TOYAMA, Oct 22 — A Japanese court handed down an eight-year jail sentence on Tuesday to the father of a woman who publicly accused him of rape, a rare case in the country where many victims stay anonymous.

Koji Daimon was convicted of raping his daughter Riho Fukuyama in 2016, when she was in high school.

He admitted to the act but maintained his innocence, arguing that “my daughter was in a state where she could have resisted”.

In the ruling, judge Toshiaki Umezawa said that “given that the victim continues to suffer physical and mental distress to this day... the consequences must be deemed grave”.

Fukuyama says the rapes began when she was in junior high school, when her mother was not at home.

Fukuyama went public in March last year following the arrest of her father.

Just a handful of other victims of similar crimes have revealed their identities in Japan.

“I was relieved” after hearing the ruling, Fukuyama told reporters gathered outside the court in Toyama, a coastal city in central Japan.

“I want to tell the world sexual violence within families does exist. Please don’t look away from victims.”

At a press conference later, she said: “I want to tell myself: well done.”

But she described the trial as “extremely tough”.

“It was painful to talk about things I wouldn’t discuss even with close friends, like in what (body) position” she was raped, she said.

“I had to return to my past self and vividly recall the details.”

Fukuyama said she has suffered from flashbacks and nightmares in the years since she was raped.

Her husband Yoshiki Fukuyama, also present at the press conference, said she used to cry for hours and only felt safe with four locks on the door.

“I want people to know this is the reality of those who have suffered sexual violence,” he said tearfully, urging people to “stand up” for other victims.
