The dollar remained steady against the yen in Asia trade Wednesday after hitting Y123.33, its highest level in nearly eight years.

Around 0450 GMT, the U.S. currency was at Y123.11 almost unchanged from Y123.10 late Tuesday in New York.

The greenback held on to its gains overnight that followed U.S. data showing improved business investment, housing market and consumer confidence. After a bout of selling on profit taking, the dollar managed to recoup these losses and extended gains in mid-morning, with Japanese corporate investors placing dollar buying orders related to commercial trade settlement ahead of the end of the month. It then hovered above the Y123-line with no clear direction for the rest of the Asia session.

"There has been a distinct difference in the dollar-yen pair trade between when it moves and when it doesn't," said Mizuho Securities chief FX strategist Kengo Suzuki. "Once it starts moving, investors are jumping on the story, thus persistently preventing it from falling," said Mr. Suzuki.

In addition, Mr. Suzuki said comments by Japan's Chief Cabinet Secretary Yoshihide Suga put investors cautious about jawboning from U.S. and Japan authorities at ease.

Mr. Suga reiterated earlier Wednesday that he doesn't see the current foreign exchange moves as rapid.

Still, some contend the dollar's rally against the yen since yesterday came without an uptick in U.S. Treasury yields, which is something that is difficult to explain.

The dollar's upswing contradicts a recent narrowing of the gap between U.S. and Japan bond yields, in a possible indication that the pair's latest rally is "flow driven and only temporary," J.P. Morgan said in a morning note.

Investors remained skeptical about the timeframe of the Federal Reserve's decision to raise short-term interest rates, given a soft patch in the U.S. economy since the January-March quarter.

But a string of encouraging signs on the U.S. economy together with Fed Chairwoman Janet Yellen reminded investors of the Fed's rate increase, long before rival central banks. In fact, Ms. Yellen said Friday the central bank is on track to raise interest rates sometime this year.

On Tuesday, Richmond Federal Reserve Bank President Jeffrey Lacker said he still hasn't decided whether to vote for an interest-rate increase at the central bank's June 16-17 meeting.

"I haven't made up my mind yet about June," he told reporters after a speech. "I am going to wait and see what the data reveals."

Among other currency pairs, the euro was at $1.0889 from $1.0872, while the common currency was at Y134.03 from Y133.85.

The WSJ Dollar Index, a measure of the dollar against a basket of major currencies, was down 0.09% at 87.11.
