The KAI YOSHIHIRO Billboard Live Series, popular every year, is in its 12th year and will once again span a total of nine days across three cities—Tokyo, Yokohama, and Osaka. Blending decades of experience and mature expressive power with a creativity that lightly transcends established notions, he continues to captivate listeners to this day. In 2025, commemorating the Kai Band’s 50th anniversary, the Nippon Budokan concert was a resounding success, and a Tokyo Toyosu PIT show was added—something still fresh in memory. 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.
