When you spot a sleek sports car or a boxy van from Japan cruising down a street designed for right-hand traffic, you'll immediately notice the driver sitting on the opposite side. Japan is a right-hand drive (RHD) country, meaning steering wheels are mounted on the right side of the cabin. But why did Japan choose this configuration, and how does driving an RHD vehicle impact everyday ownership, safety, and imports?
Understanding the mechanics and regulations behind Japanese car steering wheel sides helps prospective buyers, automotive enthusiasts, and travelers navigate the rules of the road. Let's break down everything you need to know about why these vehicles are built this way and what it means if you own one.
Why Japanese Cars Have Right-Hand Drive
Japan's tradition of driving on the left side of the road—and placing the steering wheel on the right—dates back to the samurai era. Before automobiles existed, samurai walked on the left side of paths so their swords wouldn't accidentally clash with passersby. When railway systems were developed in the 19th century with British assistance, Japan adopted left-side running. This practice naturally transitioned to motor vehicles when cars arrived in the early 20th century.
Unlike the United States and most of mainland Europe, where vehicles are built for left-hand drive (LHD) with drivers sitting near the center of the road, Japanese domestic market (JDM) cars place the driver closer to the curb. This setup helps drivers gauge their distance from pedestrians and narrow road shoulders, which is especially practical given Japan's dense urban environments and narrow rural lanes.
RHD vs. LHD: Mechanical and Ergonomic Differences
Moving the steering wheel to the right side involves more than just shifting the steering column. Japanese manufacturers engineer comprehensive mirror-image layouts for their domestic models.
Cabin Layout and Controls
- Turn Signals and Wipers: On most JDM cars, the turn signal stalk is on the right side of the steering column, while the wiper stalk is on the left. This is the exact opposite of standard LHD layout in North America, leading to many initial instances of turning on your windshield wipers when you meant to signal a turn.
- Pedal Placement: The accelerator, brake, and clutch pedals remain in the same physical left-to-right order (left foot clutch, right foot brake and gas), but their spatial alignment relative to the driver's body shifts slightly to match the offset seating position.
- Center Console and Dashboard: Climate controls, infotainment screens, and glove boxes are often angled or redesigned slightly toward the driver, even in an RHD configuration, to maintain ergonomic access.
Mechanical Adjustments
- Steering Rack and Linkage: The steering rack, universal joints, and power steering pumps are engineered specifically for right-side placement. Importing an RHD car into an LHD country often makes steering component replacements tricky, as domestic parts stores may only stock LHD equivalents.
- Headlight Alignment: JDM headlights are designed to dip their beams to the left to illuminate the sidewalk and avoid blinding oncoming traffic. If you drive an RHD car in a right-hand traffic country (like the US or Canada), your headlights will glare directly into the eyes of oncoming drivers unless you swap or readjust the projector cutoffs.
Driving an RHD Car in Left-Hand Traffic Countries
Importing a JDM vehicle into a country that drives on the right side of the road comes with unique operational challenges. While it's legal in many jurisdictions—provided the vehicle meets local age and safety import rules, such as the 25-year rule managed by the National Highway Traffic Safety Administration—drivers must adapt to several blind spots.
Making a left-hand turn across oncoming traffic is relatively straightforward, but making a safe right-hand turn across multiple lanes requires caution. Because you sit on the right side of the car, your visibility around large vehicles stopped ahead of you (like delivery trucks or buses) is severely restricted. Many RHD owners install wide-angle rearview mirrors or front-facing corner cameras to mitigate this visibility deficit.
Drive-thru windows, toll booths, and parking garage ticket dispensers also present everyday hurdles. Unless you have a passenger to assist, you'll find yourself unbuckling your seatbelt, opening the door, or reaching awkwardly across the center console just to grab a parking ticket or pay for coffee.
Common Mistakes When Buying or Importing JDM Cars
Enthusiasts often rush into purchasing a Japanese import without checking critical details regarding the steering system and vehicle history. Avoid these frequent missteps:
- Ignoring Steering Rack Wear: Many Japanese imports spend years in heavy city traffic or regions prone to road salt. Check the steering boots and power steering fluid for leaks before purchasing.
- Overlooking Turn Signal Confusion: Failing to practice driving in a quiet parking lot before hitting public roads can lead to dangerous mix-ups between wipers and blinkers during emergency maneuvers.
- Assuming Direct Parts Compatibility: Don't assume suspension bushings, tie rods, and steering arms from a local LHD version of the same car will bolt right onto a JDM spec chassis. Always verify part numbers.
Frequently Asked Questions
Can you legally convert a right-hand drive car to left-hand drive?
While it is technically possible, converting an RHD car to LHD is prohibitively expensive and structurally complex. It requires cutting the firewall, sourcing an LHD dashboard, rerouting wiring harnesses, and modifying the steering rack and pedal box. For most vehicles, the cost outweighs the benefit.
Do all Japanese cars have the steering wheel on the right?
Not exclusively. Japanese manufacturers build LHD versions specifically for export markets like the US, Europe, and the Middle East. Furthermore, wealthy car enthusiasts in Japan sometimes purchase luxury European LHD cars as a status symbol, though they account for a small percentage of total vehicles on the road.
Are RHD cars harder to insure?
Insurance rates vary by region and provider. Some specialty insurers view JDM imports as higher risk due to parts scarcity and unfamiliarity with right-hand positioning, while others treat them like standard classic or imported vehicles. Always get an insurance quote before finalizing an import purchase.
How do you pass drive-thru lanes safely in an RHD car?
Most RHD owners either back through drive-thrus, use passenger assistance, or simply park and walk inside. While unconventional, adapting to these small inconveniences quickly becomes second nature for dedicated JDM enthusiasts.
