Japanese Punctuation: Everything You Need to Know

---

Japanese punctuation includes familiar ideas such as full stops, commas and quotation marks, but the symbols and spacing do not always work like their English counterparts.

This guide covers the marks you will meet most often, how they behave in horizontal and vertical text, and a few Japanese symbols that look like punctuation but have a different job.

Japanese Punctuation: 約物 (yakumono)

The Japanese typography term 約物 (yakumono) covers punctuation marks, brackets and several other symbols used in written text. Some marks change orientation in vertical writing, but modern layout software normally handles that for you.

Japanese punctuation was not suddenly introduced in 1946. Marks that helped readers divide text existed centuries earlier, and the modern distinction between 。 and 、 became a schoolbook standard after a Ministry of Education draft in 1906. The ministry's 1946 guide expanded that earlier draft into general guidance for contemporary writing.

Usage still varies by publisher, genre and context, especially with question marks, exclamation marks and brackets. The sections below give you the common modern patterns without pretending that every editor follows one universal house style.

Japanese Period Punctuation: 句点 (kuten), まる (maru)

The Japanese full stop is 。. Its formal name is 句点 (kuten), while まる (maru, “circle”) is a common everyday name.

It usually ends a sentence just as a full stop does in English. Do not type a separate space after it in ordinary Japanese text. The character's width and the surrounding spacing are part of the type layout, rather than a hidden word space.

Example:
名前はケイトリンです。
Namae wa Keitorin desu.
“My name is Caitlin.”

Japanese Quotation Marks: 「」 and 『』

The corner brackets 「」, called かぎ括弧 (kagi kakko), commonly mark quotations and dialogue. They can also single out a word or title, depending on the publication's style.

The double corner brackets 『』, called 二重かぎ括弧 (nijū kagi kakko), are not simply English single quotation marks used backwards. They can mark a quotation inside 「」, and they are also commonly used around the titles of books, magazines and other works.

For example:
先生は「毎日『雪国』を読んでください」と言いました。
Sensei wa “Mainichi ‘Yukiguni’ o yonde kudasai” to iimashita.
“The teacher said, ‘Please read Snow Country every day.’”

In vertical text, the same brackets rotate and move with the writing direction. You do not need to choose a separate pair of characters.

Japanese Comma: 読点 (tōten)

The Japanese comma is 、, formally called 読点 (tōten). It separates clauses, list items or parts of a sentence where a pause helps the reader.

Japanese comma placement is more flexible than English comma placement, but it is not random. Use it to make the sentence structure clear, and do not add an ordinary space after it.

Example:
昨日は忙しかったので、今日は行くよ。
Kinō wa isogashikatta node, kyō wa iku yo.
“Since I was busy yesterday, I'll go today.”

Japanese Question Mark: 疑問符 (gimonfu)

A Japanese question can end with 。 when its grammar already makes the question clear, often through the particle か (ka):

何歳ですか。
Nansai desu ka.
“How old are you?”

Modern Japanese also uses the full-width question mark ？, called 疑問符 (gimonfu) or informally はてなマーク (hatena māku). It is common in dialogue, advertising and digital writing, and editors may also use it where it makes the questioning tone clearer. It is not restricted to manga or social media.

Example:
この料理、おいしい？
Kono ryōri, oishii?
“Is this dish tasty?”

Do not put an ordinary space before ？. Spacing after a sentence-ending question mark depends on the medium and house style.

Japanese Exclamation Mark: 感嘆符 (kantanfu)

The full-width exclamation mark is ！. Its formal name is 感嘆符 (kantanfu), and ビックリマーク (bikkuri māku) is a common informal name.

It can show excitement, surprise or emphasis, especially in dialogue and informal writing. More formal prose may use it sparingly. Do not add 。 after a sentence-ending ！.

Example:
来週末を楽しみにしてる！
Raishūmatsu o tanoshimi ni shiteru!
“I'm looking forward to next weekend!”

Japanese Brackets and Parentheses: 括弧 (kakko)

Japanese has several kinds of 括弧 (kakko, brackets or parentheses). In Japanese text, these normally use full-width forms:

• （）: 丸括弧 (maru kakko), round brackets or parentheses
• ［］: 角括弧 (kaku kakko), square brackets
• ｛｝: 波括弧 (nami kakko), curly brackets
• 【】: 隅付き括弧 (sumitsuki kakko), lenticular brackets
• 〈〉: 山括弧 (yama kakko), angle brackets

（） often add explanations much as English parentheses do. The other pairs are not freely interchangeable: a publisher may use 【】 for labels or emphasis, while 〈〉 and other brackets follow the document's chosen style. Consistency matters more than trying to give every pair one fixed English equivalent.

The Japanese Particle の (no): Not Punctuation

English often uses an apostrophe and s to mark possession, but Japanese does not replace that punctuation with another mark. の (no) is a grammatical particle, not punctuation.

