawa that she's getting close to 40]]!
* OneHeadTaller: A few members, notably Hitomi Yoshizawa and Kaori Iida, tend to stand out amongst the short statures of the rest of the group, especially compared to the likes of Mari Yaguchi. Junjun also had more than 16 centimetres (roughly 6 inches) on Reina Tanaka.
** Yurina Kumai of Berryz Koubou towered over the majority of Hello! Project with a height of 176cm. Or is it 178? She's freakishly tall for a teenage Japanese girl, let's just leave it at that.
** Volleyball player and Olympian Motoko Obayashi, who is 182cm, released a single under the name "Deka Moni" (Huge Moni). While not officially under Hello Project, the single was produced by Tsunku and included a cover of Mini Moni's "Jankenpyon".
** Inverted by Mini Moni (Mari Yaguchi, Ai Kago, Nozomi Tsuji and Mika Todd, then Ai Takahashi replaced Yaguchi when she left.) Their gimmick was that they were all no more than 150cm (about 4ft 11 inches) tall when the group first came together.
** Similarly inverted by the 4'11" Ayumi Ishida.
* OneLetterName: W. Also known (fortunately) as Double You.
* {{Otaku}}: Hardcore {{Fanboy}}s, called ''wota'', collect special edition [=CDs=] and merchandising (photobooks, calendars, etc.), and try to go to as many concerts and "handshake events" as possible. At concerts they wave glowsticks or perform elaborate cheering and dancing routines called [[http://en.wikipedia.org/wiki/Wotagei wotagei]].
** Tenshin Mukai is a comedian who sometimes shows up on variety shows that Mari Yaguchi is on, acting as an [[StalkerWithACrush obsessive]] {{otaku}}.
* OverlyLongName: One of the subgroups is ''Morning Musume Tanjou 10nen Kinentai'' (lit. Morning Musume 10 year Celebration Group). There's also ''Athena & Robikerottsu'' and ''Taiyou to Ciscomoon'' (later changed to ''T&C BOMBER''.)
** The first A-side for Ai's last single: "Kono Chikyuu no Heiwa no Honki de Negatterun da yo!" (I'm Really Hoping for Peace on Earth!) Which was then paired with the ''slightly'' shorter, though no less unwieldy, "Kare to Issho ni Omise ga Shitai!" (I Want to Open a Shop With My Boyfriend!)
** S/mileage's "Onaji Jikyuu de Hataraku Tomodachi no Bijin Mama".
* PimpedOutDress: Common in concerts (especially graduation concerts, where the departing girl's dress is more pimped out than any of the others') and music videos.
** PrettyInMink: Kaori Iida plays it very straight in the PV for "I WISH" where she wears a fur coat. Some of the costumes in the [=PV=] for "Renai Revolution 21" are also fur lined -- Kei Yasuda's includes a [[NiceHat furry stetson]].
* PlayboyBunny: ''Viyuden'''s ''Aisucream to My Purin''.
* PreciousPuppies: The video for "Hey Mirai" by Morning Musume.
* PungeonMaster: Iida Kaori, Maeda Yuuka.
** In Kaori's case at least, they're usually [[JustForPun pretty bad]].
* PyrrhicVictory: A personal one for Tsunku. After his laryngeal cancer came back, he had his vocal cords surgically removed. To reiterate, he had to sacrifice his voice in order to fight his cancer. As a result, he can never speak again.
* RagsToRoyalty: Nearly everyone.
* RubberFace: Niigaki Risa.
* TheRunnerUpTakesItAll: In 1997 Tsunku ran a competition to find a new rock vocalist that was won by Heike Michiyo, he later decided to create an all girl group made up of the five runners up and challenged them to sell 50000 copies of their first single with only five promotional events, they managed it in four and Morning Musume went on to be incredibly successful.
* SailorFuku: Matsuura Aya wears one in the video for LOVE Namida Iro.
** Morning Musume '15 wear blazer-style uniforms in the "Seishun Kozou ga Naiteiru (Another Ver.)" PV.
* ScreamsLikeALittleGirl: Granted, half of them ARE little girls, but still...
** Subverted by Takahashi Ai- when surprised, [[http://www.youtube.com/watch?v=Q1fgccqW13s she screams in a low voice]].
* ScrewPolitenessImASenior!: Used comically by Yasuda Kei's Granny character in the "Until the Bus Comes" part of Hello Morning Theatre
* SeasonFinale: Hello! Morning. Also, most members and some units get graduation concerts.
* ShesGotLegs: Matsuura Aya and Fujimoto Miki a.k.a [[MeaningfulName GAM]]. Also Iida Kaori on occasion.
* ShipSinking: Shippers for Matsuura Aya and Fujimoto Miki got sunk when Miki got married.
* ShrinkingViolet: Yasuda Kei used to be a frequent victim of this. After she graduated, Ogawa Makoto took her place.
* SillyLoveSongs: A lot of them.
* SingerNamedrop: Morning Musume do it near the end of "Love Machine".
* SmokingIsCool: Kago thought it was.
