All residents in Japan have to have some healthcare insurance or join a healthcare insurance proivider. Basically people can join to KOKUHO (National health insurance). Foreigners who are living in Japan can join too. (If you are an office worker, most large companies will have private insurance. Here is the Sony health insurance site.) Or they join a concerted health insurance association for their industry. This site explains well. Speaking of me, I am office worker, and my company joined the "Tokyo Denshi Kenpo Insurance" (Tokyo technology industry health insurance) association, they give us this type of insurance ID card. When we go to hospital, we have to take this. How much do you need to pay for insurance? It depends on the insurance type, the association, your salary and age. I suppose it would be around 3,000 yen - 8,000 yen per month.
Last week, my American friend had to go hospital, but he had not joined any health insurance scheme yet. It means he has to pay the actual cost. He talked to the doctor, had two X-rays taken, and got medicine for the next two weeks. Then in total he paid around 15,000 yen. Wow expensive! But he said "wow cheaper than I suppose, without insurance, it was pretty nice price". Really? In that case, I would pay 5,000 yen because I have to pay 30% of actual cost in my health insurance. However I have to feel that 5,000 yen is expensive though.
Anyway the association makes us get a health check once a year. And yesterday I got my results for this year which I took in March. They checked blood ( neutral fat, cholesterol, blood pressure, red cell, white cell, GOP, GTP etc.), a chest X-ray, barium study, supersonic ray for system, dipstick test, audiological test, eye test. Since I am a woman, also I got screening for cancer of the cervix and a mammogram. All these checks cost 3,000 yen for me. I think this is reasonable. What do you think?
Sometime I watched the news, people who have cancer gave up trying to be treated in the U.S, and on the other hand in Sweden people can get good treatment. Personally, I don't feel any inconvenience now, but when I get older, 25% of Japanese will be over 65 yeas old in 2015. Health insurance and pension credit issue is really serious for us.
