天気・季節Weather And Seasons

Japan is a country that lives by its seasons. The food you eat, the clothes you wear, the greetings you exchange, and even the stationery in shops all shift with the calendar. Seasonal awareness — 季節感 — is woven so deeply into the culture that ignoring it would mean missing a fundamental part of how Japanese people experience the world. For language learners, weather and season vocabulary is among the most immediately useful. It powers small talk, explains cultural customs, and shows up in everything from poetry to convenience store marketing.

Talking about the weather is the universal icebreaker in Japan, just as in English-speaking countries. A simple 今日はいい天気ですね ("Nice weather today, isn't it?") can open a conversation with anyone.

The Four Seasons#

Japan's temperate climate produces four distinct seasons, each celebrated with its own traditions, foods, and vocabulary.

Spring begins with the cherry blossom front moving north from Kyushu in late March, and people track its progress like a national event. Summer brings festivals, fireworks, and oppressive humidity. Autumn turns the mountains into a patchwork of red and gold, drawing visitors to temples framed by maple leaves. Winter covers the northern regions in deep snow while the rest of the country enjoys clear, crisp days.

Rain and the Rainy Season#

Rain plays a starring role in Japanese life, especially during 梅雨 — the rainy season that settles over most of the country from early June to mid-July. The name literally means "plum rain" because it coincides with the ripening of Japanese plums. Weeks of persistent drizzle and sticky humidity test everyone's patience, but the rain is essential for rice paddies and the lush greenery that defines the Japanese landscape.

During 梅雨, convenience stores fill their entrance displays with umbrellas, and you will see rows of clear vinyl umbrellas — the disposable kind that costs a few hundred yen — at every register. Children hang てるてる坊主, small handmade cloth dolls, outside their windows to wish for sunny skies.

Temperature and Conditions#

Japanese has specific adjectives for describing temperature that differ depending on whether you are talking about the weather, food, or objects. The air temperature adjectives pair naturally with the seasons.

The distinction between 暑い (hot weather) and 熱い (hot to the touch, like food or water) trips up many learners. Similarly, 寒い describes cold air temperature, while 冷たい is for cold objects or drinks. Getting these right sounds natural and shows real understanding.

Late summer and early autumn bring typhoon season. Japan is struck by several typhoons each year, and the vocabulary around them — warnings, cancellations, transportation disruptions — becomes suddenly practical.

Seasons in Culture#

Japanese culture marks seasonal transitions with specific words, foods, and customs. The concept of 旬 — seasonal peak — governs what appears on restaurant menus, at farmers' markets, and in supermarket displays. Eating strawberries in winter, bamboo shoots in spring, and persimmons in autumn is not just preference but cultural expectation.

Spring means 花見 — gathering under cherry trees with friends, food, and drinks. Autumn brings 紅葉 viewing trips to mountain temples. Summer explodes with 花火 festivals where millions line riverbanks to watch massive firework displays. Winter in Sapporo features the famous 雪祭り, with enormous snow and ice sculptures lit up against the night sky. Every season gives you a reason to travel and a reason to talk about the weather.
