+ the \Pkg{fontspec} package, but only standard NFSS2.
+

+Note that the \Pkg{fontspec} can coexist with the option as the following:
+\begin{lstlisting}
+\usepackage{fontspec}
+\usepackage[hiragino-pron,nfssonly]{luatexja-preset}
+\end{lstlisting}
+Note that the functionality of the \Pkg{luatexja-fontspec} package, such as
+ \cs{setmainjfont}, cannot be used in the example above.
