Kingdom Hearts IV is being developed inside Square Enix’s Creative Studio 1, according to comments from Naoki Hamaguchi. The confirmation places the next Kingdom Hearts game in the same internal studio that is also building Final Fantasy VII Revelation.
What Naoki Hamaguchi said about Creative Studio 1
In a Deadline interview published on September 10, Hamaguchi discussed Square Enix’s 2027 plans and identified the studio responsible for both projects.
“And both are being developed in my own studio, Creative Studio 1. So yeah, I’m really pumped up now for that. That’s really all on my watch now, so I’m going to be the guy who’s pushing all that forward.”
The statement is a direct confirmation of the games’ shared organizational home. It does not merely say that staff exchange ideas across Square Enix; Hamaguchi explicitly says both are being produced in one studio.
Two major projects under one studio
Hamaguchi described the two releases as work under his oversight rather than unrelated projects elsewhere in the company. After identifying Creative Studio 1, he said the two games were “all on my watch” and that he would be “the guy who’s pushing all that forward.”
For Kingdom Hearts IV, the concrete update is the studio assignment. GamerHeadlines’ earlier Kingdom Hearts IV coverage remains separate from this production detail.
Hamaguchi framed both games as important to Square Enix’s next year. He said company president Takashi Kiryu has called 2027 a “big fight back” and described Kingdom Hearts IV and Final Fantasy VII Revelation as “massive titles” that will help drive it. His comments connect Creative Studio 1’s workload directly to that broader company push.
How far the studio confirmation goes
The new evidence should be read narrowly. Hamaguchi confirms Creative Studio 1’s role, the shared-studio arrangement, and his oversight. A shared studio does not by itself establish how staff or resources are divided between the two productions.
Hamaguchi’s wording does, however, establish his oversight. After naming the two games, he said the work was “all on my watch” and that he would be “the guy who’s pushing all that forward.” That describes his responsibility across the two named projects without supplying a project-by-project credit list.
Why the studio detail matters
Creative Studio 1’s work on both Kingdom Hearts IV and Final Fantasy VII Revelation gives a clearer picture of Square Enix’s development structure.
It also provides a better frame for other discussions around the game, including recent Kingdom Hearts IV speculation. Hamaguchi’s interview confirms the studio arrangement; it does not validate theories about the story, characters, or links to other Square Enix projects.
The concrete takeaway from Hamaguchi’s interview is that Creative Studio 1 is producing Kingdom Hearts IV and Final Fantasy VII Revelation at the same time, with Hamaguchi overseeing the work.
