The Fukuoka High Court has confirmed its decision to reject the retrial request for Michitoshi Kumami, who was found guilty and executed for the 1992 murders of two schoolgirls in Iizuka City, Japan. In this case, Kumami's conviction relied on circumstantial evidence, including eyewitness accounts, bloodstains matching the victims’ blood type found in his vehicle, and fibers found on the victims that potentially matched those from his car. Despite his consistent claims of innocence, the Supreme Court upheld his death sentence in 2006, and he was executed in 2008.

Following the initial denial of a retrial in 2009, additional claims emerged, leading to a second retrial request in 2021 by Kumami's defense team citing new witness testimonies. The new witnesses alleged discrepancies regarding their original statements about seeing Kumami on the day of the murders, suggesting potential police coercion in their initial testimonies. However, the Fukuoka District Court dismissed these testimonies as unreliable in 2024, further affirming Kumami's conviction.

In the high court proceedings, Kumami’s lawyers requested the disclosure of investigative records, asserting that the police must have kept records relevant to the case. The prosecution provided some information to the judges but maintained that the disclosures did not support the defense's claims. The court ultimately concluded the discussions without any new compelling evidence to warrant a retrial, leaving unresolved questions about the reliability of the evidence and the judicial processes that resulted in Kumami’s conviction and execution.
