Links to Japanese version of the Subversion book dead?

Hi,

I'm looking for the Japanese translation of the Subversion book.

The links to the single and multi-page versions on the "cover page"[1]
appear to lead nowhere these days.

 [1] http://svnbook.red-bean.com/index.ja.html[1]

Googling a bit, what I've found so far are translations for 1.5 (final)
and 1.7 (WIP) at what appears to be a personal site[2] but its
maintenance state does not look very promising. Then there is also a
version[3] at the University of Tokyo dated 2006-02-03.

 [2] http://www.caldron.jp/~nabetaro/svn/[2]
 [3] http://todo.issp.u-tokyo.ac.jp/archive/subversion/book.html[3]

Is there any chance of getting the Japanese "cover page"[1] to point to
up to date versions of the single and multi-page versions of the book?
Should I submit a ticket for this?

Thanks in advance,
