Does Overleaf support pTeX?

Yes, Overleaf can compile Japanese documents that require pTeX. Here's how:

  1. A pTeX document does not need special commands for Japanese text (kanji, hiragana and katakana). Here's a simple example (using the jsarticle document class): 
    \documentclass{jsarticle}

\bibliographystyle{jplain}
\title{p\LaTeX\ 実験}
\author{林蓮枝}

\begin{document}

\maketitle

\begin{abstract}
本稿では、文書組版システムp\LaTeX{}の使い方を解説します。p\LaTeX{}を利用するときには、あらかじめ文章中に\TeX{}コマンドと呼ばれる組版用の指示を混在させ\ldots
\end{abstract}

\section{導入}
こんにちは世界！

\end{document}
  2. If you are uploading a .tex file from elsewhere, make sure it is saved in UTF-8 encoding.
  3. In the Overleaf editor, click on the Overleaf menu button above the file list panel.
  4. Set the "Compiler" option to "LaTeX".
  5. Add a blank file to your project, and save it as latexmkrc.
  6. Add the following line to your latexmkrc file:
    7. $latex = 'platex';
$bibtex = 'pbibtex';
$dvipdf = 'dvipdfmx %O -o %D %S';

Use the link below the following code listing to open an Overleaf project which creates a suitable latexmkrc file and typesets the LaTeX code.

main.tex

\documentclass{jsarticle}

\end{document}

latexmkrc

$latex = 'platex';
$bibtex = 'pbibtex';
$dvipdf = 'dvipdfmx %O -o %D %S';

 Open this example in Overleaf.

This example produces the following output:
