Abe is expected to meet with Trump in Washington on February 10. He said Japan would again explain to the US side its unprecedented monetary easing policies, which have pulled the yen lower against the dollar in recent years.
"The criticism that our policies are intended to direct the yen lower is undeserved," Abe told fellow lawmakers.
Instead they are aimed at spurring inflation, he said. During a meeting with pharmaceutical executives yesterday, Trump complained about drug makers shifting production overseas and said his trade policies would end unfair "global freeloading," according to a transcript of the meeting.
Trump occasionally has railed against Japan's trade surplus with the US, which fell 4.6 per cent last year from a year earlier to USD 60.2 billion, according to preliminary Japanese trade figures.

The yen's value fell steadily after Japan's central bank implemented massive monetary easing four years ago, hoping to counter deflation and get people and businesses to spend more money.
Trump is not the only critic of that trend toward a weaker yen. But Japan generally has won grudging acceptance of its unorthodox monetary policies from its major trading partners.
The dollar was trading near 100 yen in August but has surged recently, partly because the Federal Reserve is gradually raising interest rates and partly because investors are betting on bigger returns from investments under Trump's administration.
Trump also singled out China's currency. For many years, U.S. Officials complained that Beijing was keeping the yuan artificially low to make its products more competitive in overseas markets. But more recently, Chinese regulators have been striving to prevent the currency from weakening too quickly.
There was no immediate reaction to Trump's comments from Beijing, where financial markets and government offices are closed this week for lunar new year holidays.
