Currency-hedged Japan ETF options include the WisdomTree Japan Hedged Equity Fund (NYSEArca: DXJ), iShares Currency Hedged MSCI Japan ETF (NYSEArca: HEWJ) and Deutsche X-trackers MSCI Japan Hedged Equity ETF (NYSEArca: DBJP).

DXJ tries to reflect the performance of the WisdomTree Japan Hedged Equity Index, which tracks dividend-paying Japanese companies that generate the majority of revenue outside of Japan and hedges against a weak yen currency.

HEWJ holds the iShares MSCI Japan ETF (NYSEArca: EWJ) but uses currency swaps to diminish currency risks.

DBJP tries to reflect the performance of the MSCI Japan US Dollar Hedged Index, which also tracks Japanese equities and mitigates exposure to fluctuations between the U.S. dollar and yen.
