Kamiza
Kamiza (上座) is the Japanese language term referring to the "top seat" within a room, meaning the place of honor; the term also applies to the best seats in air-planes, trains, and cars. The antonym, meaning "bottom seat," is shimoza (下座). In a room, the kamiza is the seat or position that is most comfortable, usually furthest from the door -- because this is warmest, and was safest from attack back in the feudal period. In a traditional washitsu room it would often be a zabuton placed so the person sitting there has his back to the tokonoma; the kamiza is the spot closest to the tokonoma or simply farthest from the door in a room lacking a tokonoma. In a Western-style room it would be a comfortable armchair or sofa, or the head of a table. The term is general, and does not only apply to Japanese culture.
Choosing a seat
When entering a room in Japan on a formal occasion, participants are expected to assume the correct seating position, and to leave the kamiza free for the most important person present, either a guest of honor or the person of highest rank. However, if one humbly sits somewhere indicative of lower status and is then encouraged by the host to move to the kamiza, it is acceptable to do so.
The best seats in a car in descending order of rank are: directly behind the driver, behind the front passenger, in the middle of the back seat, front passenger seat, driver. In air-plane or train passenger seating, the "top seat" is the window-side, followed by the aisle seat and then the middle seat.
In dojo
In the dojo (training halls) of many Japanese martial arts, the kamiza is the location of a small Shinto shrine which is called a kamidana. [1] [2] [3] [4] The front of the dōjō may also simply be called "front" (正面 shōmen) or the shinza.
