English labels such as captain or rear admiral are equivalents rather than literal translations of Imperial Japanese Navy ranks. The Japanese system distinguished developing tactical officers from the flag ranks trusted with wider strategic command. Reading Mikawa's appointments against that structure shows him taking teaching and command posts slightly earlier than a routine career would suggest. His service was being deliberately broadened to prepare him for senior rank rather than simply advancing by time served.
