Japanese Sex-Related Terms

NSFW: this article may contain words or images you'd rather not have your boss see.

A lot of manga and anime feature sex-related jokes, or dirty jokes, "low jokes," shimoneta 下ネタ, besides those that are simply sexual in nature, like of the ecchi and hentai genres. So, for reference, a list of sex-related Japanese vocabulary.

Anatomy

Let's start with the technical terms for sex-related anatomy. This is mostly the NSFW continuation of the full article about Body Parts.

The words for the genitalia in Japanese:

  • seiki
    性器
    Sex organ.
    • sei~ - "sexual."
    • ~ki - "organ," "device, "instrument."
  • danseiki
    男性器
    Male sex organ.
    • dansei - "male," "men."
  • joseiki
    女性器
    Female sex organ.
    • josei - "female," "women."
  • naiseiki
    内性器
    Internal sex organ.
  • gaiseiki
    外性器
    External sex organ.
  • seishoku
    生殖
    Reproduction.
  • seishokuki
    生殖器
    Reproductive organ. Genital.
  • inbu
    陰部
    Genital area.
    • in 陰 means "unseen" and bu 部 means "part." So the term is literally "private parts."

Parts of the male sexual organ:

  • inkei
    陰茎
    Penis.
  • kitou 亀頭
    inkei kitou 陰茎亀頭
    Glans. Glans penis.
  • kari-kubi カリ首
    kari カリ
    inkei kitoukan 陰茎亀頭冠
    inkei kitoukou 陰茎亀頭溝
    Penis crown. Corona of glans penis.

  • inkei shoutai
    陰茎小帯
    Penile frenulum.
  • inkei kyaku
    陰茎脚
    Crus of penis.
    • Since ashi 脚 means "legs," this is literally the "penis' legs."
  • inkei wana jintai
    陰茎ワナ靭帯
    Fundiform ligament of the penis.
  • seinou
    精嚢
    Seminal vesicle. Seminal glands.
  • shaseikan

  • seisou

    Testicle.
    • Contrary to popular belief, semen isn't stored in the testicles.
    • Sperm is stored in the testicles.
    • Semen is 5% sperm, 95% other stuff.
    • Pee isn't stored in the testicles either.
  • kougan
    睾丸
    Testicle.
    • Another term for testicle.
    • Note that maru 丸 means "round," while su 巣 means "nest," so you could say one comes from its form and the other from its function. So, for example, toward animals whose testicles don't resemble balls, kougan wouldn't be used.
  • in'nou
    陰嚢
    Scrotum.
  • seisou shouyou
    精巣小葉

  • chitsu
    shitsu
    Vagina.
    • The "vagina" is an internal tube connecting the uterus to the outside of the body.
    • In English, a lot of people use the term "vagina" to refer to the vulva, which is technically not the same thing as the vagina.
    • vagina ヴァギナ
      wagina ワギナ
      "Vagina."
  • chitsukou
    膣口
    Ostium of the vagina. "Vaginal opening."
  • shojomaku
    処女膜
    Hymen.
    • The word shojo 処女 means a female "virgin," and maku 膜 means a "membrane." So this term means literally "virgin membrane."
    • Despite popular belief held in dozens of countries worldwide and through history, a virgin doesn't necessarily have an intact hymen: it can tear and rip apart for countless reasons.
    • Of course 21st century Japanese doctors know this.
    • Even so, shojomaku is still the formal term for "hymen" in Japanese. It's not a slang.
    • By the way, "hymen" comes from the Greek humēn, which means "membrane," and has nothing to do with virgins.
  • chitsuengai
    膣円蓋
    Vaginal fornix.
  • shikyuu
    子宮
    Uterus. Womb.
    • For the "womb tattoo" trope, see inmon 淫紋, "lewd crest."

