I pronounce
Johanna the same way as you pronounce
Joanna: jo-ANN-a. I also pronounce Johannah as jo-ANN-a, though I'm not sure how correct that is. The only time I've heard the Jo-Hannah pronunciation is on the Duggars' show; it sounds comical at best, and hickish and ignorant at worse. My favorite spellings are
Johanna and
Joanna.
ETA: I'm from the U.S.
