This is a list of characters who appear in Midnight Diner.

    open/close all folders 

The proprietor of Meshi-ya, the Master serves as the protagonist of the series, appearing in all episodes and the movies.

  • Everybody Has Standards: Male patrons physically duking it out in his restaurant? Poor their cold drinks over their heads to cool them down; a male patron abusing his girlfriend? The Master will crack a bottle of beer over the man's head.
  • Good Smoking, Evil Smoking: Most of the time when the Master smokes is during either an insightful conversation or a poignant scene.
  • Good Scars, Evil Scars: One across his left eye
  • Mysterious Past: The Master's origins are never discussed nor shown.
  • Supreme Chef: Played with; though it might seem like the Master can cook anything his customers want, he states there are some dishes that even he can't do like sushi. Exaggerated when he orders gyoza (dumplings) from a nearby take-out restaurant as an order from a customer because the Master claims he can't make gyoza as good as the owner's; it leads to that owner teaching the Master his gyoza recipe.

Regular Customers of Meshi-ya

Characters listed here at those who have appeared in at least one episode of every "season" and the movies.
    Ryu Kenzaki 

A local Yakuza boss who runs an illegal gambling ring, Ryu's Trademark Favorite Food are cooked red weiners cut into the shape of an octopus.

  • Even Evil Has Standards: Played with as Ryu is hardly "evil".
    • Despite his gambling operations being illegal, he scolds his underling Gen for taking gambling bets on professional baseball games from high school students. Turns out there's a good reason for that.
    • Although he doesn't share the same feelings that Kosuzu has for him, Ryu nevertheless helps him get rid of a few disturbing patrons at his bar off-screen.
  • Tall, Dark, and Handsome: A tall, imposing man who wears a black suit and always dons a pair of sunglasses, his physical attributes serve as an attraction to Kosuzu and his eccentric friends. Visually exemplified in a black-and-white photograph taken by Komichi when he opens his gala, mesmerizing Kosuzu enough to call Ryu "beautiful".
  • Why Did It Have to Be Snakes?: After Kanemoto's tells a ghost story in the last episode of Tokyo Stories, Ryu flies into hysterics when he hallucinates aliens and ghosts, unable to ever eat watermelon ever again.


Owner of a gay bar in the same neighborhood as Meshi-ya, Kosuzu's Trademark Favorite Food is tamagoyaki (grilled egg rolls).

  • Camp Gay: Though compared to his friends, Kosuzu appears the least camp of the bunch, particularly when Ko has a far more flamboyent appearance.

    Mariko "Marilyn" Matsushima 

An old-school stripper, Marilyn has trouble establishing firm relationships with men, so much that after many failed tries, she settles on Kimitoshi, a chiropractor. Her Trademark Favorite Food are cabbage rolls.

  • Does This Remind You of Anything?: Invoked; after she starts dating Kimitoshi, she replies to Chu and Komichi that what attracted her to him the most is not just "his heart", but also "his hands".

    Gen Hayashi 

Part of Ryu's Yakuza group, Gen's Trademark Favorite Food is kinpira gobo (braised burdock root). He also hates dishes that are too hot to eat (rather than spicy) because it burns the roof of his mouth.

  • Can't Hold His Liquor: Gin can't handle a lot of alcohol; in fact, he occassionally orders a beer to go with his food, but won't drink it.
  • Heroic BSoD: Upon finding out his old high school teacher, whom he loved, has died, Gen goes into a fit of rage and breaks down crying.
  • Jerk with a Heart of Gold: Given he's a gangster, Gen has attitude problems and is easily triggered to anger, but upon hearing of how hard Saya is working late-night shifts at pachinko parlors, he pays for her meal. Additionally, he confronts and intimidates Saya's abusive boyfriend for taking their relationship for granted.


  • The Straight Man: The most logical and reasonable patron of the regulars; Chu also has the least amount of "wackiness" compared to the rest of the cast.


An amateur photographer

  • All Love Is Unrequited: Has been trying to gain Kasumi's affections since her appearance, but to no avail, as she has zero interest in him.
  • Book Dumb: More often than not, Komichi fails to state even the most basic explanations.

    Kana, Miki and Rumi 

A trio of 30-year old office workers, they are the most attuned to gossip of the Meshi-ya customers. Collectively, ochazuke (tea poured over cooked rice) is their Trademark Favorite Food.


A middle-aged Salaryman

  • The Smart Guy: Of the regular patrons, Kanemoto is the most knowledgeable of random facts, such as the origins of the "highball" drink.


  • Flat Character: Whereas most of the regular and recurring patrons have a particular quirk or trait, Hachiro has nothing significant or unusual about him that stands out.

  • Heroic BSoD: When his mother contracts Alzhemier's Disease, Oki returns home to visit her, except she doesn't recognize him. He tearfully apologizes, lamenting his ill-strickened mother only remembers the days when he was a boy who loved to eat potato salad. Oki urges his porn trainee Tanaka to not neglect his own injured mother in the hospital as Oki did with his.
  • Meaningful Name: "Oki" literally means "big wood".

A renowned police detective, who happens to be Ryu's high school classmate, his Trademark Favorite Food are Chinese chives with liver.

  • Consummate Professional: Noguchi lambasts his partner Natsuki for her unorthodox detective work and her empathizing with crime victims when it's not a detective's job to do the latter. Subverted when she discovers he's been doing that himself by attempting to court a single mother.

    Saya Adachi 

A clerk working for a pachinko parlor during late-nights, Saya was in a relationship with a failing comedian after graduating from high school, but broke it off after her boyfriend was goaded by Gen.
