Hatsune Miku: Project DIVA (video game)

Hatsune Miku: Project DIVA (初音ミク -Project DIVA-) is a 2009 rhythm game created by Sega and Crypton Future Media for the PlayStation Portable (PSP). The game was first released on July 2, 2009 in Japan with no international release. The game primarily makes use of Vocaloids, a series of singing synthesizer software, and the songs created using these Vocaloids, most notably Hatsune Miku. The game is the first video game to utilize the Vocaloid software developed by the Yamaha Corporation.

In addition, Sega has released Hatsune Miku: Project DIVA Dreamy Theater, a downloadable game on the PlayStation Network (PSN) for the PlayStation 3 (PS3). It allows players to play Project DIVA on the PS3 with updated visuals though it requires the PSP to be plugged into the PS3 via USB cable.
