A: There are many courses about Japan, some of which focus entirely on Japan and other that situate Japan in a broader context. The first step is to examine the LSA course guide which lists all of the Japan-related courses offered.
You can do a keyword search for "Japan" and/or check out the course list created by members of the CJS Undergraduate Advisory Board.
Many Japanese language or culture courses are listed under ASIAN or ASIANLAN but there are also others in other departments. Remember that many courses are cross-listed with two (or more) departments. For example, a Japanese History class might be listed under both ASIAN and HISTORY.
