Autumnal Equinox Day

Autumnal Equinox Day, known in Japan as Shūbun no Hi (秋分の日), is a national holiday that falls on or around September 23 each year, marking the astronomical start of autumn. Established as a public holiday in 1948 under the postwar Constitution, its origins lie in the ancient Japanese tradition of Higan (彼岸), a week-long Buddhist observance centered on the equinox. Higan, meaning 'the other shore,' symbolizes the passage from the world of suffering to enlightenment. During this period, families pay respects to their ancestors by visiting graves, offering prayers, and cleaning family altars. The holiday was originally a Shinto harvest festival called Aki no Higan, but after World War II it was secularized to honor the change of seasons and promote appreciation of nature. In 2026, the Autumnal Equinox occurs on September 23, continuing a legacy that blends seasonal reverence with deep family ties.

Central to Shūbun no Hi is the practice of ohaka-mairi (お墓参り), or grave visitation. Families travel to cemeteries to clean tombstones, offer flowers, incense, and water, and recite Buddhist sutras. At home, many set up a small butsudan (Buddhist altar) with offerings of seasonal fruits, rice balls, and sweet bean cakes called ohagi (おはぎ). Ohagi, made from glutinous rice and coated with sweet bean paste or kinako (soy flour), is the quintessential food of the holiday, symbolizing the harvest and the bond between the living and the dead. Public celebrations are minimal, but some communities hold seasonal festivals featuring traditional dances and local foods like chestnuts and sweet potatoes. A common greeting is 'Shūbun no Hi omedetō gozaimasu' (秋分の日おめでとうございます) to wish others a peaceful equinox, though many simply acknowledge the day with quiet reflection. Schools and businesses are closed, allowing families to spend time together hiking to enjoy the autumn colors of momiji (maple leaves) or visiting parks.
