What are Japan's medical achievements?

Many of the Nobel Prize winners in medicine have been Japanese scientists. This is a direct reflection of the fact that Japan is really good at medicine. For example, Professor Yoshinori Ohsumi was awarded the Nobel Prize for Medicine in 2016 for his work on cellular autophagy. Japan's achievements in medical theory are complemented by its advanced medical equipment and research. For example, the world's most advanced endoscopes, microscopes, CTs, and electronic endoscopes are basically developed in-house. In modern medicine, Japan is still more powerful, it is worthwhile to learn from us.
