A Japanese man has admitted killing 19 disabled people at a care home near Tokyo in 2016 but pleaded not guilty because he claims he is mentally ill.
Satoshi Uematsu, a former employee at the care centre, is charged with numerous crimes, including murder.
In interviews, the 29-year-old has said severely disabled people are harmful to society and should be killed.
The case is one of Japan's worst mass killings and has shocked people in a country where violent crime is rare.
The case has also raised questions about Japan's treatment of disabled people. Almost all of the victims will not be named at the trial - apparently because their relatives fear the stigma associated with having a disabled family member.
Mr Uematsu faces the death penalty if convicted. The court's verdict is expected in March.
