The medical records that Pyongyang provided for Megumi Yokota, a Japanese national abducted to North Korea who the Stalinist state claims is dead, are "highly credible," the head of a delegation investigating the North's abductions said Wednesday.

"There were police and doctors among the Japanese delegation, and looking at it from an overall perspective, (Yokota's medical records) appear to be highly credible. That is the impression I got," Mitoji Yabunaka, director general of the Foreign Ministry's Asian and Oceanian Affairs Bureau, told a meeting of the House of Councilors special committee on the North Korean abduction issue.
