I've watched Heaven and Earth (Ten to Chi to).
It's about two samurai warlords fighting each other. One is Takeda Shingen who is ambitious and wants to conquer all the Japan. The other is Kagetora (better known in history as Uesugi Kenshin) who is just dedicated to defedning his province.
I don't think I want to talk much about this movie but one thing stands out, and that it's complete lack of CGI. There are big battles portrayed and it was all shot with real people and horses and that is just amazing to see on its own. Also samurais are cool.
