Mitsuo Terada, also known as Tsunku, has been diagnosed with Laryngeal cancer. This was announced on March 6th on the official website of the artist. Tsunku is a name you might know from the Rhythm Tengoku/Heaven series, as he has been responsible for the music in those games. In the statement, he said that he 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 the cancer 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. Tsunku has been away for a while, because the treatment has been intense. He thanked the fans and assured them that he is mentally fit and ready. He plans to continue to work.
