- Belligerent Sexual Tension: With Kyoko.
- Betty and Veronica: The Betty to Mitaka's Veronica.
- Beware the Nice Ones
- Chivalrous Pervert: He may ogle Kyoko all the time but he would never coerce her into doing something she doesn't want to.
- Clueless Chick Magnet: He sometimes doesn't realize just how good-looking he is.
- The Ditherer: To his own detriment, Kyoko's annoyance, and the great comic enjoyment of everyone else. He never grows out of it, but he does learn to take responsibility for the decisions he does finally make.
- Dogged Nice Guy: To Kyoko.
- Drowning My Sorrows: With his best buddy.
- Friend to All Children: He's shown relatively early on to be good with children when Ikuko shows up (though at first he is only nice to her to learn more about Kyoko). The only real exception is Kentaro, which is a more familiar sight in Rumiko Takahashi's works, but Godai occasionally has friendly moments with him too. He goes on to work part-time at a preschool, and eventually becomes a preschool teacher by the end of the series.
- Get a Hold of Yourself, Woman!: He one time slapped Kyoko, because she was just going too far in an argument they were having.
- Happily Married: To Kyoko.
- Innocently Insensitive: He can come off as a jerk, but he doesn't mean it.
- Likes Older Women: Though Kyoko is only about 2 years older than him.

- Babies Ever After: At the end of the series, she and Godai get married and have a daughter.
- Belligerent Sexual Tension: With Godai.
- Betty and Veronica: In a way she has been both; while she is the Betty to Ibuki's Veronica, she is the Veronica to Kozue's Betty.
- Cannot Spit It Out: For all the grief she gives Godai over his reluctance to break up with Kozue, Kyoko is equally guilty in terms of her relationship with Shun Mitaka. Though it's clear that she cares for him, it's also blatantly obvious that she doesn't see Mitaka as somebody she wants to marry. However, she doesn't say anything when Mitaka breaks off his engagement to Asuna to be with her, nor does she deny a relationship when Asuna politely confronts her about it. Even after meeting his parents, and being whisked away by Shun while Godai is screaming after them, she doesn't spit it out that she doesn't feel that way for him until the very last minute.
- Can't Hold Her Liquor: Usually avoids drinking too much as a result.
- Clingy Jealous Girl: Has shades of this. She doesn't like Godai seeing other girls but still bravely resists Ibuki's provocations.

- Stepford Smiler: Despite her sunny disposition, she's still mourning her late husband.
- Teacher/Student Romance: She met her late husband while he was working as a temporary teacher at her high school.

- Widow Woman
- Will They or Won't They?: With Godai. They Do.
- Yamato Nadeshiko: Subverted. Her perfect Japanese housewife persona hides her repressed Tsundere nature and it's a way to cope with the loss of her husband.

- The Casanova: Known for his romantic conquests, he actually has to convince Kyoko that he isn't all about sex.

- He actually thought he could really like Asuna if he hasn't already set his sights on Kyoko.
- Rich Idiot with No Day Job: Although not an idiot, it is clearly implied that he's so freaking loaded that he doesn't need to work.
- The Rival: To Godai.
- Sensitive Guy and Manly Man: Manly Man to Godai's Sensitive Guy.
- Shotgun Wedding: After a previous drunken night with Asuna, Mitaka hears that "she" is pregnant. He assumes that he got Asuna pregnant, and vows to marry her to set things right. After he proposes and everything is set in stone, he discovers that her dog is the one who had actually been knocked up by his dog.
- Tall, Dark, and Handsome: The best-looking male character of the series.
- Thanks for the Mammary: Happened one time when he tried to prevent Kyoko from falling.
- Twinkle Smile: Iconic of his character.

- The Matchmaker
- Team Mom
- Accent Adaptation: Yotsuya's formal way of speaking is adapted into English as a quasi-British accent.
- Age Lift: While he was of a Vague Age in the manga/anime, in live action adaptations, he tends to get played by clearly middle aged actors.
- Bunny-Ears Lawyer
- Cloud Cuckoo Lander
- Covert Pervert: Has a voyeuristic streak a mile wide.
- Expy: Rumiko Takahashi's Rumic World manga "Dust Spurt" has a secret agent character named Mr. Sekhoi who looks exactly like Yotsuya. This is the source of some fan speculation that they are the same person.
- Four Is Death: Stays in room 4, his name has a four in it, and he's easily Godai's most disruptive neighbor.

