Kiss in Japanese: キス, チュー, 口くちづけ, and the anime classic 間接かんせつキス

"Kiss" in Japanese is キス (kisu), and "to kiss" is キスする. The cute, casual word is チュー (chuu), used with children, pets and between couples, and the poetic word is 口くちづけ (くちづけ). In anime, the most famous kiss is not a kiss at all: 間接かんせつキス, the "indirect kiss" of sharing a drink.

Japanese has a whole range of kiss words, from childish to literary, and the choice changes the mood completely. A grandmother asking a toddler for ほっぺにチュー and a novel describing a 口くちづけ under the moon are talking about the same act in very different voices. This post covers the words, the useful phrases, a bit of culture, and why anime characters blush over a shared straw.

How do you say "kiss" in Japanese?

What is the basic word?

キス (kisu) is the standard word, from English. "To kiss" is キスする or キスをする.

二人ふたりはキスした。 — The two of them kissed. (neutral) 映画えいがのキスシーンがきれいだった。 — The kiss scene in the movie was beautiful. (casual)

It works in conversation, writing and news. You can also say who you kiss with に or と: 彼かれにキスした (I kissed him), 彼かれとキスした (we kissed). に points at the person; と makes it mutual.

What is チュー?

チュー (chuu) is a cute, casual "kiss", from the sound of a kiss. It is used with children, pets, and playfully between couples.

ほっぺにチューして。 — Give me a kiss on the cheek. (casual, cute, a parent to a child) 猫ねこにチューした。 — I kissed my cat. (casual, playful)

チュー is warm and a little silly, which is exactly why it is used with kids and pets. Between adults it sounds playful rather than serious. In song lyrics you will also see the sound written ちゅっ or チュッ.

What are the formal and poetic words?

口くちづけ (くちづけ) is poetic and soft; 接吻せっぷん (せっぷん) is old-fashioned and formal.

月つきの下したで、静しずかに口くちづけをした。 — Under the moon, they shared a quiet kiss. (written, romantic novel style)

口くちづけ appears in novels, song lyrics and dramatic anime lines. 接吻せっぷん sounds like an old translation or a literary classic, and is rarely used in speech today. In everyday conversation, キス is the safe word.

Beyond the basics

What is 間接かんせつキス?

間接かんせつキス (かんせつキス), "indirect kiss", is drinking from the same cup, can or straw as someone else, so your lips touch where theirs did.

それ、間接かんせつキスじゃない? — Isn't that an indirect kiss? (casual, teasing)

It is one of the most famous anime and manga tropes: a character offers a drink, the other notices, and both blush. In real life, adults rarely make a fuss about it, but teenagers might tease each other with it. It is a good example of how anime turns small social moments into big emotional ones.

What is 投なげキス?

投なげキス (なげキス), "a thrown kiss", is blowing a kiss.

ステージから投なげキスをした。 — She blew a kiss from the stage. (neutral, idols and performers)

Idols do it at concerts, and fans love it. In everyday life between friends, it would be playful or joking.

What is a ファーストキス?

ファーストキス is "first kiss", a common phrase in romance manga, songs and conversation.

ファーストキスはレモンの味あじ? — Does a first kiss taste like lemon? (casual, a famous old romance cliché)

The idea that a first kiss tastes like lemon is an old Japanese pop-culture cliché, and characters still joke about it. 初はつキス (はつキス) means the same thing and is a bit more casual.

Is kissing common in Japanese culture?

Kissing is not part of Japanese greetings. People bow or wave instead, and cheek kisses between friends are not a custom.

日本にほんでは、あいさつでキスはしません。 — In Japan, people don't kiss as a greeting. (polite, explaining culture)

Public displays of affection are also fairly reserved in Japan, so a couple kissing on a busy street would draw some looks. This is useful to know if you come from a culture where greeting kisses are normal: a bow or a smile is the Japanese default. Our post on hello in Japanese covers greetings.

How do you talk about kissing in a relationship?

The usual phrases are キスする, and for asking, キスしてもいい? "Can I kiss you?"

キスしてもいい? — Can I kiss you? (casual, gentle, between partners)

〜てもいい? is the standard way to ask permission. Our post on asking permission with 〜てもいいですか explains the pattern.

Is there anything else called キス?

Yes: キス is also a small white fish, the sillago, written 鱚きす in kanji. It is often eaten as tempura.

キスの天てんぷらがおいしい。 — The sillago tempura is delicious. (casual, at a tempura restaurant)

So if you see キス on a menu, it is not a romantic dish. Context makes it clear.

Common mistakes

  • Using 接吻せっぷん in conversation. It sounds like an old novel. Use キス.
  • Using チュー in a serious romantic moment. It is cute and playful; it can break the mood.
  • Kissing friends on the cheek as a greeting in Japan. It is not a local custom; a bow or a wave is normal.
  • Confusing に and と. 彼かれにキスした is "I kissed him"; 彼かれとキスした is "we kissed".
  • Ordering キス expecting something romantic. On a menu, it is a fish.
