It has been announced today that Tamamori, Senga, and Miyata will be taking part in this year's Dream Boys, which is named Dream Boys JET.
Unlike previous years, the story has been changed to be based on Kondo Masahiko's life, and it will be about car racing.
Tamamori plays the lead, while Senga will be playing his rival.
Matchy will also have a special appearance in the stage show.
There will be 38 shows from 9/5 to 9/29 at Teigoku Theatre, but no complete schedule is up yet. It will probably show up on J-Net sometime soon.
