The Osaka District Court on Friday sentenced a 25-year-old man to 30 years in prison for stabbing a resident to death with a dagger and injuring his three children at their home in the prefecture in 2016.
The Osaka District Court handed the term to Yuma Kobayashi, for whom prosecutors had sought the death penalty.
Defense lawyers had argued that Kobayashi, who had a history of schizophrenia, was mentally incompetent and could not be held criminally responsible for the attack.
