Honestly, I cannot claim to have any indepth knowledge of Japan. But there are little patches here and there. I know there is a high level of technology there presently. Animes too do not cease to come to mind. Also the legendary movies about the Samurai remind us of the high regard for honor in Japanese culture. Just like most big Asian countries, martial arts seemed to be a major part of Japan's history. But sadly their role in the Second World War 2 also comes up. The tale of the Kamisake pilots and how they were ready to forego everything for country. In short, there are indeed many interesting things that come to mind.
