The number of disabled employees at 35 of the 43 state institutions stood below the level required by law as of June 1 this year, the welfare ministry said Tuesday.
The actual hiring rate for people with disabilities stood at 1.22 percent, falling short of the statutory target of 2.5 percent.
Of the total, 28 of 34 central government ministries and agencies failed to reach the statutory hiring rate.
State institutions were found to have a shortage of nearly 4,300 employees with disabilities in total. The National Tax Agency alone was more than 1,000 workers short of the required level.
Among municipalities, the number of disabled workers was insufficient in 40 percent of all prefectures and 30 percent of cities, towns and villages.
The actual hiring rate stood at 2.44 percent for prefectures and 2.38 percent for cities, towns and villages.
The employment situation for disabled people at private companies, which is usually released at the same time as that of state institutions, will be announced in March due to a delay in conducting the tally, the ministry said.
In August it came to light that central government ministries and agencies had substantially padded the number of disabled people reported as among their staff.
The central government will hold its first-ever unified exam for disabled people in February, to boost hiring. Ministries and agencies also plan to move forward individually with recruiting activities, aiming to hire more than 4,000 people with disabilities by the end of next year.
