Tokyo stocks leapt from the bell on Monday as investor sentiment was lifted by solid U.S. jobs data at the end of last week coupled with hopes the government will unroll more stimulus measures after the ruling camp won an upper house election.

As of 9:15 a.m., the 225-issue Nikkei Stock Average jumped 442.03 points, or 2.93 percent, from Friday to 15,549.01.

The broader Topix index of all First Section issues on the Tokyo Stock Exchange, meanwhile, leapt 32.92 points, or 2.72 percent, at 1,242.80.

All industry categories on the main section moved into positive territory, with iron and steel, and machinery issues leading notable early advancers.
