Nikkei closes at highest level since 2007

Tokyo - Tokyo's Nikkei 225 index closed at its highest level in nearly seven years on Friday as the tumbling yen propelled the Japanese market, while investors breathed a sigh of relief over Scotland's vote to stay in the United Kingdom.

The benchmark Nikkei rose 1.58% or 253.60 points, to finish at 16 321.17, its best finish since November 2007 before the global financial crisis, while the Topix index of all first-section shares jumped 1.06%, or 14.00 points, to 1 331.91.

Tokyo's rally followed a positive lead from Wall Street, which saw another record close as investors bet that Scotland would not leave Britain. Later Thursday, the results confirmed that the "No" camp had prevailed.

Sentiment was also lifted by Wednesday's Federal Reserve decision to keep interest rates low and enthusiasm ahead of Chinese e-ecommerce giant Alibaba's expected initial public offering on Friday.

Alibaba priced its stock at $68 on Thursday, setting in motion a record public offering of up to $25bn.

Major Japanese exporters were the key winners as the yen slumped against the dollar, a plus for the firms' profitability.

In currency trading, the greenback was at a six-year high of ¥109.14, compared with ¥108.68 in New York.

"Wall Street, the yen, Scotland - they were all key positive factors today," said Kenzaburo Suwa, strategist at Okasan Securities.

"The market appears to be overheating, but the upward trend is likely to continue for now as investors see not buying shares as a bigger risk."

Investors appeared to shrug off news that Tokyo had in September downgraded its assessment of the economy for the first time in five months, following a string of weak data linked to Japan's April sales tax rise.

"The market is now focusing on what the government will be able to do ahead of a decision later this year on whether to raise the consumption tax (again)," Suwa added.

In Tokyo share trading, Internet and telecom group SoftBank, which has a one-third equity stake in Alibaba, rose 0.57% to ¥8 740.0.

Automaker Toyota was up 0.76% at a one-year high of ¥6,494.0, rival Nissan jumped 1.60% to 1 076.5 yen, while Panasonic gained 0.41%to ¥1 320.0.

Sony, which lost 8.64% on Thursday after warning of ballooning annual loss, fell another 0.97% to ¥1 921.0.
