Tokyo stocks end flat as strong yen pares Fed rally

Tokyo stocks ended flat Thursday as a strong yen pared early gains that have driven Federal Reserve boss Janet Yellen's suggestion that US interest rates could rise gradually.

Japanese traders tracked a Wall Street record in the first few hours after Yellen told Congress the central bank would keep lifting rates as long as the US showed improvement, taking into account inflation remained below its two percent target.

Her remarks fuelled optimism that borrowing costs in the world's top economy would stay low for some time.

However, stocks reversed course in the afternoon as dealers moved out of the dollar, sending the yen higher, which in turn dragged on Japan's exporters.

The dollar was changing hands at 113.15 yen in Tokyo, little changed from New York, but well off the 113.50 yen levels seen earlier Wednesday in Asia.
"It's about weighing which will have a greater impact," said Masahiro Ichikawa, a senior strategist at Sumitomo Mitsui Asset Management.
"A cautious approach on rate hikes shouldn't be bad for the overall stock market, but since the yen can't really head lower, it'll be hard for investors to anticipate extra tailwinds from currency moves," he told Bloomberg News.
A strong yen erodes the profits of Japanese exporters and hits demand for their shares.