* SpellingSong: Mini Moni's Kazoue Uta is about counting in the bath in Japanese and English.
** The same song had a Date version.
*** Mini Moni also had a song that listed all the Japanese Prefectures and their respective Capitals- in fact Mini Moni's songs were aimed at young children, so many had an educational message of some kind. This was more important during their stage shows.
* SpellMyNameWithAnS: Most of the Coconuts Musume members were from Hawaii, therefore they had English names (April, Danielle, Lehua). There's also Viyuden (or Biyuden, Viyuuden, Biyuuden, v-u-den, etc). Junjun and Linlin are nicknamed as such because the management thought it would be too hard for fans to pronounce. Li Chun became Junjun and Qian Lin became Linlin.
* StageNames: Tsunku's real name is Terada Mitsuo. Li Chun and Qian Lin are Junjun and Linlin respectively, Honda Ruru was [=RuRu=], and Miyoshi Chinatsu's real name is Tani Rumiko. Tsuji Nozomi changed her surname to Sugiura upon marriage, but she has stated that she will continue to use Tsuji. Similarly, Iida Kaori has continued to use her maiden name professionally. Ice [=CreaMusume=]'s names are all nicknames.
* StalkerWithACrush: Tenshin Mukai appears as this on variety shows acting like this towards Yaguchi Mari, which in one case culminated in a prank where Mari found herself AloneWithThePsycho while trapped in a StalkerShrine.
* StrictlyFormula: While each group's songs are very diverse in sound and vocals they usually all follow the Verse/Chorus/Verse/Chorus/Interlude Of Music/Repetition Of Last Chorus formula
* {{Talkative Loon}}s: Half of them.
* ThirdPersonPerson and VerbalTic: [[NotAllowedToGrowUp 20-year-old]] Tanaka Reina usually refers to herself in third person (actually a common practice in Japanese culture), and occasionally splices her given name into everyday phrases, with results like "Ganbareina!", "Otsukareina!" and "Shitsureina!".
* TokenMiniMoe: Not so token, most members of the major groups début at around 13 years old, some of the Eggs started at 10.
* TokenMinority: The Chinese (and half-Chinese) members, the Koreans (Jang Dayon and Shimmin) and Coconuts Musume (all American, save for Ayaka).
* {{Tomboy}}: A few. Most notable is Yoshizawa Hitomi, who really played this up- in some Okajo segments she was even referred to as 'top boy' (Rika was top girl, see {{Shipping}}).
** TomboyAndGirlyGirl: Any {{shipping}} with Yossi tends to pair her with a very feminine girl like her best friend Rika.
* TookALevelInBadass: Michishige Sayumi of Morning Musume on an episode of Music Fighter.
* TranslatedCoverVersion: Morning Musume's "Summer Night Town" was covered by Coconuts Musume in English.
** Ice Creamusume redid a few Morning Musume songs in Chinese.
** Kusumi Koharu's Koi Kana was covered in Finnish.
* TrillingRs: Shabondama by Morning Musume.
* UpToEleven: At one time Morning Musume had 15 members, and various Shuffle groups have had 11 or more members.
* VitriolicBestBuds: [[{{Jerkass}} Fujimoto Miki]] towards Matsuura Aya: [[http://www.youtube.com/watch?v=56mAwwryTnA observe.]] However it really went both ways and they are actually best friends. Similarly Yoshizawa Hitomi and Ogawa Makoto and Yaguchi Mari and Ishikawa Rika teased one another quite harshly at times.
** Except for the first version the lyrics of Joshi Kashimashi Monogatari sometimes have an element of this as each verse from version 2 on is sung by the person it's about with other members of the group chiming in at the end.
* VocalTagTeam: "Joshi Kashimashi Monogatari," and many more. Special mention should be made of the track "[[http://projecthello.com/momusu/why.html Why]]" on ''3rd -LOVE Paradise-,'' in which the lead vocal changes ''every syllable.''
* [[WhyDidItHaveToBeSnakes Why Did It Have To Be...]]
** Snakes?: Yoshizawa Hitomi.
** Reptiles?: Yaguchi Mari is not a fan.
** Birds?: Ishikawa Rika is afraid of birds ''and'' feathers.
** Bananas?: Nakazawa Yuko hates them.
** Balloons?: Iida Kaori really doesn't like them, especially [[EarthShatteringKaboom when they pop]].
* [[WidgetSeries Weird Japanese Thing]]: As far as the majority of people outside Japan are concerned.
* WouldHitAGirl: As noted above, Iida Kaori found herself on the receiving end of this trope, especially when Morning Musume appeared on Utaban.
** Okamura Takashi also invoked this against Yaguchi Mari, but unlike Iida she was willing to hit back.
* ZettaiRyouiki: Most grades, particularly C and B, are in evidence in the PV for Kanashimi Twilight.
** Iida Kaori in Mr Moonlight hits A grade with her LittleBlackDress and stockings combo.
** In the Resonant Blue PV from Morning Musume 4 out of the 9 members are showing A grade ZettaiRyouiki, the rest are wearing trousers.
