Prime Minister Junichiro Koizumi has told the family of Kaoru Hasuike that he will try to resolve the North Korean abduction issue in a "convincing" way, Hasuike's brother, Toru, said Monday.

Hasuike is one of five Japanese who returned in October after being abducted by Pyongyang agents in 1978.

In a letter sent to Hasuike's relatives in Kashiwazaki, Niigata Prefecture, Koizumi said, "The Japanese government is resolved to making the utmost efforts to resolve the abduction issue in a way that is convincing to everyone."
