A maniac who wanted “to get rid of the disabled from this world” hacked up to 19 people to death in Japan and injured scores more during a stabbing spree at a medical care facility where he once worked, reports said.

The 26-year-old suspect targeted a disabled home in the city of of Sagamihara, which is about an hour-and-a-half west of Tokyo.

The facility provides meals and rehabilitation activities to residents, according to local reports.

Police told the Kyodo news agency that 911 calls started pouring in from staff just after 2:30 a.m. local time, claiming that they had spotted a man dressed in black with blonde hair and a knife on the grounds of the Tsukui Yamayuri Garden facility.

He eventually broke into the building with the knife and began targeting people inside, officials said.

Local media reported that up to 19 people were killed during the attack — and as many as45 were injured, with at least four being in serious condition.

The rampage was among the worst single-perpetrator mass murders in modern Japanese history.

The suspect later turned himself in — telling officers at a nearby police station that he “did it.”

“I want to get rid of the disabled from this world,” the man said, according to the Japanese newspaper, Asahi Shimbun.

Officials said he is a former employee at the home.

Crime is relatively rare in Japan, despite Monday’s incident.

Only one gun death was recorded in the country in 2015 — and just eight crimes were committed that involved gunfire, according to police.

The last major knife attack unfolded last March, when five people were stabbed to death during a rampage on the rural Japanese island of Awaji, near the western city of Sumoto.

A 40-year-old unemployed man was later arrested after the victims — ranging in age from 60 to 80 years old — were discovered in two different houses.

In 2008, seven people were killed after a knife-wielding man plowed his truck into a crowd of innocent bystanders and then got out and started randomly stabbing people.
