According to the wikistats page
(
http://www.wikipedia.org/wikistats/EN/Sitemap.htm in English), Japanese
(ja:) is the 3rd-largest Wikipedia, after English and German, both in
terms of articles and in terms of active contributors. I haven't really
heard any discussion from there though---there's plenty of people from
the de:, fr:, and even lots of smaller Wikipedias here, but not many at
all from ja: that I've heard of. Anyone know how things are going on
over there? Do they know about the Wikimedia Foundation and have any
interest in it or requests or concerns or whatnot?
