Thanks.
Having another go. This time river pirates attack a sekisho (toll gate) guarded by a group of ashigaru. The ashigaru turn out to be more numerous than the pirates thought...




This game didn't have any specifically Japanese features. With taking heads and 'first spear' type rewards not very appropriate for this kind of fighting, and without strict feudal relationships, there really isn't much to distinguish the fighting from Western medieval.
Incidentally, I'm still playing the game on a grid instead of using measured movement.
