Is it possible to live in Japan as a a person with many health problems ?

Hi, it's been years I want to live in Japan, but the thing that stops me from it is that I have a lot of health problems, such as hormonal imbalances and other problems.

I need medication for my hormonal imbalance and I don't know if it gonna be too expensive.

for my other health problems, I also have a colostomy and I need appropriate medical supplies, and it's the same problem than before, I don't know if it's gonna be expensive.

Anyone can tell me if there's something to help people like me in Japan? Like insurance? Thanks.
