Via Google Translate:
“I retired from SQUARE ENIX at the end of April 2021 because I would like to contact the media and users. I can’t talk about the reason now, but I hope I can talk about it when the time comes. As for future activities, I’m 55 years old, so I may retire.”
Yuji Naka led development on Nights into Dreams, Phantasy Star Online, Puyo Pop Fever, and others. He directed Balan Wonderland after joining Square Enix in January 2018. It was his first collaboration with Naoto Oshima, co-creator of Sonic. It launched in March this year. It has a mixed rating on Steam.
