Radio Act and Imported Wireless Equipment in Japan

Overview

The Radio Act and imported wireless equipment refer to the regulatory checks required when importing products that emit radio waves for use or sale in Japan.

Products such as Bluetooth devices, Wi-Fi equipment, wireless modules, IoT devices, wireless cameras, drones, smart appliances and smart locks may require confirmation under Japan’s Radio Act before they can be used or sold domestically.

Even if a product is lawfully sold overseas, it may not automatically be lawful to use in Japan as radio equipment. The importer or seller must confirm whether the equipment conforms to Japanese technical standards and whether the required certification or marking is available.

This issue often arises in overseas e-commerce, crowdfunding, direct import from overseas manufacturers, sample import, exhibition cargo, used or repaired equipment, and products that contain wireless modules inside machinery or electrical devices.

What the Radio Act Means

The Radio Act is a Japanese law designed to ensure fair and efficient use of radio waves and to prevent harmful interference with wireless communication.

When radio equipment is used in Japan, radio station licensing or conformity with technical standards may become an issue. For many consumer devices such as smartphones, Wi-Fi devices and Bluetooth devices, the user-side procedure is simplified when the equipment has obtained the required technical conformity certification or construction design certification.

The mark commonly known as the Giteki Mark indicates that the relevant radio equipment conforms to Japanese technical standards under the applicable certification system.

Imported Equipment That Often Requires Confirmation

Imported products that may require Radio Act confirmation include:

• Bluetooth earphones and Bluetooth speakers;
• Wi-Fi routers and wireless LAN devices;
• smartphones, tablets and SIM-free devices;
• wireless cameras and baby monitors;
• smart watches and wearable devices;
• IoT sensors and devices containing wireless modules;
• drones, radio-controlled devices and remote-control equipment;
• smart appliances, smart locks and smart lighting products;
• transceivers and radio equipment intended for overseas markets.

Even if the product appears to be ordinary general merchandise or electrical equipment, Radio Act confirmation may be required if it uses Bluetooth, Wi-Fi, LTE, Zigbee, LoRa, RF communication or other wireless functions.

Drones require particular care. In addition to Radio Act confirmation for wireless communication, aviation-related rules such as aircraft registration, flight permission or approval, and aircraft certification may also become relevant depending on the use and product type.

Giteki Mark

The Giteki Mark is a conformity mark showing that radio equipment complies with Japanese technical standards under the Radio Act.

The Giteki Mark or certification number may appear on the product body, label, screen display, package, user manual or device settings screen. For smartphones and tablets, the mark or certification information may be shown inside the device settings menu.

Where the Radio Act certification system applies, proper display of the Giteki Mark or certification information is an important requirement for domestic use or sale in Japan. Therefore, importers should confirm not only that certification exists, but also how and where the mark or certification number is displayed.

Products manufactured for overseas markets may show FCC, CE, UKCA or other foreign conformity marks but may not have Japan’s Giteki Mark. Compliance with foreign standards does not automatically mean that the product can be used or sold in Japan under the Radio Act.

For importers and sellers, it is important to confirm not only whether the product has a mark, but also whether the model number, wireless module, frequency band and Japanese-market specification match the product actually being imported.

Technical Conformity Certification and Construction Design Certification

Two important certification concepts are technical conformity certification and construction design certification.

Technical conformity certification is generally used to confirm whether specific radio equipment complies with the technical standards under the Radio Act.

Construction design certification is generally used for mass-produced radio equipment of the same design or model, where the design and manufacturing control are certified as conforming to the technical standards.

In import practice, it is not enough to ask simply whether the product has “Giteki.” The parties should confirm the product model, radio method, frequency band, certification number, display method and whether the imported version is the same as the Japan-certified version.

Customs Clearance and Lawful Use or Sale Are Different

One of the most important points in import practice is that customs clearance and lawful use or sale in Japan are separate issues.

A product may pass customs procedures as cargo, but if it emits radio waves in Japan, Radio Act compliance may still be required before domestic use or sale.

If a problem is found after domestic sale, the seller may face customer returns, business claims, product withdrawal, administrative guidance or reputational risk. Confirmation before import and sale is usually safer than dealing with problems after distribution.

Forwarders and customs brokers generally support the importer’s customs procedures and logistics arrangements. They are not usually responsible for guaranteeing Radio Act compliance. However, when the cargo appears to include wireless functions, it is important in practice to remind the importer to confirm the Giteki Mark, certification number and domestic use conditions.

Relationship with Other Laws and Regulations

Imported wireless equipment may involve laws and regulations other than the Radio Act.

For example, if the product includes an AC adapter, charger or power supply, the Electrical Appliance and Material Safety Act and PSE Mark may become relevant. If the product is connected to a public telecommunications network, the Telecommunications Business Act may also need to be checked.

Consumer product safety rules, household goods labeling rules and advertising rules may also become relevant depending on the product and sales method.

For this reason, importers should not assume that checking the Radio Act alone is enough. The entire product should be reviewed from the viewpoint of wireless communication, electrical safety, telecommunications connection, product safety, labeling and consumer sales.

