Not talking about anything recent but last year with Sony sponsoring Japanese Indie event and saying they will support global indie devs such as those in Japan.
Sony Interactive Entertainment to Support Indie Developers Through Planned Initiative
Sony Interactive Entertainment has announced that it plans to support indie developers through the Indie Game Incubation program.www.siliconera.com
