TOKYO (AFP) - Tokyo stocks opened 0.84 per cent weaker on Thursday, retreating after a downturn on Wall Street and as the yen rose against the dollar.

The Nikkei 225 index fell 127.33 points to 14,942.15 at the start of the session.

"The market continues to look top-heavy at 15,000, and will consolidate, pushed down by the dollar's weakness," said SMBC Nikko Securities general manager of equities Hiroichi Nishi.

The Dow Jones Industrial Average on Wednesday snapped a four-day streak of record highs as profit-taking took hold, closing down 0.60 per cent to 16,843.88.

The losses also came after the World Bank trimmed its 2014 global growth forecast to 2.8 per cent from its January forecast of 3.2 per cent.

The dollar was at 101.99 yen in early Asian trade Thursday, hardly changed from 102.03 yen in New York Wednesday afternoon but down from 102.27 yen in Tokyo earlier Wednesday.

The euro bought US$1.3536 and 138.07 yen against US$1.3532 and 138.06 yen in US trade.
