Japan faces a structural labor crisis: 29% of population over 65, 570K care worker shortage by 2040, unemployment at 2.5%. Government reframing robotics from 'industrial automation' to 'physical AI' in 2026. Japan pursues a component-excellence strategy: Harmonic Drive, Nabtesco, and Yaskawa supply ALL humanoid OEMs globally. Global humanoid market: 50K-100K shipments expected in 2026, unit costs converging on $15-20K. SoftBank acquiring ABB Robotics for ~$5.4B. NEW: SoftBank/NEC/Sony/Honda founded '日本AI基盤モデル開発' (Apr 13, 2026) — 1T-parameter Physical AI foundation model. NVIDIA GTC 2026 named Fanuc+Yaskawa in 'Big Four' Physical AI partners. METI targeting 30% global Physical AI market share by 2040. Government ¥1T over 5 years for domestic AI foundation model development.