      Vaginal portion of the cervix. Ectocervix.
  • shikyuutai
    子宮体
    Corpus. "Body of the uterus."
    • shikyuukuu
      子宮腔
      Uterine cavity.
    • shikyuutei
      子宮底
      Fundus. "Bottom of the uterus." (this is actually at the top of the uterus, in the same sense the "bottom" of the barrel is actually at the top of the barrel if it's upside-down.)
  • shikyuuheki 子宮壁
    shikyuu no kabe 子宮の壁
    Uterine wall.
    • shikyuu naimaku 子宮内膜
      Endometrium. "Uterus internal membrane."

Censoring

Sometimes, manko, chinko and chinpo can get censored in manga by replacing a kana with a circle ◯. In anime, it gets bleeped instead.

Generally speaking, manko is more likely to be censored because it can also mean "to have sex," manko suru, so it ends up being sexual, while chinko is only genital.

For reference:

  • マ◯コ, マン◯, おマ◯コ, おマン◯
    ま◯こ, まん◯, おま◯こ, おまん◯
    manko, manko, omanko, omanko.
  • チ◯コ, おチ◯コ
    ち◯こ, おち◯こ
    chinko, ochinko.
  • ◯ンポ, チ◯ポ, お◯ンポ, おチ◯ポ
    ◯んぽ, ち◯ぽ, お◯んぽ, おち◯ぽ
    chinpo, chinpo, ochinpo, ochinpo.
  • チン◯, おチン◯
    ちん◯, おちん◯
    chinko, ochinko, or chinpo, ochinpo.
  • ◯んこ, お◯んこ
    ◯ンコ, お◯ンコ
    chinko, ochinko or manko, omanko.

Since chinchin, ochinchin is not considered vulgar—it's children's language—it's normally not censored, but for the sake of completeness:

  • ◯んちん, ち◯ちん, ちん◯ん, ちんち◯
    ◯ンチン, チ◯チン, チン◯ン, チンチ◯
    chinchin, chinchin, chinchin, chinchin
  • お◯んちん, おち◯ちん, おちん◯ん, おちんち◯
    お◯ンチン, おチ◯チン, おチン◯ン, おチンチ◯
    ochinchin, ochinchin, ochinchin, ochinchin

Other Terms

There are dozens of other colloquialisms, analogies and slangs for sexual body parts.

Let's start with the obvious ones for the testicles:

  • tama

    Balls. Ball. (literally.)
    • Also a common name for a pet cat: tama タマ, for dog it's pochi ポチ, "spot."
  • kintama
    金玉
    Golden balls.
    • In English, "jewels" are used similarly.
  • tamatama
    タマタマ
    Balls. (reduplicated plural.)
    • Body terms featuring plurality by reduplication, otete お手手, omeme お目目, are normally used when talking to little children, babies, or in rare cases when someone is being condescending, treating someone else like a baby. In this case, it's because some adult women think tamatama is a cute-ish way of referring to the "balls" of an adult man.

For penis:

  • sao
    竿
    Stick. Pole.
  • nikusao
    肉竿
    Meat stick.
  • bou

    Stick. Pole.
  • nikubou
    肉棒
    Meat stick.

Some words that somehow also mean penis:

  • musuko 息子
    gusoku 愚息
    segare
    Son.
    • Yes, "son," as in, not a daughter. Like "my son" is an innuendo for "my penis."
    • itsumo musuko ga osewa ni natte-orimasu
      いつも息子がお世話になっております
      [My] son has been often in [your] care. (literally, a phrase you could use toward a teacher or babysitter who has taken care of your son.)

  • ichimotsu
    一物
    "One thing."
    • That's what it means. "One thing."
    • Okay, it can also mean something you have "hidden," like in your chest, a secret, so maybe it comes from that meaning instead.
  • mono
    モノ (or 物)
    "Thing." (just "thing," like, "his thing," etc.)

  • meimei chinko
    命名 ちん子
    Name: Chinko.
    • ko
      A common suffix in names of girls. Yuuko 優子, Hanako 花子, etc.

There are even pairings like this mountainous one:

Or this religious one:

  • mara
    魔羅
    In Buddhism, mara is a demon that tempted the Buddha with visions of seducing women.
    (male genital.)
  • kan'non-sama
    観音様
    Avalokiteśvara, the bodhisattva. Guanyin.
    (female genital.)

