Depends on the school
My University, Indiana University Bloomington had an East Asian Language and Cultures Major, which I did, and focused on Japanese. There were of course history and literature classes avaliable.
They also have a History department, in which you can focus on Asia...
I went to Nanzan University in Nagoya for a year, and there they have a Japanese Language program for foreignres, but is completely seperate from the Japanese students ciriculum. When foreigners major in "Japanese" and Japanese major in "Japanese" it is a totally different can of worms.
I currently work in Japan in IT, and can say that no one has ever asked me anything about my Japanese major, they just care whether or not I can keep up in a meeting or not.
My recommendation is to major in History, and take Japanese language classes, and Japanese history classes as electives if you have to every semester. And study abroad!
