LuaTeX-ja wiki

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:

  • LuaTeX beta-0.80.0 or later
  • luaotfload package (v2.5)
    LuaTeX-ja does not support luaotfload v2.6 (released on 2015/12/09) yet.
  • luatexbase package (v0.6 or later)

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
$ kpsewhich -format=cmap  Adobe-Japan1-UCS2
