TOKYO (Reuters) - Asian shares edged up to one-year highs on Friday as investors lapped up signs of improving momentum in the world's biggest economies, with Tokyo's Nikkei poised to score its first weekly gain in over a month thanks to a weaker yen.
The improved risk appetite nudged U.S. debt yields higher and supported the dollar, which is on track to notch its first weekly gain against the yen since April.
Asian equities rode the momentum set in motion the previous session by surveys showing China's factory sector had its best performance in five months in May and U.S. factory output growth hitting its fastest pace since February 2011.
Separately, data showed U.S. home resales rose in April and the supply of properties on the market hit its highest level in nearly two years, promising signs for the housing market.
The confluence of positive data from the world's biggest economies soothed investor nerves though uncertainty over China's outlook is likely to keep markets on edge this year.

A partial distraction for regional investors came from another day of tension in Thailand's long drawn out political crisis, with the military on Thursday seizing power in a bloodless coup.

Meanwhile, presidential elections in Ukraine on Sunday is another potential development that could undermine investor risk appetite. The United States and European Union hope the vote will strengthen the embattled central government.
"If elections are not held in all parts of Ukraine, Russia could further question the legitimacy of the process, and this would increase geopolitical risk," said Masafumi Yamamoto, market strategist at Praevidentia Strategy in Tokyo.
The Nikkei .N225 climbed 1 percent as the yen remained on the back foot against the dollar. The Japanese index has gained about 2.6 percent so far this week.
The dollar traded little changed at 101.77 yen, and has gained about 0.2 percent on the week. Though the gains are modest, it is still poised to snap a four-week losing run versus the yen, helped as U.S debt yields bounced from multi-month lows this week.
