This package enables users to declare in their document which physical fonts should be used for the standard Japanese (logical) fonts of pLaTeX and upLaTeX. Font setup is realized by changing the font mapping of dvipdfmx, and thus users can use any (monospaced) physical fonts they like, once they properly install this package, without creating helper files for each new font. This package also supports setup for the fonts used in the japanese-otf package. System requirements: TeX format: LaTeX. TeX engine: pTeX or upTeX. DVIware: dvipdfmx. Prerequisite packages: atbegshi.
