What started out as a mother's online rant about Japan's notorious day care center shortage has evolved into a national movement, galvanizing angry mothers into staging a demonstration and online campaign blasting the government.

Titled "Hoikuen Ochita. Nihon Shine!!! (Didn't Get a Slot in Day Care. Drop Dead, Japan!!!)," the blog post penned by an anonymous mother shed light on the continuing struggle with the day care shortage that has served as a disincentive for mothers to return to work.

The blogger asserted that the failure to address the problem belies Prime Minister Shinzo Abe's vow to "promote dynamic engagement of all citizens," including women.