- Deadpan Snarker: Likes to snipe at Godai and Kyoko for her own amusement.
- Fiery Redhead
- Hooker with a Heart of Gold: A variation. She isn't a hooker but a late-night barmaid which is regarded as somewhat similar in Japan (even though sex isn't necessarily involved). As for the heart of gold, it shows up later in the series when she decides to step in and trigger Kyoko's jealousy and force her to be more honest with herself with regards to Godai.
- Lady Drunk
- Last Minute Hookup: With Master.
- Ms. Fanservice
- "The Reason You Suck" Speech: Akemi lays a brief but huge one on Kyoko after Kyoko's ultimate hissy-fit towards Godai.Akemi: I can't believe you.

- She's Got Legs
- The Tease: More than being actually promiscuous, she is more about teasing than actually doing it.
- Urban Legend Love Life: Despite her sultry demeanour and her job, she hasn't been with as many men as people think.
Voiced by: Ryo Horikawa (JP)Originally intending to move into an upscale establishment called "Rikkoku-kan", a typographical error on the lease papers brings him to Maison Ikkoku relatively late into the story as an accidental tenant. He led a relatively sheltered life before entering the story, and he moved into Maison Ikkoku as he started college against the wishes of his protective mother.

- The Unseen: A manga-only character.

- Na´ve Everygirl: The most normal person Godai knows.
- Nice Girl: Linked to the trope above, she's also one of the nicest. Her only real flaw is how oblivious she can be regarding Godai's true romantic feelings.
- Power Hair: Subverted. She does have the hairstyle but she is no leader.
- Put on a Bus: Literally put on a train when she figures Godai is in love with someone else than her.
- The Bus Came Back: For the epilogue where we see that she has moved on to a whole new life.

- Betty and Veronica: The Veronica to Kyoko's Betty.
- Bitch in Sheep's Clothing: Acts nice and all, but it's only a veneer that hides a much less appealing personality.

- Daddy's Girl
- Expository Hairstyle Change
- Fille Fatale
- Girlish Pigtails
- Hot for Teacher: She gets a crush on Godai while he works as a student-teacher at her class. It's entirely one sided on Ibuki's part, but it still heavily bothers Kyoko, even if Godai doesn't reciprocate Ibuki's feelings. Probably because it reminds her of something.
- In Love with Love: She appears to be more interested in being in a tragic romance than in Godai himself.
- Jerk with a Heart of Gold: While she is a lot less sympathetic than the likes of Kozue and is often seen as a temperamental brat who needs to learn that she can't always get what she wants, Ibuki does occasionally get some sympathetic moments and even occasionally does try to help Godai out.

- Babies Ever After: With Mitaka.
- Fragile Flower: She looks so pure and fragile that even Godai and Kyoko where shocked when they see her pregnant with Mitaka's children.
- Shown in a huge way when Shun tries to break off their engagement initially. She faints on the spot and when she wakes up she immediately cries, much to Mitaka's discomfort.

Even though she feels anguished inside she can't bring herself to be mean to Kyoko and is instead very awkwardly pleasant to her.
- Happily Married: To Mitaka.
- I Feel Angry: Never visibly angry. When she learns about the existence of Kyoko, she just kindly tells her that she doesn't approve of Kyoko courting her fiancé.
- Mistaken for Pregnant: After a previous drunken night with Asuna and hearing "she" is pregnant, Mitaka assumes that he got Asuna pregnant, and vows to marry her to set things right. After he proposes and everything is set in stone, she reveals it's her dog who's pregnant.
- Na´ve Everygirl: Not as Everygirl as Kozue, given her family's just as rich as the Mitakas.
- Perfectly Arranged Marriage: She is head over heels in love with her arranged fiance Mitaka and after proposing to her due to a misunderstanding he eventually falls in love with her and they get married.

And since most of these happenings get more misconstrued by the drunken antics of the characters, he's often the one stepping in to clarify what everything was really about.
