Doctor’s notes are usually up to the company to decide. There are various insurances and such as well that can kick in for long-term illness. Japan has a program that pays 60% of salary for some period of time, though I don’t know the details.
To clarify a bit: what I mentioned above is the legal minimum an employer can give me regarding sick days. They are of course free to do more, and I my personal case, I’ll usually just work reduced from home (answer mails and do lightweight administrative stuff) if I’m starting to get a cold or something, get better in a day or two, and come back full time, without logging any sick days, because my employer prefers that I’m available for small stuff and get well fast rather than that I take “full” sick leave if I’m just mildly sick.
