Kagamimochi-kai is a traditional Japanese event that celebrates the New Year by honoring the Kagamimochi, a decorative rice cake. This event typically involves the preparation and display of Kagamimochi, which consists of two round rice cakes stacked on top of each other, often topped with a bitter orange called daidai. The Kagamimochi symbolizes prosperity and good fortune for the coming year. During the Kagamimochi-kai, families and communities gather to appreciate the Kagamimochi and partake in various activities, such as sharing food and engaging in traditional games. The event emphasizes the importance of family bonds and cultural heritage, fostering a sense of unity and celebration as the New Year begins.
