A kamidana is a small Shinto altar found in Japanese homes, used to honor and worship the kami, or spirits. Typically placed on a shelf or in a dedicated space, it serves as a focal point for daily rituals and offerings. The kamidana often contains sacred objects, such as a small mirror, rice, and salt, which symbolize purity and the presence of the kami. Families may perform simple rituals at the kamidana, such as offering food, incense, or prayers. This practice helps to foster a connection with the spiritual world and is an important aspect of Japanese culture and tradition.
