The Japanese fourth seed was driven to distraction by double-sided Hsieh's angled shots and stout defence, and was staring down the barrel at 4-2 in the second set at Margaret Court Arena.
Hsieh's serve crumbled, however, and Osaka claimed 10 of the last 11 games to close out the match in a barrage of power hitting.
Osaka will play the winner of Wang Qiang and Anastasija Sevastova for a place in the quarter-finals.
