Light of Vernal Equinox: Celebrating Shunbun no Hi in Japan
As winter retreats and the harsh cold gives way to a gentle warmth, the light in Japan shifts. It is not merely a change in temperature, but a distinct alteration in the quality of the atmosphere—a phenomenon poetically referred to as the “Light of Vernal Equinox.” In Japan, the arrival of spring is marked formally by Shunbun no Hi (Vernal Equinox Day), a public holiday that celebrates nature and honors the spirits of ancestors.
For the culturally curious traveler, this period offers a profound look into the Japanese soul, where the reverence for the changing seasons intertwines with deep spiritual obligations. It is a time when the day and night are of equal length, symbolizing a perfect equilibrium in the cosmos.
The Origins: Balancing the Cosmos
Shunbun no Hi became a secular public holiday in 1948, defined legally as a day to “praise nature and cherish living creatures.” However, its roots run far deeper, entangled with the ancient traditions of Shintoism and the spiritual framework of Buddhism.
Before the modern era, this period was closely linked to Shunki Koreisai, an Imperial court festival dedicated to the worship of past emperors. Yet, for the common people, the equinox has always been synonymous with Ohigan.
Ohigan is a seven-day period surrounding the equinox. The word translates to “the other shore.” In Buddhist thought, the Sanzu River separates the world of the living (this shore) from the world of the dead (the other shore). It is believed that during the equinox, when the sun rises exactly in the east and sets exactly in the west, the distance between these two worlds is at its shortest, allowing for a clearer connection between the living and the departed.
Legend and Spiritual Significance
The “Light of Vernal Equinox” is not just a meteorological observation; it is a spiritual beacon. The legend of Ohigan is deeply tied to the concept of the Pure Land (Jodo). Since the sun sets directly in the west on this day, devout Buddhists traditionally believed that by gazing at the setting sun, they were looking directly toward the Western Paradise of Amida Buddha.
Historically, this alignment of light served as a meditative guide. It was a time to reflect on the Six Paramitas (perfections) of Buddhism—generosity, morality, patience, vigor, concentration, and wisdom—to navigate the “river” of suffering and reach enlightenment. While modern celebrations may feel less esoteric, the underlying sentiment remains: the light of the equinox is a guide leading spirits home and helping the living find balance.
Modern Culture: How Japan Celebrates
Today, the “Light of Vernal Equinox” signals a quiet, family-oriented observance rather than a loud festival. The most common custom is Haka-mairi (visiting the family grave).
During this week, cemeteries across Japan are filled with the scent of incense. Families clean the gravestones of their ancestors, offer fresh flowers, and pray for the peaceful repose of the spirits. It is a time of reunion, not of mourning, where the continuity of family lines is celebrated under the brightening spring sky.
The Taste of Spring: Botamochi
No Japanese seasonal event is complete without specific cuisine. During the spring equinox, people eat Botamochi. This is a sweet rice cake made from glutinous rice wrapped in red bean paste (anko).
Interestingly, the same cake is eaten during the Autumnal Equinox but is called Ohagi. The difference lies in the name’s origin: Botamochi is named after the Botan (peony), which blooms in spring, while Ohagi is named after the Hagi (Japanese bush clover) of autumn. The red beans are believed to ward off evil spirits, protecting the family during this transitional period.
Traveler’s Tips for the Equinox
If you find yourself in Japan around March 20th or 21st, you have a unique opportunity to witness a serene side of the culture.
- Temple Visits: Visit major temples like Shitenno-ji in Osaka, which holds special services where the setting sun aligns with the temple’s Torii gate, recreating the visualization of the Pure Land.
- Garden Viewing: While cherry blossoms (sakura) might be just beginning to open, plum blossoms (ume) are often in full glory. Visit landscape gardens to see how the “Light of Vernal Equinox” illuminates the carefully pruned aesthetics.
- Etiquette: If you visit a cemetery, remember it is a place of worship. It is polite to observe from a distance. Do not take photos of families praying or specific names on gravestones without permission.
- Seasonal Eating: Visit a local Wagashi (Japanese sweets) shop and ask for Botamochi. It is a delicious way to participate in the season.
