The Osaka Municipal Subway (大阪市営地下鉄 Ōsaka-shiei chikatetsu) is the rapid transit network in the Osaka Metropolitan Area of Japan, operated by the Osaka Municipal Transportation Bureau. It serves the city of Osaka and the adjacent municipalities of Higashiosaka, Kadoma, Moriguchi, Sakai, Suita, and Yao. The subway forms an integral part of the extensive mass transit system of Greater Osaka (part of the Kansai region), having 123 out of the 1,108 rail stations (2007) in the Osaka-Kobe-Kyoto region. In 2010, the greater Osaka region had 13 million rail passengers daily (see Transport in Keihanshin) of which the Osaka subway accounts for 2.29 million.
The Osaka Municipal Subway holds the distinction of being the only subway system in Japan to be legally classified as a tramway, whereas all other subway systems in Japan are legally classified as railways. Despite this, the Osaka Municipal Subway has characteristics typical of that of a full-fledged metro system.
A proposal to privatize the Osaka subway was sent to the city government in February 2013, is still under consideration. The privatization would bring private investors to Osaka and could help revive Osaka's economy. The subway could be valued at over 600 billion yen.
The Osaka Municipal Subway's first service, the Midōsuji Line from Umeda to Shinsaibashi, opened in 1933. As a north-south trunk route, it is the oldest and busiest line in the whole subway network. Both it and the main east-west route, the Chūō Line, were later extended to the north and east, respectively. These extensions have private ownership, but both the city government and the private operators run their own set of trains through between the two sections.
All but one of the remaining lines of the network, including the Yotsubashi Line, Tanimachi Line, and Sennichimae Line, are completely independent lines with no through services. The lone exception is the Sakaisuji Line, which operates through trains to existing Hankyu Railway lines and is the only line to operate through services to existing railway lines that are not isolated from the national rail network (which is the case with the Midōsuji and Chūō Lines).
Nearly all stations have an letter number combination, the letter identifying the line served by the station and the number indicating the relative location of the station on the line. For example, Higobashi Station on the Yotsubashi Line is also known as Y12. This combination is heard in bilingual Japanese-English automated next-station announcements on board all trains, which also provide information on local businesses near the station. Only Hankyu stations served by the Sakaisuji Line do not follow this convention.
Currently, there are eight subway lines, operating on 129.9 kilometers (80.7 mi) and serving 123 stations; there is also a 7.9-kilometer (4.9 mi) long, 10 station automated people mover line operated by the Osaka Municipal Transportation Bureau:

Planned line and extensions
In addition, there are four line extensions and one new line that are planned. However, on August 28, 2014, the Osaka Municipal Transportation Bureau met about creating the extensions of the later four of the five lines listed below, and have stated considering the current cost of the new extensions and the possibility of privatization, the government has also thought creating light rail transit or bus rapid transit instead.

Technology and rolling stock
Osaka Municipal Subway rolling stock use two types of propulsion systems. The vast majority of lines use trains with conventional electric motors, but the two newest lines, the Nagahori Tsurumi-ryokuchi Line and Imazatosuji Line, use linear motor-powered trains, which allow them to use smaller trains and tunnels, reducing construction costs. These two lines have half-height automatic platform gates installed at all station platforms, as does the Sennichimae Line.
Also, unlike other rapid transit networks in Japan, most Osaka subway lines use a third rail electrification system for trains. Only three lines use overhead catenary: the Sakaisuji Line, to accommodate through services on Hankyu trackage; and the linear-motor Nagahori Tsurumi-ryokuchi and Imazatosuji Lines. Also unusually, all lines use standard gauge; there are no narrow gauge sections of track due to the network being almost entirely self-enclosed.

The Osaka Municipal Subway charges five types of fares for single rides, based on the distance traveled in each journey. Some discount fares exist.

On April 8, 1970, a gas explosion occurred during the construction of the Tanimachi Line at Tenjimbashisuji Rokuchōme Station, killing 79 people and injuring 420. The gas leaked out from a detached joint and filled the tunnel and exploded, creating a fire pillar of over 10 meters and destroyed 495 houses and buildings.
