Definition
自動車 (jidousha) means an automobile: a motorized road vehicle designed to carry passengers or cargo under its own power.

Meanings
- As a legal/administrative category used in registration, licensing and vehicle taxation distinct from bicycles or trailers.
- In technical contexts, a term covering multiple classes of motor vehicles (passenger cars, commercial trucks, buses) rather than only private cars.
- Used metonymically to refer to the automotive sector, e.g., industry, markets, or manufacturing when paired with other words.
- In compounds and set phrases to specify vehicle-related systems or services such as insurance, maintenance, and traffic rules.
Origin
The concept arrived with Western motor vehicles imported into Japan during the late 19th and early 20th centuries; domestic manufacturing grew in the Taisho–Showa periods with early Japanese models appearing in the 1930s and expanding postwar into a major industry, after which regulatory frameworks and common usage standardized the word for motor vehicles.
Composition
- 自 (ji): self, automatic.
- 動 (dou): move, motion.
- 車 (sha): vehicle, cart.
- Together they convey the idea of a vehicle that moves by its own power—i.e., a motor vehicle.
Usage
Common in formal, legal, and technical contexts—official documents, registration papers, traffic reports, insurance and manufacturer materials—while everyday conversation often shortens it to the casual 車 (kuruma). It appears in news coverage about traffic, policy, or industry and in compound terms referring to vehicle types, taxes, and services.
💡 Tips
Think “self + move + vehicle”: picture a vehicle that moves by itself to remember 自動車 (jidousha); linking the three kanji meanings makes the compound intuitive.
Variations
