TOKYO (AP) — Juro Kara, who helped shape Japan’s postwar avant-garde theater, defiantly yet playfully transforming the essence of Kabuki aesthetics into modern storytelling, has died. He was 84.

The playwright, director and troupe leader died late Saturday from a blood clot in the brain after he collapsed at home and was rushed to a Tokyo hospital on May 1, his theater group Karagumi said in a statement on Sunday.

Kara, whose real name was Yoshihide Otsuru, rose to stardom in the so-called Japanese underground movement of the 1960s known as “un-gura,” characterized by a kitsch rebellious style also found in his contemporaries Shuji Terayama and Tadashi Suzuki.

Kara’s colorful shows, often in makeshift tents evocative of a traveling circus, rejected the established theatrical modes then dominating modernizing Japan that were mostly Western, middle class and well-behaved.
