iShares MSCI Japan ETF (NYSEARCA:EWJ) is the default way for American investors to gain exposure to Japan. EWJ tracks the MSCI Japan Index, holds hundreds of Japanese large- and mid-cap companies including Toyota, Sony, and Mitsubishi UFJ, and manages roughly $15 billion in assets. It is cheap, liquid, and diversified. That is why it sits in so many portfolios as the “Japan sleeve.” The problem is that EWJ carries something most holders forget they own: the Japanese yen. A currency-hedged alternative has quietly captured more of the Nikkei’s 2026 rally, and the gap is larger than the title suggests.
Why EWJ Underperforms When the Yen Slides
EWJ holds Japanese stocks priced in yen, then reports its NAV in dollars. When the yen weakens against the dollar, EWJ’s shares are worth fewer dollars, even if the underlying stocks rally in Tokyo. That is exactly what has happened this year. The yen weakened significantly against the dollar throughout the first half of 2026, creating a currency headwind for U.S. investors holding unhedged exposure to Japan. Japanese equities rose, but a chunk of the gain was eaten by the currency translation.
The numbers show it clearly. EWJ returned 15.23% year-to-date through July 8 on an adjusted basis. That is a solid figure in isolation. The issue is that the yen-hedged version of the same trade returned considerably more. Over the past year, EWJ is up 31.92%, which again looks strong until you compare it to what a hedged wrapper produced over the same window.
EWJ’s expense ratio is 0.49%, and its dividend yield sits near 3.86%. Those are fine on their own. The shortfall traces back to the fund’s unmanaged yen exposure.
DXJ: The Same Japan Trade, Without the Currency Drag
The alternative is the WisdomTree Japan Hedged Equity Fund (NYSEARCA:DXJ). DXJ owns dividend-paying Japanese exporters and layers on forward currency contracts that neutralize yen moves against the dollar. When the yen falls, DXJ holders keep the equity gain. When the yen rises, they give up that tailwind. It is a deliberate bet that the equity exposure is the target and the currency exposure is noise to remove.
Through the first six months of 2026, that structure paid off. DXJ returned 21.49% year-to-date, roughly six percentage points ahead of EWJ over the same period. Over a longer horizon, the gap widens. Over one year, DXJ is up 54.17% against EWJ’s 31.92%. Over five years, DXJ has returned 228.07% compared with EWJ’s 52.43%. The bulk of that spread traces back to a decade in which the yen weakened from the 100s into the 160s while the Nikkei climbed.
DXJ also tilts toward exporters like automakers and industrials, companies that benefit operationally from a weaker yen because their overseas revenue converts into more yen. So the fund captures the equity upside from a soft yen, while the hedge offsets what a US investor would otherwise lose due to currency translation. Morningstar’s 2026 outlook flags this dynamic directly, noting that yen hedging costs are near 4% per year due to the wide gap between US and Japanese short-term rates. That is the toll DXJ pays. When the yen falls by more than the carry cost, the hedge is a net win. That is what has happened.
The Tradeoffs Worth Naming
DXJ is a directional call, and if the yen strengthens sharply, either from a surprise Bank of Japan rate hike or a broader dollar retreat, DXJ will lag EWJ, and the hedging carry cost will erode returns each year, regardless of currency direction. JPMorgan’s 2026 outlook notes that the dollar is still roughly 10% overvalued relative to fair value, which is the scenario in which EWJ would claw back its gap.
Composition differs between the two funds as well. EWJ is more diversified across sectors and includes domestic-facing financials such as Mitsubishi UFJ at 4.1% and Toyota at 4.3%. DXJ concentrates on dividend-paying exporters, which is why it tends to move more sharply in both directions.
Sizing the Swap
For a taxable account, a full swap after a 15%+ YTD run in EWJ would likely realize capital gains. A partial rotation, or directing new contributions into DXJ while leaving existing EWJ shares in place, sidesteps the tax event and still shifts the currency profile of the sleeve. Within an IRA or 401(k) brokerage window, the tax question disappears, and a direct swap is mechanically simple.
The decision reduces to a view on the yen. A hedged wrapper has been the better vehicle for capturing Japan’s rally in 2026, and the multi-year data support that call while the rate differential persists. If the view flips, so does the math.
