Work-related incidents killed 22 foreign trainees over a three-year period from fiscal 2014, according to government data, illustrating the risk that laborers brought to Japan will face dangerous or exploitative conditions.

While most of the 22 deaths are believed to have been caused by accidents, one was the result of karōshi (death by overwork), the Health, Labor and Welfare Ministry said Sunday.

The ministry's figures are the first government statistics to be released on work-related deaths among foreign trainees in Japan.
