Thank you for your advice.
I asked the maintainer of hyperref package. I'll report the result in this board when he replys my mail.

Hello!
I’d like to ask you about a problem of hyperref with dvipdfmx.
The problem is that hyperlink may involve non-related object.
There’s a source code to show this problem.

\documentclass{article}
\usepackage[dvipdfmx]{hyperref}

\begin{document}

\begin{equation}
x=y \label{eq1}
\end ...
