Hey! Say! JUMP are getting a musical this year and it is being aimed to break a Guinness World Record for largest cast. the cast will be about 100 members large and will comprise of Hey! Say! JUMP, rotating members of Kis-My-Ft2, Sexy Zone, A.B.C-Z, Domoto Koichi, Takizawa Hideaki, Kamenashi Kazuya and the Juniors.
The musical is scheduled for November and December this year at the Tokyo Imperial Theater. And Johnny Kitagawa has plans to eventually bring the musical overseas but for now wants to concentrate on its production in Japan.

For some time I had wondered if HSJ would get a musical eventually. For some reason it just felt like they would be the next group to get a regular musical to do, mostly in part because it would give some of the members that do not get a lot of the spotlight a chance to shine and do something. Of course it does not look like that will happen, or at least not with this initial production. Though if the musical sticks around for a while I can see it becoming something like Dreamboys and it will rotate what members of the group perform each year. But only time will tell what will happen with this.
I am not sure what to think about a Johnny's musical being brought overseas. I am not sure how something like a Johnny's musical would do in a non-Japanese market, but if they do bring such a large and varied cast they do have a good chance for success if only from fans just wanting to see their favorites live no matter what.
