In addition to checking the Mirlyn catalog, below you will find links to databases that will help you in your search for sources on Japan-related research topics. Remember that not every database has the same access to journals as the other, so it is helpful to try your search for the same terms in two different databases.
Also be sure to look at the links below. They provide bibliographies of published works, dictionaries to help you figure out difficult terms, and broad search platforms (like Google) where you can investigate if someone has written on certain topics by searching the content of published materials.