It links one noun to another and can express possession, affiliation or a broader “of” relationship:

私の犬
Watashi no inu
“My dog”

大学の学生
Daigaku no gakusei
“A university student”

You can learn its other uses in this guide to Japanese particles.

The Japanese Interpunct: 中黒 (nakaguro)

The middle dot ・ is called 中黒 (nakaguro) or 中点 (nakaten). It often separates parts of foreign names and loanwords written in katakana:

ケイトリン・サカサス
Keitorin Sakasasu
“Caitlin Sacasas”

It can also divide parallel items, as in 赤・緑・青 (aka, midori, ao, “red, green and blue”), or make the boundaries in an unfamiliar expression easier to see. Its exact use varies, so it is better to think of it as a visual separator than as a direct replacement for the English slash.

The Japanese Wave Dash: 波ダッシュ (nami dasshu)

The wave dash is 〜, called 波ダッシュ (nami dasshu). It commonly marks a range:

• 9時〜17時: 9:00–17:00
• 東京〜大阪: Tokyo to Osaka

In informal writing it can also stretch a sound or soften the tone, as in そうだね〜 (sō da ne, “Yeah, that's right”). It does not stand in for a colon.

You may also see the full-width tilde ～ in digital Japanese. It is a different Unicode character from the wave dash 〜, although fonts and Japanese input systems often make the two look or behave alike. If you are working with searchable text or data, that distinction is worth remembering.

Japanese Ellipses: 三点リーダー (santen rīdā)

The ellipsis character … is called 三点リーダー (santen rīdā). A single … is common on screens, while edited Japanese books often use a pair, …….

As in English, an ellipsis can show an omission, a pause or a thought trailing off. Manga and dialogue use it frequently for silence and hesitation, but it is still a punctuation mark rather than a row of three Japanese full stops.

Marks That Are Not Japanese Punctuation

Several Japanese marks can look like punctuation to an English-speaking learner, but they change pronunciation or repeat a character instead.

The long-vowel mark ー is called 長音符 (chōonpu). It is not a dash. It usually extends the preceding vowel in katakana words:

• デパート, depāto, “department store”
• ジョーカー, jōkā, “joker”

These other marks are useful to recognise too:

• Dakuten ゛: these two strokes attach to kana in the k, s, t and h rows to produce the corresponding g, z/j, d and b sounds.
• Handakuten ゜: this small circle attaches to kana in the h row to produce a p sound.
• Small っ or ッ, called 促音 (sokuon): this marks a following geminate consonant, often shown by doubling that consonant in rōmaji, as in きって (kitte, “postage stamp”).
• 々, called 同の字点 (dō-no-jiten): this iteration mark repeats the preceding kanji. It appears in words such as 人々 (hitobito, “people”) and 色々な (iroiro na, “various”).

For a fuller introduction to these sound changes, see the guide to hiragana and katakana.

Japanese Spacing and Full-Width Characters

Ordinary Japanese does not put spaces between words. Full-width Japanese characters are normally laid out on an em-square grid, and punctuation has its own character width and side spacing within that system. This does not mean that the keyboard inserts a literal space after every mark.

Write 私は30歳です。 without adding spaces around 。 or between the Japanese words. Full-width digits such as ３０ also exist, but both digit styles can appear in Japanese; the choice depends on the document and its layout.

Japanese typesetting also uses line-breaking rules called 禁則処理 (kinsoku shori) so that a line does not begin with marks such as 。 or 、. Your browser, word processor or publishing software usually applies those rules automatically.

How to Type Japanese Punctuation

The easiest option is to enable a Japanese input method on your phone or computer. Common punctuation keys then produce Japanese forms, and you can type a mark's Japanese name, such as kakko or nakaguro, and use conversion to choose the character you need. The exact shortcut varies by operating system, keyboard layout and input method.

If you need the Unicode code points for a document or website, these are the main ones from this guide:

• 、 U+3001 IDEOGRAPHIC COMMA
• 。 U+3002 IDEOGRAPHIC FULL STOP
• 「 U+300C and 」 U+300D CORNER BRACKETS
• 『 U+300E and 』 U+300F WHITE CORNER BRACKETS
• 〜 U+301C WAVE DASH
• ・ U+30FB KATAKANA MIDDLE DOT
• ー U+30FC KATAKANA-HIRAGANA PROLONGED SOUND MARK
• ！ U+FF01 FULLWIDTH EXCLAMATION MARK
• ？ U+FF1F FULLWIDTH QUESTION MARK
• … U+2026 HORIZONTAL ELLIPSIS

Use Japanese Punctuation with Confidence

You do not need to memorise every bracket name before you start reading. Begin with 。, 、, 「」, ？ and ！, then notice how native material uses the middle dot, wave dash and ellipsis.
