DXJ tracks the WisdomTree Japan Hedged Equity Index, which consists of dividend paying Japanese companies that derive the majority of revenue from outside of Japan and hedges against fluctuations in the relative value of the yen against the U.S. dollar.

HEWJ holds iShares MSCI Japan ETF (NYSEArca: EWJ) but hedges against a depreciating yen.

DBJP tries to reflect the performance of the Deutsche X-trackers MSCI Japan Hedged Equity ETF, which also tracks Japanese equities while mitigating the exposure to fluctuations between the value of the USD and the JPY.
