Japan's Nikkei share average closed virtually unchanged on Tuesday as foreign buying of exporters and steelmakers was offset by profit-taking on recent gainers such as drug maker Eisai Co. Analysts said the technology sector would probably not react too badly to news after the bell that electronics parts maker Murata Manufacturing Co Ltd had cut its profit forecast for the year to March, citing slow recovery in demand. The Nikkei closed down 0.08 percent at 11,490.43. It hit a four-week closing high on Monday. The TOPIX index of all first-section shares advanced 0.09 percent to 1,155.42.
Large-cap stocks performed even better, with the TOPIX Core 30 index rising 0.68 percent.
