What? What renaissance are you referring to?
The only Japanese game dev “renaissance”, which is a loaded presumptuous word, was around 2016 when Persona 5, Nier Automata, Dark Souls 3 (and slightly earlier Bloodborne), BOTW, Yakuza Kiwami, MGSV Ground Zeroes, were beloved and specifically after a few years where ignorant morons were falsely ignorantly claiming that Japanese game design was either “dead” or in the shadows. The ignorant sentiment seems to be based on biased trivialities like the idea that Japan-origin studios didn’t have something like Skyrim in the west, or the fact that Binary Domain didn’t succeed well as a Gears of War copy, or that Wii U wasn’t a big success, or maybe (most rationally) the fact that PS3 was the only one that “lost” to Xbox, so to speak.
There were very few Japanese studios under Sony SIE, but that was always true and nothing changed.
