The ministry of economy, trade and industry on Friday removed photoresists -- used to coat semiconductor circuit boards -- from Tokyo's export restrictions against Seoul, the Asahi Shimbun newspaper and other reports said.
Japan tightened export controls on three materials essential to key products of South Korean tech companies such as Samsung in July after a series of South Korean court rulings ordered Japanese firms to compensate war-time forced labour victims.
The move infuriated Tokyo, which insists the matter was settled in a 1965 treaty normalising diplomatic relations between the two countries, which included significant reparations.
Tokyo's export controls led to Seoul threatening to withdraw from a key military intelligence-sharing pact, alarming the United States who said that would benefit North Korea and China.
South Korea later reversed course and agreed to extend the pact "conditionally".
