Kamidana

Kamidana (神棚 in Japanese), literally meaning "kami shelf", is a type of miniature shrine placed or hung high on a wall in some Japanese homes. The kamidana contains a wide variety of items related to the Shinto style ceremony. Worship at the kamidana is as simple as saying prayers, offering food (i.e., rice, water, etc.) and flowers. Before worshipping at the kamidana, it is ritually important for family members to cleanse their hands.
