The Japanese box cover for Kingdom Hearts III has been revealed on Twitter thanks to @soranchu0309, which shows that game requires at least 40GB or disk space to install Kingdom Hearts III on the PlayStation 4.
Middleware software including SpeedTree for vegitation modeling and rendering, IKINEMA for motion capture and realistic body animation, and Mercuna for 3D navigation are also listed on the back of the box as being some of the technology utilized in Kingdom Hearts III.
Audrey (@aitaikimochii), CEO and founder of Aitai Japan, has translated a portion of the box's tagline that references the opening theme songs from Kingdom Hearts, Kingdom Hearts II, and Kingdom Hearts III by Utada Hikaru:
A heart that harbors LIGHT
Becomes PASSION
That fulfills an OATH
