However, when searching for "Sun Emperor" or "Sun Emperor" online, negative keywords such as "illegal," "police," and "license" sometimes appear in suggested searches. This seems to cause many potential buyers to feel uneasy, wondering if "this vehicle is really safe to ride on Japanese public roads?" or "is there a risk of being caught by the police?"

To put it simply, the applicable models offered by Sun Emperor are fully compliant with Japan's Road Traffic Act as legal "specific small mopeds," and there is absolutely no illegality involved.

This article provides a comprehensive explanation, spanning over 3000 characters and incorporating specialized legal terminology, of the safety and legal standing of Sun Emperor, a brand developed by the Japanese manufacturer Ryusho Co., Ltd. It also clarifies why it can be ridden without a license by individuals aged 16 and over, and details the strict rules for riding on public roads and sidewalks. By reading this article, all your questions and concerns will be resolved, enabling you to confidently embark on a new electric mobility lifestyle.


1. Why is "Sun Emperor Illegal" a Search Term? Unraveling the Misconceptions

Why is a quality mobility device like Sun Emperor viewed with suspicion, leading to searches like "illegal"? This stems from news reports of illegal riding involving "pedal-assisted electric bicycles" (commonly known as "mopeds") that are prevalent in Japan, and a lack of awareness regarding the revised Road Traffic Act that came into effect on July 1, 2023.

The Crucial Difference from Illegal "Full Electric Bicycles (Mopeds)"

Currently, a major social problem on Japanese roads involves inexpensive imported full-electric bicycles, often from China, that look like ordinary bicycles (with pedals) but can self-propel solely with motor power. Under Japanese law, these are generally classified as "general mopeds (Class 1)." Therefore, it is entirely "illegal" to ride them without proper safety equipment like rearview mirrors and turn signals, a moped license, and a helmet, and they must be ridden on the road. Many illegal moped users disregard these rules, riding without licenses or helmets on bicycle lanes and sidewalks. This has led to increased police enforcement and the misconception that "any electric vehicle that moves without pedaling is illegal."

Sun Emperor: A New, Legal Category of "Specific Small Moped"

In contrast, Sun Emperor's main models (such as Easy, SS1, SUNRIN, LBIRD) are developed and manufactured under a completely different legal framework: the "specific small moped." This is a new, official vehicle category recognized by the government, established through the Road Traffic Act revision in July 2023. If the vehicle meets the specified standards, anyone aged 16 or older can legally operate it on public roads without a driver's license.

2. Domestic Manufacturer "Ryusho Co., Ltd." Ensures Overwhelming "Reliability" and "Compliance with Safety Standards"

When importing or parallel importing electric kickboards or electric motorcycles from overseas, there are many cases where they do not meet Japan's strict safety standards. However, Sun Emperor is a brand originating from Japan, with its planning, operation, and sales handled by Ryusho Co., Ltd., a domestic manufacturer headquartered in Nagoya. This is the key factor that provides users with maximum "peace of mind."

Passed the "Safety Standards Conformity Confirmation Test" Recognized by the Government

To operate as a specific small moped on Japanese public roads, vehicles must clear extremely stringent "safety standards" stipulated by the Ministry of Land, Infrastructure, Transport and Tourism. Sun Emperor vehicles have undergone inspection by organizations such as the Japan Automobile Transport Technology Association (JATA) and have officially passed the "Safety Standards Conformity Confirmation (Performance and Standards Confirmation System)." A sticker indicating "Performance and Standards Confirmed" is affixed to the vehicle, serving as proof that it is a "safe vehicle approved by the government." Therefore, even if stopped by a police officer, there is nothing to be ashamed of, and its legality can be confidently asserted.

Comprehensive Domestic After-Sales Support System

Electric mobility devices, such as those made by Sun Emperor, require regular maintenance due to battery degradation, tire wear, and brake adjustments. Unlike overseas businesses that merely sell products and offer no further support, Ryusho Co., Ltd., as a domestic manufacturer, provides prompt customer support in Japanese for any initial defects or malfunctions. The availability of replacement parts in Japan and maintenance services by specialized staff are among the reasons why their thorough after-sales support (aftercare) for long-term safe use is highly valued in Japan.


3. Specific Small Moped and Special Specific Small Moped Mechanisms and Riding Rules

To operate a Sun Emperor safely and legally, users must accurately understand the rules for "specific small mopeds." As long as these laws are adhered to, all illegality is completely eliminated.

Comparison Criteria for Specific Small Mopeds and Special Specific Small Mopeds
Item Specific Small Moped (Normal Mode) Special Specific Small Moped (Sidewalk Mode)
Maximum Speed 20km/h or less 6km/h or less
Permitted Riding Areas Roadway, bicycle paths, exclusive bicycle lanes Sidewalks (where "ordinary bicycle sidewalk passage permitted" signs are present), bicycle paths
Maximum Speed Indicator Light (Green Lamp) Solid (constantly lit) Flashing (blinking rapidly)
Age Restriction 16 years or older (no license required) 16 years or older (no license required)
Helmet Effort to wear recommended Effort to wear recommended

① No License Required (for ages 16 and up) and Helmet Wearing as an "Effort Obligation"

The greatest advantage of specific small mopeds is that they can be operated without a car or moped license. This makes them a new mode of transportation for seniors who have voluntarily surrendered their licenses and high school students (16 and older) who wish to use them for commuting. Furthermore, while helmet wearing is currently an "effort obligation" under the law, domestic manufacturers strongly recommend wearing a helmet for safety in the event of an accident.

