Stay Roadworthy for Japan’s Vehicle Inspections

Japan is known for its efficient roads, safe driving environment, and exceptionally high vehicle standards. Part of maintaining that system involves strict vehicle inspections, better known as Shaken (車検). If you own a car in Japan—or plan to—understanding how to keep your vehicle roadworthy is essential not just for legal compliance, but also for safety and long-term cost savings.

At Direct Cars Japan, we’ve helped countless customers buy, maintain, and prepare vehicles for inspection. Here’s a detailed guide on how to stay ahead of the curve when it comes to Japan’s shaken system.

🚗 What Is the Shaken Inspection?

Shaken, or the Japanese Compulsory Vehicle Inspection, is a thorough check of your vehicle required every two years (after the first three years of new car ownership). It's designed to ensure cars on Japanese roads meet safety and emissions standards.

Failing the inspection means your vehicle cannot be legally driven until it passes—and the process isn’t cheap. That’s why keeping your car roadworthy year-round is the smart way to go.

 

🧰 1. Routine Maintenance Is Your First Line of Defense

Routine checks go a long way in ensuring your car is always inspection-ready. Here are the basics to stay on top of:

Oil and Fluid Changes: Regularly change engine oil, brake fluid, coolant, and transmission fluids.

Brake Pads and Rotors: Worn-out brakes are a common failure point. Replace them well before they get dangerously thin.

Lights and Signals: Make sure all headlights, tail lights, brake lights, and turn indicators work perfectly.

Wipers and Washer Fluid: Inspect for tears and keep the fluid topped up—yes, even this is checked!

At Direct Cars, all our vehicles go through thorough pre-sale maintenance including oil changes and full service, so you're already a step ahead.

 

🛞 2. Tire Condition & Alignment Matter More Than You Think

Many car owners overlook tires, but tire tread depth, sidewall condition, and proper air pressure are all key parts of the inspection.

Ensure you have at least 1.6mm of tread depth.

Look for cracks, bulges, or uneven wear.

Get your wheels balanced and aligned annually.

When you buy from Direct Cars Japan, we ensure all vehicles come with good-condition tires that are shaken-ready.

 

🔋 3. Battery and Electrical Systems

Dead or weak batteries are a leading cause of inspection delays. Make sure your battery holds charge well, especially during winter months. Faulty wiring or exposed cables can also be flagged.

If your vehicle has electronics such as a navigation system, backup camera, or ETC reader, ensure they're installed properly and don’t interfere with safety systems.

 

🔧 4. Undercarriage & Exhaust Check

This part is where things get strict. Your car’s underbody is checked for:

Rust and corrosion

Leaks from the exhaust, engine, or transmission

Excessive wear or damage to the suspension

Exhaust systems must also meet Japanese emission standards, especially for older cars. If your vehicle has been modified, check that it adheres to legal specifications.

At Direct Cars, we inspect undercarriages thoroughly before listing a car, so buyers can drive with confidence.

 

🔍 5. Dashboard Warnings & Inspection Stickers

If any warning lights (like check engine or ABS) are illuminated during inspection, it’s an automatic fail. Get diagnostic scans done if needed and repair underlying issues early.

Also, make sure your inspection and tax stickers are visible and up to date.

 

🛠️ Pro Tip: Schedule a Pre-Shaken Check

A few months before your inspection is due, take your vehicle to a certified mechanic for a pre-shaken inspection. It’s better to spend a little now than be surprised with a huge repair bill later.

Many shops offer shaken preparation packages that include:

Emissions testing

Alignment checks

Brake system flush

All fluid top-ups
