June 23 (Reuters) - Asian shares edged up and sterling stood close to its peak for the year on Thursday, as investors were cautiously optimistic that British voters would opt to remain in the European Union at a referendum later in the session.
Two opinion polls published late on Wednesday, a few hours before voters were due to begin to cast their votes, showed the "Remain" camp gaining momentum in the closely divided campaign.
MSCI's broadest index of Asia-Pacific shares outside Japan edged up 0.2 percent in early trading, shrugging off modest overnight losses on Wall Street.
Japan's Nikkei share average rose 0.3 percent.
"Markets seem to have almost entirely priced in a 'Remain' vote win, meaning that the market moves and volatility around the vote may be far less than many had been expected," wrote Angus Nicholson, market analyst at IG in Melbourne.
"Nonetheless, markets are still incredibly nervous and some sharp market moves are likely over the next 24 hours," he said.
