Some of the Korean people forced to work for Mitsubishi Heavy Industries during World War Two are pressing a local court to sell off the firm's South Korea-based assets to compensate them.
South Korea has already frozen 680-thousand U.S. dollars worth of Mitsubishi Heavy Industries' local patent rights and assets.
The victims' lawyers said Tuesday that they had asked the court to go ahead and sell those.
The Japanese has not followed follow the Supreme Court's ruling last November ordering it to give five people compensation of between 85-thousand and 129-thousand dollars each.
Japan insists the issue was resolved when Seoul and Tokyo established diplomatic ties in 1965, but the lawyers say their clients are very elderly and can't wait any longer.
