Japan M&A By the Numbers: Q4 2025

The M&A landscape rebounded robustly in 2025, thanks to supportive economic fundamentals and rising confidence among businesses. In Japan, domestic portfolio reshuffling, pressure from shareholders, and plans for strategic global growth have spurred M&A activity.​​
