Stagnant spending and soft wage growth in Japan are forcing two of Asia's biggest retailers — Fast Retailing Co. and Seven & i Holdings Co. — to court overseas consumers to drive long-term growth.

Fast Retailing, operator of the Uniqlo chain, and convenience-store giant Seven & i were set to report earnings results Thursday amid an economy that's still posing challenges even as it expands. While gross domestic product has grown for six straight quarters, wages are still languishing.

Operating profit at Fast Retailing for the fiscal year ending August is expected to increase as the company saw improving results in Southeast Asia and China, and renewed its focus on low prices. Meanwhile, after announcing a broad restructuring of its business that included its biggest international push, Seven & i may report a record operating profit for its second quarter.
