72 Seasons in Japan: A Poetic Year
The broad brush seasons of spring, summer, autumn (or fall) and winter give a pretty clear overview of the year in the world’s temperate regions, but why stop at just four?
Japan’s oldest calendar goes much further, splitting the year into 72 poetic snapshots, each describing the mood and feel of a few days via a single change in nature.
Using the ancient Chinese calendar as a framework, 17th-century astronomer, Shibukawa Shunkai, established the jōkyō-reki, rewriting Japan’s detailed diary of 24 sekki and renaming the 72 more finely divided kô, or micro-seasons. Beginning in February, in line with Lunar New Year, each sekki has three associated kô: a few words that evoke changes in climate, daylight, flora and fauna. Though something is undoubtedly lost in translation, each sekki still forms a rather beautiful haiku-esque poem.
Take a minute to pause and contemplate today’s micro-moment…

Spring - Haru 春

There’s something about the air in late spring that just makes you breathe deeper (unless you suffer from hay fever, perhaps!). There’s the sense that everything is growing again; a positive momentum after the winter haitus. And, of course, sunny days interspersed with plenty of April showers.
Spring in Japan usually means one thing: sakura, or cherry blossom. We highly recommend giving Japan’s main cherry-blossom weeks (March to early April) a complete miss, as overcrowding is a huge problem. However, if you’re canny and time your visit towards the end of April, perhaps from 15th onward (avoiding Golden Week at the April-May crossover, when the country grinds to something of a halt), and veer well away from the main blossom hot-spots, you can enjoy Japan’s spring landscapes with fewer crowds.

Summer - Natsu 夏

Sleepy bees bumble between flowers as the lazy, hazy days of summer lengthen. When the temperature rises, and it’s too hot to move quickly, shady spots and cool seas beckon. Ice creams are gobbled, grasses turn golden brown and barbeques sizzle.
Summers in Japan can get relentlessly hot, with temperatures rising during July, and frequently reaching over 40°C in August’s peak, so visits during this season should definitely be undertaken with caution. However, air conditioning is almost universal, and trips during the early summer months in May and June can be extremely rewarding if you plan them just right.

Autumn arrives softly, with russet tones and darker evenings, often as welcome relief from the intense summer heat. Window glass gets a sheen of condensation on cooler mornings, children wend their way back to school, and jumpers find their way back into the wardrobe.

Winter - Fuyu 冬

The start of December signals the proper start of winter for many and might, for some regions, bring the first few flurries of snow. Warm breath forms steam in the cold air, welcoming lights shine out through darkening evenings, and much of the natural world feels paused and still.
Japan is a lovely place to be in December, with Christmas in Japan having become a phenomenon in its own right! City streets twinkle with thousands of fairy lights, and the whole country gets fully festive in the run-up to the big day. During January and February, Japan’s winter landscapes are at their peak, seafood is in season, and the order of the day is wrapping up for warm walks or unwinding in steaming hot onsen.
