Tokaido Shinkansen Extension

The extension of the Tokaido Shinkansen to Okayama on May 19, 1967, expanded Japan's pioneering high-speed rail corridor beyond Tokyo-Osaka. Built to handle 130 mph operations with advanced aerodynamics and earthquake detection, it featured Series 0 trains that transformed intercity travel. Overcoming mountainous terrain and seismic risks through tunnels and viaducts, this project under JNR boosted economic integration and passenger volumes dramatically. It influenced worldwide high-speed rail adoption, from France's TGV to China's network, symbolizing post-war technological resurgence and efficient mass transit.
