This music festival is not just an entertainment event; it is an attempt to establish a new culture and community in the Kansai region. The “showcase” held at the Expo in May was enjoyed by a wide range of people, from high school students on their way home from school to families with small children. We believe that the music of virtual artists has the power to connect people across ages and backgrounds. Kansai has a long-standing culture that values laughter and entertainment. We hope to carry on this tradition while also integrating it with the latest digital technology to create a new culture that brings joy and excitement to many people.
