  What is a weak source?  There are links to newspapers like The Japan Times  http://search.japantimes.co.jp/cgi-bin/nn20030918a3.html http://search.japantimes.co.jp/cgi-bin/nn20031106a7.html http://search.japantimes.co.jp/cgi-bin/nn20040409a3.html http://search.japantimes.co.jp/cgi-bin/nn20040415b1.html  Australian Broadcasting Corporation  http://www.abc.net.au/7.30/content/2004/s1120012.htm  Syndey Morning Herald  http://www.smh.com.au/articles/2003/07/04/1057179159324.html  and the Telegraph (UK)  http://www.telegraph.co.uk/news/worldnews/asia/japan/1475762/Student-rape-mastermind-jailed.html  I think there is plenty of reliable resources.  Does Wikipedia need more sources?
