However, Aoba’s defense lawyer has now filed an appeal in an attempt to block his execution.
The appeal instead focuses on whether the now 45-year-old Aoba’s mental condition at the time allows him to be held legally responsible for his actions.
Aoba has been sentenced to death by hanging, the standard form of criminal execution in Japan.
On Thursday, a verdict and sentencing were handed down in Kyoto district court for Shinji Aoba, who in July of 2019 carried out a murderous arson attack on the Fushimi studio of Kyoto Animation, killing 36 people.
