So... in other words your making yet another site about anime then throwing in some historical references to samurai and a few periods and calling it Japanese culture.
Want some ideas? Here is one: try something that hasn't been done to death 1 billion times. A site on women's life style in Japan, earthquakes and how they are dealt with and prepared for in Japan, Japan's education system, or modern NON-ANIME Japanese literature published internationally. Please, ADD something new to the information on society, life, and culture in Japan...
Nah, that would be too hard. Just post some anime jpgs and a few wikipedia links.
(Yes, it is that time of the week for me. Male PMS.)
