Japanese Weather, Seasons, and Nature Vocabulary Reference

The four seasons (四季, shiki) hold a distinctive place in Japanese culture. From the waka poetry of the eighth century through contemporary packaging of seasonal snacks, Japanese arts, food, and conversation remain organized around the rhythm of spring, summer, autumn, and winter. The language has developed a rich vocabulary of weather, seasonal phenomena, and nature that is deeply interwoven with aesthetics and etiquette. Small talk in Japan almost always begins with a weather observation, and formal letters open with a seasonal greeting chosen from a calendar of fixed phrases.

This reference catalogs the vocabulary of weather, the seasonal cycle, characteristic natural phenomena (cherry blossoms, typhoons, autumn leaves, and snow), and the greetings used to acknowledge the season. It also introduces related nature vocabulary for landforms, plants, and animals that appears frequently in travel, literature, and everyday speech. Cultural notes explain why particular seasonal elements carry the weight they do in Japanese life.

Vocabulary is given in kanji and hiragana, followed by Hepburn romaji and English.


Basic Weather Vocabulary

Japanese Romaji English
天気 tenki weather
天気予報 tenki yohou weather forecast
晴れ hare clear / sunny
曇り kumori cloudy
ame rain
大雨 ooame heavy rain
小雨 kosame light rain
yuki snow
大雪 ooyuki heavy snow

The word 天気 literally means "heaven's spirit" or "heavenly conditions" and is one of the oldest inherited compounds in the language.


Describing the Weather

Adjectives for weather follow the i-adjective and na-adjective patterns covered elsewhere in this series.

Japanese Romaji English
暑い atsui hot (weather)
寒い samui cold (weather)
暖かい atatakai warm
涼しい suzushii cool / refreshing
蒸し暑い mushi atsui humid and hot
爽やか sawayaka refreshing (na-adj)
肌寒い hadazamui chilly
凍える kogoeru freezing (verb)
湿っぽい shimeppoi damp
乾燥している kansou shite iru dry

Grammar note: 暑い and 熱い are both read "atsui" but written with different kanji. 暑い is used only for weather or feeling hot in the sense of ambient temperature. 熱い is for hot objects such as water, tea, and fire. The same distinction applies to 寒い (cold weather) versus 冷たい (cold object, such as iced water).


The Four Seasons

Japanese Romaji English Approximate Months
haru spring March - May
natsu summer June - August
aki autumn September - November
fuyu winter December - February
四季 shiki the four seasons year-round concept

The Japanese school year begins in April, which places the start of the academic calendar squarely in spring and associates cherry blossoms with new beginnings.


Spring (春, Haru)

Japanese spring is dominated by one cultural event: cherry blossom viewing.

Japanese Romaji English
haru spring
sakura cherry blossom
花見 hanami flower viewing
桜前線 sakura zensen cherry blossom front
満開 mankai full bloom
花吹雪 hanafubuki flower blizzard (falling petals)
新学期 shin gakki new school term
入学式 nyuugakushiki entrance ceremony
入社式 nyuushashiki company entry ceremony
春一番 haru ichiban first strong south wind of spring

Cultural note: The 桜前線 is reported in daily news like a military front advancing northward from Kyushu to Hokkaido. Friends and coworkers coordinate 花見 parties based on the forecast. A sudden rain that knocks petals down before the gathering is called 花冷え (hana bie) or 花散らし (hana chirashi).

Related nature vocabulary for spring:

Japanese Romaji English
ume plum blossom
momo peach blossom
菜の花 nanohana rapeseed flower
チューリップ chuurippu tulip
たけのこ takenoko bamboo shoot
うぐいす uguisu bush warbler
つばめ tsubame swallow
蝶々 chouchou butterfly

Summer (夏, Natsu)

Japanese summer is hot, humid, and defined by festivals, fireworks, and the rainy season that opens it.

