TOKYO, June 28 (Xinhua) -- Tokyo stocks closed essentially flat Monday as technology issues losing ground was offset by steelmakers gaining traction, although investors refrained from making bold moves ahead of key economic data.

The 225-issue Nikkei Stock Average shed 18.16 points, or 0.06 percent, from Friday to close the day at 29,048.02.

The broader Topix index of all First Section issues on the Tokyo Stock Exchange, meanwhile, edged up 3.02 points, or 0.15 percent, to finish at 1,965.67.

Local brokers said that investors were keenly eyeing the upcoming release of key economic data including U.S. jobs data as well as the Bank of Japan's (BOJ) Tankan business sentiment survey.

"Some key U.S. economic reports such as jobs data will be released later this week, so inventors will remain cautious for the whole week. But that does not mean sentiment is bad as other indexes have risen," Tomoichiro Kubota, a senior market analyst at Matsui Securities, was quoted as saying.

Other analysts specifically referenced the BOJ's upcoming survey as having a bearing on future market moves.

"Investors refrained from making major moves ahead of the release of major economic data, including the Bank of Japan's Tankan survey later this week," Koichi Fujishiro, a senior economist at the Dai-ichi Life Research Institute, was quoted as saying.
