The father of a woman abducted by North Korean agents decades ago has again called for her return in a written comment released on her 65th birthday.

Arimoto Keiko was 23 when she was abducted in 1983 while traveling in Europe after completing a study program in London.

Her 96-year-old father Arimoto Akihiro celebrated her birthday on Sunday with cake and red bean rice at his home in the city of Kobe, western Japan.

In his comment, he said he cannot directly wish his daughter a happy birthday because she is not with him.

Arimoto also said all he can tell his daughter right now is to wait a little longer.

He added that he does not intend to pass on to his children the abduction issue that has yet to be resolved after many years of effort.

Arimoto said that although he is 96, he will continue to think about what can be done toward a resolution for as long as he lives.

He also referred to US President-elect Donald Trump, who will be inaugurated on January 20.

Arimoto said he thinks Trump's support is necessary to resolve the issue. He expressed hope to convey his wishes once again if he gets a chance to meet Trump in Japan.

Arimoto also reiterated a call for Japan's government to closely coordinate with the United States.

The government says at least 17 Japanese citizens were abducted by North Korea in the 1970s and '80s. Five have returned home. The other 12 remain unaccounted for.
