!LuaTeX-ja is a macro package to typeset Japanese texts using [http://www.luatex.org/ Lua(La)TeX].
A goal of this project is to provide an equal or superior typesetting system to [http://ascii.asciimw.jp/pb/ptex/ ASCII pTeX], which is a traditional standard Japanese TeX engine.

== Download ==

At this moment, there is no stable version.
You can download the latest versions from the ,#4[http://git.sourceforge.jp/view?p=luatex-ja/luatexja.git Git repository].

!LuaTeX-ja is also available from the following archive and distributions:
 * [http://www.ctan.org/tex-archive/macros/luatex/generic/luatexja CTAN]
 * [http://miktex.org/packages/luatexja MiKTeX]
 * [http://www.tug.org/svn/texlive/trunk/Master/texmf-dist/tex/luatex/luatexja/ TeX Live]
 * [http://w32tex.org/index-ja.html W32TeX] (luatexja.tar.xz)

Recent version of !LuaTeX-ja (20150420.0 or later) requires the followings:
 * !LuaTeX beta-0.80.0 or later
 * luaotfload package (v2.5 or later)
 * 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
/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
}}}

=== Bug information ===
 * With !LuaTeX-ja 20150513.0 (or 20150420.0), accent such as  {{{\"o}}} ''without'' using the fontspec package causes an error like
{{{
ltj-jfmglue.lua:357: attempt to perform arithmetic on a nil value
}}}
   To cope with the error, change {{{lp}}} at l. 357 of ltj-jfmglue.lua to {{{lx}}}, or just use the fontspec package.

 * Current !LuaTeX-ja does not work with  unicode-math package v0.8(a) (see Ticket #35463 (Japanese)).
   Please replace lltjp-unicode-math.sty with that of the development repository (or, the one attached to the ticket). 

Sorry for the inconvenience.
