C30 Gakken Nara-Tomigaoka The Chūō Line (大阪市営地下鉄中央線 Ōsaka-shiei-chikatetsu Chūō-sen) is one of the lines of Osaka Municipal Subway, the rapid transit system in Osaka City, Japan.
The line runs east-westerly under Chūō Avenue (中央大通 Chūō Ōdōri).
Together with the through operation to the Kintetsu Keihanna Line, the two lines have a unified nickname "Yumehanna" (ゆめはんな).
On July 1, 2005, Osaka City bought the Technoport Line (テクノポート線) from Cosmosquare to Osakakō of its subsidiary Osaka Port Transport System Co., Ltd. (大阪港トランスポートシステム), reducing fare to increase traffic. The section became a part of the Chūō Line, however is still owned by OTS.
