For reference, his birthplace is in Saitama, as shown in an interview here: https://web.archive.org/web/20210926002053/https://kiki-voice.jp/newcolor/705

While his agent profile lists it as Okinawa, as he states in the interview, he considers that place his home since he grew up there. Edit: Just for reference, "出生地" (shusshouchi) does mean birthplace, but in this case, his agent profile has misapplied it. "出身地" (shusshinchi) can mean birthplace or where someone grew up.
