Punctuality is taken extremely seriously in Japan. American pop culture is en vogue in Asia. I could sell my old high school gym shorts in Japan if I hadn't thrown them away. China and Taiwan have guns pointed at each other. In addition, Taiwan does not respect American copyright laws.
Red tide is really red.
I know everything on this list is a lesson that you knew or learned as well. But it was fun and fascinating to learn them for myself. The cities in Japan were the most modern I have ever seen. They show amazing uses of space and people moving. Conversely, the cities in China were extremely crowded and old, although, one cannot forget the Pudong district in Shanghai where it seems the old was leveled in order to create a new modern district.
