It is suprised that each Japanese family has relatives psychotic. I am not making a joke, it is true. In Japan,almost one in five people is neuropathic. To the end of September 2021, there are 8,605 hospitals in Japan，1,076 of them are psychiatric hospitals which make up 12.6% in total, 340,000 psychiatric beds that account for a fifth of the world's beds for mental patients that remain highly used, far above the world average. NAKAO IWATA(岩田仲生) a professor of Psychiatry Department of Psychiatry, Fujita Health University School of Medicine, Toyoake, Aichi, JAPAN, published a report in the “Molecular Psychiatry” of US, saying that a special gene called “NOTCH4” in Japanese bodies related to all of this phenomenon. SASAKI Tsukasa(佐々木 司), a professor at the field in Tokyo University, says that there are one out of every five Japanese people diagnosed as mentally illness which conservatively estimated that at least 25,160,000 Japanese are being suffered from psychosis in the society nowadays.
