Shunbun no Hi (春分の日): Celebrating Japan’s Spring Equinox

A Day to Honor Nature, Ancestors, and the Arrival of Spring

Shunbun no Hi (春分の日), or the Spring Equinox Day, is a Japanese national holiday that marks the transition from winter to spring. Celebrated annually around March 20 or 21 (March 20th this year, 2025), this day is not only a natural phenomenon but also a cultural and spiritual event deeply embedded in Japanese traditions. The holiday is a time for people to reflect on nature, honor their ancestors, and welcome the changing seasons.

In Japan, the spring equinox is one of the two times in a year when day and night are nearly equal in length. The other is the autumn equinox, known as Shūbun no Hi (秋分の日). Together, these equinoxes hold great significance in both Shinto and Buddhist traditions, influencing customs that have been passed down for generations.

The Astronomical Significance of Shunbun no Hi

The spring equinox occurs when the sun crosses the celestial equator, making day and night approximately equal in length. This marks the official start of spring in the Northern Hemisphere, as daylight hours gradually become longer.

In Japan, this astronomical event aligns with the country’s deep appreciation for nature. It signals the beginning of warmer weather, the blooming of cherry blossoms, and the renewal of agricultural activities. Farmers historically used this period to prepare their fields for planting, considering it a moment of rebirth and prosperity.

Historical Background of Shunbun no Hi

Shunbun no Hi was originally part of a broader religious observance in Japan. During the Meiji era (1868–1912), it was recognized as an official holiday and became part of Japan’s Shunki Kōrei-sai (春季皇霊祭), a Shinto ritual to honor imperial ancestors.

However, after World War II, under the influence of the U.S.-led occupation, Japan restructured its national holidays to separate religious elements from state affairs. Shunbun no Hi was thus redefined as a secular holiday meant to celebrate nature and living things rather than focus on religious rites. Today, it is primarily associated with personal and familial traditions rather than state-led ceremonies.

Traditional Customs and Activities on Shunbun no Hi

Although Shunbun no Hi is now a secular holiday, many Japanese people still follow traditional customs rooted in Buddhism and Shintoism. Some of the most common observances include:

1. Visiting Family Graves (Ohigan)

One of the most widespread traditions on Shunbun no Hi is Ohigan (お彼岸), a Buddhist practice where families visit their ancestors' graves. This tradition is observed during both the spring and autumn equinoxes.

During Ohigan, people clean the graves, offer flowers, burn incense, and pray for their ancestors. It is believed that during the equinox, the world of the living and the afterlife are closest to each other, making it an ideal time to honor deceased loved ones.

2. Eating Traditional Foods

Special dishes are prepared during Shunbun no Hi, many of which hold symbolic meanings:

• Botamochi (ぼたもち): Sweet rice cakes covered in red bean paste, traditionally eaten in spring. The name comes from the "botan" (peony), which blooms in the season.
• Sansai (山菜): Wild mountain vegetables, which symbolize the renewal of life.
• Tempura: Seasonal vegetables deep-fried in batter, signifying the abundance of spring harvests.

These dishes not only reflect Japan’s culinary heritage but also serve as a way to appreciate nature’s gifts.

3. Enjoying Nature and Hanami (Flower Viewing)

Since Shunbun no Hi coincides with the start of spring, many Japanese people spend the day outdoors, appreciating the beauty of nature. Activities such as Hanami (花見), or cherry blossom viewing, begin in late March and continue through April.

Families, friends, and coworkers gather under blooming cherry trees in parks, enjoying picnics and celebrating the arrival of warmer weather. This tradition embodies the Japanese concept of mono no aware (物の哀れ), which acknowledges the fleeting beauty of nature.

Modern-Day Observances and Cultural Relevance

In contemporary Japan, Shunbun no Hi is a public holiday, meaning schools, government offices, and many businesses are closed. The day is often spent with family, taking short trips, or simply relaxing at home.

With the rise of environmental awareness, Shunbun no Hi has also become a time for ecological appreciation. Many organizations host events promoting sustainability, tree planting, and environmental clean-up efforts, aligning with the holiday’s theme of respecting nature.

Additionally, social media has transformed how people celebrate Shunbun no Hi. Many share photos of cherry blossoms, home-cooked seasonal dishes, and their visits to ancestral graves, keeping traditions alive in the digital age.

A Cultural Celebration of Life, Nature, and Renewal

Shunbun no Hi is more than just a national holiday in Japan—it is a cultural celebration of life, nature, and renewal. Whether through traditional customs like Ohigan, seasonal foods, or outdoor activities, the holiday serves as a reminder to appreciate the balance between the past and the future.

As Japan continues to modernize, the significance of Shunbun no Hi remains deeply rooted in its history and traditions. Whether through small personal rituals or grand cultural festivities, the spirit of this day endures, reminding everyone of the beauty of spring and the importance of honoring both ancestors and nature.
