Radio Act and Imported Radio Equipment

The Radio Act and imported radio equipment refers to the Japanese regulatory checks that may apply to imported products that emit radio waves in Japan.

Examples include Bluetooth devices, Wi-Fi devices, wireless modules, IoT devices, wireless cameras, drones, smart appliances, smart locks, wearable devices and other imported products with radio communication functions.

Even if a product is legally sold overseas, it may still require confirmation under Japan’s Radio Act before it can be used or sold in Japan as radio equipment.

Overview

The Radio Act is a Japanese law intended 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 technical standards conformity may become relevant. For many consumer devices such as mobile phones, Wi-Fi devices and Bluetooth devices, users can often use the equipment more easily if the equipment has received the required certification and displays the appropriate conformity mark.

The representative mark is commonly known as the Giteki mark.

For import practice, the key issue is not only whether the goods can clear customs. Importers and sellers should also confirm whether the product can emit radio waves legally in Japan after import.

Imported Equipment Commonly Affected

Imported equipment that may require confirmation under the Radio Act includes:

• Bluetooth earphones and Bluetooth speakers
• Wi-Fi routers and wireless LAN equipment
• Smartphones, tablets and SIM-free devices
• Wireless cameras and baby monitors
• Smartwatches and wearable devices
• IoT sensors and devices with built-in wireless modules
• Drones, radio-controlled devices and remote-control equipment
• Smart appliances, smart locks and smart lighting
• Transceivers and radio equipment designed for overseas markets

Even if the product looks like ordinary household goods or electrical equipment, confirmation may be necessary if it contains Bluetooth, Wi-Fi, LTE, Zigbee, LoRa, LPWA or another wireless communication function.

Drones require particular attention because the Radio Act may overlap with Aviation Act requirements such as aircraft registration, flight permission or approval, and aircraft certification. These points should be checked separately depending on the product and intended use.

What Is the Giteki Mark?

The Giteki mark indicates that radio equipment conforms to Japan’s technical standards under the Radio Act.

The mark or certification information may appear on the product body, label, screen display, instruction manual or manufacturer documents. For smartphones and tablets, the Giteki mark and certification number may be shown in the device settings screen.

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

Technical Standards Conformity Certification and Construction Design Certification

Two important systems related to Giteki are Technical Standards Conformity Certification and Construction Design Certification.

Technical Standards Conformity Certification generally confirms whether individual radio equipment conforms to Japan’s technical standards.

Construction Design Certification is generally used for radio equipment manufactured under the same design or model, where the design and production control system are checked for conformity with technical standards.

In import practice, importers should not simply ask whether the product “has Giteki.” They should confirm the model, wireless method, frequency band, certification number, display method and whether the imported product actually matches the Japanese-certified version.

Special System for Experiments Using Equipment Without Giteki

Some foreign radio equipment without Giteki may be used in Japan under a special system for experiments, tests or research, if the required notification is filed with the Ministry of Internal Affairs and Communications and the applicable conditions are satisfied.

This system is intended for limited experimental, testing or research use. It is not a general substitute for Giteki certification and should not be treated as permission for ordinary commercial sale.

Whether the system can be used depends on the purpose, period, equipment type, technical conditions and notification details.

Customs Clearance and Domestic Use or Sale Are Different Questions

Customs clearance and lawful domestic use or sale are different questions.

A wireless product may be imported as cargo, but if it will emit radio waves in Japan, the Radio Act may still require confirmation before use, sale or demonstration.

If a problem is discovered after domestic sale, the seller may face returns, consumer complaints, retailer claims, administrative attention, sales suspension or reputational damage.

For this reason, checking before import or sale is safer than trying to handle the issue after distribution has already begun.

Difference from the Telecommunications Business Act

The Radio Act and the Telecommunications Business Act are both important for imported communication devices, but they focus on different points.

Item	Radio Act	Telecommunications Business Act
Main target	Radio equipment that emits radio waves	Terminal equipment connected to telecommunications carrier networks
Typical examples	Wi-Fi devices, Bluetooth devices, wireless modules, drones, radio equipment	Smartphones, modems, LTE routers, IP phones, fax machines, communication modules
Main check point	Frequency, output power, interference prevention and Giteki mark	Technical standards conformity, design certification and connection conditions for terminal equipment
Practical question	Does the product emit radio waves in Japan?	Will the product connect to a Japanese telecommunications carrier network?

Smartphones, LTE routers, IoT gateways and similar equipment may require checks under both laws because they emit radio waves and may also connect to telecommunications carrier networks.

Relationship with Other Japanese Regulations

Imported wireless equipment may also require checks under other Japanese regulations.

