Ongoing weakness in the yen has jolted DBJP and DXJ over the past three months. Even with Thursday’s losses, DBJP is up about 9.2% over that time while DXJ has added 6.4%.

The WisdomTree Japan Hedged Small Cap Fund (NasdaqGS: DXJS), which debuted in late June 2013 as DXJ’s small-cap equivalent, is up 7% over the past three months. That ETF already has $48 million in assets. In local currency terms, Japanese stocks surged 56.7% last year, making Japan the best-performing developed market in the world, according to Bespoke Investment Group.
