WWE issued the following statement on his passing:
WWE is saddened to learn of the passing of Eiji Ezaki, better known to fans around the world as Hayabusa, at the age of 47.
An innovative high-flyer who helped inspire a generation of Superstars, the mysterious, masked Hayabusa was known for throwing caution to the wind. Ezaki created daring moves like the Phoenix Splash, which to this day can be seen in the repertoire of daredevil competitors, including former WWE World Heavyweight Champion Seth Rollins. A major star in Japan in the mid to late â€™90s, Hayabusa competed in one major American match, teaming with Jinsei Shinzaki (known as Hakushi in WWE) in a losing effort against Sabu & Rob Van Dam at ECWâ€™s Heat Wave 1998 event. Although his career was cut short by injury in 2001, Ezaki never strayed far from the industry, where he continued to impart his knowledge.
