UNESCO Draft Decision Asks Japan for More Details on Sado Mine History Presentation

The UNESCO World Heritage Committee released a draft decision on July 15, 2026, recommending that Japan take further steps to reflect the whole history of the Sado mine World Heritage site. The draft followed review of a State of Conservation report Japan submitted in late 2025.

At that time the committee recommended that Japan present the site's whole history across all periods of mining activity. The draft decision states that the interpretation and presentation strategy of the whole history has shown some progress but remains to be fully developed.

It adds that further clarification is needed on how the strategy and facilities address the property's history throughout all periods of mining exploitation.

More than 1,500 Koreans were mobilized to work at the mine during Japan's 1910-45 colonial rule of the Korean Peninsula. Records indicate that 1,519 Koreans worked at the site between 1940 and 1945. The committee recommended that Japan closely consult with relevant parties to improve its interpretation and exhibition strategy and submit a follow-up implementation report by December 2027.

The draft decision is scheduled to be discussed at the 48th World Heritage Committee session in Busan, South Korea, next week. A South Korean foreign ministry official stated that the decision reflects Seoul's position that Japan's implementation of the committee's recommendations remains insufficient.

The official added that South Korea will continue to work with the UNESCO Secretariat and relevant countries to ensure Japan faithfully implements the decisions and commitments made at inscription.
