May: The Month of Tending What We've Sown Cultivating Fortune in the Season of Fresh Greenery

Fresh leaves shimmer in the sunlight, and a soft breeze brushes gently against the cheek. The seeds planted in April are now sprouting into tender greens, reaching toward the sun. Across Japan, nature is at its most vibrantly alive. In the countryside, water flows into the rice paddies, young rice seedlings are carefully planted, and the mountains shift from pale green to deep verdant hues. According to the Jinguukan Kyusei Honreki and other traditional Japanese almanacs, May has long been honored as "the month of nurturing"—a time to tend patiently to what will eventually bear fruit. In this guide, we explore the rich wisdom embedded in May's calendar and traditions, and how this gentle yet powerful season invites us to cultivate our own good fortune.

Satsuki: The Poetry of May's Name

In the traditional Japanese calendar, May is called Satsuki (皐月). Several theories explain this beautiful name. The most widely accepted traces back to sanaezuki (早苗月)—"the month of planting young rice seedlings." Sanae refers to the tender rice shoots raised in seedbeds and then transplanted into the paddies. In the old lunar calendar, May was the sacred month when this transplanting took place. The Chinese character 皐 itself carries the meanings of "rice offered to the gods" and "a bright, open place beside the water"—a fitting choice for the month dedicated to the deity of the rice fields. In ancient Japanese, the sound "sa" was associated with the rice god and rice itself. We can hear it echoing in words still used today: samidare (五月雨, the early summer rains), saotome (早乙女, the young women who plant rice), and sawarabi (早蕨, young bracken shoots)—all woven into Japan's deep cultural relationship with rice cultivation. All these interpretations share a common thread: May is a month of nurturing, of entrusting something sacred to the earth. While April was the time to sow, May is the time to plant and tend. From the perspective of fortune cultivation, this is the ideal moment to care for what we've already begun, allowing it to take shape and grow.

The Solar Terms: Rikka and Shōman

Rikka (Beginning of Summer) Around May 5–20

"Summer rises" so reads the explanation in the Edo-period almanac Koyomi Benran. Rikka (立夏) is the seventh of the twenty-four solar terms and marks the calendar's beginning of summer, falling exactly halfway between the spring and summer solstices. In 2026, Rikka falls on Tuesday, May 5. From this day, the season takes one step further into summer. In the fields and forests, frogs begin their chorus (kawazu hajimete naku), earthworms emerge from the soil (mimizu izuru), and bamboo shoots stretch skyward (takenoko shōzu)—these are the three micro-seasons (shichijūnikō) that color Rikka's fifteen days. This is the time when the earth's energy rises most powerfully. It's a moment to align our own bodies and minds with nature's rhythm—to open ourselves outward. Open the windows. Let the breeze move through your home. Step into the sunlight. These simple acts are themselves powerful practices of fortune cultivation.

Shōman (Lesser Fullness) Around May 21 – June 4

"As all things grow abundant, the leaves and branches flourish." This is the spirit of Shōman (小満). In 2026, Shōman falls on Thursday, May 21. Its name—meaning "small fullness"—carries a quiet, modest depth. The seeds and seedlings planted through April and May are gradually, surely growing, and life begins to fill the heavens and earth. This is also when wheat begins to ripen, traditionally giving farmers a moment of quiet relief: "If it continues like this, we will harvest well." Shōman speaks beautifully to our own lives as well. It is the season when what we have been nurturing begins, ever so gently, to bear fruit. Even if things feel incomplete or still in progress, take a moment to notice what is steadily growing—and offer your gratitude. As we honor this small fullness, our fortune, too, quietly begins to swell.

Hachijūhachiya (八十八夜): The 88th Night — May 2

Just before Rikka arrives, we encounter one of Japan's uniquely native seasonal markers: hachijūhachiya (八十八夜), "the 88th night." Counted from Risshun (the beginning of spring), this day falls on Saturday, May 2 in 2026. Beloved through the folk song "Cha-tsumi" ("Tea Picking") "As summer draws near on the 88th night..." this date has long been a vital marker for Japanese farmers. As the saying goes, "the 88th night is the parting frost": after this day, the threat of late frost diminishes, and serious agricultural work can begin in earnest. There is also a poetic numerology at play: when the characters 八十八 (eighty-eight) are combined, they form the character 米 (rice)—an auspicious sign for those who tended the fields. But perhaps the most cherished tradition is this: drinking tea picked on the 88th night is said to bring a full year of good health and protection from illness. Tea leaves harvested at this time—called shincha (new tea) or ichibancha (first-flush tea) have spent the cold winter quietly storing nutrients, and emerge in spring with their first tender shoots. They are rich in theanine, the amino acid responsible for tea's gentle umami sweetness, and are widely considered the most flavorful tea of the year. This 88th night, we invite you to slow down, brew a cup of shincha, and offer a quiet wish for the year's wellbeing.

