South Korea's former President Kim Dae-jung has said he is unhappy with the results of an official report into his abduction from Tokyo in 1973.
Mr Kim spent several years in jail, but became president in 1997
The South Korean National Intelligence Agency (NIA) admitted last week to seizing Mr Kim while he was in Japan.
Mr Kim said the report did not make clear his belief that the agents had originally intended to kill him.
He also said it should have stated that the incumbent South Korean leader Park Chung-hee had ordered the abduction.
With the publication of the report on Tuesday, Japan's Prime Minister Yasuo Fukuda said he now considered the issue closed and urged Japan and South Korea to look to the future.
"I don't think we need to consider pursuing this matter further," he said.
But on a visit to Kyoto Mr Kim told reporters, "I protest to the governments of Japan and South Korea for ignoring my rights."
"For Japan, its sovereignty was violated, but it also infringed on my rights by neglecting in its duty to protect me," he said.
"It is clear that the incident was instructed by President Park and the purpose was murder."
The NIA admitted last week that its precursor, the Korea Central Intelligence Agency (KCIA), kidnapped Mr Kim from a Tokyo hotel on 8 August 1973 and took him by boat to Seoul.
The report said there was some evidence to suggest the kidnap was initially planned as an assassination attempt.
Mr Kim, who was in exile at the time and leading a campaign against Mr Park, previously said he believed the abductors planned to throw him overboard.
He said a US plane flying overhead scared the abductors who then took him to the capital where we was placed under house arrest by Mr Park's government.
The admission by the NIA followed a three-year report into the past conduct of the KCIA, and the agency expressed "deep regret" for its involvement.
It said that there was "physical evidence to support the possibility that, up to a certain point, the plan had been pursued as an assassination".
