Square Enix updated Tokyo RPG Factory website in Japan with a new main visual, illustration but nothing more. On this website you can find the information and the direct link to the Ikenie to Yuki no Setsuna (PlayStation 4, Vita, Nintendo Switch).
Tokyo RPG Factory is 100% owned by the Square Enix Holding. Their first game was the Ikenie to Yuki no Setsuna / I Am Setsuna (Project Setsuna) which released on February 18, 2016 first in Japan on PS4 and Vita and on March 3, 2017 re-released of the Nintendo Switch.
Maybe a new game is on the way or maybe just a little design update for the website, it is unknown. You can find the old picture in the gallery and the new one too as a screenshot from the pages. Stay tuned for more information.