② Road/Sidewalk Switching System via "Maximum Speed Indicator Light"

Sun Emperor vehicles (such as the flagship Easy model and the latest 4-wheel LBIRD) are equipped with a green LED lamp called a "maximum speed indicator light" located at the end of the handlebars or in a highly visible position on the vehicle. The state of this lamp plays a crucial role in indicating to police and pedestrians "which mode the vehicle is currently operating in."

  • Roadway riding mode (max speed 20km/h): The green lamp is "constantly lit." In this mode, the vehicle should be ridden on the far left side of the roadway or on designated bicycle lanes.
  • Sidewalk riding mode (max speed 6km/h): When switching to this mode, the maximum speed is automatically limited to 6km/h (about walking pace), and the green lamp changes to "flashing." A vehicle in this state is legally referred to as a "Special Specific Small Moped," and only in this mode is it exceptionally permitted to ride on sidewalks where "ordinary bicycle sidewalk passage permitted" signs are present.

※Crucial Warning: Switching modes while riding is prohibited by law. When transitioning from the roadway to the sidewalk to change modes, you must always operate the switch only after the vehicle has come to a complete stop. Changing modes while in motion is a violation of the Road Traffic Act (subject to enforcement).


4. To Avoid Being Stopped by the Police! Three Essential Procedures Before Riding on Public Roads

Even if a Sun Emperor vehicle itself is legal and conforms to safety standards, if you ride it on public roads without completing the required administrative procedures mandated by Japanese law, it will be considered "illegal riding" and you will be apprehended by the police. Please ensure you complete the following three steps after purchase.

Step 1: Obtain a License Plate (Light Vehicle Tax Declaration)

Specific small mopeds are required to be registered with municipal offices. By bringing the "sales certificate" included with the vehicle, your identification, and a seal (hanko) to the tax department window of the municipality where you reside, you can receive a specific small moped-exclusive "small license plate (vertical type)" free of charge. Please attach this correctly to the rear of the vehicle.

Step 2: Join Compulsory Automobile Liability Insurance

By law, joining compulsory automobile liability insurance is mandatory. Riding without this insurance is a serious offense (punishable by up to one year imprisonment or a fine of up to 500,000 yen, and license suspension). Enrollment is very easy: after obtaining a license plate at the local government office, you can complete the procedure in minutes, 24 hours a day, at the multi-copy machines in nearby convenience stores (such as 7-Eleven, FamilyMart, and Lawson). Please attach the issued "insurance sticker" to your license plate.

Step 3: Confirmation of Model Recognition and Re-confirmation of Rules

As previously mentioned, Sun Emperor has received type approval from Ryusho Co., Ltd., ensuring a smooth registration process at the local government office. Once the procedures are complete, you can confidently and legally ride on public roads in Japan without any reservations.


5. Enhancing Safety Even Further! Sun Emperor's Unique Design Philosophy

Many electric kickboards (stand-up type) have small tires and inherently suffer from structural disadvantages, making them prone to losing balance on cracked asphalt, manholes, and bumps (such as the border between sidewalks and roadways) commonly found on Japanese roads. This contributes to accidents and the public perception of them as "dangerous."

However, Sun Emperor (especially the familiar "Easy" and the latest 4-wheel model "LBIRD") is designed primarily as a "seated type" (riding style with a saddle). With a low center of gravity and suspension that effectively absorbs road impacts, the risk of tipping over is extremely low compared to stand-up models. Furthermore, the adoption of disc brakes for reliable stopping power and highly visible front and rear turn signals demonstrate a thorough commitment to "quality that Japanese people can safely use as a daily means of transport." This high safety standard is the solid foundation that keeps illegality at bay.


6. Summary: Sun Emperor is a "Safe and Secure" Future Mobility Device that Complies with the Law

Online rumors of "illegality" and "danger" are merely misconceptions born from the confusion between some overseas full-electric bicycles (mopeds) that ignore rules and a lack of awareness regarding legal revisions.

Sun Emperor, responsibly developed by the Nagoya-based domestic manufacturer Ryusho Co., Ltd., is a legitimate specific small moped that complies with Japan's strict safety standards. If you are 16 or older, you don't need a license, and you can travel flexibly and legally from roadways (20km/h) to sidewalks (6km/h) as a special specific small moped, depending on the situation.

By choosing Sun Emperor, which comes with full after-sales support, learning the correct rules, and completing the license plate registration and compulsory insurance, your daily commute will become more comfortable, eco-friendly, and enjoyable. Don't be swayed by rumors; experience cutting-edge electric mobility with a trustworthy domestic brand!
