TOKYO -- Asian equity markets ended mixed Thursday, as investors in Japan stepped in to buy some oversold technology stocks, but in South Korea and Taiwan tech shares continued tumbling lower.

In Tokyo, the

Nikkei 225

closed up 37.1, or 0.2%, to 15,550.7. But the

Topix

index, which includes all shares listed on the

Tokyo Stock Exchange

, fell 5.7, or 0.4%, to 1454.1, as sentiment remained cautious following a poor close by Wall Street Wednesday.

Technology shares that have taken a beating over the past couple of days rebounded with a vengeance. Chipmaker

NEC

(NIPNY)

, which fell 5.3% on Wednesday, surged 110 yen, or 5.1%, to 2,160 ($20.07) and

Fujitsu

, which dropped 5.2% Wednesday, rose 65 yen, or 3%, to 2,270.

(NTT)

fell 40,000 yen, or 3.6%, to 1.08 million and wireless operator

Kospi

index ended down 22.5, or a further 4%, to 534.7.

Taiwan's

TWSE

index fell 235.5, or 3.9%, to 5805.0, as big chipmakers continued to feel the pain and the government reinstated the market's normal limit for a maximum 7% fall per day. Hong Kong's
