The hanto is the hosts assistant. Most temae does not require a assistant, but some few does:
- Kinin date Koicha and Usucha
In addition to the special tasks in the above mentioned temae the hanto generally helps the host make the event flow, and will on occasion bring items into the room and give to the guests.
During larger chakai the hanto may also be the person in charge of explaining what is happening and telling the guests about the utensils while the teishu does the temae.