Japanese Romaji English
natsu summer
梅雨 tsuyu rainy season
蒸し暑い mushi atsui humid and hot
熱帯夜 nettaiya tropical night (over 25C overnight)
猛暑日 moushobi extremely hot day (over 35C)
夏祭り natsu matsuri summer festival
花火 hanabi fireworks
花火大会 hanabi taikai fireworks display
浴衣 yukata summer kimono
盆踊り bon odori Bon festival dance
お盆 obon Bon (ancestor festival)
夏休み natsu yasumi summer vacation
海水浴 kaisuiyoku ocean bathing
ka mosquito
semi cicada

Cultural note: The sound of cicadas, especially the abura zemi and tsukutsukuboushi, is one of the strongest summer markers in the Japanese soundscape. Children's summer vacation homework sometimes includes recording or identifying cicada species.


Autumn (秋, Aki)

Autumn is associated with foliage, harvest, and a brief, highly valued cool interval between summer heat and winter cold.

Japanese Romaji English
aki autumn
紅葉 kouyou / momiji autumn foliage / maple
紅葉狩り momijigari leaf viewing
月見 tsukimi moon viewing
十五夜 juugoya fifteenth night (harvest moon)
台風 taifuu typhoon
秋晴れ aki bare clear autumn sky
秋風 akikaze autumn wind
運動会 undoukai sports day (often held in autumn)
文化祭 bunkasai cultural festival
食欲の秋 shokuyoku no aki autumn of appetite
読書の秋 dokusho no aki autumn of reading
芸術の秋 geijutsu no aki autumn of the arts

The phrases 食欲の秋, 読書の秋, and 芸術の秋 are fixed idioms pairing autumn with appetite, reading, and the arts, respectively, expressing the idea that the cool weather invites introspective and cultural activities.

Typhoon vocabulary is important during late summer and autumn:

Japanese Romaji English
台風 taifuu typhoon
暴風 boufuu storm wind
避難 hinan evacuation
警報 keihou warning
注意報 chuuihou advisory

Winter (冬, Fuyu)

Japanese Romaji English
fuyu winter
yuki snow
雪景色 yuki geshiki snowy landscape
koori ice
shimo frost
つらら tsurara icicle
雪だるま yuki daruma snowman
スキー sukii skiing
スケート sukeeto skating
こたつ kotatsu heated low table
鍋料理 nabe ryouri hot pot cuisine
クリスマス kurisumasu Christmas
大晦日 oomisoka New Year's Eve
お正月 oshougatsu New Year
初日の出 hatsuhinode first sunrise of the year

The kotatsu, a low table with an electric heater underneath and a quilt draped over, is a winter cultural icon. Family life in many regions shifts toward gathering around the kotatsu for meals, TV, and naps during the coldest months.


Seasonal Greetings

Japanese letter writing opens with a seasonal greeting that sets the tone before addressing the recipient. A small selection:

Season Greeting Romaji Meaning
early spring 立春の候 risshun no kou in this season of the beginning of spring
late spring 春暖の候 shundan no kou in this season of spring warmth
early summer 初夏の候 shoka no kou in this early summer season
midsummer 盛夏の候 seika no kou in this peak summer season
early autumn 新秋の候 shinshuu no kou in this new autumn season
late autumn 晩秋の候 banshuu no kou in this late autumn season
early winter 初冬の候 shotou no kou in this early winter season
midwinter 厳冬の候 gentou no kou in this severe winter season

These phrases belong to the genre of formal business and personal letters and are rarely used in spoken conversation. Casual small-talk equivalents include:

  • 暑くなりましたね (atsuku narimashita ne) - it has become hot, has it not
  • 寒くなりましたね (samuku narimashita ne) - it has become cold, has it not
  • 過ごしやすいですね (sugoshi yasui desu ne) - it is pleasant weather

Language note: The sentence-final particle ね in weather talk is essential. It signals shared experience and invites agreement. Saying 暑いです alone without ね sounds like an objective statement; with ね it is a social opening.


Nature and Landscape

Japanese Romaji English
yama mountain
kawa river
umi sea
mizuumi lake
taki waterfall
mori forest
hayashi woods
tani valley
shima island
田んぼ tanbo rice field
hatake (non-rice) field
sora sky
kumo cloud
hoshi star
tsuki moon
太陽 taiyou sun

Japan's 富士山 (Fujisan, Mount Fuji) appears in seasonal compounds: 雪の富士 (yuki no fuji, snow-covered Fuji) in winter, 夏富士 (natsu fuji, summer Fuji) when the snow has melted.


