At its conclusion, a practitioner of shugendo, a syncretic tradition combining elements of Buddhism and Shinto, serves as priest to send off the spirits of ancestors past that have journeyed back for Obon as well as the new spirits of those deceased within the past year. The spirits ride the flames of faceted lanterns that are lit and drift off into the eastern sky.
