Foreign investors purchased a net 9.7 trillion yen ($60 billion) in Japanese stocks during the first half of 2026, marking the highest half-year inflow ever recorded. This surge in overseas investment has been fueled by improvements in capital efficiency and a robust base of chip-related companies that are benefiting from the ongoing artificial intelligence boom [1].
The Nikkei Stock Average has climbed 39% since the end of 2025, significantly outperforming the STOXX 600 and S&P 500, which have seen much smaller gains in the same period. This exceptional performance is attributed to a combination of corporate governance reforms and a renewed focus among Japanese companies on shareholder returns and capital efficiency [1].
Market analysts highlight that the influx of foreign capital reflects global investors' desire for exposure to Japan’s dynamic equity market, particularly in AI and semiconductor sectors. A Tokyo-based analyst described capital efficiency improvements as a 'real game-changer for foreign investors,' while a London market strategist emphasized the foundational role of Japan’s chip-related companies in supporting the AI boom [1].
Technical analysis indicates that the Nikkei’s strong upward momentum is underpinned by higher trading volumes and bullish moving averages. Analysts recommend monitoring key price levels for the Nikkei Stock Average, with support near previous highs and resistance at new record levels. They also advise investors to watch for further gains in Japanese equities, especially among AI and semiconductor-related stocks, as ongoing governance reforms and capital efficiency improvements could sustain the rally [1].
CONCLUSION
Japanese equities have attracted unprecedented foreign investment in the first half of 2026, driven by structural reforms and a thriving technology sector. With the Nikkei Stock Average outperforming global peers and analysts optimistic about continued gains, Japan stands out as a leading market for international investors.
