TOKYO, Feb 18 (Reuters) - Japan's Nikkei index rose on Wednesday, snapping a four-day losing streak, with shares of technology companies expected to take part in a $550 billion Japanese-funded investment project in the United States climbing.

The Nikkei index rose 1 percent to 57,131.89 points by 0135 GMT, while the broader Topix index climbed 1.35 percent to 3,812.39 points.

The administration of US President Donald Trump announced on Tuesday three projects funded by Japan worth $36 billion: an oil export facility in Texas, a synthetic diamond factory in Georgia, and a natural gas-fired power plant in Ohio.

These projects will be the first investments under Japan’s pledge to inject $550 billion into the United States as part of a trade agreement aimed at reducing U.S. tariffs on Japanese imports to 15 percent.

"Investors have been snapping up shares linked to the Trump deal over the past few days," said Takamasa Ikeda, senior portfolio manager at GCI Asset Management.
