Naruto Shippūden: Ultimate Ninja 4

is a Japanese-only game and the fourth installment in the Narutimate Hero (Ultimate Ninja) series. It is also the second Naruto game based on the Naruto: Shippūden anime series, which is based on the second part of the manga. The game was released on April 5, 2007 in Japan, and is planned to come to America in early 2009.

The game was first seen in issue #2006-52 of Weekly Shonen Jump along with information about the Naruto: Shippūden anime and related merchandise.

In addition to elements established in previous Narutimate Hero games, Narutimate Accel offers several new twists to combat. When two opponents clash, they will begin a series of high-speed attacks, appearing as a pair of blurs dueling across the stage. The winner is determined by a game of Rock, Paper, Scissors. There is also the inclusion of the "Awakening Ougi." When certain conditions are met, a character may trigger an Awakening Ougi. These techniques are more powerful than the standard Ougis and, as the name implies, "awakens" a character's powers (i.e. Naruto's tailed-fox form with overpowering red chakra).
