On a crisp February morning, four elderly Korean men bowed their heads toward Japan*s Seto Inland Sea as the surf lapped near their shoes.

They were paying respects to relatives entombed in a coal mine deep beneath their feet 80 years ago 〞 among thousands of Korean bodies scattered across Japan in an enduring symbol of a colonial past that has long blighted ties between the neighbors.

But with renewed diplomatic efforts to improve relations, families of the men drafted to support Japan*s war effort in what is known as the Chosei mine during the country*s 1910-45 occupation of the Korean Peninsula, see a last chance for closure.
