Gunkanjima, or Battleship Island, is one of 23 old industrial facilities seeking UNESCO's recognition as world heritage "Sites of Japan's Meiji Industrial Revolution" meant to illustrate Japan's rapid transformation from a feudal farming society into an industrial power at the end of the 19th century.

UNESCO's World Heritage Committee is expected to approve the proposal during a meeting being held in Bonn, Germany, through July 9 after Japan and South Korea informally agreed on a promise to acknowledge, though it is unclear how, that Koreans were among the people who toiled at Gunkanjima and some other sites. The compromise also includes an agreement by Japan to support South Korean proposals for some world heritage site listings.

Japan's bid for UNESCO recognition is confined to the 1868-1912 era of the Meiji Emperor, who presided over the country's rush to industrialize and catch up with Western colonial powers. It excludes the years that followed, when Japan annexed Korea and eventually invaded China and other parts of Asia before and during World War II.

The proposal makes no mention of the grim interlude when, toward the war's end, tens of thousands of Koreans, and also Chinese and foreign prisoners of war were forced to toil under dire conditions in Japanese factories and mines. ... "There's terrible working conditions, and there's strikes and there's a whole social history that's part of it, and if it's just going to be glossed over, left as a footnote or even left out, then that's an equally big problem," he [Andrew Gordon, a historian at Harvard University] said.