Plants and Animals in Seasonal Poetry

The Japanese poetic tradition requires every haiku to include a 季語 (kigo, season word). A kigo immediately signals the season without stating it directly. Examples:

Kigo Japanese Season
cherry blossom spring
frog 蛙 (kaeru) spring
cicada summer
fireworks 花火 summer
moon autumn
persimmon 柿 (kaki) autumn
snow winter
tangerine 蜜柑 (mikan) winter

Poetic note: The most famous haiku in Japanese literature, Basho's 古池や蛙飛び込む水の音 (furuike ya kawazu tobikomu mizu no oto, "old pond, a frog jumps in, sound of water"), uses 蛙 (frog) as a spring kigo.


Common Mistakes

  • Mixing 暑い and 熱い. 暑い describes weather; 熱い describes objects.
  • Saying 寒い for cold objects. The correct word for a cold object, drink, or surface is 冷たい (tsumetai).
  • Using 春 as a simple calendar month. 春 refers to the cultural-climatic season, which runs roughly March to May; it is not interchangeable with 三月 (March).
  • Omitting ね in weather small talk. Weather comments without ね can sound flat or oddly declarative.
  • Using 梅雨 to mean "any long rain". 梅雨 specifically names the early-summer rainy season and is not used for autumn or winter rain periods.
  • Confusing 風 (wind, kaze) with 風邪 (cold illness, kaze). The two share the same sound in isolation but use different kanji and different sentence contexts.

Quick Reference

  • Weather: 天気 (tenki)
  • Forecast: 天気予報 (tenki yohou)
  • Sunny / cloudy / rainy: 晴れ / 曇り / 雨
  • Hot / cold: 暑い / 寒い

  • Rainy season: 梅雨 (tsuyu)
  • Typhoon: 台風 (taifuu)
  • Autumn foliage: 紅葉 (kouyou)
  • Snow: 雪 (yuki)

Frequently Asked Questions

What are the Japanese words for the four seasons?

The four seasons are 春 (haru) spring, 夏 (natsu) summer, 秋 (aki) autumn, and 冬 (fuyu) winter. The compound 四季 (shiki) means 'the four seasons' as a single concept and is central to Japanese aesthetics, poetry, and cuisine.

How do I say 'it is hot' or 'it is cold'?

暑い (atsui) is 'hot' for weather; 熱い (atsui) is 'hot' for objects or liquids. The kanji differs but the sound is identical. 寒い (samui) is 'cold' for weather and is written with a different kanji from 冷たい (tsumetai), which describes cold objects or liquids.

Why is cherry blossom season so culturally important?

桜 (sakura, cherry blossom) blooms for only about a week in each region and has become the defining symbol of Japanese spring and of impermanence. 花見 (hanami, flower viewing) gatherings under cherry trees have been practiced for over a thousand years. News programs broadcast daily 桜前線 (sakura zensen, cherry blossom front) updates tracking the bloom from south to north.

What is 梅雨 and when does it occur?

梅雨 (tsuyu) is the rainy season that occurs between roughly early June and mid-July in most of Japan. It is marked by prolonged light rain and high humidity. Business wardrobes shift for the duration, and mold prevention becomes a household concern. Hokkaido in the far north does not have a distinct 梅雨.

What is the difference between 雪 and 吹雪?

雪 (yuki) is snow in general. 吹雪 (fubuki) is a blizzard or driving snow. Other related words include 大雪 (ooyuki, heavy snow), 小雪 (koyuki, light snow), and 粉雪 (konayuki, powder snow). Japanese has developed a rich vocabulary for snow conditions because of the heavy snows of the Sea of Japan side of the country.

Are seasonal greetings used in business letters?

Yes. Japanese business correspondence opens with a seasonal greeting (時候の挨拶, jikou no aisatsu) that acknowledges the current season, such as 春暖の候 (shundan no kou, 'in this season of spring warmth'). These phrases are fixed and selected from a seasonal calendar rather than composed freshly each time.

How do I ask 'how is the weather'?

天気はどうですか (tenki wa dou desu ka) means 'how is the weather'. For a forecast: 天気予報は何ですか (tenki yohou wa nan desu ka). Small-talk weather phrases such as 今日は暑いですね (kyou wa atsui desu ne, 'hot today, is it not') are a standard conversation opener in Japan.
