I saved this as testmendex.tex,

--8<---------------cut here---------------start------------->8---
\documentclass{jsbook}
\begin{document}
if only I spoke Japanese!
\end{document}

%%% Local Variables:
%%% mode: japanese-latex
%%% TeX-master: t
%%% End:
--8<---------------cut here---------------end--------------->8---

restarted Emacs, did `M-x dired RET', point on file, `RET' and I cannot
reproduce the error.

Ok, thanks for checking.

Thanks.  My last idea would be that you have touched one of the
variables mentioned in documentation as obsolete and AUCTeX gets upset
about it:

--8<---------------cut here---------------start------------->8---
The former customize options japanese-TeX-command-default and
japanese-LaTeX-command-default are obsolete.  Use
japanese-TeX-engine-default instead.  If you need to customize the
executable file name such as ‘"latex"’, the options for them, or both,
customize TeX-engine-alist.

Also, the option japanese-TeX-command-list is considered as
semi-obsolete. It still functions as before, but in theory, it is not
required anymore in normal use.
--8<---------------cut here---------------end--------------->8---

Sorry if the answer is not satisfactory.

Best, Arash
