In July 2021, the Japanese government and UNESCO briefly engaged in a war of words over heritage sites and Japan's legacy of forced labor. When UNESCO reprimanded  Japan for failing  to acknowledge the use of forced labor during wartime at a UNESCO heritage site, the Japanese government promised to issue a formal rebuttal, and said that it is “sincerely making good ” on the promise to remember victims of forced labor.
On July 12, 2021, UNESCO issued a draft decision  stating that Japan still needed to improve the way it talked about the historical use of forced labor at former industrial installations now recognized collectively as a World Heritage Site. UNESCO followed this with a formal reprimand  on July 22, 2021, over Japan's seeming unwillingness to tell the “full history” of the former industrial sites.
The row centres around “Sites of Japan’s Meiji Industrial Revolution: Iron and Steel, Shipbuilding and Coal Mining ,” 23 historical sites on the western island of Kyushu that are designated collectively as a UNESCO Cultural World Heritage Site . The 23 sites are recognized as the birthplace of Japan's rapid industrialization in the latter half of the 19th century.
The UNESCO reprimand came after an information center , built in Tokyo specifically to explain and celebrate the Meiji Industrial Revolution UNESCO World Heritage Site on Kyushu, failed to inform visitors that some of the locations were the scene of wartime forced labor of Koreans.
Prior to the reprimand, the draft decision on July 12 had noted that the Japanese government, as part of its original UNESCO submission in 2015, said  it was:
[…] Prepared to take measures that allow an understanding that there were a large number of Koreans and others who were brought against their will and forced to work under harsh conditions in the 1940s at some of the sites, and that, during World War II, the Government of Japan also implemented its policy of requisition. Japan is prepared to incorporate appropriate measures into the interpretive strategy to remember the victims such as the establishment of information center.
The UNESCO reprimand noted that Japan had not fulfilled this obligation and focused specifically on forced labor that occurred on Hashima, a coal mine located on an island off the coast of Nagasaki Prefecture in western Japan. Best known around the world as “Battleship Island, ” Hashima, also the site of one of Japan's first coal mines , was featured in the James Bond movie “Skyfall. “
Japan has until December 1, 2022  to implement UNESCO's recommendations about acknowledging forced labor.
The mine on Hashima was operated by giant conglomerate Mitsubishi, which relied on forced Korean labor during World War II to extract coal. At least 800 Koreans were sent to Hashima during the war, 134 of whom reportedly  died while working there.
Another fact so far officially unacknowledged by interpretive materials is that other industrial facilities in UNESCO's “Sites of Japan’s Meiji Industrial Revolution: Iron and Steel, Shipbuilding and Coal Mining” also relied on forced labor. For example, Mitsui, another industrial conglomerate, relied on prisoners of war slave labor to operate its Miike coal mine in Omuta, Kumamoto.
Despite its status as a UNESCO World Heritage Site, there is no acknowledgement of this part of Miike's history.
“Japan has a responsibility under its UNESCO World Heritage agreement to tell the full history of [Miike] and other ‘Meiji Industrial Revolution’ sites.”

With a new government and political system, Meiji entrepreneurs in Japan quickly capitalized on new opportunities to trade with Europe, the United States, and other places around the world.
These local entrepreneurs and the new Japanese government itself also imported  new industrial technologies from abroad, including mining, steelmaking, manufacturing, and shipbuilding, in an effort to match the capacity of Western powers and in the process, jump-starting an industrial revolution .
While the center of Japanese economic and political life was in Tokyo , in the east, in the early Meiji era the western island of Kyushu  is generally regarded as the cradle of Japan's industrial revolution. This was due to established trade routes with China stretching back more than a thousand years, and with relatively newer oceanic trade connections with Europe.
For example, the city of Nagasaki and the surrounding regions were the scene of Japan's first drydock and shipyards, which were powered in part by coal mined from nearby Miike  and Hashima . The shipbuilding facilities in Nagasaki  would eventually produce some of the biggest and most complex warships in the world, and would be targeted  for atomic attack by the United States in August 1945.
Japan's “Sites of Japan's Meiji Industrial Revolution” initiative, as well as the controversial UNESCO Heritage submissions seek to memorialize and celebrate this heritage.
“Very little of Japan's history of industrialization presented at their new UNESCO Heritage sites is true,” says historian Mindy Kotler in a July 2021 newsletter. Kotler is the director of Asia Policy Point , a Washington, D.C. research center studying the U.S. policy relationship with Japan and Northeast Asia.
In a July 2021 article  about Japan's UNESCO initiatives, Kotler points out that the mines, foundries, and wharves that form the core of the Japan's UNESCO World Heritage list typically omit a key historical detail:
The Japanese, however, left out any mention of […] forced labor and abuse, which was the substance of the hundreds of war crimes trials throughout the postwar Pacific.
UNESCO approved the designations in 2015 but conditioned the designations on a promise to provide a “full history” of these sites. Yet, six years later, Japan has not fulfilled this promise.
While Japan has until December 1, 2022 to implement recommendations about acknowledging forced labor, there is little chance that the UNESCO designation will be rescinded, according to a South Korean government official.
A South Korea foreign ministry representative said :
UNESCO withdraws inscriptions only when the site has been altered beyond its original state and character that made it worthy of inscription […] UNESCO has informed us that the current issue regarding the sites in Japan is not something that calls for re-evaluation of the inscription decision.
