Tokyo - Japan's benchmark Nikkei 225 Stock Average gave up early gains Thursday to end at a five-year low as concerns lingered over the global financial crisis.
The key Nikkei index fell 45.83 points, or 0.5 per cent, to close at 9,157.49.
But the broader Topix index of all first-section issues went up 6.1 points, or 0.68 per cent, to 905.11, a day after nine central banks lowered interest rates.
The Bank of Japan injected a record 4 trillion yen (39.8 billion dollars) into the money markets Thursday amid escalating concerns over the financial crisis.