May 5: Tango no Sekku Honoring Life and Warding Off Misfortune

May 5 is Tango no Sekku, one of Japan's five seasonal festivals (gosekku). Also known as Shōbu no Sekku (the Iris Festival), it is celebrated today as Children's Day. "Tango" originally meant "the first horse day at the start of the month." It was not always tied specifically to May, but because the Japanese sounds for "horse" (go) and "five" (go) are identical, the festival eventually settled on the fifth day of the fifth month. The roots of Tango no Sekku reach back to ancient China, where May the start of the rainy season was called "the malevolent month" (akugetsu) due to the rise of illness and misfortune. The custom developed of warding off bad energy with strongly aromatic medicinal herbs such as iris (shōbu) and mugwort (yomogi). Texts from the Liang and Sui dynasties describe iris being chopped and steeped in wine to drink. When this practice arrived in Japan, it merged beautifully with an existing native tradition: satsuki imi (五月忌み), in which young women preparing for the rice planting cleansed themselves with iris before the sacred work began. The Chinese tradition of warding off illness and the Japanese tradition of pre-planting purification (misogi) intertwined and from this confluence emerged the Tango no Sekku we know today. From the Kamakura period onward, as samurai culture rose to prominence, the festival took on new meaning. The word shōbu (iris) sounds identical to shōbu meaning "to honor martial valor" and shōbu meaning "victory." Combined with the iris leaves' resemblance to a sword, the day became a celebration of boys' health and successful futures.

Shōbuyu (菖蒲湯) A Simple Fortune-Cultivating Ritual for May 5

The most accessible Tango no Sekku tradition is shōbuyu—bathing with iris leaves floating in the water. This is a beautiful and modern form of misogi, the ancient Japanese practice of purification through water. As we explored in our article on Misogi and the Bath, the fragrant power of iris leaves can help us release the spiritual fatigue that accumulates at the turning of seasons, and welcome the new season with a clear, refreshed spirit. The iris used for shōbuyu is the Acoraceae family iris not the purple-flowered hanashōbu. You can usually find it at flower shops or grocery stores around early May. Simply float a few leaves in your bath, and let the bright, herbal aroma rise around you. You'll feel both body and mind quietly settle into balance.

May 15: Aoi Matsuri (葵祭) A 1,500-Year-Old Prayer of Kyoto

Another grand event of May is Kyoto's Aoi Matsuri (the Hollyhock Festival), the annual celebration of Shimogamo Shrine and Kamigamo Shrine. Officially called Kamo Matsuri, it is one of Kyoto's three great festivals alongside Gion Matsuri and Jidai Matsuri, and a living tapestry of ancient courtly elegance. Its origins date back nearly 1,500 years, to the reign of Emperor Kinmei. When poor harvests and epidemics swept the country, divination revealed the displeasure of the Kamo deities. To restore harmony, ceremonial horse races and offerings were performed to pray for peace and good harvests. By the mid-Heian period, the festival had become so central to court life that whenever someone said "the festival," they meant the Aoi Matsuri. Even Murasaki Shikibu's Tale of Genji devotes vivid scenes to its splendor. In 2026, the Rotō no Gi, the festival's grand procession is scheduled for Friday, May 15. More than 500 participants in twelve-layered Heian robes, accompanied by 36 horses and four oxen, will process from the Kyoto Imperial Palace to Shimogamo Shrine and onward to Kamigamo Shrine. The Saiō-dai (the festival's princess figure), adorned with futaba aoi (wild ginger leaves), rides in a graceful palanquin at the procession's heart. The Aoi Matsuri endures because it has always been a prayer for the peace of the nation and the abundance of harvests. On this day, even from afar, we invite you to take a quiet moment to send your own prayer for the wellbeing of yourself and those you love, and for a year rich in meaningful harvests.

