Summer in Japanese is 夏, said natsu. Ten strokes, and unusually for a common kanji it has three on’yomi: カ (ka), ガ (ga), and ゲ (ge). Its radical is 夊, the “go slowly” element at the foot of the character. Written in hiragana it is なつ, and in katakana ナツ.
Summer in Japanese
Summer in Japanese is 夏 (natsu), and that single word is what people say. It sits in the set with 春 (haru, spring), 秋 (aki, autumn), and 冬 (fuyu, winter), and the four together make 春夏秋冬 (shunkashuutou), the four seasons as a single word.
The readings split by register. Natsu is the everyday one and covers almost everything you will say out loud. カ (ka) does the formal and written work: 夏季 (kaki, the summer season), 初夏 (shoka, early summer), 盛夏 (seika, high summer). ゲ (ge) is rare and worth knowing for exactly one important word, 夏至 (geshi), the summer solstice.

Japanese Symbol for Summer
夏 is a character with a picture inside it, though scholars hedge on the details, so it is worth stating what is agreed and what is not.
The bulk of the character is a person. The block filling the top is what survives of 頁, the head element that also sits in 顔 (kao, face) and 題 (dai, topic), with its two small legs trimmed off. The 夊 at the bottom is a foot, the element that elsewhere marks slow or trailing movement. So the modern shape is a head above a foot: a figure walking.
The leading reading of the oldest oracle bone form adds one more piece. It is analysed as 日 (sun) over 頁 (head, man), a person under a scorching sun, which is as neat an image of summer as you could ask for. The catch is that the identification is uncertain, since the character appears in those earliest texts only as a diviner’s name. The sun dropped out of later forms and the foot was added, which is how the character arrived at its present shape.
So the honest version is this: there may well be a sun in the origin of 夏, and there is definitely a person walking in the character you write today. What there is not is a straight line between the drawing and the season, and anyone claiming one is filling in a gap the evidence leaves open.
How to Write 夏 in Japanese
Ten strokes, top to bottom, with the trailing foot last.
Start with the short horizontal at the very top. Then the six strokes of the block below it, which is 自 in shape: the short slanting stroke at its peak, then the frame, then the two horizontals inside, then the closing line at the base. That block should stay compact and rectangular. It carries most of the character’s weight and all of its density.
The last three strokes are 夊 at the foot. A short stroke slanting down to the left, a small stroke crossing it, then the long sweep that runs down and out to the right and lifts at the end. That final stroke is the one that gives 夏 its motion, and it should extend well past the block above it.
If the bottom sweep is cut short, 夏 looks stunted. If the upper block is drawn too wide, the sweep has nowhere to go. The character wants a narrow top and a generous foot.
How to Say Summer in Japanese
Natsu is two even beats: “nah-tsoo.” The ts is a single sound, as in “cats,” not two. The u at the end is short and lightly voiced, close to being swallowed. No stress on either beat.
Real sentences:
- 夏が好きです。(Natsu ga suki desu.) I like summer.
- 日本の夏は暑いです。(Nihon no natsu wa atsui desu.) Japanese summers are hot.
- 夏休みに海へ行きました。(Natsuyasumi ni umi e ikimashita.) I went to the sea during the summer holidays.
- 今年は夏バテしました。(Kotoshi wa natsubate shimashita.) The summer heat wore me out this year.
- 夏祭りに浴衣を着ます。(Natsumatsuri ni yukata o kimasu.) I wear a yukata to the summer festival.
Words and Compounds With 夏
- 夏休み (natsuyasumi): the summer holidays, school or work.
- 真夏 (manatsu): the height of summer, midsummer.
- 初夏 (shoka): early summer.
- 盛夏 (seika): high summer, the peak of the heat.
- 夏至 (geshi): the summer solstice, and the one everyday word that uses the ゲ reading.
- 立夏 (rikka): the first day of summer in the traditional calendar, around 6 May.
- 夏祭り (natsumatsuri): a summer festival.
- 夏バテ (natsubate): summer fatigue, the flattened feeling that comes with weeks of heat and humidity.
- 常夏 (tokonatsu): everlasting summer, used of tropical places.
- 夏服 (natsufuku): summer clothes, and specifically the lighter school or work uniform swapped in for the season.
夏バテ is the one to keep. It is written with the kanji plus katakana, it is used constantly from July onward, and it describes something English needs a whole clause for: not illness, not tiredness exactly, but the specific depletion of a Japanese summer.
