like Thomas Dye showed in his mail, you have to encapsulate the
Japanese text in LaTeX with \begin{CJK} and \end{CJK}.

You can also use links or macros (using links).  An example (for
Chinese, but Japanese is basically the same, except the fonts):

Put the following in your .emacs:

#+begin_src elisp
  (org-add-link-type
   "zh" nil
   (lambda (path desc format)
     (cond
      ((eq format 'html)
       (format "%s" desc))
      ((eq format 'latex)
       (format "\\zh{%s}" desc)))))
#+end_src

Put the following in the head of your org file:

#+begin_src org
  #+LaTeX_HEADER: %% CJK stuff
  #+LaTeX_HEADER: \usepackage[encapsulated]{CJK}
  #+LaTeX_HEADER: \usepackage[CJK, overlap]{ruby}
  #+LaTeX_HEADER: \usepackage{pinyin}

  #+LaTeX_HEADER: \newcommand{\zh}[1]{\begin{CJK}{UTF8}{gkai}\Large
#1\end{CJK}} % gb2312 kai #+LaTeX_HEADER: \renewcommand{\rubysize}{0.5}

  #+LaTeX_HEADER: %% pinyin 1st and 3rd tone (shortened)
  #+LaTeX_HEADER: \usepackage{newunicodechar}
  #+LaTeX_HEADER: \newunicodechar{ǎ}{\v{a}}
  #+LaTeX_HEADER: \newunicodechar{ǐ}{\v{\i}}

  #+Macro: zh [[zh:][$1]]
#+end_src org 


Then use CJK in your org file like this:

#+begin_src org
  Now you can user CJK characters like {{{zh(你好！)}}} (Nǐ hǎo) or
  [[zh:][你好！]].
#+end_src

Best regards
