Kamiza

nihongo|"Kamiza"|上座| is a term used in Japan to refer to the 'top seat' within a room. The opposite term referring to the 'bottom seat' within a room is "Shimoza". The Kamiza is the seat or position that is most comfortable, usually furthest from the door (because this is warmest). In a traditional Washitsu room it would often be a Zabuton placed so the person sitting there has their back to the Tokonoma. In a modern, Western-style room it would often be a comfortable armchair or sofa.

When entering a room in Japan on a formal occasion it is of great importance to assume the correct seating position, and to leave the Kamiza free for the most important person present, be that a special guest or the person of highest rank. However, if one humbly sits in the Shimoza position and is then encouraged by the host to move to the Kamiza, it is quite acceptable to do so.

The term Kamiza is frequently confused by martial arts practitioners with Kamidana, a Shinto shrine often found in Dōjō (martial arts training halls).
