TOKYO - Tokyo stocks opened 0.80 per cent lower on Tuesday, mirroring losses overnight on Wall Street amid European political and economic uncertainty.

The Nikkei 225 index at the Tokyo Stock Exchange opened down 76.09 points at 9,466.08.

US and European markets were hit by weak eurozone economic data and political turmoil in France and the Netherlands, which rekindled fears about the tenability of the eurozone debt situation, brokers said.

Despite this, Tatsunori Kawai, chief strategist at kabu.com Securities, said Japanese stock market weakness was most likely going to be limited.

"While many investors are clearly sidelined ahead of both US Fed and BoJ policy announcements, the upcoming Golden Week holiday next week is also going to hold participation levels down for the time being," he said.

The US Federal Reserve is to start a two-day policy meeting Tuesday and the Bank of Japan is to hold a one-day meeting on Friday.

The euro fetched $1.3148 (S$1.25) and 106.66 yen, marginally lower from $1.3154 and 106.78 yen in New York late Monday.

The dollar was at 81.09 yen compared with 81.18 yen.

US stocks closed lower but off earlier steep losses due to the uncertainty in Europe and as some US earnings results missed expectations.

The Dow Jones Industrial Average sank 0.78 per cent to finish the trading session at 12,927.17.

The Dutch government collapsed Monday, a day after French President Nicolas Sarkozy lost a first-round presidential vote to Socialist Francois Hollande.
