The ever-popular Kai Yoshihiro Billboard Live Series, now in its 12th year, will once again span nine days across three cities—Tokyo, Yokohama, and Osaka. He, who has long built up experience and matured expressive power, blends that with a creativity that lightly transcends conventional notions, and continues to captivate listeners to this day. In 2025, marking the Kai Band’s 50th anniversary, the Budokan performance was a huge success, and the Tokyo Toyosu PIT show was added—a memory that remains fresh. This is an exquisite acoustic show where you can directly feel the heart-stirring, fiery sound and the power of Kai Yoshihiro’s own voice, to the fullest.
