Ryutaro starts off just like the rest as a junior. Then he got into J J Express together with his group mates Yuto, Yamada, Chinen, Inoo, Takaki and Daiki. Even his younger brother got into the same group. From there he does many of the senior's concerts.
Finally in the late 2007, Hey Say Jump debut. And he got to be on the stage as himself and be proud of it. There are more concerts to come for them so Ryutaro-chan "All the best"
