Bloomberg reports that AI-linked firms are rising to the top of Japan’s market-cap rankings, drawing growth-focused funds into a market long viewed as a bastion of value stocks (Bloomberg, June 23, 2026). Kei Takizawa, senior investment strategist at AllianceBernstein Japan, is quoted saying, “We have been raising our exposure to Japan based on the growth prospects of Japanese companies,” and he adds that Japanese firms are taking a larger role in building AI infrastructure (Bloomberg). The coverage notes that renewed global interest after 2023, including Warren Buffett adding trading-house shares and corporate governance reforms, had already shifted narratives around Japan’s cheap valuations (Bloomberg). Reporting also flags the risk of a sharp correction if the AI-driven trend reverses (Bloomberg). Editorial analysis: Industry observers should treat this as a market-structure shift driven by AI-related cap-weight changes, not only by macroeconomic recovery.
