Nicola's dad and uncle are planning to visit the university in Takasaki where the exchange student was spending 10 months.
They intend to visit her room there, but said they would not be visiting the hotel where Nicola’s body was discovered in a room in the early hours of May 24.
The student had attended a Nicki Minaj concert with a friend and had gone to the hotel for dinner and drinks afterwards with two men they met at the concert.
It is suspected by police that their driks may have been spiked.
Mr Furlong said: “I don’t think we will travel to the hotel, I think that would be a step too far. But we will try to bring back some of her stuff. She had two laptops out there. I want to get into her room. That will be the most difficult part.”
He explained to reporters that he wanted the laptop computer as he had bought it for his daughter and knew there were nice photos of her saved on it.
The father-of-two said in the departures lounge: “I can’t wait to get home to my other daughter Andrea, and we are not even out of Dublin.”
Earlier in the week the distraught boyfriend of Nicola Danny Furlong (22) told the Irish Independent that Nicola's homecoming next month should have been the "happiest day of our lives".
"I always said that the day she was home would have been the happiest day of both of our lives," said Danny, a promising young footballer, adding that the couple had planned to go on a sun holiday together.
Danny helped carry Nicola's pink coffin to the church in Wexford for her funeral Mass last Sunday.
Nicola’s dad and uncle are expected to make the 9,500 mile return to Ireland next Tuesday.
Mr Furlong said he expects to be returning again to Tokyo for a trial along with her friend who was assaulted the night of Nicola's murder, although it is believed she recalls little of the attack.
