Japan's Nikkei share average rose for the 14th session in a row today to post its longest winning streak in over 50 years, as a weaker yen helped stocks recoup earlier losses. 

The Nikkei index opened 0.3% lower but ended 0.04%, or nine points, higher at 21,457.64. That was enough to clinch its longest daily winning streak since 1961. 

For the week, it gained 1.4%, its sixth weekly gain in a row and the longest such winning streak in a year. 

The Nikkei has advanced more than 5% over the past 14 days on hopes that Japanese Prime Minister Shinzo Abe's ruling coalition will win a general election over the weekend. 

Traders said that the market is prone to profit-taking before the election, but the weaker yen, which helps export competitiveness, raised investors' risk appetite on Friday.
