Depending on what I was researching. I may have used Japanese websites for business information and for social Practices. I also used the actual schools I referenced in the novels websites for information and being a former student at them I know the general layout.
For other parts such as the judicial systems I used the government of Canada's sites and legal books that I had kicking around my house.
There are great books in the library that cover a wide range of topics.