If the product includes an AC adapter, charger or power cord, PSE Mark requirements under the Electrical Appliances and Materials Safety Act may become relevant.

If the product connects to telecommunications carrier networks, the Telecommunications Business Act may also need to be checked. Consumer products may involve the Consumer Product Safety Act, product accident reporting, household goods labeling rules or advertising-related regulations.

Therefore, Bluetooth devices, Wi-Fi devices, IoT devices and smart appliances should not be checked only from the viewpoint of customs clearance or only from the viewpoint of the Radio Act. The whole product should be reviewed.

Overseas E-Commerce, Samples and Exhibition Goods

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

Overseas-version smartphones, Wi-Fi devices, Bluetooth devices, wireless cameras and IoT devices may not have Japanese Giteki certification.

Even for sample imports or exhibition goods, if the device will actually emit radio waves in Japan during demonstration, testing or exhibition, Radio Act confirmation may be necessary.

Descriptions such as “not for sale,” “for testing” or “for exhibition” do not automatically remove the need for confirmation. The practical question is whether the device will emit radio waves in Japan.

Products with Built-In Wireless Modules

In recent years, wireless modules may be built into machinery, appliances, measuring devices, medical or beauty devices, industrial equipment and other finished products.

Even if the finished product does not look like radio equipment, it may contain Bluetooth, Wi-Fi, LTE, LPWA or another wireless module.

Importers should check product specifications, instruction manuals, model numbers, module certification numbers, wireless method, frequency band, output power and display method.

They should also confirm whether the product or built-in module is designed and certified for use in Japan.

Forwarder and Customs Broker Practical Notes

Forwarders and customs brokers are not normally responsible for guaranteeing Radio Act compliance.

However, if product names, invoices, packing lists, product descriptions, HS codes or product photos include terms such as Bluetooth, Wi-Fi, wireless, radio, RF, smart, IoT, drone, router or module, it is useful to remind the importer to check Radio Act requirements.

HS codes alone do not always reveal the wireless function. Electrical equipment, machinery, drones and embedded-module products may require attention if they include wireless communication functions.

In practice, forwarders should encourage the importer to confirm the following points:

• Is the product designed for the Japanese market?
• Does it have a Giteki mark or certification number?
• Where is the mark or certification number displayed?
• What wireless method and frequency band does the product use?
• Is the product relying only on overseas standards such as FCC or CE?
• Is the product for sale, exhibition, testing or personal use?
• Will the product emit radio waves in Japan?
• Is the special experimental-use system for equipment without Giteki relevant?
• Are Telecommunications Business Act, PSE or other regulatory checks also required?

Documents and Information to Check

• Product specification sheet
• Instruction manual
• Product photos
• Giteki mark or certification number display materials
• Wireless module model information
• Wireless method, frequency band and output power information
• Manufacturer documents showing Japanese-market specifications
• Notification documents where the special experimental-use system is used
• Invoice
• Packing list
• Sales page or product description page
• Other regulatory certification or labeling documents

Common Problems

• The importer assumes that FCC, CE or other foreign certification is enough for Japan.
• The product has wireless functions, but the invoice describes it only as ordinary goods.
• The Giteki mark is not confirmed before sale.
• The certification number does not match the imported model.
• A built-in wireless module is overlooked.
• A sample product is used for live demonstration in Japan without checking Radio Act requirements.
• The importer confuses Radio Act confirmation with Telecommunications Business Act confirmation.
• PSE requirements for AC adapters, chargers or power cords are overlooked.

These problems may lead to sales suspension, return handling, customer complaints, administrative attention, relabeling work, marketplace suspension or additional confirmation after import.

Practical Notes for Shipments to Japan

For Japan-bound wireless products, origin-side suppliers and forwarders should understand that customs clearance is only one part of the process.

The practical question is not only whether the goods can enter Japan, but whether the product can emit radio waves and be used, demonstrated or sold in Japan under the applicable rules.

Early confirmation helps avoid sales delay, exhibition problems, return handling, platform listing issues and unexpected additional checks after arrival.

Key Takeaway

The Radio Act is important for imported products that emit radio waves in Japan.

Overseas certification does not automatically mean that the product can be used or sold in Japan. Giteki mark, certification number, wireless method, frequency band, Japanese-market specifications and other related regulations should be checked before shipment or sale.

Forwarders and customs brokers do not guarantee Radio Act compliance, but they can help prevent problems by reminding importers to confirm Giteki, certification number, Japanese-market specifications, experimental-use exceptions and related laws such as the Telecommunications Business Act and PSE requirements.