Overseas E-commerce, Crowdfunding and Sample Imports

Products purchased through overseas e-commerce platforms or crowdfunding campaigns may not be designed for the Japanese market.

Overseas versions of smartphones, Wi-Fi devices, Bluetooth products, wireless cameras and IoT equipment may not have Japanese technical conformity certification, even if they are sold normally in another country.

Sample imports and exhibition cargo also require caution. Even if the product is not sold, Radio Act issues may arise if it is actually powered on and emits radio waves during testing, demonstration or exhibition in Japan.

Used equipment, repaired equipment, refurbished products and modified products also require attention. Even if the original model once had certification, repair, modification, replacement of wireless modules, antenna changes or different market specifications may affect whether the certification number and Giteki display still match the actual product.

The practical dividing point is often whether the product emits radio waves in Japan. A product described as “not for sale,” “sample,” “test use,” “used product,” “repair return” or “exhibition use” may still require confirmation if it will be operated domestically.

Exception System for Experimental Use of Non-Certified Equipment

Japan has a special system that may allow certain non-certified radio equipment to be used for experiment, testing or research purposes for a limited period under specified conditions after notification.

This system is not a general substitute for ordinary certification and should not be treated as a basis for normal commercial sale.

Whether the system can be used depends on the purpose, period, equipment type, technical conditions and notification details. Importers should confirm the requirements before bringing the product into Japan or using it domestically.

Products Containing Wireless Modules

In recent years, wireless functions are often built into products that do not look like radio equipment from the outside.

Machinery, home appliances, measuring equipment, medical or beauty devices and industrial equipment may contain Bluetooth, Wi-Fi, LTE, LPWA or other wireless modules.

In these cases, the importer should check the product specifications, user manual, model number, module certification number, communication method, frequency band, output power and display method.

A certified wireless module does not always solve every issue automatically. The final product configuration, antenna, installation method, labeling and Japan-market specification may still need confirmation.

Practical Points for Forwarders and Customs Brokers

Forwarders and customs-related parties are not usually in a position to guarantee whether radio equipment is lawful for use or sale in Japan.

However, if the cargo name, invoice, packing list, product description, HS code or product photos include words such as Bluetooth, Wi-Fi, wireless, radio, RF, smart, IoT, drone, router or module, the forwarder should recognize that Radio Act confirmation may be needed.

Wireless functions may appear in goods classified under electrical machinery, general machinery, aircraft or drone-related classifications, consumer goods or industrial equipment. The HS code alone does not determine whether Radio Act confirmation is necessary.

In practice, it is useful to ask the importer the following questions:

• whether the product is a Japan-market model;
• whether the Giteki Mark or certification number is available;
• where the mark or certification number is displayed;
• what wireless communication method and frequency band are used;
• whether the product has only foreign marks such as FCC, CE or UKCA;
• whether the product is new, used, repaired, refurbished or modified;
• whether any wireless module, antenna or communication-related part has been replaced;
• whether the product is for sale, exhibition, testing, sample use or personal use;
• whether the product will emit radio waves in Japan;
• whether a non-certified equipment exception system is being considered.

Documents and Information to Check

The following documents and information may be useful when checking imported wireless equipment:

• product specifications;
• user manual;
• product photographs;
• Giteki Mark or certification number evidence;
• wireless module model information;
• communication method, frequency band and output power information;
• manufacturer documents showing Japan-market specification;
• repair, refurbishment or modification history where relevant;
• notification documents if using an exception system for non-certified equipment;
• invoice;
• packing list;
• sales page or product description page;
• documents related to other laws such as PSE or telecommunications terminal rules.

For importers, the most important point is to confirm the actual product version. A model name used overseas may look similar to the Japan-market model but may have different wireless specifications or certification status.

Practical Notes for Shipments to Japan

For shipments to Japan, overseas shippers and origin-side forwarders should not assume that a product is acceptable merely because it is sold legally in another country.

Japanese importers may ask for evidence of Giteki Mark, certification number, wireless module information, frequency band, Japanese-market specification or documents for experimental-use exceptions.

Overseas suppliers should respond with technical documents rather than only a commercial product name. If the product contains a wireless module, the module information and final product configuration should also be confirmed.

Where the product is imported for exhibition, testing or research, the parties should check whether it will actually emit radio waves in Japan and whether any special notification or limitation applies.

For used, repaired, refurbished or modified wireless equipment, the parties should confirm whether the certification information still corresponds to the actual product condition. A product that looks identical from the outside may differ in module, antenna, firmware, frequency setting or market specification.

Key Takeaway

The Radio Act is important for imported products that emit radio waves, including Bluetooth, Wi-Fi, IoT, wireless camera, drone and wireless module products.

Foreign conformity marks such as FCC, CE or UKCA do not automatically mean that the product can be used or sold in Japan. Japan’s Giteki Mark, certification number, required display and technical conformity status should be checked where relevant.

Customs clearance and lawful domestic use or sale are separate issues. Forwarders and customs-related parties should encourage importers to confirm Radio Act compliance, Giteki Mark, certification number, Japan-market specification, used or modified product status, possible exception systems and related laws before import or domestic distribution.
