While Japan has great national health insurance, you still have to pay 30% of it. So a month supply of Concerta will still cost you $100, which is a lot better than in the US without insurance, but it's not free.

What's nice are the yearly comprehensive medical checkups, what's not nice is your employer pays for it and gets a copy of the results too.

Japan has monthly and yearly caps, as well as discounts for chronic diseases and for people with low or no income. So while it's true that you pay 30% yourself, the people who would have difficulty paying that 30% are also taken care of.
