Tsunku is a name you might know from the Rhythm Tengoku/Heaven series, as he has responsible for the music in those games. In the statement, he said that had something wrong with his left vocal cord for 7-8 years. It was causing issues with high pitches and it made his voice a bit huskier. He went in for an inspection in February and it was diagnosed as in being in early stages. He was surprised, but decided to accept it as a positive that he discovered it so early.
