What happened
"Taisho Democracy" describes the flourishing of new political thinking, social movements, and party politics centered on the reign of Emperor Taisho (1912-1926). From 1924 to 1932, seven successive cabinets were formed by political parties, described at the time as "the normal course of constitutional government," and in 1925 the Kato cabinet passed a law eliminating tax requirements for voting, extending suffrage to all men over 25. This democratic momentum was violently reversed: in the May 15 Incident of 1932, an attempted coup d'etat, young naval officers assassinated Prime Minister Inukai Tsuyoshi, and in the February 26 Incident of 1936, another failed but destabilizing coup attempt by army officers, after which, in Nippon.com's assessment, "all hope of a return to 'the normal course of constitutional government' was lost."
Why it matters
The collapse of party government under military pressure in the early 1930s cleared the way for the army and navy to dominate Japanese policy through the following decade, directly enabling the invasion of Manchuria and the militarist drift toward the Pacific War.
How we know
The suffrage reform, the sequence of party cabinets, and the two coup attempts are documented in Japanese political and legal records from the period, including the 1925 suffrage law itself.
