OSAKA -- A library in Fukui Prefecture has become the latest flash point in the struggle over gender equality after it was learned that 150 books on women's issues and gender studies were removed from the shelves.

Last week, it was discovered that the Fukui Prefectural Center for Lifelong Planning in the city of Fukui had removed the books in late March after receiving a complaint from a local resident that the books gave extreme views on gender.

Riyuko Sadaike, head of the center, said there was no political or ideological reason for removing the books. She claimed the books were removed for the staff to investigate if the complaint was valid.
