Japan’s automotive aftermarket shows steady growth amid EV adoption and digital shifts. The market evolves with complex vehicles needing advanced diagnostics and telematics, boosted by government EV incentives. We actively engage at IAAE 2026 (Feb 12-14, 2026, Tokyo Big Sight, Booth East H7 7853), showcasing our solutions for local needs. Digitalization and e-commerce platforms further expand independent aftermarket capabilities.
The aftermarket reached USD 32 billion in 2025 and projects a 4.2% CAGR through 2033, driven by tires, batteries, and turbochargers as top segments. Key trends include AI for predictive maintenance, rising EV/hybrid parts demand, and sustainability focus with eco-friendly products. Events like the International Auto Aftermarket EXPO (IAAE) highlight these shifts, growing in scale with international exhibitors.
We provide the TecDoc Catalogue, the world’s leading spare parts database, for accurate vehicle-to-part matching and global sales. Our products support streamlining of workshops and distributors in Japan, reducing manual work, improving inventory, and giving access to up-to-date data via cloud solutions.
