I would be hard pressed to suggest a college that has courses
only in anime and manga, as the style and techniques you're looking to draw from originated in Japan.
If that
is the direction you're looking to go, however, I recommend a solid foundation in studio art and then completing a graphic design major. You'll find that animation and comic book art are two separate creatures, even though the beginning stages of each are similar - basic design, storyboarding, etc. That's why it's rare to find, even in Japan, anime series that are drawn by the artist of the original manga. More often, the basic premise and general designs are co-opted by a studio of artists for the animation.
The studio art portion of my major (Art Therapy) requires the following courses (which are standard for many studio art based majors):
3 Credits Art History/Criticism/Appreciation (There's a wide variety of courses that apply to this section; Black Art, Ancient to Medieval, Renaissance, Modern, etc.)
3 Credits Aesthetic Experience (These are generally "Art 101" courses that let you dabble in a lot of things.)
9 Credits Art Foundation (2-D Design, 3-D Design and one (1) of your choice from Drawing, Art History Survey: Renaissance to Modern Art, Modern Art, Art Seminar
9 Credits Studio Art (Development of a 'portfolio' showing proficiency in painting, drawing, and 3-D media is required for most majors.)
Most art students also have to put together both a Sophomore and Senior Review and a Senior Exhibition, in addition to their portfolio review.
If you take a studio class like Drawing,
normally there's less emphasis on comic-style drawing and more emphasis on drawing from life and from still life. Our class alternates between three clothed models and a nude model, and I'm a nude model for a different Drawing class. Especially at the lower level courses (100-200-300), emphasis is placed on developing technique, learning use of space, light and dark, etc. There's also usually an attempt to integrate learning other materials - moving away from strictly pencils or ink pens and also using charcoal, various pastels, washes, etc.
Once you have the foundation down, then you can look at fine-tuning your own art for using in comics and possibly look at a graphic design or animation major, whichever seems to interest you more.
I hope that gives you some ideas for what to look at when exploring colleges!
