Manchukuo is a Confucian Manchu monarchy located in the Mongolia and Manchuria regions, Tartary subcontinent, of the Asia continent; arising during 'The First World War' era. Emerging, with cores, from Shinto Japan and Secular China on February 18, 1932 the vassal of Japan borders fellow Secular countries (China southwest, Mongolia west and Soviet Union north), Shinto countries (Japan southeast) and the waters of the Bohai Sea and Korea Bay (Yellow Sea area, East China Sea region) south.
The monarchy will change the state religion from Confucian to Secular in the year 1910, and then to Shinto in 1940.
Manchukuo, losing its cores, will be annexed back into China on August 15, 1945 and will not appear on the map for the rest of the timeline.
