A total of 103 cases of inpatient alcoholics in Japan and 67 cases in China were compared on the patient history, family history, marital status, course of dependence‐formation, alcohol‐related psychoses, etc. Between Japan, which is suffering from an already increased rate of alcoholics, and China, which is now confronted with an increasing rate of alcoholics, the following findings were observed. The period from the beginning of habitual drinking to the first drinking bout fit was found to be shorter in China, that is to say, alcohol dependence may be formed more rapidly in China. The frequency of types of withdrawal psychoses was similar in both countries. The jealousy delusion seldom appeared in Japan and yet often in China. The condition whereby family bonds are not destroyed in China was discussed as a considerable factor for the manifestation of jealousy delusion.
