TOKYO, Feb 5 (Reuters) - Japanese shares rose on Friday, following Wall Street’s rally overnight, as strong earning results of domestic firms and a large U.S. stimulus program boosted market sentiment. Nikkei share average gained 1.06% to 28,641.72 by 0152 GMT, while the broader Topix gained 1.03% to 1,884.38. The S&P 500 and Nasdaq posted record closing highs overnight, as Democrats pushed ahead with U.S. President Joe Biden’s proposed $1.9 trillion stimulus plan without bipartisan support. “A bigger economic stimulus package in the U.S. is good for the global economy and that optimism is lifting economic-sensitive shares in Japan,” said Masahiro Ichikawa, chief market strategist at Sumitomo Mitsui DS Asset Management. “Investors also have started buying the virus-beaten shares ahead of the rollout of COVID-19 vaccines in Japan.” Automakers are leading Nikkei index’s gain, with Mazda Motor jumping 18.52% after the automaker cut its loss forecasts.
