* Fed's view on economy, exit strategy provide relief
* Kawasaki Heavy, train makers surge on Vietnam train report
* Market trend upward but investors still cautious

TOKYO, Aug 13 (Reuters) - Japan's Nikkei average rose 0.7 percent on Thursday, lifted by exporters such as Advantest Corp <6857.T>, with investors relieved after the Federal Reserve suggested the U.S. economy is through the worst of the recession.
Kawasaki Heavy <7012.T>, which makes railway rolling stock, and other companies involved in making trains surged on a report that Vietnam will use Japan's bullet train technology in building its high-speed railway system.
Market players said the market welcomed few surprises in the Fed's closely watched exit strategy, in which it will continue to stick to its current measures, but added that trade remained cautious.
"Market sentiment has warmed up but it is not as if investors are gung-ho bullish. They are still a bit jittery," said Junichi Misawa, senior fund manager at STB Asset Management.
"Stocks appear to be overvalued considering the current level of corporate earnings but I believe that sentiment as it is right now is indicative of a long-lasting run-up."
The Fed said the economy was levelling out, and it left interest rates unchanged at the end of its two-day policy meeting on Wednesday.
It also said it would extend by one month through October the duration of a programme to buy long-term government securities but would not increase the amount of purchases. [
