Tokyu

The oldest predecessor of company was the Musashi Electric Railway , opened in 1908; the railway's operations were converted into a company in 1910. Keita Got?, now known as a notable Japanese industrialist, was appointed as the CEO of the Musashi Electric Railway in 1920 and later he began a mass expansion program. The most important predecessor was first registered on September 2, 1922, as the Meguro-Kamata Electric Railway and is related to the construction of Den-en-ch?fu ; it was acquired by the Musashi Electric Railway in 1924, shortly before Musashi was renamed into the Tokyo-Yokohama Electric Railway , also known as the Toyoko, in the same year.

After Musashi/Toyoko's acquisition, the Meguro-Kamata Electric Railway initially operated as a subsidiary of Toyoko. It was not until 16 October 1939 that both Toyoko and Meguro-Kamata Electric railways were formally merged; the new company took the Toyoko name.

In 1938, Toyoko established Toyoko Eiga , possibly for competition with Ichizo Kobayashi's Toho Company. It became the Toei Company in 1951.

Toyoko took its current name on 1 May 1942, after the Japanese government forced the company to acquire the Odawara Express Railway and the Keihin Electric Railway in 1943 to support Japan's efforts in World War II. In 1944 it also acquired the Keio Teito Electric Railway . In 1948, Tokyu divested the forced-acquired companies, and the divested companies are now known as Odakyu Electric Railway, Keikyu Corporation, and Keio Corporation respectively. The 1943–1948 era of Tokyu was colloquially known as Dai-Tokyu .
