SAPPORO -- A group of Ainu people plan to file a lawsuit this summer against the Hokkaido Prefectural Government to halt the return of Ainu assets that they say are woefully undervalued at 1.3 million yen, a member of the group said Tuesday.

Ryukichi Ogawa, a representative for the plaintiffs, said the Hokkaido government, which plans to return the assets in the form of cash, has failed to take into account inflation and other effects of the past century on the value of the assets.
