The Nintendo 3DS adventure will be available from July 20 across Europe and July 31 in North America.
Kingdom Hearts: Dream Drop Distance will follow lead characters Sora and Riku as they travel into the Sleeping Worlds to become true Keyblade masters.
Claiming that its quality is "at the level of a console game", Nomura insisted that the 3DS release will feature the "flashiest motion of the series thus far".
It will feature new gameplay elements, including the ability to recruit more than 50 different types of dream eater spirits that can join Sora and Riku in battle.
Players will also travel to new worlds based on Disney's The Hunchback of Notre Dame and Tron: Legacy.
Kingdom Hearts: Dream Drop Distance will be the seventh game in the series and follows PSP title Kingdom Hearts: Birth By Sleep, which was released last year.
