A butsudan is a traditional Japanese altar used in homes to honor and remember deceased ancestors. Typically made of wood, it features shelves for placing offerings such as flowers, incense, and food. The butsudan serves as a focal point for family rituals and prayers, fostering a connection between the living and their ancestors. Inside the butsudan, families often place a small tablet called a ihai, which bears the name of the deceased. This practice is part of the broader Japanese cultural tradition of ancestor worship, reflecting respect and gratitude towards those who have passed away, and is commonly observed during festivals like Obon.
