The Nikkei 225 index at the Tokyo Stock Exchange was down 26.57 points at 12,371.34 at the start on Monday.

The figures, which marked a modest uptick in confidence, showed large manufacturers' sentiment improve to minus 8 between January and March from minus 12 three months earlier. New investment money will start flowing into stocks from Monday as a new fiscal year starts, noted SMBC Nikko Securities general manager of equities Hiroichi Nishi. "But turmoil in the eurozone regarding the Cyprus bank fallout, as well as geopolitical stress in the Korean peninsula still warrant keen attention," he added.
