On November 4, 1921, the rhythm of modern Japan stopped cold at Tokyo Station. Prime Minister Hara Takashi, the first commoner ever to lead the nation, was on his way to Kyoto when a railway worker stepped from the crowd and plunged a knife into his chest. In an instant, Japan’s fragile experiment with democratic, party-based government came undone. Hara had been called both the father of constitutional politics and the boss of a corrupt machine, a realist who believed democracy could work only if people learned to listen. His murder exposed the fault lines of a country still torn between samurai pride and parliamentary progress. Tonight on Dave Does History, we tell the story of the man who tried to build Japan’s first democracy, the assassin who ended it, and how his death set the nation on a road that led, inexorably, toward war.
