Kato Takaaki

Kato became Prime Minister in June 1924, leading a coalition cabinet of the Kenseikai, Seiyukai, and Kakushin clubs. This government, known as the 'Mitsubishi Cabinet' due to Kato's ties to the Mitsubishi zaibatsu, pursued moderate foreign policy and domestic reforms.

As Prime Minister, Kato Takaaki pushed through the Universal Male Suffrage Law, which abolished tax-based voting qualifications and granted voting rights to all male citizens aged 25 and over. This expanded the electorate from about 3 million to over 12 million, marking a major step toward democracy in Japan.

Kato's government also enacted the Peace Preservation Law, which criminalized advocating for the abolition of private property or altering the national polity. This law was used to suppress leftist political movements and marked a turn toward authoritarianism.

Kato's government signed the Soviet-Japanese Basic Convention, establishing diplomatic relations with the Soviet Union. Japan recognized the Soviet government and withdrew troops from northern Sakhalin in exchange for oil and coal concessions.

Kato Takaaki died of pneumonia on January 28, 1926, while still serving as Prime Minister. His death ended the Kenseikai-led government and marked the end of the Taisho Democracy era's reformist momentum.
