We come to Japan expecting a beautifully designed motherboard in which every part of the circuit works flawlessly. And after half a lifetime in Japan, I count on such precise procedure as if I were Japanese myself. Yet the system operates to perfection only so long as everybody knows the rules. Once the smallest malfunction (or outsider) shows up, the effect is like a concertina crash on a freeway, in which each car smashes into the one in front of it and the collateral damage spreads, unsettlingly. Japan has trained all of us to deal with everything except exceptions.
