Zipang - Anyone seen this?
It's basically about a modern japanese battleship and crew suddenly jumping into the timeline of WWII out in the Pacific, and they have to choose between joining the US or Japan--or maybe neither. *sly smile* It's 26 episodes of decent--not that good, but not bad either--animation. More like a drama, actually--and it doesn't really bash, nor is it propaganda or too biased, about the japanese part in the war. (You'll prolly find the subs over at animesuki.)
Nothing compared to Last Exile, though.
