A roundup that captures Japan at two speeds right now. On one track, markets are hitting records and major industrial partnerships are forming — Sony and TSMC linking up on image sensors for automotive and robotics, two XR/medtech startups closing funding rounds, and a broader AI tailwind lifting equities across the region. On the other track, Typhoon 6 is a grinding logistical crisis: hundreds of flights cancelled, Shinkansen potentially halted, and linear rainbands threatening southern Kyushu with rapid-onset flooding danger. Meanwhile the Shizuoka chapter of the Linear Shinkansen saga is entering what sounds like a final act — JR Tokai finally doing in-person briefings with residents after years of tension over water and environmental concerns. That’s a meaningful shift in posture from the company.
