Voodoo Murders
On May 29, 2011, Hirai was involved in a backstage fight with TARU, which led to Hirai suffering a stroke after competing in a match. He would eventually undergo successful surgery. Following the incident, all Japanese members of the Voodoo Murders (TARU, Minoru, KONO, and MAZADA) were suspended indefinitely from All Japan, the Voodoo Murders stable was disbanded and Keiji Mutoh resigned as the president of the promotion. As of February 2013, Hirai was still recovering from the incident, but was looking to eventually return to professional wrestling.