And of course, this militaristic one:

  • katana

    Sword. (penis)
  • saya

    Scabbard. (vagina)
  • The term "vagina" comes from Latin, in which it means "sheath" or the "scabbard" of a sword. Similarly, "gladius," which means "sword," was a term for penis.(dartmouth.edu:Etymology of Abdominal Visceral Terms)

Terms for the female genitalia:

  • awabi

    Abalone. Ear shell. (from the shape of the vulva.)
  • mitsutsubo
    蜜壷
    "Honeypot." (vagina.)

Notably, specifically in regards to sex:

  • meiki
    名器
    Famed instrument/utensil. (an excellent vagina.)
    • Often in the sense of:
    • shimari ga ii
      締まりがいい
      "The contraction is good."
      Good at contracting.
    • It can also mean "an excellent penis," apparently.

Specially because Japan has different weird terms for different types of "excellent vaginas," like:

  • mimizu senbiki
    ミミズ千匹
    One thousand worms. (from the texture of the vaginal walls.)
  • kazu-no-ko tenjou
    数の子天井
    Ceiling of herring roe. (from the texture of the superior vaginal wall in missionary position.)
    • zarame

      (synonym.)

      数の子
      Herring roe.
  • takotsubo
    タコツボ (or 蛸壺)
    Octopus pot. (a vagina which tightens on penetration.)
    • Octopus pots are pots used to capture octopuses, by the way. They're placed horizontally on the sea floor, and octopuses get into them because they like to hide and there aren't many places to hide into on the sea floor.
  • kinchaku
    巾着
    Drawstring pouch. (a vagina that tightens entirely.)

Colloquialisms for the "clitoris," kuritorisu クリトリス, include:

Vaginal Discharge

Vaginal discharge is also composed by a bunch of things.

  • chitsu bunpitsueki
    膣分泌液

      Vaginal fluid.

    濡れる
    To get wet. (intransitive.)
    • nurasu
      濡らす
      To wet. (transitive.)
    • In anime, there are some series with female characters whose archetypal personality is basically "horny," who will cling to their romantic interest or with everyone basically, who will exclaim nureru to say "you'll make me wet" as a joke (in the sense it's part of the humor of the series, the character, however, is totally serious about it). Even trap characters may say this as a joke.
    • If I remember correctly, Cthuko, クー子, from Haiyore! Nyaruko-san 這いよれ!ニャル子さん may have done this, for example.
    • This is worth of note because I don't think there's a male equivalent. Male characters don't say something like "you'll make me hard" in the same horny joke sense as this. In particular, Nyaruko-san isn't really about shimoneta or even overly erotic, it's mostly comedy, so you can have a series that looks mostly innocent, but will have a sentence such as this, because it's actually a moe series targeted at otaku, so it assumes its audience won't be fazed by this sort of horny.

There's a term specifically for vaginal discharge while not aroused:

  • orimono
    オリモノ (or 下り物)
    "Falling thing." (normal vaginal discharge.)

セックス

The most common colloquialism for sex would be:

    セックス
    "Sex."
  • sekkusu suru
    セックスする
    "To sex." To have sex.

Some related terms:

  • sekuhara

      (same meaning.)

      To finish well something.
    • kimaru
      キマる
      To get high. (intransitive.)

Some people avoid saying the word sekkusu because it sounds vulgar, preferring something like:

