The family of a Japanese woman abducted by North Korea slammed Kim Jong Un as a “foolish leader” — as they called for the safe return of all kidnapping victims in the Hermit Kingdom, according to reports.

“I think [Kim Jong Un] is a foolish leader,” said Tetsuya Yokota, whose sister Megumi was kidnapped in November 1977, UPI reported.

He and his twin brother, Takuya, have long advocated for the return of Japanese abductees from North Korea along with their mother, Sakie, and father, Shigeru, a prominent activist who died last week without ever reuniting with his daughter.

Megumi was 13 when she vanished on her way home from school in Niigata, in northwestern Japan, but it wasn’t until two decades later that it was revealed that North Korea was behind the abduction.

Japan claims that North Korea abducted at least 17 people to train agents in Japanese language and culture to spy on South Korea.

North Korea confirmed Megumi was abducted but has since alleged that she struggled from depression and died by suicide in 1994, according to UPI — but the family has never accepted that claim.

“Father deeply cherished our sister,” Takuya reportedly said. “It is unbearable to think of how much he wanted to see her.”

The family again called for North Korea to return Japanese abductees to their families Tuesday, saying there are “elderly people, whose health is not good.”

“We hope there are concrete results in order to prevent the same things from happening again,” Tetsuya said, the outlet reported.
