It's not like the creepy niche Japanese stuff even gets released in the US.
Anyhow back to Sony Japan Studio. I think last gen they had basically 4 quality teams putting out games you'd actually want to play: Team Siren (Siren 1, 2), Team Ico (Ico, SoTC), Ape Escape Team (AE 2, 3), PD (Gran Turismo 3, 4).
At least 3 of those teams are still alive and making games, even if they are slooooooooowly making them. Real shame that they gave up on Ape Escape though. It seems like a huge missed opportunity to not have done a real full length Ape Escape platformer as the MOVE flagship game where you swing around your net catching monkeys while platforming and exploring and fighting bosses, much in the way AE1 was the flagship for Analog control.
