As I mentioned in a comment under the question, I think it's still too broad even when narrowed down to a single country:
@Matcha_boy98 it's still pretty broad. How a country makes policy is quite complex, too much for an answer here. Consider for example this Wikipedia article on the Government of Japan. I suggest reading such articles first and then asking questions about specific paragraphs that are unclear or questions that are not covered by the Wikipedia article. That way, you can often quote a paragraph and it provides a good introduction into the subject.
Consider that you'd be asked the question in real life, how would you answer? I would go to that Wikipedia page and list a few pointers from there. Alternatively, I'd just point them to Wikipedia page or ask a more specific question.
If we would answer here we'd basically be replicating Wikipedia. Looking at the Wikipedia page, it's rather extensive. So we'd either be giving a short summary, in which case you'd be better of reading the Wikipedia article, or you'd have a very large answer that will need a lot of updating which probably won't happen. In that case, you'd also be better of by going to Wikipedia.
In conclusion, it's really not a good fit for this site, but the author probably had something more specific in mind meaning they could easily edit the question to be more specific. If you have a more specific question, you can ask it as a new question. Reopening this question while it's too broad won't do anyone any good.
