Johansen's shot went over Luongo's right shoulder in the fourth round of the shootout for the only score in the tiebreaker.
The 55 shots were a season-high for the Panthers and also the most given up by Columbus.
The Blue Jackets won for the second time in eight games and stretched their win streak against Florida to 10 games. The Panthers haven't beaten Columbus since Nov. 21, 2007.
