October, Kannazuki: In the Clear Light, Taking Stock of What Has Ripened

October, Kannazuki: In the Clear Light, Taking Stock of What Has Ripened

October 2026

This year, October 23 is a rather special day.

It is Sōkō (霜降), Frost's Descent, one of the twenty-four solar terms: the season when dew begins to turn to frost, and the last solar term of autumn. And the night of that same day is the thirteenth day of the ninth month in the old lunisolar calendar. It is Jūsanya (十三夜), the thirteenth night, the other great night of autumn moon viewing.

Sōkō and Jūsanya last fell on the same day in 1988, thirty-eight years ago. The next time they meet will be in 2064.

As autumn deepens and the air grows ever clearer, two calendars quietly lay one hand upon the other. October is a month that holds this kind of meeting within it.

When the air is clear, distant things come into view. The outline of the moon, the ridgeline of the mountains, and also the things you yourself have spent a year bringing to fruition. In this guide, we follow the calendar of October 2026 through three movements, early, middle, and late, and consider how to receive this month and how to move through it.

On the Name Kannazuki

In the traditional Japanese calendar, October is called Kannazuki (神無月).

The best-known explanation is that the gods of every region gather in Izumo during this month, leaving their home provinces empty, and so it came to be called kaminashizuki, the month without gods. For the same reason, the Izumo region has long called this month Kamiarizuki (神在月), the month when the gods are present.

From the standpoint of how the word was formed, however, the more widely supported view holds that the character 無 (na) here stands for the particle meaning "of," so that the name originally meant "the month of the gods." Not a month in which the gods disappear, but a month in which the gods are honored. Both explanations reveal how deeply this season was bound up with harvest and gratitude.

Kannazuki was, in fact, originally the name of the tenth month of the old lunisolar calendar. In 2026, that tenth lunar month begins on November 9 of the modern calendar.

Early October: October 1 to October 10, a Light of Beginnings

October 1: Tensha-nichi and Ichiryū Manbai-bi on the Same Day

October opens with Tensha-nichi (天赦日), regarded as the highest-ranking auspicious day in the traditional calendar.

Tensha-nichi is said to be the day on which heaven forgives all wrongs, and it comes around only a handful of times each year. The autumn Tensha-nichi is fixed as the day of tsuchinoe-saru (戊申) in the sexagenary cycle, and this year that day falls on October 1.

On top of this, the day also coincides with Ichiryū Manbai-bi (一粒万倍日), the day when a single grain of rice is said to return ten thousandfold. It is a combination long considered favorable for beginning something new, for taking a first step.

We would like to say plainly that the rokuyō (六曜) designation for this day is Butsumetsu (仏滅), traditionally an inauspicious day. Tensha-nichi, however, has long been regarded as so great a day that it outweighs other unfavorable designations. At KICHIYA, we would like to receive this day as one for beginning small, but surely.

October 1 is also, in Japan, the long-established day of koromogae (衣替え), the seasonal change of clothing. It has its origins in kōi (更衣), a ceremony of the Heian-period imperial court, and from the Meiji era onward, June 1 and October 1 became fixed as the days for changing between summer and winter dress. To renew what we wear is to renew how we feel. On the morning of Tensha-nichi, exchanging the contents of your closet for autumn and winter clothing is a beginning very much in keeping with the day.

October 1 to 7: The Lingering Echo of the Overlapping Month

In Kyūsei Kigaku (九星気学), nine-star astrology, the months change in step with the setsu, the solar terms that open each month. So from October 1 until October 7, the day before Kanro, we are still within September's month board: the continuation of the "overlapping month," in which Ippaku Suisei (一白水星), the First White Water Star, sits at the center of both the year and the month.

The flow we described in September, "things come into order by not moving," continues for just a little longer. Begin small, and set things in order with care. Early October is a time to cherish that balance.

Mid-October: October 8 to October 19, Offering the First Harvest

October 8: Kanro (寒露), Cold Dew

At 3:29 p.m. on October 8, Japan Standard Time, the sun reaches a celestial longitude of 195 degrees, and we enter Kanro, one of the twenty-four solar terms. In Pacific Daylight Time that is 11:29 p.m. on October 7.

