I suddenly got sick in Japan. What should I do if I get sick in Japan?

If it is a minor illness, such as a cold, fever and runny nose, you can buy some cold medicine in Japanese pharmacies. If it is serious, you have to go to the hospital for examination. However, if it is a tourist visa, all medical expenses must be paid at your own expense (Japanese or people living in Japan only need to pay 30%), which is relatively expensive. However, if you have insurance in China, you can go back to China with an invoice from a Japanese hospital for reimbursement. I hope it helps you. Good luck.
