american-apa citation using biber with japanese title

I'm writing a document which is entirely written in English. However, I have to cite a Japanese source. I'm using MikTex (and there's no way to change to texlive).

Is there a way to cite the Japanese document in an "all" English document? I'm using apa Style with American language setting and biber.

• Welcome. I would simply use the english transliteration instead of the japanese script. Chances are high, your readers can't read the japanese script anyway. – Johannes_B Jul 25 '16 at 8:20
• The citation rules of my university require the original title as it is. I also think it makes searching for the document easier. – GNA Jul 25 '16 at 8:48
• Depending on how well your document setup can fathom Japanese script that could be as easy as filling the title field with Japanese script. Can you show us an MWE of your document setup so we know what you can use. – moewe Jul 26 '16 at 7:46
• Maybe Change font automatically when typing CJK characters, possibly lualatex will answer your question? – wilx Jul 26 '16 at 10:57
• I tried lualatex. It worked but it is really slow. My current "solution" is to put a CJK-Environment inside of my .bib-File. This is genereated into the bibliography and displays the Japanese letters. This is not a very comfortable and beautiful solution. However, I have only one Japanese reference. So it is okay. – GNA Jul 26 '16 at 12:54

My current solution the CJKuft8 package. I put following in my preamble:

\usepackage{CJKutf8}
\newenvironment{Japanese}{%
\CJKfamily{min}%
\CJKtilde
\CJKnospace}{}

This allows us to open an Environment which can display Japanese characters like this:

\begin{CJK}{UTF8}{}
\begin{Japanese}

\end{Japanese}
\end{CJK}

This environment is also possible in a .bib file.

@Electronic{somesrc,
author   = {{\begin{CJK}{UTF8}{}\begin{Japanese}橋本\end{Japanese}\end{CJK}}},
title    = {{\begin{CJK}{UTF8}{}\begin{Japanese}テスト\end{Japanese}\end{CJK}}},
year     = {2016},
url      = {http://www.some-japanese-site.co.jp},
language = {Japanese},
urldate  = {2016-08-05}
}

Note that theres an extra pair of {} around the environments in the author and title field to prevent biblatex from splitting up the field and therefore destroying the CJK environment.

It's the quickest solution I found so far without changing to another latex version. This is tested with pdflatex on Windows (MikTeX) and Linux (texlive).

UPDATE: For some time now, biber doesn't handle this correctly. It creates too many braces in the *.bbl file. This can be solved by putting

\newcommand{\dojapanese}[1]{%
\begin{CJK}{UTF8}{}\begin{Japanese}#1\end{Japanese}\end{CJK}%
}

into the preamble of the document. The new command can then be used successfully inside an bibliography file:

@Electronic{somesrc,
author   = {\dojapanese{橋本}},
title    = {\dojapanese{テスト}},
year     = {2016},
url      = {http://www.some-japanese-site.co.jp},
language = {Japanese},
urldate  = {2016-08-05}
}
