The operating cost of Shenyuan Memorial Hospital in Japan is about twice the domestic average, and the medical expenses of top hospitals in Japan are not high. The outpatient fee of Shuntian Hospital affiliated to Shuntian University, which ranks first in Japan, is 4,500 yen, which is similar to that of domestic experts, but still much more affordable than the outpatient fee of 500 dollars. The cost of treatment in Japan is about twice that in China. The cost of cancer treatment in Japan is about 4 million yen, equivalent to 250,000 RMB, and proton therapy needs about 250,000 RMB. The cost of immunotherapy for cancer patients in Japan is about 20,000 RMB each time, and the cost of PET-CT 1.5 million in Japanese hospitals. Mr. Wang Shi, a writer, paid about 500,000 yen for coronary CT examination in Shenyuan Memorial Hospital. Our leader went to Shenyuan Memorial Hospital for cardiovascular examination through Hangzhou Wuzhou Hospital, a company providing overseas medical services. At the beginning, he asked Hangzhou Wuzhou Hospital to make an appointment for the package selected by Mr. Wang Shi, including carotid ultrasound and coronary artery calcification assessment. Except for coronary CT, I feel that the cost is similar to that of these big hospitals. The specific price and process are shown to us in Hangzhou Wuzhou Hospital.
