A new line called the Naniwasuji Line is planned to be opened by 2031 and will route trains under the Naniwasuji corridor to JR Namba Station and further south. To prepare for the opening of the line, an additional two underground platforms (serving four tracks on the former Umeda Freight Line) are currently under construction on the northwest side of the station; these are tentatively slated for opening in fiscal 2023, and their numbering has yet to be made public. Once these platforms are opened, there will be a total of eight platforms serving 16 tracks. They will also enable the limited express Haruka (which currently runs on the former Umeda Freight Line that bypasses the station completely) to make a stop at Osaka Station.
