The father of Lucie Blackman is to go to Japan to give evidence in the trial against her alleged killer.
Lucie Blackman's body was found seven months after her death
Joji Obara is accused of the abduction, rape and manslaughter of Ms Blackman, 21, from Sevenoaks in Kent, in 2000. He denies any involvement in the killing.
Her dismembered body was found in a cave in a fishing village outside Tokyo following a seven-month search.
Tim Blackman, from the Isle of Wight, will tell judges about the impact his daughter's death has had on his family.
His daughter had been working as a hostess in a nightclub in Tokyo when she vanished in July 2000.
Mr Blackman, 52, is due to fly out to Japan on 23 April and present his statement to the court two days later.
He said: "Being called out to give our impact statements is very much towards the end of the trial process.
"The impact of the crime on the victim's family is something the Japanese system takes into consideration when they are reviewing the whole case with regard to guilt and punishment."
During the course of the three-year trial, Mr Blackman has attended the court on numerous occasions.
