I thought the title of this thread was rather ironic . . .
Haji (shame) is said to form the core of Japanese culture. Japanese culture is described as "shame culture " in contrast to Western "guilt culture". In the west one can say that one's behavior is based, or dictated, by a sense of guilt resulting from one's actions. The feeling of guilt in the west is an internal feeling; the feeling of shame in Japan is an external feeling. This is not to suggest that the west is shameless, but rather that historically, Japan, has placed a great deal upon the feeling of shame. One can look to the samurai period for an example of shame. For a samurai, being put to shame in front of the public was as good as death.
Lexus' design of their large sedans has never been particularly unique. Until recently, they were MBesque, so perhaps we should consider this a sign that the 7 is now the design standard for large luxury sedans?