The Edo-period almanac Koyomi Benran (こよみ便覧) described Kanro in these words:

陰寒の気に合って、露結び凝らんとすれば也 Inkan no ki ni ōte, tsuyu musubi koran to sureba nari Meeting the cold air, the dew gathers and is on the verge of freezing.

It is the season when the dew, touched by chill air, seems about to turn to ice.

During Kanro, the seventy-two microseasons (七十二候) move as follows.

Kōgan kitaru (鴻雁来), around October 8 The wild geese arrive from the north.

Kiku no hana hiraku (菊花開), around October 13 The chrysanthemums begin to bloom.

Kirigirisu to ni ari (蟋蟀在戸), around October 18 Autumn insects sing at the door. The kirigirisu named here is thought to be what we now call the cricket.

From October 8: The Month Star Becomes Kyūshi Kasei

With Kanro, the month board of nine-star astrology also changes. October 2026 (October 8 to November 6) is the month of tsuchinoe-inu (戊戌), and the star entering the central palace is Kyūshi Kasei (九紫火星), the Ninth Purple Fire Star.

If Ippaku Suisei is water, Kyūshi Kasei is fire. It is the last of the nine stars, the ninth, and is said to symbolize the light of the sun, brightness, intellect, and beauty. Just as fire illuminates the darkness, it is a star whose nature is to bring hidden things into the open, and to let matters be seen clearly.

Within a year of Ippaku Suisei, a month of Kyūshi Kasei comes around. Picture light falling across the surface of water that has been allowed to settle and grow clear. The more you set your inner self in order in September, the more sharply October may show you what truly matters to you.

Yet the light of fire can also illuminate things we would rather not see. Rather than hurrying to pass judgment on what comes into view, first receive it quietly. That, we believe, is the best way to keep company with a month of Kyūshi Kasei.

October 11: New Moon, the Beginning of the Ninth Lunar Month

The new moon arrives at 12:50 a.m. on October 11, Japan Standard Time. In Pacific Daylight Time that is 8:50 a.m. on October 10. This day of the new moon becomes the first day of the ninth month in the old lunisolar calendar, and counting from here, the thirteenth day will be Jūsanya.

October 15 to 17: Kannamesai (神嘗祭)

Each year from October 15 to 17, Ise Jingū holds Kannamesai. It is the festival at which the first grain harvested that year is offered, before anything else, to Amaterasu Ōmikami (天照大御神), in gratitude for the harvest.

Some 1,500 rites are held at Ise Jingū over the course of a year, and among them Kannamesai is regarded as the most important. Together with rice grown by His Majesty the Emperor at the Imperial Palace, rice stalks offered by farmers from across the country are hung on the inner fence of the sanctuaries as kakechikara (懸税). It is a scene in which the capital and the provinces alike offer their harvest under a single gratitude.

Niinamesai (新嘗祭), held on November 23, takes place after Kannamesai. First the earliest fruits are offered, and only then do people partake of them themselves. In this order, we can see the shape that gratitude takes in Japanese life.

To translate this into our own lives, these three days are a time to turn our attention to our "first harvest." What first took shape for you this year? What was the first result you held in your hands? Take a moment to remember whose help made it possible.

October 17: Kinoe-ne (甲子), the First Day of the Sixty-Day Cycle

October 17, the final day of Kannamesai, is the day of kinoe-ne, the first of the sixty combinations in the sexagenary cycle. Coming around once every sixty days as the beginning of a new cycle, it has long been considered a good day for starting things.

Just after giving thanks for the first harvest, a new cycle begins. As a sequence in the calendar, it is a truly beautiful flow.

Late October: October 20 to October 31, on the Nights When Frost Falls

October 20: The Autumn Doyō Begins

At 6:13 p.m. on October 20, Japan Standard Time, we enter the autumn Doyō (土用). In Pacific Daylight Time that is 2:13 a.m. on October 20. Doyō continues until November 6, the day before Rittō, the beginning of winter.

Doyō is a period of transition lying between one season and the next. In the philosophy of the five elements, it is said to be the time when the energy of earth circulates, and since long ago there has been a custom of refraining from disturbing the soil, such as gardening or laying foundations. Days called mabi (間日), however, have traditionally been regarded as exceptions. During the autumn Doyō, the mabi are the days of the sheep, the rooster, and the boar. In October this year, these fall on the 24th, 26th, and 28th.

