Murai was mortally wounded when an ethnic Korean man named Hiroyuki Jo (徐裕行 Jo Hiroyuki), a member of the Yamaguchi-gumi (the largest organized crime Yakuza group in Japan), stabbed Murai repeatedly, in the presence of 10 police officers and about a hundred reporters recording the events and broadcasting them live. As Murai lay dying in the street, he allegedly uttered "Jews got me".
His attacker didn't attempt to flee and was peacefully arrested on the spot. Murai died in an ambulance.
