The Season Explained

This kō completes a pairing already planted six months and thirty-six kō earlier, at #64 (乃東生, "self-heal sprouts," the first kō of 冬至, the winter solstice): the same plant, doing the reverse of almost everything else growing around it. It sprouted at the year's darkest point and withers now, at its brightest — a small, deliberately contrary rhythm the old calendar noticed and built two exactly opposite kō around.

The plant itself carries two names depending on which trait mattered to whoever was naming it. 靫草 (utsubogusa) describes its shape — the flower spike resembles an utsubo, the quiver worn at the hip for carrying arrows. 夏枯草 (kakosō), "summer-withering grass," describes exactly what this kō is watching happen. Its English name, self-heal (sometimes "all-heal"), points to a third identity entirely: a herbal medicine, brewed for its diuretic and anti-inflammatory properties and used topically on swelling and sprains, valued in both East Asian and European traditional medicine independently.

Foods of the Season
魚 · Fish
太刀魚TachiuoCutlassfish

A long, silver, blade-shaped fish moving into season now — mild and rich enough that a simple salt grill is often the best way to serve it.

果 · Fruit
桃MomoPeach

The fruit itself, distinct from the blossom already noted much earlier in the calendar — soft, fragrant, and best eaten within a day or two of full ripeness.

菜 · Vegetables
茄子NasuEggplant

Coming into full season, at its most tender before the summer heat toughens the skin.

紫蘇ShisoPerilla

The green leaf variety is at its most fragrant right now, classically paired with sashimi or rolled into tempura.

Blooms in Season
靫草Self-heal
藪萱草Orange daylily

Utsubogusa's own purple spikes are already fading as this kō opens — worth looking for now specifically because it's disappearing, in contrast to yabukanzō, whose bright orange, single-day blooms are just reaching their peak nearby.

Custom & Saying

夏至祭Geshi-sai

At Futami Okitama Shrine on the Ise coast, the sacred Meoto Iwa ("wedded rocks") — a large and small rock joined by a thick shimenawa rope — frame the sunrise from May through July. Only around the summer solstice does the sun rise from the exact center point between them, and worshippers gather before dawn on the solstice itself to watch it happen while performing purification in the sea below, timing a ritual precisely to an astronomical event the rocks happen to align with only a few mornings a year.

Name & Etymology

乃東, the kō's own name for the plant, is an old, largely obsolete term rarely used outside this exact calendar entry — most contemporary sources reach for utsubogusa or kakosō instead, meaning the seventy-two kō may be one of the last places this particular word for the plant still gets any regular use at all.

行
Gyō
Things to Do
Look for utsubogusa's purple spikes before they're gone

This kō marks the plant already withering — worth finding a still-blooming patch in the next few days rather than assuming it'll still be there next week.

If near Ise around the solstice, check the sunrise timing at Futami

The alignment between the wedded rocks and the rising sun is tightest for only a few mornings each year, centered on the solstice itself.

備

Preparing
Eggplant and shiso both wilt fast in summer heat once picked

Buy close to when you'll actually cook them rather than letting either sit — both lose their best texture within a day or two off the plant.

If you dry your own herbs, self-heal's flower spike is traditionally harvested right as it browns

The withering this kō describes is, for herbalists, the actual harvest signal rather than something to wait out.

想

A Reflection

The same plant that pushed up through frozen ground at the year's darkest point is quietly giving out now, at its brightest — not because anything is wrong with it, but because its own particular rhythm was never actually about the light everyone else was following. What in your own life runs on a schedule that looks backwards from everyone around you, thriving when things are hardest and fading exactly when things finally ease up?
