since the end of last week, Ozeki Mai had problems with her throat and got treatment. After a medical examination once more, she was diagnosed with vocal cord nodules problems and won't be allowed to sing this weekend. She won't be allowed to sing, but she will appear and perform at these events : release event for Country Girls on 8/14, the Country Girls Live tour concert in Hiroshima on 8/14, and the H!P concert in Hiroshima on 8/15.
