The Bank of Japan (BOJ) has expanded their purchase of YEN, hoping to overtun the deflation. As a consequence, the Yen is devalued.
The exports have boosted, but in the same time prices of imports have increased, especially for commodities.
A simple look at US equity markets indicates a possibility for further price increase. According to the Bank of Japan chief, Haruhiko Kuroda, the BOJ will continue easing to achieve 2% price target.
