Dersu Uzala is an amazing film by Kurasawa shot in eastern USSR as was, in the 70's, and in Russian. Filmed in 70mm (needs to be seen on a big screen, ideally) and is a story about friendship, and nature, and impermanence.
Why Has Bodhidharma is a Korean film with hardly any dialogue, about a young monk living with an old monk (and an orphan boy) in a rural monastery - and oddly enough, is also about friendship, and nature, and impermanence. Very slow moving and very, very beautiful.
I've not liked all of Miyazake's films - I didn't like Nausicäa, for example, but that's because <geek alert> the 7-volume graphic novel it was based on is approximately five million times deeper and more amazing </geek alert>. I love Princess Mononoke though, mainly for The Spirit of the Forest.
