The is a rapid transit electric multiple unit (EMU) train type operated by Osaka Municipal Subway on the Nagahori Tsurumi-ryokuchi Line in Japan.[1]

All 25 70 series trains are scheduled to undergo major refurbishment, with set 13 the first refurbished set to re-enter service on March 4, 2011. The refurbishment will include the fitting of new linear motor traction systems, a new 3-colour LED display system above passenger doors, new LCD passenger information monitors, lower hand grips, a yellow line printed on passenger doors and new train car number indicators on the exterior similar to those seen on the 30000 series and the refurbished 25 series trains.
