Japanese classes written by Haruhiko Okumura (okumura@edu.mie-u.ac.jp).
jsarticle and jsbook classes are provided. In addition, okumacro.sty,
okuverb.sty and morisawa.sty are included.

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.