Summer in Japanese Culture
Japanese summer is the most densely scheduled season of the year, and almost all of it happens after dark.
夏祭り are the frame. Neighbourhood shrine festivals fill July and August with food stalls, drums, and 盆踊り (bon odori), the circle dance held around a raised platform. People wear 浴衣 (yukata), the light cotton kimono kept for exactly this. 花火 (hanabi), fireworks, belong to the same season rather than to any national holiday, and the big riverside displays draw crowds in the hundreds of thousands.
At the centre of it sits Obon, the days when the spirits of the dead are said to come home. Most of Japan keeps it from 13 to 16 August, Tokyo and pockets of Tohoku and Hokuriku keep the older mid-July dates, and Okinawa still follows the lunar reckoning. Families clean graves, light fires to guide the ancestors in, and float lanterns to send them back. It is the one time the whole country moves at once, and trains and roads out of the cities fill for days.
Tanabata, the star festival, opens the season on 7 July in most places and in early August in Sendai. And the sensory shorthand for summer is remarkably fixed: the sound of 蝉 (semi), cicadas, the note of a 風鈴 (fuurin) wind chime in an open window, and かき氷 (kakigoori), shaved ice under coloured syrup.
Summer also sits inside the four-season set that organises so much of Japanese aesthetics. Spring in Japanese is 春 and belongs to the cherry blossoms; winter in Japanese is 冬. Autumn has its own leaf-viewing custom, momijigari, which is the mirror of hanami at the other end of the year.
As a Tattoo
夏 is a good choice for anyone marking a season, a place, or a particular year. The meaning is exact and uncontroversial, and the shape is more interesting than most single characters, with a compact head over that long trailing sweep.
Know what it says. 夏 means summer, the season. It does not mean warmth, freedom, or youth, all of which the English word can suggest. To a Japanese reader it is a calendar word, and paired with the right second character it becomes a specific one: 真夏 (manatsu) is the height of summer, 常夏 (tokonatsu) is everlasting summer and reads as tropical.
Watch the pairings. 夏バテ (natsubate) is summer exhaustion and would be an odd thing to wear. The season characters combine readily into real words, so anything added to 夏 will be read as one.
On script: 夏 is written identically in Japanese, simplified Chinese, and traditional Chinese. The form is safe everywhere, only the sound changes, from natsu to xià in Mandarin. The character also means the Xia dynasty in Chinese, which is a shade of meaning Japanese does not carry.
Ten strokes need a little room, mainly for the two horizontals inside the upper block. The bottom sweep is the character’s signature, so give it space to run and do not let a tight placement clip it. Forearm, ribs, and shoulder blade all work.

FAQ
How do you say summer in Japanese?
You say natsu, written 夏. Two flat beats, “nah-tsoo,” with the ts as one sound and no stress on either beat. That is the word for the season in ordinary speech. The on’yomi ka appears in written compounds such as 夏季 (kaki, summer season) and 初夏 (shoka, early summer).
What is the kanji for summer?
The kanji for summer is 夏, ten strokes. Its radical is 夊, the trailing-legs element, Kangxi number 35, which sits at the foot of the character. Its readings are なつ (natsu), カ (ka), ガ (ga), and ゲ (ge), the last of which appears in 夏至 (geshi, the summer solstice).
What is the Japanese symbol for summer?
夏 is the written symbol. The top of the modern character is what remains of 頁, a head, and the 夊 at the foot is a foot, so the shape is a walking figure. The oldest form is usually read as a person under a sun, though that identification is uncertain because the character appears there only as a name.
How do you write natsu in Japanese?
夏 is the kanji and the standard written form. なつ is hiragana, used in soft or casual writing and in given names. ナツ is katakana, seen in branding and product names. Our guide to hiragana vs katakana explains when each script fits.
Is 夏 the same character in Chinese?
Yes. 夏 is written identically in Japanese, simplified Chinese, and traditional Chinese, so there is no regional form to get wrong. The reading changes to xià in Mandarin, and Chinese carries an extra sense Japanese does not: 夏 also names the Xia, the earliest dynasty in Chinese tradition.
What happens in Japan during summer?
Summer is festival season. Neighbourhood 夏祭り fill July and August with food stalls, drums, and bon odori dancing, people wear 浴衣 (yukata), and riverside fireworks displays draw huge crowds. Obon, from 13 to 16 August in most of Japan, brings families home to tend graves and welcome ancestral spirits back.
