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 on record. This surge in overseas investment was fueled by improvements in capital efficiency among Japanese companies and robust performance from a wide range of chip-related firms benefiting from the artificial intelligence boom [1].
The Nikkei Stock Average has climbed 39% since the end of 2025, significantly outpacing gains in the STOXX 600 and S&P 500. This rally is attributed to Japan's strong presence in AI and niche technology sectors, which has attracted substantial foreign capital. Market analysts attribute the unprecedented net buying to growing confidence in Japan’s corporate governance reforms and its critical role in the global technology supply chain [1].
Market participants express optimism, with one Tokyo-based analyst stating, "Japan’s equity market is increasingly seen as a prime destination for global investors, especially with advancements in capital efficiency and the AI sector." Technical analysis shows the Nikkei Stock Average has established new support levels after its 39% rally, with resistance levels being tested as the index nears historic highs. Continued upward momentum is anticipated if chip-related and AI stocks maintain their outperformance [1].
Traders are advised to closely monitor key price levels and the performance of leading AI and semiconductor companies, as bullish sentiment prevails. The broad participation of foreign investors suggests sustained upward pressure on Japanese equities, though increased volatility is possible due to profit-taking and sector rotation [1].
CONCLUSION
Record-breaking foreign inflows and a 39% rally in the Nikkei highlight strong global investor confidence in Japan’s equity market, driven by AI and semiconductor growth. Market sentiment remains bullish, with expectations for continued gains if sector leaders sustain their momentum. However, traders should remain vigilant for potential volatility as the market tests new highs.
