Prime Minister Shinzo Abe told Wall Street on Wednesday that alongside his push for deregulation and empowering women to spur the economy, Japan will contribute to nuclear safety technology by overcoming the Fukushima crisis.

Abe also said Japan, together with the U.S., should lead multilateral efforts toward concluding the Trans-Pacific Partnership by the end of this year.

"Buy my 'Abenomics,' " he said in a speech delivered at the New York Stock Exchange, touting the measures he has taken since assuming power in December to jump-start an economy mired for decades in deflation and repeated recessions.
