Still, the domestic focus is paying off today, as a surging yen weighs on exporters and sends the market lower. Shiozumi’s pound-denominated fund has returned 37 percent this year, while the Topix index is down 13 percent in yen terms and less than 1 percent in pounds. Over a five-year period, he’s beating 98 percent of peers. In the first quarter of 2016, about 60 million pounds ($87 million) flowed into the fund, which gets all its money from overseas, even as many foreign investors fled Japan. Shiozumi says if it gets much bigger he’ll stop accepting investments.
