Dark in Japanese is 闇, said yami, for darkness as a thing. For dark as a description you want a different character: 暗い (kurai). 闇 is seventeen strokes, built from 門 (gate) with 音 (sound) inside it. The on’yomi are アン (an) and オン (on). Written in hiragana it is やみ, and in katakana ヤミ.
Dark in Japanese
Dark in Japanese splits in two, and choosing wrongly is the mistake almost everyone makes here.
闇 (yami) is a noun. It is the dark, darkness itself, the thing you walk into. It also carries a second family of meanings that surprises people: hidden, secret, illicit. 闇市 (yamiichi) is a black market and 闇取引 (yamitorihiki) is a shady deal. In Japanese, what is dark is also what is off the books.
暗い (kurai) is an adjective. It is what you say about a room, a street, a colour, or a mood. 部屋が暗い (heya ga kurai), the room is dark. You cannot use 闇 in that sentence. The character behind it, 暗, also supplies 暗黒 (ankoku, darkness as a state), 真っ暗 (makkura, pitch black), and, less obviously, 暗記 (anki, memorisation, learning something in the dark of your head).
So: 闇 for the dark as a place or a condition, 暗 for dark as a quality. Both characters are read kurai in some contexts, which is why dictionaries list 闇い as a rare variant, but in real writing 暗い is the adjective and 闇 is the noun.
The Kanji for Dark: 闇
- Character: 闇

- Radical: 門 (gate), Kangxi radical 169, called もんがまえ (mongamae), the gate enclosure
Japanese Symbol for Dark
闇 is a phono-semantic compound, and the two halves do very different jobs.
門 is a gate, and it is the meaning half. The character is a picture: two leaves of a double door, one on each side, drawn with their posts and crosspieces. It encloses whatever sits inside it, and everything it encloses has something to do with gates, doorways, or thresholds. 間 (ma, an interval, a gap) is the sun seen through a gate. 開 (hiraku, to open) and 閉 (shimeru, to close) are the doors working.
音 sits inside, and it is the sound half. It means sound or noise, and here it is purely phonetic: it supplied the pronunciation an. It is not telling you anything about darkness.
But the arrangement is hard to unsee. A gate with sound shut inside it, and no light. That reading is not the etymology, and it would be dishonest to present it as one. It is worth mentioning only because the character does look like what it means, which is rarer than people assume.
Contrast 暗, the adjective character, which is 日 (sun) beside the same 音. A sun that has gone quiet. Same phonetic, different frame.
How to Write 闇 in Japanese
Seventeen strokes, and the rule for enclosures governs everything: the frame first, the contents second.
門 takes eight. Write the left leaf first, top to bottom, then the right leaf, top to bottom. Each leaf is a vertical with its short marks and its turning stroke. The two should mirror each other and stand slightly apart, because everything else goes between them.
Then 音 inside, in nine strokes. The 立 element on top comes first, five strokes ending with its wide base horizontal, then 日 beneath it in four, frame before the interior line, closing stroke last.
Seventeen strokes inside one square is genuinely dense. The 日 at the bottom of 音 is the first compartment to fill in, and the gap between the gate posts and the element inside them is the first thing to disappear. If you are writing 闇 by hand, write it bigger than feels necessary.
How to Say Dark in Japanese
Yami is two even beats: “yah-mee.” The a is open as in “father,” the i is short as in “sit,” and neither beat takes stress. The adjective kurai is three beats, “koo-rah-ee,” with a tapped r.
Real sentences:
- 闇の中で何も見えない。(Yami no naka de nani mo mienai.) I cannot see anything in the dark.
- 部屋が暗いです。(Heya ga kurai desu.) The room is dark.
- 外はもう真っ暗だ。(Soto wa mou makkura da.) It is already pitch black outside.
- 夕闇が迫ってきた。(Yuuyami ga sematte kita.) Dusk was closing in.
- 闇市で売られていた。(Yamiichi de urarete ita.) It was being sold on the black market.
Words and Compounds With 闇
- 暗闇 (kurayami): darkness, the dark. Both characters at once, and the most common word for pitch darkness.
- 夕闇 (yuuyami): dusk, the darkness that arrives in the evening.
- 宵闇 (yoiyami): twilight, the early part of the night. A softer, more literary word than 夕闇.
- 闇市 (yamiichi): a black market.
- 闇取引 (yamitorihiki): a shady deal, an under-the-counter transaction.
- 闇討ち (yamiuchi): an attack made under cover of darkness, an ambush.
- 闇雲 (yamikumo): reckless, haphazard, at random. Literally dark clouds, and used of acting blindly.
- 暗黒 (ankoku): darkness as a total state, as in a dark age.
- 真っ暗 (makkura): pitch black.
