The son of Yaeko Taguchi, a Japanese who was abducted by North Korea in 1978, said he wants to find out what his mother was like when he meets Kim Hyon Hui, a former North Korean agent believed to have learned Japanese from Taguchi, probably by the end of this month.

"I would like to ask (Kim) about (my mother's) gestures and favorite things so I can get an image of her," Koichi Iizuka, 32, said in a recent interview.

On Saturday, sources familiar with the situation said the meeting is expected to take place in South Korea later this month.
