A memorial service was held in Tokyo on Saturday for 6,830 Chinese forced laborers who died in various parts of Japan during the war after being brought here against their will, the first to mourn all Chinese who perished in such circumstances.

About 300 people — including around 70 from China, families of the dead and monks — took part in the service at a temple in Sumida Ward.

Two Chinese who survived the ordeal also attended.

"I hope the two countries will not only look back on history and pray for peace but also take opportunities such as this memorial service to lead to mutual friendship," Chinese Ambassador to Japan Cui Tiankai said at the event.

Separate memorial services have been held in other places in the past, but this year's event was organized in conjunction with the 60th anniversary of the discovery of the remains of Chinese laborers in a mine in Akita Prefecture, organizers said.

Many Chinese died of poor nutrition, overwork and illness after being brought here to toil in 135 places, such as coal mines and shipyards, across the nation, organizers said.
