The spirits of ancestors are said to come to the family grave during the Bon festival. At the end of the festival season, the Ani Buddhist Society launches paper lanterns down the river to help guide the spirits on their journey back to the other world. Afterwords, a fireworks show is held along the banks of the river. The lanters are launched at 18:00 and the fireworks starts 18:30. The festival grounds are located just a five-minute walk from Aniai Station.
