Minor nitpick - he mentions the concept of Shame Cultures vs. Guilt Cultures and mentions the Japanese as a Guilt Culture, along with the European cultures. But this concept was first popularized in a book by Ruth Benedict called the Chrysanthemum and the Sword, where she claims that Japanese culture is a Shame (haji) culture where social norms are primarily enforced by fear of ostracism ("Nobody will be your friend/help you if you act like that!") versus internalized fears in a Guilt culture ("God will punish you if you act like that!"). It was written in the late 40's and it's been criticized by Japanese and others, but that's where the idea comes from.
