Japanese pLaTeX and upLaTeX formats and packages often conflict with other LaTeX packages which are unaware of pLaTeX and upLaTeX. In the worst case, such packages throw a fatal error or end up with a wrong output. The goal of this package is that there should be no need to worry about such incompatibilities, because specific patches are loaded automatically whenever necessary. This helps not only to simplify source files, but also to make the appearance of working pLaTeX or upLaTeX sources similar to those of ordinary LaTeX ones.
