It is Player A's turn and he has a province with Plains of Otosan Uchi, one the cards is Hida Yamadera. Player B destroys the Plains of Otosan Uchi in the Action phase. During the battle phase, Player A uses Duty of the Crab to bring Yamadera into play. Does the province still refill face up per Yamadera's reaction?

Per the CR on Refill, affects like Yamadera will only affect a province that is momentarily empty. Since this isn't the case in the situation you described, Yamadera will have nothing to refill.
