TOKYO, Feb 29 (Reuters) - Japanese stocks fell over 2 percent on Friday to their lowest level in a week, with Honda Motor <7267.T> and other exporters battered as the dollar touched a three-year low against the yen.
Growing worries about the U.S. economy weighed on Tokyo shares after Federal Reserve Chairman Ben Bernanke warned about the health of small U.S. banks, hurting financial shares such as Mizuho Financial Group <8411.T>.
Investors were wary ahead of important U.S. economic data due out next week, including employment figures seen as critical in determining the health of the economy.
"People are waiting for the indicators next week and nobody really wants to bargain-hunt given the current environment," said Mitsushige Akino, chief fund manager at Ichiyoshi Investment Management Co Ltd.
"If the ISM (manufacturing index) and jobs figures come in weak, that would move closer to confirming a recession and would be pretty ugly for stocks."
Many market players said Tokyo stocks were pushed up earlier this week on little more than blind optimism and short-covering in the face of a raft of negative factors, and these positions were unwound on Friday.
"What's becoming really obvious is that the market should actually have fallen over the last few days, not risen. What happened was almost like a trick," said Yutaka Miura, a senior technical analyst at Shinko Securities.
"Japanese stocks are being hit with the double punch of U.S. stock falls and the yen's rise against the dollar."
At 0207 GMT the dollar was trading at around 104.66 yen <JPY=> after breaking below the psychologically important 105.00 point in early Tokyo, triggering a wave of stop-loss selling orders that pushed it down to 104.65 yen -- its lowest since May 2005.
The benchmark Nikkei was down 2.5 percent by midsession, shedding 354.19 points to 13,571.32. The broader TOPIX <

Bernanke warned that small banks that had invested heavily in real estate could collapse, renewing fears about a credit squeeze.
Those fears were further fanned after American International Group Inc <AIG.N> posted its biggest-ever quarterly loss on Thursday, hurt by a write-down of derivatives exposed to bad mortgage investments [
].Mizuho Financial Group slid 5 percent to 452,000 yen and Mitsubishi UFJ Financial Group <8306.T> was down 3.7 percent at 950 yen. Sumitomo Mitsui Financial Group <8316.T> fell 4 percent to 773,000 yen.
Property shares tumbled on the gloomy economic outlook, with property developer Mitsubishi Estate <8802.T> down 3.9 percent at 2,625 yen and Mitsui Fudosan <8801.T> down 4.2 percent at 2,185 yen.
The property subindex <.IRLTY.T> fell 4 percent, the biggest drop among the subindices.
Exporters slid, with Honda down 3.6 percent at 3,240 yen, Sony Corp <6758.T> down 3.5 percent at 5,040 yen, and Toyota Motor Corp <7203.T> down 3.1 percent to 5,730 yen.
One bright spot was Seven Bank Ltd <8410.Q>, whose shares jumped 17 percent in their market debut on Friday following a $483 million IPO as subprime-rattled investors embraced the firm's low-risk model of earning fees from cash machines.
Trade slowed on the Tokyo exchange's first section, with 885 million shares changing hands, compared with last week's morning average of 961 million.
Declining stocks outnumbered advancers by a ratio of nearly 10 to one. (Reporting by Elaine Lies, Editing by Michael Watson)
