In ancient India for the enthronement of a king or the investiture of a crown prince, water was brought from the four seas and sprinkled on his head. This was incorporated into Buddhism, in the form of a ritual that symbolized the various Buddhas sprinkling wisdom water on the head of a bodhisattva who had newly attained the tenth level of enlightenment. The ceremony is particularly important in esoteric Buddhism, where parishioners undergo a kechien kanjō when they join the faithful, and a denpō kanjō when they attain the level of Ajari and are initiated into the secret teachings. Among the Shōsō-in treasures, there are particularly large banners, known as kanjō-ban that decorated the temple for kanjō ceremonies.
