Tokyo Rapid Railway

The Tokyo Rapid Railway (Japanese: 東京高速鉄道) was a private railway operator that built and operated the section of the present-day Tokyo MetroGinza Line between Shimbashi Station and Shibuya Station from 1934 to 1941.
Together with the Tokyo Underground Railway, which opened the line between Asakusa Station and Shimbashi Station as Japan’s first subway section, it formed one of the two principal predecessors of the modern Tokyo Subway.
In 1941, following the outbreak of World War II, it was ultimately merged with the Tokyo Underground Railway into the Teito Rapid Transit Authority under the Land Transportation Business Adjustment Law.
