Casiopea, continuing to lead Japan's fusion scene, will embark on a spring three-city Billboard Live Tour. Since their formation in 1977, they have released numerous hits such as ASAYAKE and DOMINO LINE, drawing attention not only in Japan but also from overseas. In 2025, keyboardist Jun Abe joined, and with this new start the band's name adopted its original spelling CASIOPEA. In May of that year, they held their first show with the new lineup at Billboard Live here, and in August they released the album 'TRUE BLUE', which includes songs performed on that tour. About a year into the start of the fifth era, enjoy the virtuoso performances that transcend eras and nations in an intimate club setting.
