I am finding it difficult to find information on inequality and discrimination against elderly people.Any help would be appreciated particularly website addresses. Thanks!

Some websites would also be great, with some sources. Or any other problems in Japan that concern you as well. Sources would be nice, please. But the major one is the discrimination against women, thanks.
I ask this because of a research paper that I need to do.

I am 21 years of age with a clean record. I tried to rent a hotel room at the Days Inn in my hometown. I was refused service on the basis that “locals tear up our rooms.” Is this discrimination?
