Hatsune Miku: Project Mirai DX is a rhythm game and the sequel to Hatsune Miku and Future Stars: Project Mirai. The game is also a spin-off of the Hatsune Miku: Project DIVA series of Vocaloid rhythm games. Like the original, the game primarily makes use of Vocaloids, a series of singing synthesizer software and the songs created using these vocaloids, most notably the virtual-diva Vocaloid Hatsune Miku. While Project Mirai only had button controls, Project Mirai 2 adds the use of touch screen controls where players tap the bottom screen. An increased sense of speed and additional gimmicks have also been added.

The "PuyoPuyo 39" mini-game can be played by two people through a local wireless connection.
