Sony announced that it’s ending PSP software sales on the PSP’s PlayStation Store as well as the UMD Passport service on March 31, 2016 in Japan, Inside Games reports. Previously purchased content will be still available and can be downloaded again.
According to the official release and pointed out by Twitter user Mazyx, PSP owners in Japan can still buy PSP content through the Vita, PS3, PC or mobile devices and then transfer them to their PlayStation Portables.
This winding down isn’t totally unexpected, since Sony ceased shipping new PSP units last year in Japan.