The turning of the seasons is a time when both body and mind are easily unsettled. Rather than making large moves, set your footing in order for the winter ahead. This may also be a good period for slowly digesting what the light of Kyūshi Kasei has brought into view.

October 20: Ebisu-kō (えびす講)

October 20 is also the day of Ebisu-kō.

Ebisu, one of the Seven Gods of Good Fortune, is said to be a rusugami (留守神), a god who stays behind. Rather than traveling to Izumo in Kannazuki, he remains in each place, watching over the people. Ebisu-kō is the observance in which Ebisu is honored, thanks are given for a year passed safely, and wishes are made for thriving business, abundant harvests, and plentiful catches.

The Ebisu-kō of October 20 has been especially cherished in eastern Japan. There is a custom of making offerings at home of kenchin-jiru vegetable soup, ankoro-mochi rice cakes, fish, and other foods, and in Nihonbashi, Tokyo, the Bettara-ichi market is held on the 19th and 20th. In the Kansai region, the best known is Tōka Ebisu (十日戎) on January 10, but some places, such as Ebisu Shrine in Kyoto, hold Hatsuka Ebisu, the twentieth-day Ebisu, on October 20. In haiku, "Ebisu-kō" is also a seasonal word for early winter.

Even while the gods are away, there is a presence watching over our homes and our daily lives. Seen this way, Ebisu-kō might also be called a day of gratitude for the things closest to us.

October 22: Tsuchinoto-mi (己巳)

Among the days of the serpent, the day of tsuchinoto-mi, which comes around once every sixty days, has been especially treasured as a day associated with Benzaiten (弁財天). It is considered a day connected with financial fortune and the arts.

October 23: Sōkō and Jūsanya, Together for the First Time in Thirty-Eight Years

At 6:38 p.m. on October 23, Japan Standard Time, we enter Sōkō, one of the twenty-four solar terms. In Pacific Daylight Time that is 2:38 a.m. on October 23.

Koyomi Benran described Sōkō in these words:

露が陰気に結ばれて霜となりて降るゆへ也 Tsuyu ga inki ni musubarete shimo to narite furu yue nari Bound by the cold air, the dew becomes frost and falls.

It is the season when, in the chill of morning and evening, dew changes its form into frost. The seventy-two microseasons move as follows.

Shimo hajimete furu (霜始降), around October 23 The first frost falls.

Kosame tokidoki furu (霎時施), around October 28 Light rain falls now and then.

Momiji tsuta kibamu (楓蔦黄), around November 2 Maple leaves and ivy turn color.

And this night is Jūsanya.

Jūsanya is the moon of the thirteenth day of the ninth lunar month, and is also called Nochi no Tsuki (後の月), the later moon. Whereas moon viewing on Jūgoya, the fifteenth night, came to Japan from China, Jūsanya is considered a custom born in Japan. It is said to have begun in the year 919, when the Cloistered Emperor Uda praised the moon of this night as musō (無双), a beauty without equal.

Because taro is offered on Jūgoya, that moon is called Imo Meigetsu, the taro moon. Jūsanya, by contrast, is also called Kuri Meigetsu, the chestnut moon, or Mame Meigetsu, the bean moon, because chestnuts and beans are offered. In many regions, thirteen dumplings are set out, in keeping with the thirteenth night. There is also a traditional saying that viewing only one of the two moons, Jūgoya or Jūsanya, is katamizuki (片見月), a one-sided moon viewing, and brings poor luck. If you saw the moon of Jūgoya on September 25, please do look up at the moon on this night as well.

The moon of Jūsanya is still a few days short of full. If the moon of Jūgoya in September was a moon "just before fullness," then the moon of Jūsanya lies even further before it. And people of the past chose this very moon, deliberately, to cherish.

To gaze at a moon not yet full, on the night when dew becomes frost. On this night, when the entrance to winter comes into view on the calendar, it is fitting to count this year's harvest and quietly picture what you wish to nurture from here on.

