A group of current and former workers at mover Hikkoshisha Co. filed a lawsuit Friday with the Nagoya District Court against the company, seeking some ¥70 million in compensation for lost wages used to reimburse for damage incurred during transit.

The 12 plaintiffs, calling the company's practice unjust, demanded that its Nagoya branch and other subsidiaries of the Hikkoshisha group remedy the situation.
