The Tokyu Corporation (東急株式会社, Tōkyū kabushiki-gaisha), a contraction of and formerly Tōkyō Kyūkō Dentetsu kabushiki gaisha (東京急行電鉄株式会社, "Tokyo Express Electric Railway Share Company") until 2 September 2019, is a Japanese keiretsu or conglomerate headquartered in Shibuya, Tokyo.

While a multinational corporation, its main operation is the Tokyu Railways Company, Ltd.[1] (ja:東急電鉄株式会社, Tōkyū Dentetsu kabushiki gaisha), a wholly-owned subsidiary operating railways in the Greater Tokyo Area.

Keita Gotō, now a notable Japanese industrialist, was appointed as the CEO in 1920 and he began a major expansion program.

Toyoko took its current name on 1 May 1942, after the Japanese government compelled the company to acquire the Odawara Express Railway and the Keihin Electric Railway in 1943 to support Japan's efforts in Pacific War of World War II.

The Tokyu Group also owns two smaller railroad companies, Ueda Kōtsū and Izukyū Corporation; several bus companies; and a major upscale department store chain, the Tokyu Department Store operating in Japan and the MBK Center in Bangkok, Thailand.
