In Komatsu Obon takes place from August 13 to August 15. This time is intended to convey respect to one's ancestors. During this time the ancestors come to visit. There are extra decorations in the room where the Buddhist altar is located and at some point a priest pays a visit.
On August 16 the ancestors return. The earlier the family gets to the "tera" or temple and to the family grave site, the better the position of the ancestors in heaven.
