Udagawa Gosuke is a low-ranking samurai in Japan's Edo period. Upon his marriage to Shino, Gosuke is inspired to create his own dojo that will accept anybody who wants to learn the way of the sword.

In so doing, he gathers disciples but also attracts the attention of the Kobukan Dojo, a dojo that enforces the strict codes of ''bushido'' and punishes those samurai who disobey or break them.

''Samurai Usagi'' by Teppei Fukushima chronicles Gosuke's adventures as he tries to build the Usagi Dojo into a dojo that rivals the Kobukan itself, while also trying to get the hang of married life with Shino.

Among the dojo's disciples are Shino's brother Settsu Masayuki; a peasant priest, Chiyokichi; a strange little man named Maro; hot-blooded Kazama Hanzou; and mysterious Honami Tasuke.

Also, unlike most {{Shonen}} manga, the hero and heroine are actually ''married''.

Not to be confused with ''ComicBook/UsagiYojimbo''.
----
* AnimalThemeNaming: The Ronins:
** [[DarkChick Suzume]]: sparrow
** [[BigBad Mozuku]]: ''mozu''=shrike, ''ku''=nine
** [[{{Bishounen}} Ootori]]: literally "larger bird"/phoenix
** [[FourEyesZeroSoul Tsuruya]]: ''tsuru''=crane, ''ya''=shop
** [[{{Gonk}} Uzura]]: quail
* AwLookTheyReallyDoLoveEachOther: As awkward as Gosuke can be when it comes to his marriage to Shino, there is never any doubt that he adores her.
* {{Bishounen}}: Ootori the ronin's face is so pretty it clashes with his tattoos and coarse way of speaking.
* CompellingVoice: Semi-example: Maro has no magic powers but he is [[spoiler: the eldest son of the local lord]] so everyone "followed whatever he said as if it were an order" to such an extreme that he stopped speaking and ran away from home.
* CryCute: Shino, and later [[spoiler: Suzume.]]
* DefectorFromDecadence: [[spoiler: Honami]] was previously a member of the Kobukan dojo, but left in favor of the Usagi Dojo.
** [[spoiler: All five of the samurai-hating ''ronin'' come from samurai families and were rejected for various reasons]]
* EyesAlwaysShut: Honami Tasuke and his father Hikozaemon.
* TheFightingNarcissist / MoreHeroThanThou / GloryHound: What the ronins believe samurai are like vs. [[RagTagBunchOfMisfits who they're actually fighting]].
* FiveManBand
** FiveBadBand / QuirkyMiniBossSquad: The ronins.
* FullPotentialUpgrade: While the Usagi Dojo's members were already formidable, the katana personally forged for them by Kiyohito, and the training received while waiting for those weapons, make them even more so.
* HardDrinkingPartyGirl: Chiyokichi's sister.
* {{Gonk}}: The Hulk-like ronin Uzura has [[BlackEyesOfEvil jet-black eyes]] and [[TheNoseless apparently no nose]], which is probably why [[spoiler: he was rejected by his samurai family]]. Actually [[spoiler: he's a skinny dude in a fat suit]].
* HighHeelFaceTurn: [[spoiler: Suzume. When ''[[TheVoiceless Maro]]'' says something in your defense you can't help but try to see things differently.]]
* ImprobableWeaponUser: Things used as weapons other than swords: Ootori's umbrella, Chiyokichi's hoe, and Suzume's butcher knife nun-chucks.
* KnightTemplar: The Kobukan Dojo. At least [[PsychoSupporter one member]] is just ''itching'' to administer justice.
** Things that are punishable by death: [[PimpedOutDress dressing too richly]], [[LimitedWardrobe dressing too poorly]], partying too much and neglecting your family; partying too little and being constrained by your family; [[ArsonMurderAndJayWalking improper toothpick presentation.]]
* LittleMissBadAss: Suzume the ronin. Her weapon of choice are a pair of ''butcher knife nun-chucks''.
* MaskPower: Asuka the masked street performer who apparently befriended the ronins, starting with Ootori. [[spoiler: The mask hides the fact that he's blind.]]
* MundaneMadeAwesome: Chiyokichi's "nana herbs". They're not much more than weeds, but Chiyokichi's enthusiasm makes them powerful.
* NoKillLikeOverkill: In order for the ronins to compete against real samurai [[spoiler: they kill ''an entire dojo'' save its leader]].
* PerfectlyArrangedMarriage: Gosuke and Shino, arranged by Settsu.
* TheQuietOne: Maro, as noted in CompellingVoice. The reason he's called Maro at all is because that's all anybody heard of his name when he introduced himself, his full name being Honma Rozan.
* SickeningSweethearts: The leader of the Yamaneko Dojo and his girlfriend.
* TragicKeepsake: Ootori's ''go'' stones. [[spoiler: Asuka would give him candy if he could guess how many stones were white. Ootori took advantage of this after running away from home, only to learn Asuka was blind and "let him win" because he trusted him.]] They're clearly important so Ootori is confused why Settsu doesn't go for them in their match.
* WellDoneSonGuy: Ootori the ronin as a kid. Already on notice for being a less-than-stellar swordsman, [[spoiler: his "friend" switched his sword for an umbrella, forfeiting an important match and humiliating his father. His dad gave him a knife and told him to redeem himself by committing ''seppuku''.]]
* WellIntentionedExtremist: Mozuku wants a world without arrogant samurai, and what better way to do that then to KillEmAll?
