Kingdom Hearts II Final Mix is a Japan-exclusive reissue of Kingdom Hearts II that uses primarily English voice acting with Japanese text, subtitles and controls, as well as bonus content.
Kingdom Hearts II Final Mix was rumored in middle-late 2006. Though Nomura did not confirm its development, he stated that if a Final Mix version were to be created for other countries, he would use a "trump card".
In September 2006, Kingdom Hearts II Final Mix was finally announced, and released on March 29, 2007, hitting stores all across Japan. The director of the Kingdom Hearts series, Tetsuya Nomura, has quoted, "The Final Mix games are only Japanese exclusives. In due time I may release a Final Mix into other countries, but Kingdom Hearts Final Mix and Kingdom Hearts II Final Mix are not my choice."
On October 14th, 2013 at D23 Expo it was announced that Kingdom Hearts HD 2.5 ReMIX will contain Kingdom Hearts II Final Mix along with Kingdom Hearts Birth by Sleep Final Mix and Kingdom Hearts Re:coded as HD cinematics and is slated for release late 2014.
Initial previews and announcements
Scans of magazine articles and preview videos appeared on numerous websites in the weeks leading up to the game's release. They included additional scenes involving the three mysterious armored knights at the end of the Kingdom Hearts II secret ending. Later screenshots showed one of these three knights in combat with Sora, Donald, and Goofy. The being serves as a secret boss with incredible power and an enormous amount of HP, much like the Enigmatic Man from Kingdom Hearts Final Mix. The preview videos also showed that battling Roxas would be possible as opposed to the cutscene in the original game. Square also revealed that data replicas of each member of Organization XIII could be challenged in a secret area at Hollow Bastion and fought independently of the storyline.
Voice-acting on Kingdom Hearts II Final Mix was announced to be mostly in English, with Japanese subtitles, like Kingdom Hearts Final Mix, but the new scenes used Japanese voice-acting when viewed in Theater Mode and were voiceless in-game with Japanese subtitles. This is most likely due to the new scenes featuring Organization XIII members from Kingdom Hearts: Chain of Memories, whom did not yet have English voice actors.
- A new difficulty mode called Critical Mode.
- Textures redone with a better definition. 
- A new Drive Form called "Limit Form" has abilities from Kingdom Hearts and Kingdom Hearts Final Mix, and also bears resemblance to Sora's outfit from the original game.
- A new mini-game called Puzzle, which unlocks special items.
- Many Heartless received palette swaps.

- New cutscenes based on the Kingdom Hearts II novels were added; some involve Roxas, including scenes of him conversing with Axel in Twilight Town while wearing the Organization's signature black coat. There are also additional scenes of Roxas and Riku, including shots of their second battle, where Riku takes on the form of Ansem, Seeker of Darkness, Naminé leaving with Axel, Riku and Sora talking before they battle 2nd Armored Xemnas, Xigbar and Zexion talking about Xemnas, and the Organization discussing their plans and commenting on incidents like Axel's death.
- Zexion's weapon is revealed - a large book called a "Lexicon", which he can use to trap his enemies in an alternate reality.
- Members of Organization XIII that were eliminated in Kingdom Hearts: Chain of Memories can be found and fought in the various worlds of Kingdom Hearts II Final Mix. They each use different fighting tactics from the ones they employed in Kingdom Hearts: Chain of Memories. They include Vexen, Larxene, Marluxia, Lexaeus, and Zexion.
- An area of Radiant Garden, called the Cavern of Remembrance, can be accessed. It houses a series of battle simulations with each member of Organization XIII. This is a separate feature from the secret battles with the Kingdom Hearts: Chain of Memories Organization members in that the simulation allows the player to repeat any battle with an Organization member as often as they like. The simulation features highly powered-up Organization members, similar to the level bonuses offered to enemies in the Hades Paradox Cup.
- Battles with the Mushroom XIII can be fought.
- A "Theater Mode" - menu where previously viewed cutscenes can be watched again with either English or Japanese voices by pressing L2 and R2.
- Secret features can be accessed in Kingdom Hearts II Final Mix by clearing Kingdom Hearts Re:Chain of Memories, and vice versa.
