Health insurance questions

I need a rough estimate of what it will cost me.
See I have a sezier condition. So I need to take medicine everyday.
In the US I subscribe to perscription insurance cause the cost of
perscription drugs in the US is rediculous. So instead of spending like
1200 a year I spend around 300 a year.

Anyway in japan. I need to know how much coverage i'll get for perscription drugs and doctor visits and how much the monthy rate is.

I'm sure someone in japan already in a similiar sitatution would have
some detailed info. I just need a rough cost est so I know what to expect.

Thanks

Galvin, sorry we can't be of much help, but one question for you -

Will your employer provide coverage or do you need to find your own?
