My concern is that the most of Japanese screen readers can't provide
these kinds of context. I'm wondering if the screen readers in the
other languages than English also can associate the link text with
these context.

The WG would say that it is an user agent issue?? If so, the reality
is that the Japanese users would be confused with the multiple links
on a web page such as "Here!", "Click here!" and so on. JIS doesn't
allow the authors to use such link text. For the Japanese users, I'd
like to remove 2.4.4 and move 2.4.8 to L2.
