Shinto and Buddhism are Japan's two major religions. Most of the Japanese consider themselves Buddhist, Shintoism or both. Usually there is a large red gate in front of the Shinto shrine calls "Torii"

Kamidana is usually displayed on the high shelf of the house.
Sometimes Kamidana may also include a shimenawa, a sacred rope of twisted rice straw traditionally used to demarcate a sacred area. They also offer water, sake (rice beer), food, and green twigs which are placed daily at the front of the shrine. When you pray for Kamidana, first bow twice and then clap your hand twice, then you pray, and after that you bow once.
