Shunbun, or the Spring Equinox, is a traditional Japanese holiday that occurs around March 20th or 21st each year. It marks the moment when day and night are approximately equal in length, signaling the arrival of spring. This day is significant for celebrating nature and the changing seasons. During Shunbun, families often visit the graves of their ancestors to pay respects and clean the burial sites. It is also a time for enjoying the beauty of cherry blossoms, as many people participate in hanami (flower viewing) picnics under blooming trees, embracing the renewal of life and the warmth of the season.
