What the Spring Equinox Means in Japan
In Japan the spring equinox is known as Vernal Equinox Day (春分の日, Shunbun no Hi). It is a national public holiday, falling on the date of the astronomical vernal equinox, which in the modern calendar usually occurs on 20 or 21 March. Because the holiday is tied to an astronomical event rather than a fixed calendar date, the exact date is officially determined and announced in advance each year.
The day sits within Higan (お彼岸), a seven-day Buddhist observance period that centres on the equinox. Higan literally means "the other shore," referring in Buddhist thought to the far shore of enlightenment, reached by crossing the river of worldly suffering. The equinox is regarded as the moment when day and night are in balance, and this balance is symbolically linked to the harmony needed to cross from the near shore of delusion to the far shore of awakening.
Origins
The spring and autumn equinoxes have been observed in Japan since ancient times as Higan, with the spring period called Haru no Higan (春彼岸) and the autumn period Aki no Higan (秋彼岸). The observance is rooted in Buddhist practice, particularly the idea of honouring ancestors and reflecting on impermanence.
Vernal Equinox Day became a modern national holiday in 1948, under Japan's post-war holiday legislation. Unlike some Japanese holidays that retain a specific civic or imperial association, it is generally treated as a day for nature appreciation and for family and ancestral remembrance.
Customs and Traditions
The central customs of the season are associated with Higan rather than with the single holiday date alone.
- Grave visits (ohaka-mairi): Families visit family graves to clean the stone, offer flowers, and pay respects to ancestors. This is one of the most widely observed practices of the period.
- Home altars (butsudan): Offerings are made at household Buddhist altars, and sutras may be recited.
- Temple observances: Buddhist temples hold services during Higan, and some hold memorial ceremonies for ancestors.
- Seasonal greetings: It is customary to exchange Higan greetings with relatives and acquaintances, particularly in connection with grave-visiting.
The holiday itself is not marked by large-scale public festivities of the kind associated with New Year or summer festivals. For many people it is a quiet day off, often spent with family or used for outings to view early spring scenery.
Food and Drink
Certain foods are strongly associated with Higan, and by extension with the equinox period.
- Botamochi (牡丹餅): Sweet rice balls coated in red bean paste, traditionally eaten during the spring Higan. The name refers to the peony (botan), a flower associated with spring. The same confection is called ohagi in autumn, named after the bush clover (hagi).
- Ohagi: The autumn counterpart of botamochi; the two names refer to essentially the same sweet.
- Inari sushi: In some regions, seasoned rice stuffed in fried tofu pouches is prepared during Higan, reflecting the connection between the period and Inari shrines.
- Seasonal ingredients: Spring vegetables and wild mountain vegetables (sansai) feature in home cooking at this time of year.
These foods are offered at household altars and graves as well as eaten, linking the culinary tradition to the ancestral focus of the period.
Religious and Civic Observances
Vernal Equinox Day is a secular public holiday, but its timing within Higan gives it a distinctly Buddhist character in practice. The main religious activity is ancestral memorialisation at temples and at family graves. Some temples hold Higan services, and it is common for families to have a Buddhist priest visit the home or the grave.
Civically, the day is simply a national holiday. Government offices, schools, and many businesses close. Because it falls in the middle of a week in some years, it can create a long weekend, and it is also associated with the end of the school year and the beginning of spring break in many parts of the country.
Regional Variations
The core practices of Higan — grave visits, altar offerings, and the eating of botamochi — are observed across Japan, but local customs differ in emphasis and detail.
- Kansai and Kanto: The distinction between the names botamochi and ohagi is sometimes described as regional, with one term favoured in eastern Japan and the other in western Japan, though usage overlaps and varies by household.
- Rural areas: In farming communities, the equinox period has traditionally been linked to agricultural cycles and to prayers for a good harvest, alongside the ancestral observances.
- Urban areas: In large cities, observance tends to be more limited to grave visits and the purchase of seasonal sweets, with less emphasis on extended family gatherings.
Because the holiday is tied to the equinox rather than to a fixed date, the exact day of observance shifts slightly from year to year, and local temple and community schedules adjust accordingly.
Summary
In Japan, the spring equinox is both a national holiday and the centre of the Buddhist Higan period. Its meaning combines nature appreciation, the symbolic balance of day and night, and the remembrance of ancestors. Customs centre on grave visits and household altars, food traditions revolve around botamochi and related sweets, and public life is marked mainly by a quiet day off rather than by large festivities. Regional differences exist in naming, food customs, and the emphasis placed on agricultural and ancestral elements, but the essential character of the observance is shared nationwide.
