In a notable case that has caught public attention, Kohei Iizuka, a 36-year-old unemployed man, has appealed against his life sentence for the murder of Hiroshi Shinjo, his probation officer, in Otsu City in 2024. Initially convicted and sentenced by the Otsu District Court, the defendant's appeal against the judgment was filed on the 6th of this month, signifying a rejection of the court's decision to impose a harsh sentence that aligned with the prosecution’s demands. The murder occurred during a home visit by Shinjo, where Iizuka attacked him multiple times with a knife and an axe while he was on probation for a prior robbery offense.

The case has drawn attention not only for its brutal nature but also for the psychological context behind the defendant's actions. Iizuka acknowledged the charges but claimed that he acted under the guidance of what he termed 'the voice of a guardian deity.' His defense team argued that Iizuka may not have had the mental capacity to understand his actions or may have been in a diminished state of mental function at the time of the crime. However, the court ultimately decided that he possessed sufficient mental capacity, categorizing his actions as an unjustified act of violence against an innocent victim, which highlighted a disturbing trend of misdirected anger towards authorities in his life. The judgment stated that such behavior should be viewed with the utmost severity, equating it to high-level indiscriminate murder.
