Koji Arima

Koji Arima serves as President and CEO of Denso Corporation, the world's second-largest automotive components supplier after Bosch. Denso was originally Toyota Motor's parts manufacturing division, spun off in 1949, and remains deeply intertwined with Toyota — which holds approximately 25% of Denso's shares and accounts for roughly half of its revenue. However, Denso now supplies virtually every major automaker globally, with annual revenues exceeding $50 billion. Denso's product portfolio spans the full breadth of automotive technology: thermal management (air conditioning, engine cooling — Denso is the global leader), powertrain components (fuel injection systems, engine management), electrification systems (inverters, motor generators, battery management for EVs and hybrids), advanced driver assistance systems (ADAS — LiDAR, radar, vision sensors), and semiconductor solutions (Denso designs and manufactures automotive chips, a critical capability given the industry's chip shortage experience). The company faces a transformational challenge: pivoting from its traditional strength in internal combustion engine components (which will gradually decline) toward electrification, autonomous driving, and connected vehicle technologies (which are growing rapidly). Key stock drivers include global vehicle production volumes, Toyota's production plans, the pace of vehicle electrification (particularly hybrid and BEV adoption), ADAS penetration rates, automotive semiconductor demand, yen exchange rate movements, and the competitive dynamics against Bosch, Continental, and ZF Friedrichshafen.