The Moon's Movements in May: Flower Moon and Blue Moon

May 2026 offers a particularly rich invitation to look up at the night sky because this month brings two full moons, one near its beginning and another at its very end. The first full moon arrives in the early hours of Saturday, May 2: the Flower Moon. Named by Indigenous peoples of North America for the season when wildflowers bloom in abundance, this moon resonates with the vibrant life force of fresh leaves and blossoms. Symbolizing abundance, love, and connection, the Flower Moon coincides with hachijūhachiya this year a doubly auspicious moment to receive the full energy of the natural world. Then, on Sunday, May 31, the second full moon rises: the Blue Moon. A second full moon within a single month is a rare occurrence, happening only once every few years—giving rise to the English expression "once in a blue moon." This particular Blue Moon is also a Micromoon, reaching its full phase at the year's farthest point from Earth. It carries a quieter, more inward energy, a perfect time for reflection and gentle release. Between these two full moons, the new moon arrives around Saturday, May 16—an ideal moment to set fresh intentions and quietly plant new seeds within.

Fortune-Cultivating Practices for May

1. Spend Time Among Fresh Greenery

As Rikka begins, the life force of plants reaches an extraordinary peak. Walk among new leaves. Take deep breaths beneath the cool shade of a park tree. Place a fresh houseplant near your window. Whatever form it takes, drawing close to the energy of fresh greenery replenishes our own ki (vital energy) with remarkable freshness. This is precisely why the Japanese practice of shinrin-yoku (forest bathing) is so deeply nourishing.

2. Take a Shōbuyu Bath: A Seasonal Misogi

On May 5, treat yourself to a shōbuyu bath. Simply float iris leaves on the surface of warm water and let the clean, herbal fragrance surround you. It washes away the fatigue of running from winter into spring and prepares your body and spirit for the warmth of summer ahead. There is no more accessible or more elegant fortune cultivation practice.

3. Savor New Tea The Blessing of the 88th Night

The shincha (new tea) released around May 2 carries the year's most vibrant energy. Brew it slowly in a teapot, watch the steam rise, and receive each sip with quiet gratitude. Sharing a cup of new tea with family or someone dear is a gentle yet powerful way to nurture the bonds between people, a beautiful kind of fortune cultivation in itself.

4. Tend to the Seeds You've Already Planted

Take a moment to ask yourself: what did I begin in April? How is it growing? Satsuki is the month of nurturing what has already been planted. Rather than starting many new things, this is the time to faithfully tend to what's already taken root. Even five mindful minutes a day, given to something you've begun, aligns you with the energy of the season.

5. Welcome Early Summer's Bounty to Your Table

May offers a generous overlap of spring's gentleness and early summer's vitality. Asparagus, new onions, broad beans, snow peas, green peas, new potatoes, the first bonito (hatsu-gatsuo), horse mackerel, whitebait, strawberries, loquats—all teeming with seasonal life force. Hatsu-gatsuo, in particular, is considered exceptionally auspicious: there's an old saying that eating the season's first food adds 75 days to one's life. Edo-era poets celebrated it in haiku" green leaves to the eye, the cuckoo on the hill, and the first bonito" and we can do the same, savoring early summer's blessings with appreciation.

6. Pause Beneath Two Full Moons

The Flower Moon on May 2 and the Blue Moon on May 31 invite us to look up and feel the moon's blessings. Moon-bathing—simply standing or sitting in moonlight is an ancient practice for quieting the heart and listening inward. Consider devoting the Flower Moon to themes of abundance, love, and connection, and the Blue Moon to deep reflection and gentle release. Each moon offers its own gift.

In Closing: May Your Fortune Grow Alongside the Fresh Greenery

Young rice seedlings settle into the paddies, fresh leaves bask in the sun, and every living thing reaches toward growth. As the beautiful name Satsuki suggests, this is the month dedicated to nurturing rice offered to the gods, a month for tending, with care and devotion, to whatever we are growing in our own lives. Fortune is much the same. It is not something we receive overnight, but something we plant, water, expose to sunlight, and patiently raise. Satsuki gently reminds us of our own quiet power to nurture. Bathe in the energy of fresh leaves. Cleanse yourself in the fragrance of iris. Offer gratitude over a cup of new tea. Send your wishes into the light of two full moons. These simple, intentional moments, woven through your days in May will surely tend your fortune well. May your fortune grow, gracefully and abundantly, alongside the fresh greenery of this beautiful season.

Iyasaka 弥栄!
