TheMidōsuji Line (御堂筋線,Midōsuji-sen) is arapid transit line inOsaka, Japan, operated byOsaka Metro. Constructed underMidōsuji, a major north-south street, it is the oldest line in the Osaka subway system and the second oldest in Japan, following theTokyo Metro Ginza Line. Its official name isRapid Electric Tramway Line No. 1 (高速電気軌道第1号線), while theOsaka Municipal Transportation Bureau refers to it asOsaka City Rapid Railway Line No. 1 (大阪市高速鉄道第1号線), and inMLIT publications it is referred to asLine No. 1 (Midōsuji Line) (1号線（御堂筋線）). On line maps, stations on the Midōsuji Line are indicated with the letter "M".
North of Nakatsu it runs above ground in the median ofShin-midōsuji, an elevated freeway.
The section betweenMinoh-kayano andEsaka is owned and operated byKita-Osaka Kyuko Railway (北大阪急行電鉄,Kita Osaka Dentetsu), but is seamless to the passengers except with respect to fare calculations.
In June 2018, the Midōsuji Line is the most congested railway line in the Kansai region of Japan,[2] at its peak running at 151% capacity between Umeda and Yodoyabashi stations.

The Midōsuji Line was the first subway line in Osaka and the first government-operated subway line in Japan. Its construction was partly an effort to give work to the many unemployed people in Osaka during the early 1930s. The initial tunnel fromUmeda toShinsaibashi, as well as the Umeda depot, were constructed entirely by hand and opened in 1933 after being initially plagued by cave-ins and water leakage caused by the poor composition of the earth below northern Osaka and the equally poor engineering skills of the work crew.[3] The first cars were hauled onto the line by manpower and pack animals from theGovernment Railway tracks near Umeda.[citation needed]
Although the line only operated with single cars at first, its stations were designed from the outset to handle trains of up to eight cars. The line was gradually extended over the next few decades, completing its current length in 1987, making it the second-longest subway line in Osaka after theTanimachi Line (excluding the Kita-Osaka Kyūkō Railway extension of the Midōsuji Line).
All stations are located within Osaka Prefecture.
Since 1987, all Midōsuji Line rolling stock operated by Osaka Metro are stored and maintained at Nakamozu Depot, the first underground depot in the Osaka Metro system. The first depot for the Midōsuji Line was located near Umeda station, which was replaced by Abeno Depot in 1950, Nagai Depot in 1954 (now used mainly for maintenance-of-way vehicles), and Abiko Depot in 1960 (closed in 1987). Since 2016, it is also possible for Midōsuji Line rolling stock to access Midorigi Depot on the Yotsubashi Line viapointworks before Daikokuchō station, after heavier repairs and maintenance of all third-rail-powered Osaka Metro rolling stock were consolidated there.
Women-only cars were introduced on the line from 11 November 2002. There is one such designated car in each train (Car No. 6), the use of which is restricted all day on weekdays.
