Your description of Monterey, California as “west” and Tokyo as “east” is correct, but why on earth would you pick 180° longitude as the dividing line? The dividing line between east and west is well defined – it’s the Prime Meridian at 0°. That’s the point where longitude coordinates in the two directions become positive or negative, or, depending on your preferred convention, become designated “E” or “W”. I don’t know what this ongoing fascination with 180° comes from. Maybe it’s confusion with the International Date Line.
