History
Tamade Station opened on 31 May 1958 as the southern terminus of Osaka's Route 3, today the Yotsubashi Line of Osaka Metro, when the line was extended from Kishinosato. On 1 June 1971 an experimental automatic ticket gate was installed at the south concourse — the very first automatic gates on the Osaka municipal subway. The station ceased to be a terminus on 9 November 1972 when the line was extended on to Suminoe-Kōen, with a small relocation of the station box accompanying the work. The municipal operator was corporatised on 1 April 2018 and the station passed to Osaka Metro.

Notes
Tamade was Japan's first station to use centrifugally-cast steel pipes as its centre platform columns — slender, high-strength supports that subsequently replaced the much bulkier reinforced-concrete columns common in earlier subway construction.
