I have just started using latex and I am trying to display Japanese characters on a beamer presentation. I use Miktex on a Windows 7 OS. I have tried every possible example file and tutorial that I found using xelatex of pdflatex, installed all sorts of packages to enable Japanese support and downloaded dozens of japanese fonts. After hours of bug-fixing, I always end up with obscure errors leading to unanswered posts on forgotten threads... In my most successful attempt, I used xelatex with this file ->


\begin{CJK}{UTF8}{min}abc 因子の部屋\end{CJK}

This file doesn't give me error messages, but the output on the pdf file is just "abc" (the japanese is not displayed). I also get this warning:

LaTeX Font Warning: Font shape `OT1/cmss/m/n' in size <4> not available
(Font) size <5> substituted on input line 8.

And nothing else that looks like an error. As I said before, I failed all other foolproof methods/tutorials found here an there on the web (I even crashed my whole PC just by updating a Miktex package), so please be patient with me... Thank you!

EDIT: I don't think this is a duplicate because I tried all that was written in the "duplicate" question and a dozen others before I posted mine, and it did not solve the problem. For the liked "duplicate" example, I got this error message:

Font shape `C70/min/m/n' undefined

Which is apparently because Miktex for windows 7 lacks some font files for ms mincho that I already downloaded and are still not recognized.

This code should work, using TeXworks editor.

% !TeX program = XeLaTeX
% !TeX encoding = UTF-8
\setCJKmainfont{MS Gothic}

If you do use an old package, update it.

For MiKTeX, use the Update utility or Package Manager:

enter image description here

For TeX Live, use TeX Live Manager instead.

    Hi, thank you for your answer. I tried your sample with Texworks in Miktex and Tex live and I got the same error message that I always get. Here it is: ! Undefined control sequence.

If you want to use CJK/CJKutf8 packages to output Japanese characters, you have to generate font files before you compile your source code. Since CJK/CJKutf8 packages are obsolete, I recommend you to use xeCJK package.



Save it as UTF-8 encoding, and compile it with XeLaTeX, you will get: enter image description here

Here, the command \setCJKmainfont{SimSun} load a font file whose name is "SimSun" from your system. You can type fc-list > C:\myfonts.txt in cmd window, and find the font name you can fill in \setCJKmainfont{}.

The xeCJK package is a great work of Chinese LaTeX community, LuaTeX-ja, however, is developed by Japanese. Have a look at its document may also help you.

  • Thank you very mush for you answer. I tried your sample. I got an "utf8" icon at the bottom of the window, so I guess it means the encoding is utf8; but i get an error message: the dreaded "undefined control sequence". What do you mean by "generate font files" ?

  • @Squid: Erh, since you provided no more log info, I do not know what happened on your system. Update your question (edit it), and display the MWE with log info. "Generate font files", however, is a long story. Engine TeX/pdfTeX do not support unicode directly, which is one of the reasons that they cannot use fonts installed in one's system. If you want to insert CJK characters in PDF output, as an example, you have to split the original fontfile into many parts, called 'subfont', who has only 256 CJK characters.

    Commented Oct 17, 2013 at 3:14
  • The package CJK divided any asia characters in TeX source file into two parts---the first part points out which subfont contain the specific character, and the second part gives the position of that character in the subfont (range from 0 to 255). So, if you want to use the package CJK, you have to generate such subfonts as the first step.

You have to run your example with pdflatex and not xelatex. Then it will work. For xelatex you can simply use:

\rmfamily% Code2000 has no sans serif charcters
abc 因子の部屋


or any other font instead of Code2000 which has japanese characters.

enter image description here

  • I used xelatex because I got an error message with pdflatex: "undefined control sequence". I get the same error running your sample with xelatex: "undefined control sequence"...
