Though there’s a minority opinion to the contrary, conventional wisdom says that regular health checkups are the only way to prevent the development of major illnesses, so, logically, they should also help reduce healthcare costs in the long run. This is the concept behind tokutei kenko kensa, or “special health checkups,” that were started six years ago by the Ministry of Health, Labor and Welfare. The main target is metabolic syndrome, the inevitable gain in fat that accompanies midddle age and which, unchecked, is thought to be the gateway to many so-called lifestyle diseases, like diabetes.
The idea is that local governments would provide checkups to insured residents between the ages of 40 and 74 with national insurance, which, in principle, doesn’t cover regular general health checkups since Japan’s public health system is designed to treat existing problems. If the special checkups uncover unhealthy situations, then the individuals are advised with regard to better diets or exercise regimens, or even pharmaceutical assistance, so as to head off costly treatment down the road, like, for instance, dialysis, which can cost on average ¥5 million a year, most of which ends up being paid for by the government, both local and central.
