The number of people with disabilities who were abused at workplaces in fiscal 2017 surged 34.6 percent from the previous year to 1,308, the labor ministry said Wednesday.
The figure marked the highest annual level since the survey started in fiscal 2013. Assaults and the withholding of wages were among the reported cases.
The number of offices where such abuse took place grew 2.8 percent to 597, also the highest level on record.
The increase in the number of reports comes amid the rising employment of disabled people and more awareness of such abuse.
Some cases were attributable to businesses that went bust and failed to pay wages to disabled workers. The number of workers who faced financial abuse, stood at 1,162, or over 80 percent of the total.
A total of 116 people were affected by so-called power harassment, or workplace bullying mainly by superiors, and other forms of psychological abuse.
