TOKYO, April 22 (Reuters) - Japanese shares fell on Friday, tracking Wall Street's overnight weakness after Federal Reserve Chairman Jerome Powell suggested the U.S. central bank would move aggressively to curb inflation.

By 0219 GMT, the Nikkei share average had fallen 1.9% to 27,025.18 and the broader Topix was down 1.33% at 1,902.40 after three straight sessions of gains, with technology and growth stocks leading the retreat.

For the week, the Nikkei was down 0.2%, while the Topix was up 0.32%.

Wall Street ended lower overnight, with the Nasdaq dropping more than 2%, as investors reacted to Fed officials including Powell dropping hints of a half-point interest rate increase.

"The Japanese market reacted too much. Investors should have already factored in rising U.S. interest rates," said Jun Morita, general manager of the research department at Chibagin Asset Management.

"On the other hand, it is hard to make positive bids before the corporate earnings season kicks off."

Chip-making equipment maker Tokyo Electron led declines on the Nikkei, falling 3.25%. Uniqlo clothing shop operator Fast Retailing lost 2.7% and technology investor SoftBank Group dropped 3.26%.