- 暗記 (anki): memorisation, learning by heart.
The split shows clearly in that list. Words about the dark as a place or a cover use 闇. Words about dark as a measurable quality use 暗. And 闇 keeps drifting toward the illicit, because a thing done in the dark is a thing done where nobody is looking.
Dark in Japanese Culture
Japanese aesthetics does not treat darkness as an absence to be corrected. It treats it as a material with its own properties, and much of the tradition is built on making a little light work inside a lot of dark: a single lamp in a tea room, gold leaf on a screen catching what light there is, a garden read at dusk.
That is the ground yugen grows in, the sense of profound depth in what is only half seen. Something withheld reads as deeper than something displayed, and darkness is the mechanism that withholds.
The other register is the frightening one, and Japan has an unusually rich vocabulary for it. Yurei, the returning dead, belong to the dark, and traditional ghost stories are told in summer for the specific purpose of chilling a listener through a hot night. 百物語 (hyakumonogatari) was the Edo-period game of telling a hundred tales by candlelight, extinguishing one candle after each, with the last of them left unspoken.
In modern Japanese, 闇 has become one of the most heavily used characters in the vocabulary of anime, manga and games, where it names dark power, a dark side, or a hidden faction. That usage is genuine and everywhere, and it is worth knowing because it means a Japanese reader under forty meeting 闇 out of context may well think of fiction first. The word also has a current social sense: 闇バイト (yami baito), a shady job advertised online, has been a real and widely reported problem in Japan.
As a Tattoo
闇 is a striking character and an increasingly requested one, and it works, with conditions.
The first is that it says darkness as a noun, not dark as a description. If what you want is dark as a quality or a mood, that is 暗, and 闇 does not do that job. The second is the illicit register. 闇 genuinely carries black market, shady, and under-the-counter, and a Japanese reader sees that meaning alongside the poetic one rather than instead of it. It is not a dealbreaker, but you should know it is there.
The third is the fiction association. Because 闇 is so common in anime and game titles, a single 闇 on skin reads to many Japanese people as a reference to that world. Some people want exactly that. Others are surprised by it.
Do not extend it. 闇討ち (yamiuchi) is an ambush, 闇市 (yamiichi) is a black market, and 闇雲 (yamikumo) means acting blindly. Any character added to 闇 produces a real dictionary word, and the words in its neighbourhood are unusually loaded.
On script: 闇 is written identically in Japanese and traditional Chinese. Simplified Chinese uses a simplified gate form for this character and in practice writes darkness as 暗 instead, so a reference image using the simplified gate is not the Japanese form. For correct Japanese, 闇 with the full 門 is what you want.
Seventeen strokes is a great deal of ink in one square. The interior of 音 fills in as the ink settles, and a small 闇 will eventually read as a solid gate with a smudge in it. This character needs size, a confident hand, and open spacing. Forearm, calf, and back all give it room; fingers and wrists do not.

FAQ
How do you say dark in Japanese?
It depends which dark you mean. Darkness as a thing is 闇 (yami), two beats, “yah-mee.” Dark as a description is the adjective 暗い (kurai), three beats, “koo-rah-ee,” and that is what you use for a dark room or a dark colour. 部屋が暗いです means the room is dark.
What is the kanji for dark?
The kanji for darkness is 闇, seventeen strokes, made of 門 (gate), Kangxi radical 169, enclosing 音 (sound), which supplies the pronunciation. For dark as an adjective the character is 暗, which puts the same 音 beside 日 (sun). Its readings are やみ (yami), アン (an), and オン (on).
What is the Japanese symbol for dark?
闇 is the written symbol for darkness. The gate around it is a picture of a double door, and the 音 inside supplies only the sound, not the meaning. The resemblance to a gate with the light shut out is a coincidence rather than an etymology, though a memorable one.
How do you write yami in Japanese?
闇 is the kanji and the standard written form. やみ is hiragana and ヤミ is katakana, and katakana is common in titles and in the modern slang sense of something shady. Remember that the adjective dark is written 暗い (kurai). Our guide to hiragana vs katakana explains the split.
Is 闇 the same character in Chinese?
Not quite. 闇 is identical in Japanese and traditional Chinese, but simplified Chinese uses a simplified gate form, and in everyday Chinese darkness is normally written 暗 rather than 闇. If your reference shows a simplified gate, it is not the Japanese form. The Mandarin reading is àn.
What is the difference between 闇 and 暗?
闇 (yami) is a noun: the dark, darkness, and by extension the hidden or illicit, as in 闇市 (yamiichi, black market). 暗 is the character behind the adjective 暗い (kurai), dark or dim, used of rooms, colours and moods. It also gives 暗黒 (ankoku, darkness) and 真っ暗 (makkura, pitch black).
