Compensation Claim Case (Forced Labor)

In 2026, the Tokyo District Court adjudicated a damages lawsuit filed by Kim Soon-ja, a South Korean survivor of wartime forced labor, against Mitsubishi Heavy Industries. Kim alleged she was forcibly conscripted and subjected to inhumane treatment at the company's munitions factory in Japan during World War II. She sought compensation for physical and psychological harm. The Japanese court examined whether the 1965 Agreement on the Settlement of Problems Concerning Property and Claims and on Economic Cooperation between Japan and the Republic of Korea extinguished individual claims. The court ruled that the treaty precluded private suits, dismissing the case. The decision reignited historical grievances and diplomatic strains between Japan and South Korea.

The Tokyo District Court dismissed the lawsuit, holding that all individual claims were settled conclusively by the 1965 treaty, and no further recourse could be granted under Japanese civil law.

The central dispute was whether the 1965 bilateral claims agreement permanently waived individual victims' right to seek compensation, or whether crimes against humanity and forced labor claims survive such state-to-state settlements under international law.

The ruling drew sharp criticism from South Korean civic groups and the government, leading to large-scale protests in Seoul and a temporary downgrade in diplomatic exchanges. It fueled public debate in Japan over historical accountability and further complicated bilateral efforts to resolve colonial-era grievances, underscoring the enduring legal and moral complexity of wartime reparations in East Asia.
