Get out of the ticket gate that is located near the Osaka-umeda end of the platform.

Leave the station and walk toward the left. (Walk across the railroad crossing when you get out of the ticket gate on the platform for Kyoto.)

Walk through the sidewalk and go over the crosswalk toward the right. Then you will see Nishinakajima-Minamigata Station of the Subway Midosuji Line immediately on your right.
