What's the difference between Class I and Class II and Class III drugs in Japan?

This answer is completely wrong! Japanese drugs are divided into Class I drugs (prescription drugs), Class II drugs (you can buy them only after consulting qualified pharmacists) and Class III drugs (you can buy them at will). The first kind of drugs can only be prescribed by doctors (pharmacists have no prescription right) and purchased in the "prescription drug bureau" (any pharmacy or individual selling prescription drugs is a serious illegal act and will be arrested and prosecuted). Japan's first-class drugs are completely purchased by the national medical insurance system. The law prohibits hospitals from setting up affiliated pharmacies, and drugs such as hospitalization cannot be sold to the outside world. Generally, a third party will set up a "prescription drug bureau" next to the hospital to handle prescription drugs, and the hospital and the prescription drug bureau will adopt a unified medical insurance system. The drugstores on the street (called drugstores in China, which sell medicines and cosmetics) can only sell the second category (medicines requiring the guidance of pharmacists such as colds, headaches and fevers) and the third category (band-AIDS, etc.). ). All drugs in Japan will be marked with the words "Class I drugs" in the lower right corner.