  • ecchi
    エッチ
    Sex.
    Sexy.
    Perverted.
    • Also spelled as an "H."
    • In fact it comes from the letter H, because it comes from the romaji of hentai 変態, which means "pervert."
  • ecchi suru
    エッチする
    To have sex.
    • hitori-ecchi
      一人エッチ
      Sex alone. Masturbation.
  • neru
    寝る
    To sleep.
    To sleep [with someone].
    • Also where comes the infamous terms:
    • netoru
      寝取る
      To take "sleeping."
      To sleep [with someone else's partner].
    • netorareru
      寝取られる
      (passive form.)
      To be netoru'd
      For someone who's not your partner to sleep with you.
    • netorare
      寝取られ
      (the act of the above.)
      Cheating. Cuckolding. (genre.)
    • netorase
      寝取らせ
      Letting netoru. To let someone else sleep with your partner.
      • Generally speaking, netorare as a genre is common in fan art because it uses a character from a series with already-established relationships. If any heroine has sex with anyone but the main character whom they canonically like, that can be netorare, and since they like that character, they wouldn't cheat on him willingly, which results in the netorare genre being infamously associated with non-consensual scenarios. By contrast, netorase means there's consent of the party being cheated on, so it's closer to fetishistic cuckolding in real life.
  • suru
    する
    To do.
    • Just... "to do," e.g. in the volitional form shiyou しよう, "let's do [it]," meaning sekkusu shiyou, "let's have sex." This isn't a separate meaning of the verb suru, this is the suru-verb sekkusu suru or something alike with the verbal noun sekkusu omitted as it's inferred pragmatically.

Or something so far-fetched nobody will actually understand it:

  • nakayoshi
    仲良し
    To make peace. "To get on good terms."

Or something that people don't really say but you may see in anime:

  • gattai
    合体
    To combine.
    • Like giant robots!
合体
Anime: Seitokai Yakuindomo 生徒会役員共 (Episode 8)
  • Context: gattai!

Then we have this extremely confusing word:

  • yaru
    やる
    • To do something.
    • Synonymous with ageru:
      • To give something to someone.
      • To do something for someone.
    • To kill someone.
    • To have sex with someone

And yes, it actually means all that stuff:

  • yaritai koto
    やりたいこと
    Something [you] want to do.
  • banana wo yaru
    バナナをやる
    [I'll] give [you] a banana.

It's seen in the words:

    • tokoroten-shiki

      Tokoroten ceremony.
      When someone is naturally pushed out, usually in a bad sense. For example, in Sumo wrestling there was a rule that there could only be five oozeki 大関. But then a sixth one showed up. So the oldest one of the five was "pushed out" to the next rank, yokodzuna 横綱, in order to maintain five oozeki.
    • And finally, what's relevant to this article:
    • tokoroten
      ところてん
      For a man to have an orgasm from anal alone. (in the sense of "pushing out" the semen from behind.)

In English, the verb "to cum" is a slang for "to orgasm." It's sometimes spelled "to come." Such that "I'm coming" becomes a double entendre. In Japanese, the word for "to come" is kuru 来る, but it doesn't carry this orgasm meaning.

On the other hand, the word iku 行く, "to go," does mean "to orgasm" in Japanese. So "to come" is English and "to go" is Japanese. Why, though? Is this some sort of coincidence or something? Was this on purpose? Anyway, it's normally spelled with katakana, not with kanji:

  • iku
    イく (or イク)
    To cum. To orgasm.
    • When conjugated, it's homonymous with other words, like:
    • iu
      言う
      To say.
    • itta
      言った
      [I] said.
    • itta
      イった
      [I] came.

Terms for orgasm expressions:

  • ikigao
    イキ顔
    "Cumming face." (from iku.)

しゃぶれ・・・・・・
Manga: Inuyashiki いぬやしき (Chapter 18)
Millaarc ミラアルク doing a "chin peace" sign, ago piisu 顎ピース.
Character: Millaarc ミラアルク
Manga: Senki Zesshou Symphogear XV, 戦姫絶唱シンフォギアXV (Episode 3)
  • Context: in some cultures, making a V sign on your mouth like you're spreading is associated with cunnilingus as it evokes such image.(vice.com) In Japan, this is often not the case. A girl doing this is typically just striking a pose called an ago-piisu 顎ピース, "chin peace [sign]."(whynotjapan.com)

A lot of Japanese words for sex have kan 姦 in it, including some made-up slangs about some really weird stuff.

