What are sentence-ending particles in Japanese?

In Japanese, sentence-ending particles are little words that appear at the end of a sentence and imply something about what the speaker is trying to accomplish by speaking. Using a sentence-ending particle might help clarify whether a phrase like “You eat tuna” is a command (“You, eat tuna!”), a question (“You eat tuna?”), a request for confirmation (“You eat tuna?”), or something else.

In this brief introductory post, we’ll introduce you to the main Japanese sentence-ending particles and direct you to some resources where you can see each of them examined in a lot more depth. Then we’ll talk a little about the role of sentence-ending particles in Japanese more generally. Let’s have a look!

The most common sentence-ending particles in Japanese are listed below, along with a very brief summary of their meanings. However, many of these particles have a number of functions and restrictions, so if you want to really master them, you’ll want to follow the links to learn more!

• よ[yo] indicates that your sentence is specifically tailored to the listener. You can use it in a wide range of circumstances, such as warning someone, providing new immediately helpful information, or giving a command.

  あっ、忘れ物ですよ。➚

  A, wasuremono desu yo.➚

  Oh, you forgot something!

• ね[ne] is used to “check in” with the listener, looking to build empathy or check that your understanding is correct.

  パーティーは土曜日ですね？➚

  Pātii wa doyōbi desu ne? ➚

  The party is on Saturday, right?

• よね[yo ne] is used like ね[ne], in a case where you’re a bit less certain your understanding is correct.

  ねえ、戸締まりちゃんとしてくれたよね。➚

  Nē, tojimari chanto shite kureta yo ne.➚

  Say, you did lock up the place as I asked, right?

• か[ka] is a question particle: used to mark questions. Questions don’t always just ask for information though, so か[ka] can be used to make requests, express doubt, and more.

  学生さんですか。➚

  Gakusei-san desu ka.➚

  Are you a student?

• かな[kana] indicates that you have doubts about what you’re saying. Sentences with this particle can sometimes function as questions.

  この豆腐、まだ大丈夫かな。➙

  Kono tōfu, mada daijōbu kana.➙

  I wonder if this tōfu is still OK.

• かしら[kashira] is used a lot like かな[kana], except that it is used almost exclusively by female speakers, and is not much used in day-to-day speech.

  佐藤さん、ほんとに来てくれるかしら。➙

  Satō san, honto ni kite kureru kashira.➙

  I wonder if Ms. Sato will really come for us.

• っけ[kke] indicates that you aren’t certain of your memory about something. This can be used to ask for confirmation of something too.

  スマホ、どこに置いたっけ。➙

  Sumaho, doko ni oitakke.➙

  Where on earth did I put my smartphone?

• なあ[nā] is used primarily to express emotion upon discovering or remembering something, usually when you’re speaking to yourself.

  ああ、桜がきれいだなあ。➘

  Ā, sakura ga kirei da nā.➘

  Ah, the cherry blossoms are beautiful!

• の[no] is used primarily when making requests and providing explanations, and has historically mostly been used by female speakers and children.

  Mother:

  どうして起きないの？➚

  Dōshite okinai no?➚

  Why aren’t you getting up?

  Child:

  お腹が痛いの。➙

  Onaka ga itai no.➙

  (Because) my tummy hurts.

• もん[mon] is mostly used by children or young women to give an explanation to someone on whom they are dependent.

  にんじん、嫌いなんだもん。➙

  Ninjin, kirai nanda mon.➙

  Because I don’t like carrots.

• わ[wa] is used to add a light-hearted tone when making a decision or asserting something. It’s considered very feminine and is being used less-and-less in modern speech.

  私の方からお電話しますわ。➚

  Watakushi no hō kara odenwa shimasu wa.➚

  I’ll call you.

• な[na] is used primarily in harsh commands and prohibitions, most often made by male speakers.

  おい、家の中であばれるな。➙

  Oi, ie no naka de abareru na. ➙

  Hey, don’t play rough in the house!

• ぞ[zo] is used to show the speaker’s strong will or opinion, and is used mostly by male speakers.

  今日の試合は絶対勝つぞ。➙

  Kyō no shiai wa zettai katsu zo.➙

  I’ll definitely win today’s game!

• かい[kai] is an old-fashioned question marker, mostly used when older people, particularly men, address younger people.

  凧の揚げ方、知ってるかい。➚

  Tako no agekata, shitteru kai?➚

  Do you know how to fly a kite?

• さ[sa] is used primarily to add a brusque tone to comments made by male speakers.

  四年も勉強すれば、これくらい読めて当然さ。➙

  Yonen mo benkyō sureba, korekurai yomete tōzen sa.➙

  Of course I can read this after four years of study.

Sentence-ending particles in Japanese are used to clarify why the speaker is talking, and sometimes what kind of reaction they want out of the listener. Here are some important considerations to keep in mind:

• Some sentence-ending particles are gendered, meaning that they are, or historically were, used mostly either by male or by female speakers. (Check out our post on gendered sentence-enders to learn more about some of the most gendered sentence-endings!)

• Most sentence-ending particles have a range of different uses. You can read the articles linked above for some examples, but you’ll need to observe how native speakers use these words to really master them.

• Remember that the intonation you use (or the “pitch” of your voice) can impact how a sentence-ending particle is interpreted. As you read our articles, pay close attention to the arrows we add to the examples, which indicate whether you should use a rising, falling, or flat intonation pattern.
