Osaka Metro

Osaka Metro is one of three rapid transit networks based in the Kinki region and the only one based in the Osaka region. It is owned and operated by a private company known as Osaka Rapid Electric Tramway, KK. 
Originally known as the Osaka Municipal Subway, the network was operated by the Osaka Municipal Transport Bureau from its inception in 1933 to 31 March 2018, when ownership was handed over to said company; plans to privatize the system actually started in 2013 and final approval for this occurred in 2017.
A unique trait about the Osaka Metro is that it is legally classified as a tramway, despite all other metro systems in Japan being legally classified as railways. In spite of its classification as a tramway, the Osaka Metro has characteristics typical of a full-fledged metro system.
