Under a national law that came into effect two months ago, companies and local governments must now measure the waistlines of Japanese people between the ages of 40 and 74 as part of their annual checkups.

Often referred to as the "Metabo Law," this 2008 regulation requires companies and local governments to measure the waistlines of Japanese citizens aged 40 to 74 during their annual physicals. The goal is to combat metabolic syndrome and rising healthcare costs. Men must stay under 85 cm (33.5 inches) and women under 90 cm (35.4 inches). If an individual exceeds these limits, they are given health counseling and lifestyle guidance. It is important to note that it is not "illegal" to be overweight in Japan; individuals aren't fined or jailed. Instead, the financial burden falls on the employers and local governments, who can face hefty fines if a significant percentage of their employees or residents fail to meet the health targets over time.
