- While KAT-TUN were performing in the theatre production "Dream Boy", Junno sustained a serious back injury in rehearsals. He was in hospital for months and got very lonely. During his stay in hospital he became more humble and less confident in himself. Because the other KAT-TUN members didn't visit him much, he thought no one liked him. But then they came and brought gifts, and soon Junno was recovering well. He managed to overcome his back injury and return to dancing and acrobatics.

- He thinks that living together before marraige is the wrong thing to do, and that couples should show commitment.

- He admires Koichi Domoto from the KinKi Kids.
