This year's 17th issue of Shueisha's Weekly Shonen Jump magazine is annoucing on Monday that Naruto manga creator Masashi Kishimoto is personally conceiving the all-new story and designing the characters for the newest Naruto the Movie: Road to Ninja. The film, which marks the 10th anniversary of the Naruto anime franchise, will open throughout Japan on July 28.
The magazine had already announced that the sixth Naruto Shippūden film and ninth Naruto film overall will open this summer. Naruto Shippūden: Blood Prison, the fifth Naruto Shippūden film, opened last July. Viz Media released the second Naruto Shippūden film, Naruto Shippuden the Movie: Bonds, in American theaters last October.
