* ActorAllusion: Creator/RumiShishido, who voices Onpu Segawa, was an IdolSinger back in her hey-day.
* AnimeFirst: The manga series that came about only covered a small amount of the anime and changed several things.
* CelebrityVoiceActor: In the Mexican Spanish dub, Doremi is voiced by the Mexican soap opera actress Vanessa Acosta. This was a pretty unusual casting move for a Mexican actor, since Mexican Spanish dubs for anime series' never use famous actors compared with other dubs from other kinds of stuff (like WesternAnimation, Disney movies, etc.)
** Creator/TomoyoHarada voiced Mirai Sakura in episode 40 of ''Dokkan''.
* CrossDressingVoice: Masaru is voiced by NamiMiyahara, who also [[TalkingtoHimself voices Momoko Asuka.]]
** Akatsuki is voiced by Tomo Saeki, Fujio by MamikoNoto, Leon by Creator/MayumiYamaguchi, and Tooru by Kazumi Okazuki, all of whom are female.
* TheDanza: Igarashi has the same surname as the director of the show, Takuya Igarashi, whether or not it was intentional.
* FanNickname: Season one is sometimes called ''Ojamajo Doremi Carnival'' to distinguish it from the rest of the series. This nickname may have been born out of confusion, since the name of the season's opening theme is "Ojamajo Carnival."
** Another fan nickname for the first season is ''Ojamajo Doremi Mujirushi''. The Japanese word ''mujirushi'' literally means ''unlabeled''.
** Amongst the show's fansub community, the first season is usually referred to simply as ''S1'' (short for ''Season 1'' if you couldn't guess.) ''Sharp'' is also frequently referred to as #, since that's how it's spelled in the title. Oddly enough, ''Motto'' and ''Dokkan'' don't get any nicknames (Unless you count ''Motto'' and ''Dokkan'' as being short for ''Mo~tto!'' and ''Dokk~an!'').
*** One of the fansubbers here: M and D make for very poor and vague nicknames. S1 and # are much more obvious and stand out as to what they represent.
* GodCreatedCanonForeigner: Majo Rhythm, who only appears in the [[VisualNovel PC game]] ''Naisho no Mahou''.
* HeAlsoDid: Yoshihiko Umakoshi, the series character designer, also did the character designs for ''CasshernSins'', a show that is largely different in terms of storytelling and genre with ''Ojamajo Doremi''. He would later go on to work on two more Toei Animation shows, ''Anime/HeartcatchPrettyCure'' (which seems to take several cues from ''Doremi'', especially when it comes to stylistic choices and inspirations for certain characters) and ''Anime/SaintSeiyaOmega''.
** Singer/songwriter Music/BreeSharp worked as a writer for the English dub.
* HeyItsThatVoice: ChiemiChiba is Doremi and NamiMiyahara voices Momoko and Masaru... not to mention the hundreds of other guest characters have distinctive voice actors including (but not limited to) Creator/AkiraIshida, Creator/TakahiroSakurai, Creator/KumikoWatanabe, etc. Consider their 15-second appearances as a crowning moment of OvershadowedByAwesome.
** Also expands to the 4Kids dub ([[JustifiedTrope though with the number of actors they have, it's to be expected]]).
** Creator/RumiShishido, who voices Onpu, also voices Princess Pearl from ''Anime/FushigiboshiNoFutagohime''.
** The Italian dub has a lot of voice actors who later voiced characters in ''WesternAnimation/MyLittlePonyFriendshipIsMagic'': Doremi is Sunset Shimmer, Onpu is Twilight Sparkle, Aiko is Twist, Pop is Sweetie Belle, the teachers are Zecora and Apple Bloom, Momoko is Rainbow Dash...
* KeepCirculatingTheTapes: 4Kids has not released anything past the first series. In addition, the majority of the original Japanese DVD sets are out of print, making it hard to access the show.
** There was once a Portuguese dub in Canal Panda. If you didn't see it while it was being shown on TV, you have [[LostForever lost it forever]]. Even finding the show from people who did record it is nigh-impossible on the internet. Only some random episodes can be found from this dub.
* MissingEpisode: Episode 30 ("I Want to See a Ghost!") from the first season was cut in the English dub for unknown reasons.
