Sun in Japanese is 太陽 (taiyou), and the single character behind it is 日 (hi), four strokes descended from a pictograph of a disc with a dot at its center. Japanese keeps the two apart. 日 does most of its daily work meaning “day,” while 太陽 is the sun itself, the body burning in the sky.
Sun in Japanese
The ordinary word for the sun is 太陽 (taiyou), written with two kanji and used in weather reports, textbooks, and conversation alike. The character 日 is read hi on its own and nichi or jitsu inside compounds, but in running text it almost always means “day,” as in 今日 (kyou, today).
The Kanji for Sun: 日
- Character: 日
- On’yomi: ニチ (nichi), ジツ (jitsu)
- Kun’yomi: ひ (hi), か (ka)
- Stroke count: 4
- General meaning: sun, day, date, and Japan itself in compounds
- Radical: 日 is itself a radical, number 72, and it turns up inside 明 (bright), 時 (time), 春 (spring), and 早 (early)
The second character in 太陽 is 陽 (you), twelve strokes, built from the mound radical 阝 with the sun element on the right. On its own it means sunshine and the yang half of the yin and yang pair. 太 means great or thick. So 太陽 reads literally as “the great yang,” the biggest source of light there is.
Japanese Symbol for Sun
The oldest forms of 日 were a circle with a mark inside it, a sun with something at its heart. Writing on bone and then on paper squared the circle off, which is why the modern character is a rectangle with one bar across the middle. It is the plainest picture in the writing system and one of the first characters a Japanese child learns.
That plainness gives 日 enormous reach. Set it beside 月 (moon) and you get 明 (mei, bright), light doubled. It sits at the foot of 春 (haru, spring) and at the left of 時 (ji, time), which is a fair summary of what a sun does: it warms and it measures. The character behaves less like a word than like a unit of meaning that other characters get assembled around.
How to Write Sun in Japanese
日 takes four strokes and follows the box rule rather than the usual horizontal-first rule. The left vertical comes down first. The second stroke runs across the top and turns sharply down the right side in one movement. The third stroke is the short bar through the middle. The fourth closes the bottom.
Keep the box a little taller than it is wide. A 日 drawn square starts to look like 口 (kuchi, mouth) with a line in it, and a 日 drawn too wide reads as 目 (me, eye) missing a bar. The interior spaces above and below the middle stroke should be equal.
How to Say Sun in Japanese
太陽 has four beats: ta-i-yo-u. English speakers can get very close with “tah-ee-yoh,” holding that last vowel for two counts rather than clipping it. There is no heavy stress; Japanese distributes weight evenly across the syllables. 日 as hi sounds like the English word “he” cut short. As nichi it is “nee-chee,” and as jitsu it is “jee-tsoo” with the u barely voiced.
Five sentences you can actually use:
- 太陽が昇る。(Taiyou ga noboru.) The sun rises.
- 今日は太陽がまぶしいですね。(Kyou wa taiyou ga mabushii desu ne.) The sun is dazzling today, isn’t it.
- 日の出を見に行きました。(Hinode o mi ni ikimashita.) I went to see the sunrise.
- 太陽の光が窓から入ってくる。(Taiyou no hikari ga mado kara haitte kuru.) Sunlight comes in through the window.
- 日曜日は休みです。(Nichiyoubi wa yasumi desu.) Sunday is a day off.
Words and Compounds With 日

The ka reading shows up in counted days: 三日 (mikka) is the third of the month, or three days. And 太陽 has its own family, including 太陽系 (taiyoukei, the solar system) and 太陽光 (taiyoukou, solar light). The first sunrise of the new year gets its own observance, hatsuhinode.
The Sun in Japanese Culture
Japan is named after this character. 日本 (Nihon or Nippon) means “origin of the sun,” a name that makes sense from the mainland, where the islands sit to the east. “Land of the Rising Sun” is a translation of that idea rather than a poetic flourish.
The national flag is called the 日の丸 (hinomaru), the sun circle, formally the 日章旗 (nisshouki). It flew unofficially from 1870 and was only given legal status by the Act on National Flag and Anthem in August 1999. During the war years the government pushed the 日の丸弁当 (hinomaru bentou), a lunch box of plain white rice with a single red pickled plum in the middle, austerity dressed up as patriotism.
Behind all of it sits 天照大御神 (Amaterasu Oomikami), the sun goddess of Shinto myth and the ancestor claimed by the imperial line. She is enshrined at Ise, and the sun she stands for is a giver rather than a scorcher.
The Sun Kanji as a Tattoo
日 is the simplest character in this set to draw and the hardest to make interesting. Four strokes forming a closed rectangle read as clean and geometric, but they also read as plain, and at small sizes the enclosed space can fill in as ink settles. Give it room.
Know that it says “day.” An isolated 日 will read to most Japanese people as a date field before it reads as the sun. If the sun is the point, 太陽 (taiyou) is unambiguous, 陽 (you) is the graceful single character for sunlight, and 旭 (asahi, 6 strokes) means the rising sun specifically.
Mind the look-alikes. 目 (me, eye) is the same rectangle with two interior bars instead of one, and 白 (shiro, white) is 日 with a short stroke added on top. One extra line changes the word entirely, so make sure your artist works from a clean typeset reference rather than tracing freehand.
One cultural caution. The rising sun ray motif, 旭日旗 (kyokujitsuki), is the wartime military flag and remains genuinely offensive in Korea and parts of China. A plain 日 or 太陽 carries none of that. A sun with radiating rays does.
The character is written identically in Japanese and Chinese, so there is no script decision to make. Confirm with a native speaker before you ink.

FAQ
How do you say sun in Japanese?
The sun is 太陽 (taiyou), pronounced roughly “tah-ee-yoh” across four beats. It is the normal word in speech and writing. The single kanji 日 (hi) also means sun, but on its own it usually reads as “day,” so 太陽 is the safer choice when you mean the star itself.
What is the Japanese symbol for the sun?
The symbol is 日, a rectangle with one bar through the middle, originally a drawing of a disc with a dot at its center. It is radical 72 and appears inside dozens of other characters. The red disc on the national flag, the 日の丸 (hinomaru), is the same idea rendered as an image.
What is the kanji for sun?
The kanji for sun is 日, read hi alone and nichi or jitsu in compounds. It has four strokes and covers sun, day, and date. For the sun as a celestial body Japanese uses 太陽 (taiyou), and for sunshine as warmth and light it uses 陽 (you).
How many strokes does 日 have?
Four. The left vertical is written first, then a single stroke that crosses the top and turns down the right side, then the short bar through the middle, then the bottom bar to close the box. It follows the same rule as 口 (kuchi, mouth), which takes three strokes rather than four.
What is the difference between 日 and 太陽?
日 is the character for sun but functions as “day” or “date” in most ordinary text, as in 毎日 (mainichi, every day). 太陽 (taiyou) is the specific noun for the sun in the sky and is never mistaken for a calendar term. If you want the star, write 太陽.
Why is Japan called the Land of the Rising Sun?
Because 日本 (Nihon) literally means “origin of the sun.” The name was framed from the perspective of the Asian mainland, where the Japanese islands lie to the east and the sun appears to come up over them. The same character stands in for the country in words like 日系 (nikkei, of Japanese descent).
