The Imperial Household and Uji clans believe in ancestor gods from a long time ago. They are considered the god or person that started the family line. The clan is a group of people who feel like they are family because they have the same ancestor god. This idea used to be very important, but over time it became less important. The clan gods used to be based on family ties, but later became more connected to the land they lived on, and were like other local gods.
