Japanese Cabinets and Cabinet Ministers Database

The Japanese Cabinets and Cabinet Ministers (JCCM) Database contains a wide range of data pertaining to the 141 cabinets formations, 1,350 individuals appointed to ministerial posts, and 3,612 portfolios allocated between July 1871 and May 2013. In delineating cabinet formations and dissolutions, I followed the system employed by the Government of Japan, which provides a complete listing of cabinets, portfolios allocated, and the names and the dates of appointment and dismissal of all ministers from December 22, 1885 to the present (http://www.kantei.go.jp/jp/rekidai/index.html). The JCCM Database deviates from that system in that it begins with the de facto cabinets that emerged within the Grand Council (Dajōkan) beginning in July 1871.
