📜 3. Historical Background
Originates from Japan’s first railway between Shimbashi and Yokohama, opened in 1872
In the Meiji period, it was developed roughly along the historic Tokaido road (the 53 post stations) as the main Pacific-side trunk line
After World War II, limited express trains and later the Tokaido Shinkansen appeared, leading to a functional split between high-speed and conventional lines
Today it still plays a dual role:
Core commuter route in major metropolitan areas
Key connector between regional cities
