Spurred by "Abenomics" and a weaker yen, the Nikkei 225 index is outpacing its peers this year by a wide margin. Some stocks are posting gains of 60%, 70% or even 100%. Here are a few of the top performers.
Shares of Yokohama Rubber have more than doubled since January, making it one of the Nikkei's hottest stocks.
While some particularly successful outliers have boosted the Nikkei's average, the index is up a whopping 34% this year.
Over the same time period, the Shanghai Composite is down 3% and the Hang Seng has declined 1%. The Australia ASX All Ordinaries is up 9%.
