Police are currently looking into the motive behind the attack, which happened in the city of Sagamihara, just west of Tokyo.
Images from the scene showed many ambulances near the Tsukui Yamayuri En (Tsukui Lily Garden) facility, which accommodates people with disabilities.
The attack took place at around 2:30 am local time on Tuesday. The knife-wielding man entered the facility from the outside and began attacking people, according to police.
Later, at around 3 am, a man reportedly turned himself in, saying: “I did it,” according to local media. A report by Daily-News.jp said that he was a former employee of the facility.
One resident told NHK that the man detained had blond hair and was wearing black clothes.
