I got a few inquiries about this over the summer — The CofC currently does not offer a degree in Japanese or Japanese Studies. However, you can major in something else, get a degree in it, and minor in Japanese Studies. For questions related to admissions, tuition, etc., please visit the College of Charleston: Future Students site, where you can ask such questions.
I am doing some thesis work and found your blog on google. If you don’t mind I may use some of this information, I’ll contact you if this happens. Thanks.
