A government delegation has returned from North Korea with material that may confirm Pyongyang's claim that Kim Chol Jun was the husband of abductee Megumi Yokota, a senior official said Thursday.
When the government team met with Kim, he refused to provide samples such as hair for DNA tests.
North Korea claims Yokota, who was kidnapped to the country in 1977 at age 13, killed herself in 1994, and Tokyo is trying to get more information about her fate.
