What Is Ohigan? Japan's Autumn Equinox Ancestor Tradition

What Does "Ohigan" Mean?

Higan comes from the Sanskrit word paramita, meaning "the other shore," and it refers to the far bank of enlightenment in Buddhist teaching, as opposed to shigan, "this shore," the world of everyday suffering and attachment. Ohigan takes place twice a year, once around the spring equinox and once around the autumn equinox, each time lasting seven days: the equinox itself sits at the center, with three days on either side. The autumn instance is what most people mean when they talk about Ohigan in the context of ancestor remembrance, since it falls alongside Japan's official Autumnal Equinox Day (Shubun no Hi), a national holiday legally defined as a day to "respect ancestors and mourn the dead."

The History and Origins of Ohigan

Ohigan's roots are older than its Buddhist name suggests. Long before Buddhism arrived in Japan, farmers already treated the equinoxes as significant turning points, visiting ancestral graves in spring before planting and again in autumn before harvest, asking for the spirits' favor. When Buddhism took hold, this agrarian ancestor worship fused with the concept of the six paramitas, the perfections a practitioner cultivates on the path to the other shore, giving the custom its name and its philosophical framing.

The first recorded court ceremony tied to the equinox dates to the Heian period (794 to 1185 CE), when the imperial court held services referred to as Shuki Koreisai in autumn and Shunki Koreisai in spring, blending Shinto reverence for ancestral spirits with Buddhist ritual. The practice spread beyond the aristocracy during the Muromachi period as Buddhist temples popularized it among ordinary worshippers, and by the Edo period, visiting family graves during the equinox week had become a genuine folk custom nationwide, no longer confined to formal religious observance. In 1878, the Meiji government formalized the autumn ceremony as Shuki Koreisai, an occasion to honor past emperors alongside deceased family members. After the Second World War, Japan's postwar constitution required a clearer separation of religion and state, so in 1948 the holiday was renamed Shubun no Hi, Autumnal Equinox Day, and stripped of its explicit imperial framing even as the underlying custom of visiting graves continued almost unchanged.

Why the Equinox? Buddhist Symbolism and the Six Paramitas

The choice of the equinox is not incidental. On these two days of the year, the sun rises due east and sets due west, and in traditional Buddhist cosmology, the Western Pure Land, the realm reached upon enlightenment, sits directly along that path. With day and night in near-perfect balance, the equinox was long understood as the moment when the distance between this world and the other shore is at its shortest, making it the most auspicious time to reach out to those who have already crossed over.

Traditionally, each of the seven days of Ohigan corresponds to one of the six paramitas: generosity, moral discipline, patience, diligent effort, meditative concentration, and wisdom, with the equinox day itself set aside for reflecting on all six together. Few people today observe this practice formally day by day, but the underlying idea, that the period is meant for both remembrance and quiet self-examination, still informs how many families describe what the week is for.

How Ohigan Is Observed

Ohaka Mairi (Grave Visiting)

The central ritual of Ohigan is ohaka mairi, visiting the family grave. Families sweep away fallen leaves, pull weeds, and wash the headstone with water before setting out fresh flowers, usually chrysanthemums for the season, along with incense, and small offerings of rice, water, or sake. Multiple generations often make the trip together, sometimes traveling back to rural hometowns for the occasion, turning the visit into both a religious act and a family reunion.

Ohagi and Botamochi (Ritual Sweets)

No Ohigan observance is complete without ohagi, a soft ball of glutinous rice coated in sweetened azuki bean paste. The same sweet is called botamochi vs ohagi in spring, named for the botan (peony) blooming at that time of year, while the autumn version takes its name from hagi, the bush clover that flowers in September. Some recipes finish the rice ball in a coating of kinako (roasted soybean flour) instead of, or alongside, the classic anko exterior. The sweet is placed on the family altar or grave as an offering as much as it is eaten, since the deep red of the azuki paste has long been believed to ward off evil spirits, and the glutinous rice itself is a quiet nod of gratitude for the year's harvest.

Ohigan Around Japan Today

Ohigan has stayed remarkably durable even as religious affiliation in Japan has declined. Surveys consistently show that most Japanese people do not identify strongly with any organized religion, yet the majority still observe Ohigan with a grave visit, a phenomenon scholars describe less as devout worship and more as an ordinary, almost automatic part of family life. Regional flavor varies. In parts of the Tohoku region, Ohigan overlaps with community harvest gatherings built around imoni, a shared taro stew, folding ancestor remembrance into a larger celebration of the season. The tradition has also traveled with the Japanese diaspora. Buddhist temples in Hawaii and California hold their own spring and autumn Ohigan services, adapting the ritual for communities far from the family graves it was originally built around.

Around the same week, higanbana, the red spider lily, (Lycoris radiata) bursts into bloom almost on cue, its bright red flowers appearing along rice paddies, riverbanks, and cemetery paths. The flower's Japanese name literally means "higan flower," and its toxic bulbs were traditionally planted at the edges of farmland and graves to keep rodents away, giving the plant a slightly eerie reputation alongside its striking beauty. For many visitors, spotting a field of higanbana in full bloom is the clearest visual signal that Ohigan season has arrived.

How to Honor the Spirit of Ohigan at Home

You do not need a family grave in Japan, or even a Buddhist background, to take something from Ohigan. At its core, the custom is an invitation to pause during a seasonal turning point and think about the people who came before you. A small, quiet gesture, lighting a candle, setting out a photo, or simply taking a moment to remember someone, captures the spirit of the week without requiring the full ritual.

Food is an easy entry point too. Bokksu's Kinako Azuki Crunch, made with roasted soybean powder and freeze-dried azuki beans, draws on the exact same flavor pairing found in traditional kinako-dusted ohagi, giving you a genuine taste of the season's signature sweet without needing to prepare rice and red bean paste from scratch.

Frequently Asked Questions

What is the difference between Ohigan and Obon?

Ohigan is tied to the spring and autumn equinoxes and centers on visiting family graves and reflecting on Buddhist teaching, while Obon is a separate mid-August festival built around the belief that ancestral spirits temporarily return to the household. The two observances share a focus on ancestors but rest on different beliefs and take place at different times of year.

What is the difference between ohagi and botamochi?

Ohagi and botamochi are essentially the same sweet, glutinous rice coated in sweet azuki paste, with the name changing by season. Botamochi is served in spring, named after the peony, while ohagi is served in autumn, named after the bush clover.

Why do Japanese people visit graves during Ohigan?

The equinox was traditionally believed to be the moment when the distance between this world and the afterlife is shortest, making it the most fitting time to honor ancestors. Grave visiting during Ohigan blends this Buddhist belief with older Japanese ancestor worship that predates Buddhism's arrival in the country.

What are the six paramitas?

The six paramitas are the six perfections in Buddhist practice: generosity, moral discipline, patience, effort, meditation, and wisdom. Traditionally, each of the seven days of Ohigan was set aside to reflect on one of these virtues.

Is Ohigan a public holiday?

The autumn equinox itself, known as Shubun no Hi or Autumnal Equinox Day, is a national holiday in Japan, though the surrounding six days of the Ohigan week are not official days off. The spring equinox holiday, Shunbun no Hi, works the same way.

What flower is associated with Ohigan?

Higanbana, the red spider lily, blooms almost exactly around the equinox and is strongly associated with Ohigan season. It is often found near graveyards and rice fields, where its bulbs were traditionally planted to deter rodents.
