Introduction: What Are Japan License Plates and Why They Matter
Japan license plates are the official vehicle identification plates issued by Japanese authorities for every registered car, truck, or motorcycle operating on public roads. They contain a combination of:
Prefecture identifiers (often in Japanese characters),
Hiragana scripts,
Numerical registration codes, and
Color schemes that indicate vehicle type.
When Japan license plates for sale appear online, they might be one of these:
Genuine decommissioned plates originally used on Japanese vehicles,
Replica plates designed to mimic authentic plates,
Decorative or novelty plates meant for aesthetic use only, and
Custom plates that copy the style but are tailored for markets outside Japan.
Authentic Japanese license plates have cultural and historical value. They reflect Japan’s strict vehicle registration system, and true originals are often collectible. For automotive fans, adding genuine plates to a display car, garage wall, or collection can be deeply meaningful.
However, finding legitimate plates requires understanding how to identify them correctly. That’s where this guide helps you.
Section 1: Understanding Official Japan License Plates
What Official Plates Look Like
Genuine Japanese license plates follow specific standards established by Japan’s Ministry of Land, Infrastructure, Transport and Tourism. Here is what to know:
1. Plate Dimensions and Material
Authentic Japan license plates are standardized in size, usually measuring approximately 6.5 inches (165 mm) high x 13 inches (330 mm) wide and made from metal with embossed characters.
2. Color Coding
Japanese plates use distinct colors to signify vehicle types:
White plates with green text for ordinary passenger vehicles.
Yellow plates with black text for kei vehicles (small engine under 660 cc).
Green plates with white text for commercial vehicles.
3. Character Layout
Real plates contain:
A prefecture name or code in Kanji or Japanese script,
A regional class number, and
Hiragana characters followed by a serial number.
These elements are unique to Japan’s registration system and are not decorative.
Why Official Plates Are Hard to Find Abroad
In Japan, license plates are typically turned in to authorities when a vehicle is deregistered or exported. This means legitimately used plates with their full registration history are rare outside of Japan. Because of this, many Japan license plates for sale are replicas or decorative versions designed for enthusiasts.
Used real plates that survive outside Japan often have distinguishing marks such as a punched hole from removal, and signs of weathering. Plates without these signs are often manufactured replicas.
Section 2: Common Types of Japan License Plates for Sale
When you are shopping for Japan license plates for sale, understanding the different types you might encounter helps you know what you are buying.
1. Official Authentic Japanese Plates
These are plates that were previously used on vehicles in Japan. They often show:
Wear and patina from road use,
A stamped or embossed identification, and
In many cases, a hole drilled or stamp mark where the seal was removed.
These plates might come from export vehicles brought overseas by owners, or plates released from retired vehicles. True originals are often sold by specialty collectors.
2. Licensed Replicas
Many legitimate sellers produce high quality licensed replicas that copy official plate standards in color, material, and design. These are perfect for display, car shows, or personal collections. For example, the Japanese License Plate - Customizable & Authentic JDM Style from Oiwa Garage is made from weather‑resistant aluminum, keeps embossed characters, and matches the size and look of traditional plates.
3. Custom Decorative Plates
These are crafted with Japanese style characters but may not follow official registration rules. They might include personalized text, humorous designs, or stylistic elements that are not part of any Japanese plate standard.
Be careful, because although these plates are beautiful and perfect for decoration, they are not official and should not be used for vehicle registration. Many decorative plates do not use proper fonts, proper character sequence, or Japanese prefecture designations.
Section 3: Identifying Genuine Japan License Plates
Now that you know the types of plates available, let us dig into how to identify genuine Japan license plates when you are shopping.
Look at Physical Features
Authentic Asian plates have specific physical signs:
Embossed Characters. Authentic Japanese plates have raised, embossed letters and numbers. Flat printed or low‑quality text suggests a replica.
Correct Size and Hole Spacing. Japanese license plates follow standardized dimensions and hole spacing. If the plate is too small or too large, it may be a decorative copy.
Font and Script Accuracy. Genuine plates use specific character styles for Hiragana and Kanji. Incorrect font styles indicate non‑official products.
Examine Genuine Registration Clues
Real plates have registration‑specific indicators:
Prefecture names or codes in Kanji,
Hiragana characters following the regional code, and
Consistent number formats that match the official Japanese plate system.
If a plate has random characters, Western letters integrated incorrectly, or character placements that differ from Japan’s standards, it is likely a replica or novelty plate.
Check for Wear and History
Authentic used plates often show signs that suggest real usage:
Weathering, scratches, fading, or oxidation,
Internal stamps at the back indicating production marks,
Hole for the official seal that was affixed when the plate was registered.
A plate that looks too perfect, shiny, or brand new is likely not an official retired plate but a replica designed to mimic the style.
Section 4: Where to Safely Find Japan License Plates for Sale
Once you know what to look for, you need trustworthy sources where you can browse Japan license plates for sale that meet your needs.
Specialist Online Retailers
Sellers like Oiwa Garage specialize in Japanese automotive culture and offer high‑quality JDM accessories. For example, Oiwa Garage offers:

Such retailers often provide detailed product descriptions and clear images so you can inspect materials and authenticity features before buying.
Collector Marketplaces
Platforms like eBay, dedicated license plate forums, and collector groups often list genuine retired plates from vehicles once registered in Japan. When buying from individuals, ask for clear photos of both sides, close‑ups of characters, and any provenance information.
Avoid Low‑Quality Novelty Plates When Needed
Be cautious with marketplace listings that use generic descriptions like “Japanese style plate” without details like dimensions, material, embossing, or authentic characters. These are often novelty or vanity products that may not resemble real Japanese plates accurately.
Section 5: Tips to Avoid Buying Fake or Misleading Plates
You now know what plates should look like and where to find them, but here are professional tips to protect yourself when browsing Japan license plates for sale:
Ask for Clear Details and Specifications
Always confirm:
Material type (aluminum vs plastic),
Embossed or printed characters,
Exact dimensions,
Whether it is an official used plate or a replica,
Shipping and return policies.
Research the Seller and Product Reviews
Check if the seller has authentic testimonials, product photos, and company background. Genuine sellers like those focused on JDM parts often provide more accurate product information.
Compare with Real World Examples
Search online for photos of official Japanese plates and compare the characters, colors, and fonts with what is listed in the product photos.
Know Local Vehicle Laws
Be aware that even authentic plates are not legal for use on public roads in most countries unless they have been officially registered under local laws. They are typically for show, decoration, or collection only.
