Aki (秋) is the Japanese word for "autumn" or "fall." It signifies the season that follows summer and precedes winter, typically occurring from September to November in Japan. Aki is characterized by cooler temperatures, changing leaves, and harvest festivals, making it a time of natural beauty and cultural significance. In Japanese culture, Aki is often associated with various traditions, such as the celebration of Tsukimi, the moon-viewing festival, where people admire the full moon and enjoy seasonal foods. The season also brings an abundance of harvests, including rice and persimmons, which are celebrated in many local festivals.
