1925, Japan. The Taishou era is nearing its end, an era that increased the western influence of the Meiji era. Among other things, the now ever-present "sailor uniform" was introduced in 1920. Another sign of the times was the feminist movement, which began to gain traction. However, Japan is still a very patriarchal society, and even running is seen as a vulgar thing for women to do.

It is to this backdrop that ''Taishou Yakyuu Musume'' is set. A girl in middle school named Akiko Ogasawara is at a party held by her father, wherein the subject of feminism is brought up by one Sousuke Iwasaki. After he voices patriarchal views to Akiko, she becomes angry. She decides to beat Iwasaki at his own game - baseball. Together with her friend Koume Suzukawa, she tries to gather an all-girls baseball team. However, there are many obstacles in the way - finding enough members, learning how to play, continuing in the face of humiliating defeats...

Based on a light novel by Atsushi Kagurasaka. Animated by J.C.Staff. Compare with ''PrincessNine''.
----
!!Tropes in ''Taishou Yakyuu Musume'' include:

* {{Ahoge}}: Kyouko and Kochou.
* ArrangedMarriage:
** Koume is told by her parents to marry Saburou [[PerfectlyArrangedMarriage which seems to suit her just fine]].
** There is also a similar arrangement between Akiko and Iwasaki, the major reason she wants him to recognise her equality.
* BlushSticker: Koume.
* ButchLesbian: Tomoe.
* ButtMonkey: Kyouko. She is [[ThrowTheDogABone thrown a bone]] once in a while, though.
* ChampionsOnTheInside / CrowningMomentOfAwesome: [[spoiler:In the final game,]] although they lost, the score was 9-8. They only lost because Koume's slide was off and she had a few ''millimeters'' left to home base. And they were able to have that score in that match against a middle school men's team that was vying for the nationals.
* [[ClingyJealousGirl Clingy Jealous Sister]]: Shizuka acts like this towards her sister Tomoe. Most probably just being over-protective.
* DaydreamSurprise: The first episode opens on Koume singing a cute rendition of "Tokyo Bushi" (a Japanese song set to the melody of "Marching Through Georgia") in a fashion reminiscent of a musical. It's all in her head.
* DoggedNiceGuy: Takahara.
* DownToTheLastPlay
* EarlyBirdCameo: Kochou appears briefly playing with Kyouko in the first episode.
* HairDecorations: The entire team.
* FlowerInHerHair: Koume
%% * ExactlyWhatItSaysOnTheTin: although the tin is in Japanese.
* ExpressiveHair: Noe
* {{Expy}}: Koume looks and acts a lot like Yurie from ''{{Kamichu}}''. Minus the god-like powers, of course.
* ForeheadOfDoom: Kyouko
* GenkiGirl: Anna-sensei has all the tale-telling signs of having been one. Age has mellowed her out... somewhat.
* HimeCut: A lot.
* HotSpringsEpisode
* IHaveThisFriend: Koume uses this to check her father's opinion on girls playing sports and to get a leatherworker to modify a baseball glove to fit her hand.
* ImTakingHerHomeWithMe: Koume to Tamaki.
* {{Keigo}}: Used by most of the girls and many teachers as is demanded culturally and in their school environment. Special mention goes to Tamaki--although she uses more informal, masculine tenses, she also speaks in a particularly archaic dialect which is a throwback to times when surnames were uncommon and women were referred to by given name with the respectful prefix "o" (eg. Oyuki, Okoume).
* LoverTugOfWar: Tomoe and Akiko, over Koume.
* LuminescentBlush: Often used in combination with Koume's ever present rosy cheeks.
* MartialArtsAndCrafts: Tomoe's kendo skills make her a good batter.
* {{Meganekko}}: Noe
* MiracleRally: Is that Creator/MamikoNoto giving a (gentle, of course) RousingSpeech? Followed by a ThemeMusicPowerUp, even.
* MistakenForCheating: In episode 9, Koume's mom finds a photo of one of Asaka's baseball players that fell out of Koume's drawer. The parents assume that Koume is going out with someone other than her fiancÍ. They approach Koume, who in turn assumes that they're talking about her secret baseball training. HilarityEnsues.
* MundaneMadeAwesome:
** The street batters (and one pitcher) in episode 7. Ninja baseball duels!
** Koume's epic catching in ep 3.
* OneeSama: Tomoe and Shizuka, who have a huge fangirl following amongst the younger students.
* TheOjou: Akiko.
* [[ChickMagnet Person Magnet]]: Koume is popular with boys and girls without even trying.
* PhenotypeStereotype: Anna Curtland, the girls' homeroom teacher and sponsor of the baseball team, complete with the occasional GratuitousEnglish. As far as the {{Eagleland}}er thing goes, she's a lot closer to a Type 1.
* RecordNeedleScratch: All the time.
* RecurringExtra: "Natto, Natto, Natto"
* ReturningTheHandkerchief: Takahara
* TheRoaringTwenties: The Taishou period stretches from 1912 to 1926.
* SailorFuku: Most of the girls except Koume, Shizuka, Tamaki and Noe.
* SchoolgirlLesbians:
** It's lightly implied Tomoe has a thing for Koume. She also has her own passionate fangirl, Kyouko.
** Tomoe blushes while thinking of winning a date with Koume. She spaces out looking at her and gets all worried when Koume shows any interest in other girls (not to mention her reaction to Akiko and Koume "baseball marriage"). RomanticTwoGirlFriendship, at the very least.
** And then her reaction to Koume's fiance.
* SiblingYinYang: Shizuka and Tomoe, the Tsukubae sisters, are characterized in this fashion.
* SpoilerOpening: The team's final composition is shown in the opening.
* StayInTheKitchen:
** That Akiko's fiance thought this was a major factor for her deciding to create a girls' baseball team.
** The principal of his school refused the challenge for this reason.
* TrueCompanions
* {{Tsundere}}: Tamaki Ishigaki. Also Shizuka.
* YouGoGirl: Pretty much the premise of the show.
* YuriFan: Noriko is aware of Tomoe's crush on Koume and tries to convince [[ClingyJealousGirl Shizuka]] to let her be.
-->'''Noriko''': "Oh, I long to shower the [[{{Yuri}} lily's]] calyx with my impassioned feelings..."
