Kudo-kai leader sentenced to life imprisonment; first trial death sentence revoked by Fukuoka High Court. Satoru Nomura (77), the organization's leader and president, was sentenced to death in the first trial after being charged with murder and other crimes in four cases.

Concessions such as port construction work are said to be behind the incident. The three attacks, in which a former police officer, a nurse, and a dentist were attacked, are facing charges including attempted organized murder, which violates Organized Crime Punishment Act.
