The Chuo Subway Line

Osaka Metro’s Chuo Line runs from west to east between Yumeshima Station and Nagata Station. Beyond Nagata Station this line continues through onto the Kintetsu Keihanna Line, which runs eastward as far as Gakken Nara-Tomigaoka Station in the city of Nara. Osaka Metro and Kintetsu Railway both operate through train services on these lines, and collectively the two lines are nicknamed “Yumehanna”.

The Chuo Line is the only Osaka Metro line that connects with all of the other Osaka Metro lines. At Cosmosquare Station it also connects with the New Tram, also called the Nanko Port Town Line. Osaka Metro and Kintetsu services are not covered by the Japan Rail Pass. However, IC cards, contactless payment, ordinary tickets and several discount passes can be used on Osaka Metro, and these are listed at the end of this article.

Cosmosquare Station was the western terminus of the Chuo Line until the extension to Yumeshima Station opened on January 19, 2025. Yumeshima later hosted Expo 2025 Osaka, Kansai, Japan, which ran from April 13 to October 13, 2025.
