More subtle etiquette

From "Aikido for beginners," "The Dojo Layout and Structure of Place"

Joseki (上席) – consisting of the kanji for “top” and “seat” (as in a place for sitting), this is the “most comfortable seat in the house” and is a term used in general Japanese etiquette. For example, the dinner table, train and taxi will have joseki. In a taxi it is the seat right behind the driver (first to get in and last to get out) and in a train it is the window seat facing the direction of travel (second place goes to the other window seat if there are facing seats). Other sources, including the discussion on Salmon-sensei’s blog, states this is the lateral wall adjacent to the kamiza and furthest away from the door. I somewhat disagree that this is the exact definition of the joseki though for convenience’s sake I will also refer to this wall as the “joseki” wall. However, in my view, rather than it being a wall, it is an orientation vaguely towards that corner but in front of the sensei, since joseki is one extreme of a continuum to the shimoseki (more on this below). If the entrance were on the right/east side of the dojo, then the joseki would be towards the left/west side. The joseki is where a VIP will sit, such as a visiting high grade sensei, dignitary or someone more senior in the organization who does not necessarily take part in the training (e.g. school principal, company president, police superintendant, etc.). Sometimes a resident sensei may sit here but from what I can tell, this is usually only the case if the resident sensei is a higher grade than the dojo leader sensei.

Something to remember when going out to eat or traveling with Senseis.
