The problem is here:

\newcommand*{\rubystack}[2]{%
   \begin{tabular}[b]{@{}c@{}}%
     {\tiny#1}\\%
     {\normalsize#2}%
   \end{tabular}%
}

In the first row you are putting \tiny content into
a \normalsize row of text, since by default you will be
using this tabular within a normal paragraph.

Thus you seem to have a lot of extra space, since
the tiny ruby doesn't fill out the full amount
that the \baselineskip is set to, when the \\ is
encountered at the end of that first row.

Here's a way to fix that:

\newcommand*{\rubystack}[2]{{\tiny
   \begin{tabular}[b]{@{}c@{}}%
     {\tiny#1}\\%
     {\normalsize#2}%
   \end{tabular}}%
}

Now the \baselineskip for the 1st row is set by the first \tiny .
while the \normalsize in the 2nd row forces expands that row's height
to accommodate its content.

The image shows what I get, with boxes indicating the space allocated
where I don't have your CJK font installed.

Hope this helps,
