Physicians and nurses at a national hospital in Osaka are allowed to rack up a whopping 300 hours of overtime per month under a labor-management agreement, according to documents obtained by a lawyer.

The limit is three times the government-recognized high-risk threshold of death from overwork.

Under the agreement signed by the hospital and a workers' representative, around 700 doctors and nurses at the National Cerebral and Cardiovascular Center Hospital in the city of Suita, Osaka Prefecture, are eligible to work up to 300 extra hours a month and 2070 hours of overtime per year.
