Higan(お彼岸?) is a Buddhist holiday exclusively celebrated by Japanese sects during both the Spring and Autumnal Equinox. It is observed by nearly every Buddhist school in Japan. The tradition extends from mild weather that occurs during the time of equinoxes, though the origin of the holiday dates from Emperor Shōmu in the 8th century. People who normally worked in the fields had more leisure time to evaluate their own practices, and to make a renewed effort to follow Buddhism. Today, special services are usually observed in Japanese Buddhist temples, and Japanese temples abroad, based on the particular Buddhist tradition or sect.
