Osaka Municipal Subway

Historical Background

Osaka is the main city of Japan’s second largest metropolitan area Keihanshin. With a huge population and consequently high volume of commercial activity, this city and surrounding areas constitute a major hub of Japan.

Easy to understand in such a big region, managing traffic was always a concern for the local government. Again, the construction was necessary to provide a means of employment to the unemployed workforce of the city. In1933, between Umeda and Shinsaibashi stations, the first line of Osaka Municipal Subway, Midōsuji Line was started operation.

Construction of the further lines was stopped due to the World War II and began again after ceasing of war. Midōsuji Line achieved its current length in 1987. It is, at this moment, the second longest metro line in the city of Osaka.

The Yotsubashi Line started operation in 1942 between Daikokuchō and Hanazonochō. It achieved its current length in 1972. In 1961 an elevated portion of Chūō Line between Ōsakakō and Bentenchō was opened. After many extensions, the current track length was achieved in 1985.

Tanimachi Line is operational since 1967. Initially, revenue service began between Higashi-Umeda and Tanimachi Yonchōme. In 1983, the last extension took place from Moriguchi to Dainichi.

In 1969, another two lines, namely, Sennichimae Line and Sakaisuji Line entered revenue service. In 1981, Sennichimae Line achieved its current length from Nodahanshin to Minami-Tatsumi. The track for Sakaisuji Line, from Tenjimbashisuji Rokuchōme to Tengachaya was fully opened in 1993. Nagahori Tsurumi-ryokuchi Line, between Kyōbashi and Tsurumi-ryokuchi was opened in 1990. In 1997, it was further extended to both sides. The last line, Imazatosuji Line started full service in 2006, connecting Itakano to Imazato. In 1981, the people mover line, namely, Nankō Port Town Line was opened between Nakafuto and Suminoekōen. The last extension in this line took place in 1997 from Nakafuto to Cosmosquare.
