Iemoto
The Main Gate of the Omotesenke Tea Lineage
A number of subsidiary families may be linked to a main house. The main house has the overall obligation to:
1. maintain the family line biologically (or through adoption),
2. perform memorial rites for the ancestors, and
3. ensure the economic survival of the group.
The main house is called the honke or iemoto.
