Japan is seeking arbitration in a dispute with South Korea over the wartime labor issue.
South Korean courts have issued a series of rulings ordering Japanese firms to pay damages to those who say they or their relatives were forced to work for them during World War Two.
Japan has repeatedly requested talks on the issue with South Korea in line with a 1965 bilateral agreement. But South Korea has not responded.
Earlier this month, some plaintiffs in South Korea announced that they have started selling stocks they seized from the Japanese firms.
On Monday, Japan asked the South Korean government to establish an arbitration panel that includes a member from a third country.
