There are no public restrooms in subway station, building and somewhat you can imagine or used to. Few local shopping malls have restrooms which allow public access.
If you have a bio issue urgent, I suggest you run into any shop and ask for a key to restroom if you can bear the embarrassment.
Tip. Every McDonalds have restroom and it is free to access.
