The new platform is in the "Umekita 2nd phase" redevelopment area on the station's north side. It is connected to the newly constructed west exit ticket gates on Osaka Station's first floor via a dedicated passageway and to the Grand Front Osaka commercial complex via an underground corridor—one of the seven new ticket gates has a tunnel-style facial recognition system. If a photo of the passenger's face is registered in advance, the passenger can go through the gate without passing an IC money card over a reader. The system is still experimental, and JR West is recruiting monitors, hoping to be fully operational by the Osaka Kansai Expo in 2025. The underground platform will be used by the limited express trains "Haruka" and "Kuroshio," which previously did not stop at Osaka Station. As a result, the travel time between Osaka Station and Kansai International Airport will be reduced by 20 to 47 minutes, and the travel time between Osaka and Wakayama stations will be reduced by 33 to 57 minutes.
