Japanese classes written by Haruhiko Okumura (okumura@edu.mie-u.ac.jp).
jsarticle, jsbook, and jspf classes are provided. In addition, several
style files are provided, too.

The classes themselves do not automatically enable the support of
Japanese language. You'll need set up LaTeX environment appropriately
so that it can handle Japanese, not only LaTeX itself but also viewers
of outputs.
