It’s illegal to be fat in Japan
Thanks to an anti-obesity law passed last year, Japanese salarymen across the nation are pulling up their shirts to have their guts measured… and if they’re overweight, they face consequences. If you’re male and your waist is over 33.5 inches, you’re considered fat. If you’re female, the limit is 35.4 inches. For every obese employee, the company gets hit by a fine.
The theory is the less overweight people you have, the lower health care costs will be across the board. (source)
