Launch of Japan's first Shinkansen extension planning

On June 12, 1965, Japanese National Railways initiated detailed planning for Tokaido Shinkansen extensions beyond Tokyo-Osaka. This built on the 1964 debut of the world's first high-speed line, using advanced 0 Series trains capable of 210 km/h. Key figures like engineer Hideo Shima addressed seismic challenges with elevated viaducts and earthquake detection. The project symbolized Japan's post-war economic miracle, reducing Tokyo-Osaka travel to under three hours and spurring tourism and business. It established global standards for bullet trains, inspiring networks in Europe and Asia with emphasis on punctuality and safety.