  • wakan
    和姦
    Consensual sex. "Harmonious sex."
  • goukan
    強姦
    Forced sex. "Strength sex." (strength = force.)
  • rinkan
    輪姦
    Gang rape. "Wheel sex." (in the sense of a group surrounding someone.)
  • soukan
    相姦
    Adultery.
  • kinshin soukan
    近親相姦
    Incest.
  • aokan
    青姦
    Sex outdoors. "Blue sex."
  • juukan

    "Machine sex."
  • shikan
    視姦
    Ogling. Leering. "Sight sex."
    • Wait a minute, this isn't actually sex!

Some "grotesque," guro グロ, terms that include kan 姦. Obviously these only refer to illustrations, not real people:

  • noukan
    脳姦
    "Brain sex." Brain-fucking.
  • gankoukan
    眼孔姦
    "Eye socket sex."

レイプ

The word goukan 強姦 is the formal term for "rape" in Japanese. In the general sense, there's also:

  • okasu
    犯す
    To do something you shouldn't do.
    To violate [a law]. To break [a rule].
    To commit [a crime].
    To rape [a person].
  • yaru
    犯る
    To do [a crime].
    To rape [a person.
    • A gikun for yaru やる.

And this word that won't air on TV:

  • reipu
    レイプ
    "Rape."

It has derived terms like:

  • reipu-me
    レイプ目
    "Rape eyes." (as in the victim's.)
    • An anime term referring to the "vacant eyes" drawn in hopeless characters.
  • gyaku-reipu
    逆レイプ
    "Reverse rape."
    • Same logic as nanpa ナンパ, "to hit on," in which you assume it's about men hitting on women, so gyaku-nanpa 逆ナンパ is "women hitting on men."
    • Abbreviated gyaku-re 逆レ and gyaku-nan 逆ナン respectively.
Takakamo Shizuno 高鴨穏乃, example of vacant eyes.
Anime: Saki Achiga-hen 咲-Saki-阿知賀編 Episode of Side-A (Episode 3)
  • Context: "rape" eyes.
ピョン おおっ うおーー父親を犯ろうとしてるー 逆レイプだぁ
Manga: Detroit Metal City, デトロイト・メタル・シティ (Volume 2, Omake, DETROIT・MOE・CITY)
  • Context: death metal fans grotesquely misinterpret an innocent scene.

    おおっ
    Ooh.
  • uo~~ chichioya wo yarou to shiteru~

  • chijo
    痴女
    (female) molester.

Counting

In Japanese, counting is done with rather specific, but also confusingly ambiguous counters. For reference, some words that can end up being taken suggestively:

The counter for penises, phallic objects, dildos, pencils, bananas, swords, strands of hair, arms, legs, and other long, cylindrical objects in general is hon 本.

  • ippon
    一本
    One [banana].
    • banana ippon
      バナナ一本
      "One banana."
  • nihon
    二本
    Two [bananas].
  • sanbon
    三本
    Three [bananas].
  • nanbon
    何本
    An unknown number of [bananas].
    How many [bananas]?

But wait, are testicles part of the penis? Because then it's not cylindrical anymore. Well, let's not think deeply about this.

The counter for vaginas, if we're talking about the vagina as an orifices, would be ana 穴, "hole." Just like the mouth, and the anus, are also holes, except when counting it's normally read with its on'yomi, ketsu 穴, because ichi, ni, san are on'yomi while hito-, futa-, mi- are kun'yomi.

  • ikketsu 1穴
    hito-ana 一穴
  • One hole.
  • niketsu 2欠
    futa-ana ニ穴
    Two holes.
  • sanketsu 3穴
    mi-ana 三穴
    Three holes.
  • nanketsu 何穴
    nan'ana 何穴
    An unknown number of holes.
    How many holes?

The counter for ejaculations, shots, gun shots, hits, strikes, punches, etc. is hatsu 発.

  • ippatsu
    一発
    One shot. One hit.
  • nihatsu
    二発
    Two shots. Two hits.
  • sanpatsu
    三発
    Three shots. Three hits.
  • nanpatsu
    何発
    An unknown number of shots.
    How many shots?

The counter for sexual intercourse, or the number of times anything at all is done repeatedly, is kai 回.

