Isamu Osuka, a renowned Butoh artist and founder of the dance ensemble 'Byakko-sha', passed away on February 27 at the age of 80 due to aspiration pneumonia. His funeral was held privately with close family members, with his wife, fellow dancer Sanae Hiruta, serving as the chief mourner. Osuka’s contribution to the world of Butoh was significant, especially as he was a central figure in the influential group 'Dairakudakan', founded by Akaji Maro in 1972, before establishing 'Byakko-sha' in 1980.

Born in Hiroshima, Osuka's talent and innovation in Butoh helped shape the genre alongside other notable groups, including 'Sankai Juku', led by the late Ushio Amagatsu. 'Byakko-sha' was known for its dynamic performances and often took the stage internationally, representing the essence of Butoh with their unique aesthetic. The group was active until its disbandment in 1994, leaving a legacy in modern dance.

Among his notable works is 'Hibari to Nejaka', which showcases his signature style that blends movement, theater, and the exploration of human experience. Osuka’s death marks a significant loss for the Butoh community and the performing arts in Japan, as he was a key figure in promoting and evolving this Japanese dance form on both national and international stages.
