Nov. 10 (Bloomberg) -- Japanese stocks advanced, extending a rally in U.S. equity and commodity markets after the Group of 20 nations agreed to maintain economic stimulus efforts.

Mitsubishi Corp., Japan’s second-biggest trading company, increased 1.8 percent after oil, gold and metals climbed. Sumitomo Metal Mining Co., a producer of non-ferrous metals, advanced 1.7 percent. Sumitomo Mitsui Financial Group Inc., a bank, added 1.3 percent. Hoya Corp. gained 1.6 percent after Japan’s largest maker of optical glass was lifted to “buy” from “underperform” at Merrill Lynch & Co.

The Nikkei 225 Stock Average rose 0.9 percent to 9,900.23 as of 9:05 a.m. in Tokyo. The broader Topix index increased 0.8 percent to 877.18.

“Exporters as well as financial stocks should lead the market higher after the climb in the U.S. stock market following the G-20 agreement,” said Fumiyuki Nakanishi, a strategist at Tokyo-based SMBC Friend Securities Co. “A rise in gold futures will lure investors and gold-related stocks will be bought.”

In New York, the Standard & Poor’s 500 Index advanced 2.2 percent yesterday for its sixth straight increase, led by financial companies.

Gold futures for December delivery added 0.5 percent to $1,101.40 an ounce on the New York Mercantile Exchange’s Comex division yesterday after reaching a record $1,111.70 earlier. Crude oil for December delivery increased 2.6 percent to $79.43 a barrel in New York. The London Metals Index, a measure of six metals including copper and zinc, gained 0.9 percent.
