One of the biggest policy challenges facing Japanese leaders: inflation. They're determined to get it going. They say generating a healthy climate of rising prices is essential for reviving the economy. It's been more than 2 years since Prime Minister Shinzo Abe launched his program to slay deflation. A key objective from the start was to push down the value of the yen. Recent data shows this strategy is having an effect. A weaker yen has pushed up the cost of imports, and that trend is now spreading to other products. I've been talking to retailers and consumers to find out more. One thing I've discovered is that inflation isn't just a case of rising costs. It's actually a new way of thinking.
