Tokyo - Markets across Asia plummeted on opening Thursday, dragged down by US retail sales data and concerns about whether bank bail-outs would be able to rescue financial markets and avert a recession.

The Tokyo stock market plummeted in early trading after Wall Street's blue-chip Dow Jones industrials lost nearly 8 per cent overnight amid growing recession fears in the United States and worldwide.

The benchmark Nikkei 225 Stock Average plunged 911.91 points, or 9.55 per cent, to 8,635.56.

After stocks fell, Japan's central bank injected 600 billion yen (5.92 billion dollars) into money markets to ease the credit crunch that has resulted from the global financial crisis.

Hong Kong's Hang Seng Index opened more than 6 per cent lower. The blue-chip index, which lost 5 per cent of its value Wednesday, was down a further 6.11 per cent at 15,020.75 within 20 minutes of the start of trading.

Taiwan's Taiex index traded 3.14 per cent lower in the morning at 5,081.69, dampened by Wall Street woes and the death of Wang Yung-ching, founder of Taiwan's petrochemical giant Formosa Group, dealers said.

Stocks of all six listed companies of the Formosa Group fell sharply on the death of the group founder, dubbed the "god of management" and the second-wealthiest man in Taiwan.

Investors fled Australian stocks in response to Wall Street registering its biggest one-day percentage loss in 20 years.