October 26: Full Moon

The full moon arrives at 1:12 p.m. on October 26, Japan Standard Time. In Pacific Daylight Time that is 9:12 p.m. on October 25.

In the English-speaking world, the full moon that follows the Harvest Moon is traditionally called the Hunter's Moon. The name recalls the season when, with the fields already reaped, people hunted to prepare for winter. Just as chestnuts and beans were offered to the moon of Jūsanya in Japan, here too the moon is bound up with the ways people readied themselves for winter.

October in Numbers

The number 10 is the number at which, having gone once around from 1 to 9, we move up a place value for the first time. Besides the number ten, the kanji 十 carries the meanings "the whole, completeness, all things" (according to the character dictionary Jitsū, 字通), and that meaning lives on in words such as jūbun (十分), enough, and jūzen (十全), perfect and complete.

Kyūshi Kasei, the last of the nine stars, enters the center, and we arrive at the month of "ten." One cycle comes to fullness and rises to the next place. October might be called the month for confirming that this year's harvest has been jūbun, truly enough.

Auspicious Days in October 2026

Tensha-nichi, the day heaven forgives October 1 (Thu)

Ichiryū Manbai-bi, when one grain multiplies ten thousandfold October 1 (Thu), 11 (Sun), 14 (Wed), 23 (Fri), 26 (Mon)

October 1, which coincides with Tensha-nichi, is the most auspicious day of the month. October 23 falls on Sōkō and Jūsanya, and October 26 on the full moon.

Taian, the most favorable day of the six-day cycle October 2, 8, 13, 19, 25, 31

Tora no Hi, days of the tiger October 7, 19, 31

Days when what goes out is said to return. October 31 also falls on Taian.

Mi no Hi, days of the serpent October 10, 22 (tsuchinoto-mi)

Kinoe-ne, the first day of the sixty-day cycle October 17

Something we would rather say plainly

October 11 is an Ichiryū Manbai-bi, but it also coincides with Fujōju-bi (不成就日), a day on which matters are said not to come to fruition. October 19, too, brings together Taian and a day of the tiger, while also falling on Fujōju-bi. On days where the auspicious and the inauspicious sit side by side, we recommend using the time for preparation and review rather than for bold declarations.

The Movement of the Stars in October

Please note: the following draws on Western astrology, which is not scientifically established. We offer it as one way among many of receiving the season.

From October 3: Venus Retrograde

Venus turns retrograde in Scorpio on October 3 and returns to direct motion in Libra on November 14 (November 13 in North America). Venus is said to govern love, relationships, beauty, and the values we attach to money. A retrograde period is thought of as a time for reassessing the worth of what we already have, rather than acquiring something new. This also overlaps with the "coming into view" of Kyūshi Kasei's month.

October 11: New Moon in Libra (12:50 a.m. Japan Standard Time)

A new moon in the sign of harmony and relationships.

October 23: The Sun Enters Scorpio (Sōkō)

At the very moment of Sōkō, the sun enters Scorpio. Scorpio is associated with depth, focus, and the power to see into the essence of things.

From October 24: Mercury Retrograde

Mercury turns retrograde in Scorpio on October 24 and returns to direct motion on November 14 (November 13 in North America). It is said to be a period when misunderstandings around words, contracts, communication, and travel arise more easily. It is considered wise to settle important contracts and commitments by mid-October if you can, or otherwise to confirm them with more care than usual.

October 26: Full Moon in Taurus (1:12 p.m. Japan Standard Time)

A full moon in Taurus, the sign said to govern the five senses, abundance, and the harvest.

In Closing

October is a month in which, through clear air, light illuminates all things.

To begin small on the morning of Tensha-nichi. To give thanks for the first harvest around the time of Kannamesai. To remember our gratitude for the things closest to us on Ebisu-kō. And on the night of Sōkō, looking up at the moon of Jūsanya, to take stock of what has ripened this year.

The light of Kyūshi Kasei sometimes illuminates things we would rather not see. And yet, to see clearly is also to be able to choose what to nurture next.

On the night of October 23, when Sōkō and Jūsanya meet for the first time in thirty-eight years, please do make a little time to look up at the moon.

Luck is something you cultivate. We wish you an October rich in harvest.
