Tōkaidō Shinkansen Extension Opens

On July 23, 1967, Japanese National Railways opened the 160 km extension of the Tōkaidō Shinkansen from Shin-Ōsaka to Okayama, further solidifying the world's first dedicated high-speed rail corridor. The extension allowed 0 Series trains to operate at 210 km/h over the new alignment, dramatically cutting travel times between Tokyo and western Japan. Engineered with advanced earthquake detection and aerodynamic designs, the line overcame mountainous terrain and dense urban areas. The project demonstrated Japan's post-war technological resurgence and influenced high-speed rail development worldwide. Today the corridor carries over 150 million passengers annually and remains a benchmark for efficient, safe, and punctual rail travel.