  • ikkai
    一回
    One time. Once.
  • nikai
    二回
    Two times. Twice.
  • sankai
    三回
    Three times. Thrice.
  • nankai
    何回
    An unknown number of times.
    How many times?

The counter for sexual partners, or people in general, is -ri ~人 or nin 人.

  • hitori
    一人
    One person.
  • futari
    二人
    Two people.
  • san'nin
    三人
    Three people.
  • nan'nin
    何人
    An unknown number of people.
    How many people.
    • nan'nin mo
      何人も
      A lot of people. (more people than you can know.)
    • If this is combined with yaru, you get this ambiguity:
    • nan'nin mo yatta
      何人もやった
      [Someone] killed a lot of people.
      [Someone] fucked a lot of people.

In the case of orgies, there's a slang to count the number of people in it: pii ピー, which comes from the katakanization of the English letter P. This P can refer to the "page number" of a book, manga, etc. It can also refer to the number of "players" in a video-game. Which is where the orgy slang probably came from.

  • ichi-pii
    1P
    One player. One page.
  • ni-pii
    2P
    Two players. Page two.
    • ni-pii karaa
      2Pカラー
      Player 2 color. (a different color scheme for a same character, from fighting games where two players can select the same character. E.g. Bowsette blonde and red-hair versions.)
  • san-pii
    3P
    Three players. Page three.
    An orgy of 3 people. Threesome.
  • yon-pii
    4P
    Four players. Page four.
    An orgy of 4 people. Foursome.
  • go-pii
    5P
    Five players. Page five.
    An orgy of 5 people. Fivesome.

Graffiti

Regarding body writing:

  • rakugaki
    落書き
    Scribble. Sketch.
  • karada ni rakugaki
    体に落書き
    Scribble on body. Body graffiti.

Since you could write virtually anything on someone's body, I'm not going to list everything you could write. Instead, let's focus on the noteworthy things:

目暗箱 by 生徒会
Manga: Seitokai Yakuindomo 生徒会役員共 (Volume 1, Chapter 2, Page 16, 魅惑の入り口)
  • Context: the student council president comes up with an idea to make people want to put in suggestion into their suggestion box.
    • meyasubako, by seitokai
      目安箱 by生徒会
      Suggestion box, by student council.
  • omankomaaku おマンコマーク
    mankomaaku マンコマーク
    omekomaaku オメコマーク
    The "pussy mark" refers to a symbol featuring two concentric circles ◎, one vertical line |, and ticks around the outer circle representing pubes.

Note to be confused with:

A "power plant mark," hatsudensho no maaku 発電所のマーク.
Anime: Shimoneta to Iu Gainen ga Sonzai Shinai Taikutsu na Sekai 下ネタという概念が存在しない退屈な世界 (Episode 2)
  • hatsudensho no maaku
    発電所のマーク
    Power plant mark.
    • Reminder, jika hatsuden 自家発電, "generation electricity at home," is a slang for "masturbation."

  • The asterisk is often likened to the anus, specially of cats, because of its sphincter-like shape.
  • sei no ji
    正の字
    The 正 character.
Kitagawa Marin 喜多川海夢 cosplaying as a lewd character, with tally marks written on her thighs that likely symbolizes the number of times she's had sex in an orgy (each 正 equals 5, so 17 times).
Character: Kitagawa Marin 喜多川海夢
Manga: Sono Bisque Doll wa Koi wo Suru, その着せ替え人形ビスク・ドールは恋をする (Episode 5)
  • Context: it's a trope to write tally marks on thighs (or other body parts) to count how many times a girl had sex in an orgy. Here, Marin is cosplaying as a character from an erotic game, and the tally marks on her thighs are part of the cosplay.
  • niku
    "Meat."
    • The word nikubenki 肉便器, literally "meat urinal," is a degradatory term often used in body writing.
    • However, niku 肉, specially when written on one's forehead, is a reference to the manga Kin'niku-man キン肉マン, and its protagonist, which has niku 肉 written on its forehead.
