List of Japanese prime ministers by longevity
This is a list of Japanese prime ministers by longevity. It consists of Prime Ministers and Interim Prime Ministers of Japan who have held the office. If a Prime Minister served more than one non-consecutive term, the dates given are for the beginning of their first term, and the end of their last term.
To avoid confusion and maintain consistency, the name of the Prime Ministers are listed in the Western style (given name, family name). Where the person in question is still living, the longevity is calculated up to 17 February 2017.
