世論 What Japan Thinks

This survey by Media Interactive, reported on by japan.internet.com, into Q&A sites found that most people find them reliable enough.

Demographics

Between the 2nd and 4th of February 2010 1,000 members of the Media Interactive monitor group who had used or even just viewed Q&A sites completed a private internet-based questionnaire. 51.4% of the sample were male, 1.3% in their teens, 17.6% in their twenties, 32.9% in their thirties, 29.0% in their forties, 15.0% in their fifties, and 4.2% in their sixties.

I did use Yahoo! Answers in English for a bit, both asking and answering, but… The answers were mostly OK, but auite often I’d see incorrect information being promoted, making it even worse than Wikipedia for reliability.
