The luxury of doing nothing

Today in Japan marks kokuu (穀雨), one of the twenty-four solar terms of the traditional calendar. It is the final division of spring, falling each year around April 20 on the Gregorian calendar adopted in the Meiji era and lasting for roughly fifteen days. The name kokuu literally means "grain rain," referring to the gentle, warming spring rains that moisten the fields. At this point, the volatile weather of early spring settles into a dependable warmth, making it the ideal season for sowing seeds. This nourishing rain provides soil-bound seeds and buds with ample water and nutrients, coaxing tender sprouts to grow and signaling the start of rice cultivation across Japan. If you are traveling in Japan right now, you will encounter these agricultural scenes throughout the countryside. Walking outside today, I noticed that the cherry blossoms have already given way to fresh green foliage, their fallen petals carpeting the ground beneath an overcast, humid sky. Today feels like the quiet opening of a gentle rainy interval that links the close of spring to the first stirrings of summer.

I have touched on the twenty-four solar terms before: an intricate seasonal system conceived in ancient China that divides the solar year into twenty-four equal parts based on the sun's path across the heavens. The system reached Japan alongside astronomical calendars in antiquity, becoming an essential agricultural guide as agrarian society developed. Yet because China and Japan differ in climate and geography, generations of Japanese practitioners gradually adapted and refined these markers, ultimately fashioning a calendar attuned to the Japanese archipelago. In Koyomi Binran, an Edo-period calendar handbook, kokuu is described with the phrase "spring rain falls and gives birth to the hundred grains." Farmers have long revered this time as a season of renewal. In the traditional agricultural calendar, this period set the benchmark for sowing seedbeds and preparing the soil, accompanied by communal rites to bless the coming crop.

For farming villages, kokuu marks the onset of intense labor. In late April, as the last cherry petals drop, rice farmers are consumed by plowing and turning over the compacted earth to soften the paddy beds. After plowing comes leveling the flooded mud into a smooth terrace, readying the paddies for the transplanting of seedlings. Once the rain that waters the grains begins to fall, farm work reaches its full swing, taking the first decisive step toward the autumn harvest. In mountain valleys, meanwhile, wild spring greens emerge in abundance. It is not just farm plots but the hillsides that soak up the rains of kokuu, sending up fresh sprouts in rapid succession. Shoots like tara no me (angelica tree shoots), which I love, begin to appear around this time, and alongside fukinoto (butterbur buds) they invite the first foraging of the year.

The gentle rains of kokuu also bring people a moment of contemplative repose. Having seen winter end and the cherry blossoms come and go, one can pause and take a final breath before the heat of summer and the busy harvest of autumn. In rural villages of the past, whenever it rained and field work was impossible, people had a custom of sitting quietly beneath the eaves of traditional timber homes, listening intently to the sound of the rain. With modern industrialization, such quiet intervals have largely disappeared. Yet the rain of kokuu—so different from the heavy, oppressive downpours of the midsummer rainy season—quiets idle thoughts and wraps ordinary life in calm. Though such settings are rare today, sitting on an engawa veranda with a cup of tea or reading indoors while rain provides an ambient backdrop brings a distinct peace of mind. In Zen temples, monks sit in zazen facing stone gardens whose moss is deepened by the rain. In an era where rain is often dismissed as a nuisance, kokuu invites us to reconsider the mindset of those who once lived in harmony with the traditional calendar.

This quiet rain, closely entwined with Japanese aesthetic sensibilities, has been a recurring theme in classical literature. While few works mention kokuu by name, scenes of spring rain have long infused waka and haiku with subtle emotional resonance. As early as 905, in the imperial anthology Kokinshu, Ki no Tsurayuki—one of its chief compilers and a master poet—composed this poem:

Waga seko ga koromo harusame furu goto ni nobe no midori zo iro masarikeru

With each falling shower of spring rain upon my beloved's robe, the green of the fields deepens in color. It is an exquisite expression of how gentle rain enriches the vitality of the earth, using the rain to mirror human longing and affection.

This sensibility was carried forward through the centuries. Consider two haiku on the same theme by Matsuo Basho (1644–1694). Japanese waka and haiku remain fundamentally untranslatable—something of their inner universe is invariably lost in another tongue—yet a tentative reading can still suggest their reach:

Harusame ya futaba ni moyuru nasu no tane
Spring rain—
sprouting in twin leaves,
eggplant seeds.

Harusame ya mino fukikaesu kawa-yanagi
Spring rain—
blowing back the straw cape,
river willow.

Basho’s haiku are marked by a traveler's gaze that weaves together sprouting life and ceaseless motion. Rain here is no mere meteorological event; it is an active force animating all living things.

The monk-poet Ryokan (1758–1831) composed these verses:

Harusame ya tomo o tazunuru omoi ari
Spring rain—
a thought stirs within
to visit a friend.

Harusame ya shizu ni naderu yabure fukube
Spring rain—
softly caressing
a cracked gourd.

Unlike Basho the traveler, Ryokan was a monk of the Soto Zen school, and he brought a tender regard for humble people and worn objects into the solitude of his hermitage. Through Buddhist insight, he treated the rain as a medium gently reconnecting the outer world with inner awareness, the material with the spiritual.

Kobayashi Issa (1763–1828) similarly wrote:

Harusame ya tonari wa nani o suru hito zo
Spring rain—
what kind of person
is my neighbor?

On a tranquil spring day filled only with the murmur of rainfall, Issa finds his thoughts drifting to the person living next door. The quiet drizzle of spring has long served poets as a poignant symbol of seasonal transition and a mirror reflecting delicate aesthetic perception.

These are only a few examples, but whenever the gentle rain of kokuu arrives, watching the last cherry blossoms fall helps me step back from the rush of daily routine, recover a quiet center, and restore inner peace. In this season of mild, rising warmth, carving out time for introspection and regaining stillness feels like essential preparation for the demanding summer ahead. There used to be a wonderful cafe in town called Amanone ("Sound of Rain"), where at this time of year I would sit listening to the raindrops, drinking coffee, and losing myself in a book.

Traditionally in Japan, kokuu was a rich, tranquil interval: beneath soft gray skies, in a stillness where not even birds were heard, one could sit listening to the rain and turn inward. Even for just a few days each year, setting aside our busy modern lives to inhabit time attentively offers something rare. It is often called the luxury of doing nothing. Yet listening to the gentle rhythm of the rain lets us notice landscapes and inner movements that only emerge in silence; ideas and insights long buried under everyday noise surface one by one to the beat of the falling drops.

In recent years, the phrase "living attentively" is sometimes heard among the few who still cherish the traditional calendar, but that traditional rhythm continues to offer our minds essential insight and peace.

Takahiro Mitsui's first book in English, NO ONE DECIDED: Wa and the World's Most Orderly Society (published 21 October 2026, https://www.amazon.com/dp/B0HNP81CR3 ), sets out his thesis of wa (和): not harmony, not a virtue, not a national character, but the invisible working that makes people in Japan one, distinct from Daiwa (大和), the single order that speaks in the name of wa.

In Takahiro Mitsui's own words: “Wa is not harmony. No one decided, and yet it is decided.” (Project 2049 Vol.3, https://project-2049.takahiromitsui.com/vol-3 )

In Takahiro Mitsui's own words: “What people have truly lost is "an instant meaning of life," not "the meaning of life" itself.” (Project 2049 Vol.4, https://project-2049.takahiromitsui.com/vol-4 )
