This may be just rumors flying around, but I heard that there was going to be a Naruto Musical to be released in Japan. It is basically a theatrical adaptation of the Naruto series using an origin story accompanied by a muscial score. As funny as the idea may sound, I was really interested in seeing a video of it, but my searches were fruitless. Some of you may have already seen the Bleach Rock Musical (Youtube links: part 1 part 2), it should give you a good idea of what a Naruto musical may be like. It would be really cool to see how they handle stuff like Naruto’s Kage Bunshin or Sasuke’s Chidori jutsus.

I’m still trying to find more information on the Naruto Musical. But so far the only source is this entry from Anime News Service:
12-17-05 (5:05PM EST)—- Naruto To Become Theatrical Play
The group MA (Musical Academy) will adapt the story of Kishimoto Masashi’s Naruto to a theatrical stage play in Japan. Princess Tenko (Princess Tenko and the Guardians of Magic) is heading up the project. Serialized in “Weekly Shonen Jump”, the 30 existing volumes of manga has sold 59 million copies. An original story will be used in the play. Tomoyuki Yara and Jun Akiyama will star. The debut performance will be held in Gotanda U-Port Kan’i Hoken Hall on May 4 next year. A show in Osaka is also planned for the 19th.

Also found this little musical number, which I found hilarious
