Kingdom Hearts Birth by Sleep Final Mix is a Japan-exclusive reissue of Kingdom Hearts Birth by Sleep for the Sony Playstation Portable (PSP). Most plot and gameplay elements are the same, and the game also includes the features added to the North American and European versions of the game. Much like its predecessors, Kingdom Hearts Final Mix and Kingdom Hearts II Final Mix, Kingdom Hearts Birth by Sleep Final Mix combines English voice-overs with Japanese text and controls.
Kingdom Hearts Birth by Sleep Final Mix was officially confirmed for release on September 14, 2010, a week after the North American release of Kingdom Hearts Birth by Sleep. It was first announced in the September 13 issue of Weekly Shōnen Jump magazine. The game was released January 20, 2011 in Japan exclusively.
On October 14, 2013 at D23 Expo it was announced that Kingdom Hearts HD 2.5 ReMIX will contain Kingdom Hearts 2 Final Mix along with Kingdom Hearts Birth By Sleep Final Mix and Kingdom Hearts Recoded as HD cinematics which were released in 2014.
Several new changes and features have been made to expand on the original Kingdom Hearts Birth by Sleep. Many of the changes were introduced in the international releases of the game, but several are unique to this release.
- Critical Mode has been added as a Difficulty Level.
- All Unversed have been given new color schemes. For example, the Flood is now purple instead of blue.
- The Sticker Album and its related quest have been added, though several of the rewards have been modified from the international release.
- The Rhythm Mixer Command Style has been added. It is musical-themed, and requires the player to press button prompts for the finisher.
- The Unison Rush, Voltage Stack, Illusion commands have been added.
- Characters in certain cutscenes, including ones on the Destiny Islands with Sora and Riku, are given higher quality facial animations.
- The Skull Board has been added as a Command Board.
- Pete has been added as a Dimension Link.
- The Castle Circuit track has been added to Rumble Racing.
- The "Destiny Islands" song has been added to Ice Cream Beat.
- Vanitas Remnant gives the Void Gear Keyblade.
- Young Xehanort appears as a boss, and gives the No Name Keyblade.
- Armor of the Master, Monstro, and No Heart appear as bosses of the three new Mirage Arena battles, "Mentor of Light", "Monster of the Deep", and "Foresight unto Darkness", respectively.
- The "Monster of the Deep" battle is made up of a timed stage where the player can attack Monstro directly, and an acid-filled stage within Monstro's belly where the player is sent once the two minutes run out. The player must defeat the Unversed within Monstro to escape and try to damage Monstro further.
- Beating the "Foresight unto Darkness" Mirage Arena match grants the player a new Keychain, the Crown Unlimit Keyblade.
- A new secret scene named "A fragmentary passage" has been introduced, in contrast to the secret movies seen in previous games. In the "Secret Episode", the player controls Aqua through the Realm of Darkness, rather than watching the Blank Points secret movie from the NA release.
- This is also the only part of the game where new cutscenes were created, with three new cutscenes, which included new dialogue provided by Aqua's Japanese voice actress Megumi Toyoguchi.

- Weekly Famitsu Vol. 1144 (11/18/2010); Tetsuya Nomura: "In the Secret Episode, you'll actually be able to control characters. I think you'll be able to relish a different kind of surprise to simply watching a movie."
