Yes, zw is a pTeX only dimension with the width/height of
the boxsize of a ideographic char. You could define your own
version in TeX with:

\newdimen\zw

\def\KAN#1#2#3#4#5#6{%
\setbox0=\hbox{　}% ideographic space
\zw=\wd0
...
\ifdim\wd0>.6\zw
   \ifdim11pt>\zw
     \OYA=17pt
   \else
     \OYA=1.6zw
   \fi
\else
...
}

I used the simpler kanbun.sty file as example.

Another things you have to do are to change the encoding of
the file to UTF-8 and to replace ¥ with \.
