LuaTeX-ja is a macro package to typeset Japanese texts using Lua(La)TeX. A goal of this project is to provide an equal or superior typesetting system to ASCII pTeX, which is a traditional standard Japanese TeX engine.
At this moment, there is no stable version. You can download the latest versions from the ,#4Git repository.
LuaTeX-ja is also available from the following archive and distributions:
Recent version of LuaTeX-ja (20150420.0 or later) requires the followings:
Also, three CMap files UniJIS2004-UTF32-{H,V} and Adobe-Japan1-UCS2 must be found by Kpathsea. You can check this by kpsewhich command:
$ kpsewhich -format=cmap UniJIS2004-UTF32-H /opt/texlive/2013/texmf-dist/fonts/cmap/adobemapping/aj16/CMap/UniJIS2004-UTF32-H $ kpsewhich -format=cmap Adobe-Japan1-UCS2 /opt/texlive/2013/texmf-dist/fonts/cmap/adobemapping/ToUnicode/Adobe-Japan1-UCS2
With new luatexbase package (2015-10-01), LuaTeX-ja with the fontspec package causes an error like
! Undefined control sequence. <argument> \xetex_suppressfontnotfounderror:DAn example source is the following:
Fork
edit\documentclass{ltjsarticle}
\usepackage{fontspec}
\setmainfont{TeX Gyre Termes}
\begin{document}
\end{document}
We guess that this error is caused by loading the expl3 package after the luatexbase package (LuaTeX-ja reads luatexbase, and fontspec reads expl3 internally). So, please insert \RequirePackage{expl3} just before \RequirePackage{luatexja-core}[...] in luatexja.sty.
Sorry for the inconvenience.
