I haven't lived in Japan, but my understanding is that it is bizarre. For instance they don't do organ transplants at all. period. none. They also visit the doctor 15 times per year on average, which means they go to the doctor when they are not actually sick, so the doctors are in the habit of not actually treating anyone.

Japan may have the highest life expectancy of any country in the world, but Japanese people in the US live about 5 years longer on average than Japanese people in Japan.
