I don't think it is, although the Japanese "do" arts may have a particular flavor in how they express those concepts. (If it was unique to Japanese arts, then it would raise the question of what distinguishes traditional arts from China, Korea, Thailand, Indonesia, Europe, etc.)I suppose I presumed (perhaps erroneously) that since Japanese arts such as flower arranging, tea-making, and calligraphy offer a 'deeper interpretation' or a 'way' (do), it was unique to Japanese (or Okinawan) martial arts.
The details you offered I don't believe are culturally specific. I do think they are reflective of how a particular individual may approach their study of the martial arts. You and I may appreciate those aspect of training, but I've known lots of karateka and lots of BJJ practitioners who do not. I've also known plenty of people in a variety of arts who do give lip service to similar concepts but you couldn't tell it by watching how they live or train.
