What is Seimei (清明)?

Seimei, also known as Qingming in Chinese and sometimes referred to as the "Clear and Bright Festival," is a traditional East Asian festival observed in countries like China, Japan, and Korea. In Japan, Seimei marks one of the 24 solar terms (節気 sekki) in the traditional East Asian lunisolar calendar. It usually falls around April 4th to 6th, signaling the full arrival of spring.
The term "清明" literally translates to "clear and bright." This reflects the clarity of the spring sky and the purity of nature as everything begins to bloom. The air becomes fresh, the sun shines
brighter, and flowers like cherry blossoms begin to reach full bloom.
Japanese seasonal calendar

The and the 24 Solar Terms
Japan adopted the solar-based Gregorian calendar in 1873, as the Meiji government implemented modernizing measures to align Japan with the West. Prior to that, Japan used a lunisolar calendar, based on the rhythms of the sun and moon. But as the old calendar shifted 11 days each year, it gradually conflicted with eclipses and other astronomical events, disrupting agriculture and daily life.https://www.group-shinka.com/culture/vernal-equinox-day-japan
Today, Japan celebrates events such as Christmas and Valentine’s Day on fixed calendar dates, but in the past, when most people relied on agriculture for their livelihood, they needed a guideline for when to plow the fields, plants seeds, and so on. The 24 solar terms were therefore used to help people align their lives to the seasons.https://www.group-shinka.com/culture/shubun-no-hi
The traditional Japanese calendar marks the passing of the seasons and changes in the natural world through the names given to different times of year. There are 24 major divisions, or sekki, from Risshun (Beginning of spring) in early February until Daikan (Greater cold). Originally taken from Chinese sources, these are still well-known around East Asia.https://www.group-shinka.com/culture/risshun-japan
The 24 divisions are each split again into three for a total of 72 kō that last around five days each. The names were also originally taken from China, but they did not always match up well with the local climate. In Japan, they were eventually rewritten in 1685 by the court astronomer Shibukawa Shunkai. In their present form, they offer a poetic journey through the Japanese year in which the land awakens and blooms with life and activity before returning to slumber.
The dates in the following table are approximate and may vary by one day depending on the year. There are no standard readings in Japanese for the kanji names of the 72 kō, so other sources may give different readings.
Seimei in Japanese Culture

While Seimei is not a major festival in Japan compared to its significance in China, it is still recognized in traditional calendars and is used by farmers and seasonal planners. It symbolizes a time of balance and renewal, encouraging activities such as:
Spring cleaning and purification
Outdoor walks and picnics
Observing and respecting nature’s rebirth
In traditional Japanese aesthetics, Seimei aligns with wabi-sabi, celebrating the simple, transient beauty of the season.
