Bernanke speech & subsequent JPY strength

I was reading an article saying that in a Q&A with bernanke, they asked him if he was going to cut interest rates due to low inflation. He said that inflation was above expectations and might increase interest rates. If he is speaking about an increase in the interest rates, then why did the USD lose strength against the JPY?

I'm no pro by any means but maybe the traders don't believe Bernanke. What data has come out of the US that would help the case of raising the rates in the US? Take a look at this weeks calendar. A lot of negative data which is not good for rising rates. In fact the only positives I can find going back a couple of weeks are the non farm employment change and the GDP figure. Other than that I see a lot of negative news.
