219 businesses (64.6%) broke the law by having their drivers work behind the wheel more than the legal maximum of eight hours a day and 40 hours a week, or longer than what was agreed upon with their labour union.

It also found 37 businesses, (10.9%), did not provide "at least one day off a week," which the law obliges employers to give their drivers.

Also, it found that 260 (76.6%) did not observe standards involving bus driver working hours, which prohibit them from working more than 16 hours a day in combined driving and office time.

Kimura states that the officers, who number 250, have little experience and see no patients nor practice medicine after being hired by the ministry.

Thus, says Kimura, Japan's public health policies lag behind other developed countries, by "decades".
