On the 4th of June, on the occasion of cases filed in 2003  [en] and in 2005 whose protagonists were 10 children born out of wedlock to Japanese fathers and Filipino mothers, the Supreme Court declared unconstitutional an article of the Nationality Law [en] because it infringes on Article 14 of the Constitution  [en], which grants the right to equality. According to the article, while a child born in wedlock to a Japanese father and a foreign mother is in every respect recognized as a Japanese citizen, before the June 4th decision children born out of wedlock were only recognized as Japanese citizens if paternity had been confirmed before the child's birth.
id:Inflorescencia  at her blog describes, through the use of pictures, details of the Nationality Law and the process that brought about its revision.
On the 18th of November, after this historical ruling by the Supreme Court, a bill  [jp] was passed by the House of Representatives to amend Article 3 of the Nationality Law. However, while the enactment of the bill by the House of Councilors is expected by the 30th of November, many voices have been raised in opposition to it .
Responding to these protests, Hideo Ogura at la_causette  posted an entry titled: “Opposing to the revision of the Nationality Law, Clause 1, Article 3 is a waste of energy” (国籍法３条１項の改正に反対することはエネルギーの無駄である). In it he refers to the nationalist movement born on the Internet which opposes the decision of the the Supreme Court [en] and the subsequent amendment of the Law.
To me this is nothing but a waste of energy. Because even if they managed to block the mentioned revision, it wouldn't bring about the society that these people are hope for.
Plus this bunch of people who are trying to pile useless work on the State just for the sake of xenophobia, who pretend to be called “patriots”, perplex me very much indeed.