* NamesTheSame: [[TagalongKid Pop]] shares her name with a fairy from Anime/SmilePrettyCure.
** Akatsuki shares his name with a [[{{Manga/Naruto}} certain criminal organization]].
** Remember Nozomi, the LittlestCancerPatient from ''Na-i-sho''? Well, later on, [[PrettyCure a certain other]] MagicalGirl CashCowFranchise by Toei eventually named [[YesPrettyCure5 one of its leads]] Nozomi. Said lead, to boot, also shares a lot of traits with Doremi (most notably the pink-colored outfits and the [[{{Dojikko}} clumsiness]]).
*** That's a typical {{Magical Girl}} formula, though, and "Nozomi" isn't an unusual name in Japan...
* NoExportForYou: Only the first series made it to the US, and it doesn't seem like the other series, films, and other parts of the franchise will make it (and on the off-chance they do, it's an almost certain fact that 4Kids won't be handling them since Toei cut off all ties with them due to ''Manga/OnePiece'').
* NonSingingVoice: The Italian dub does it in Season 2; [[UncannyValley creepily so]], having four little girls singing with the same, adult voice. Averted in later seasons, and it's better like that since Emanuela Pacotto, Onpu's Italian VA, is an ''amazing'' singer (she also did [[Manga/ShugoChara Utau Hoshina]] and [[WesternAnimation/MyLittlePonyFriendshipIsMagic Twilight Sparkle]], always singing in her voice).
* OneOfUs: Kento Senga and Toshiya Miyata from the JPop BoyBand Kis-My-Ft2 [[http://matanagareruradio.tumblr.com/post/62610542601/kisumai-radio-2013-08-28-senga-comes-out-in-the mentioned on their radio show]] that they've watched this show growing up, and Senga had to keep it a secret from his friends since it wasn't popular among boys. Miyata has even admitted to having "Ojamajo Carnival!!" as his cell phone ringtone in middle school and being a fan of Onpu.
* TheOtherDarrin: Yuka Shino filled in for Creator/SawaIshige in episode 27 of the first series.
** Oyajide was originally voiced by Ginzo Matsuo until [[AuthorExistenceFailure his death]] in the middle of ''Motto'', causing him to be replaced by Nobuaki Kanemitsu.
* PostScriptSeason: Every series after ''S1'' could be considered this. ''Sharp'' especially since it [[RecycledScript reuses a few plot elements and points]].
* RealLifeRelative: In the Mexican Spanish dub, Doremi and her mother Haruka (voiced in Spanish by Vanessa Acosta and Dulce Maria Romay respectively) are daughter and mother in RealLife.
* RecycledScript: The [[PostScriptSeason Post Script Seasons]]. ''Sharp'' especially, but ''Motto'' and ''Dokkan'' have this to a degree.
** To elaborate: In the first episode, Doremi envisioned herself as a Witch Frog; during an early episode of ''Dokkan'', Hana-chan did the same thing. Doremi's actions caused Dodo to fly away in tears during ''S1''; in ''Sharp'', Doremi's actions caused her to leave again, albeit this time in a huff.
* TalkingToHimself: Nami Miyahara voices both Momoko'' and'' Masaru, and there is an episode where they interact.
* WhatCouldHaveBeen: Doremi was originally designed with double ponytails before ending up with her double chignon hairstyle. Hana went through several revisions, including outfits that sported a dress instead of shorts, and different hairstyles.
* TheWikiRule: 5 of them! [[http://doremi.wikia.com/wiki/ Three]] [[http://prettywitch.wikia.com/wiki/ of]] [[http://magicaldoremi.wikia.com/wiki/ them]] are hardly worth the mention due to incompleteness, [[http://ojamajodoremi.wikia.com/wiki/Homepage one has a lot of information with smallish pages]], and [[http://ojamajowitchling.wikia.com/wiki/ the other has a fanon page ''and'' more details per page]].
* ChiemiChiba, Tomoko Akiya, Naomi Nagasawa, and Megumi Takamura originally auditioned for the role of Pop. Along with Creator/SawaIshige, Nagasawa and Takamura also auditioned for Doremi as well.
