Why Wireless Device Import Is Regulated Separately From PSE
The common assumption: If a device has a CE mark or FCC ID, it meets Japan's requirements. It does not. Japan's Radio Act (電波法) is an independent regulatory framework administered by the Ministry of Internal Affairs and Communications (MIC / 総務省). CE and FCC certifications have no legal effect in Japan.
The consequence of non-compliance: Using a non-certified wireless device in Japan is a criminal offense under the Radio Act. Customs will flag wireless-capable devices during inspection. Devices imported without Giteki (技適) cannot be legally operated, sold, or demonstrated to clients in Japan.
What Is the Radio Act and Who Administers It?
Japan's Radio Act (電波法) governs the use of radio equipment in Japan. Its purpose is to prevent interference with radio communications and ensure spectrum integrity. The competent authority is the Ministry of Internal Affairs and Communications (MIC / 総務省).
Every device that emits radio waves must either:
- Hold a Technical Conformity Mark (技術基準適合証明 / 技適, also called "Giteki"), or
- Operate under an Experimental Station Licence (実験局免許) for trial or R&D use only
There is no grace period and no de minimis threshold by quantity. A single device imported without certification is already in violation if operated.
Which Devices Require 技適 Certification?
The trigger is radio wave emission. The wireless standard, frequency, or power output does not alter the certification requirement.
Coverage by Wireless Standard
| Wireless Standard | 技適 Required? | Notes |
|---|---|---|
| Wi-Fi (802.11 a/b/g/n/ac/ax) | Yes | All bands: 2.4 GHz and 5 GHz |
| Bluetooth (Classic and BLE) | Yes | Including BT 5.x |
| Cellular (3G / LTE / 5G / NB-IoT) | Yes | Including embedded SIM modules |
| NFC | Yes | All NFC-Forum compliant devices |
| Zigbee / Z-Wave / Thread | Yes | Sub-GHz and 2.4 GHz IoT protocols |
| LoRa / LoRaWAN | Yes | Sub-GHz LPWAN |
| RFID (active) | Yes | Active RFID = radio transmitter |
| RFID (passive) | Assess | Passive RFID: verify case-by-case |
| GPS (receive-only) | No | Receive-only, no transmission |
| Satellite uplink (VSAT, Starlink, LEO) | Yes | Additional approvals required |
| Wired-only devices | No | No RF emission |
⚠️ IoT caution: Many industrial sensors, gateways, and edge computing devices contain embedded wireless modules that are not listed prominently in product specifications. Always verify the bill of materials (BOM) for any wireless module, including sub-GHz LPWAN chips, before assuming a device is wired-only.
Two Certification Pathways
Pathway 1: Technical Conformity Mark (技適)
The standard pathway for commercial sale and operation. A device carrying the 技適 mark has been certified by an MIC-designated testing laboratory and is approved for commercial use in Japan.
| Step | Action | Timeframe |
|---|---|---|
| 1 | Identify applicable Radio Act technical standards for the device | 1 week |
| 2 | Engage MIC-designated testing laboratory (TELEC or JATE) | 1 week |
| 3 | Testing against all applicable frequency bands and technical standards | 4-8 weeks |
| 4 | If tests pass: 技適 certificate issued and device registered in MIC database | 1-2 weeks |
| 5 | 技適 mark applied to device before import or sale | Before shipment |
Total timeline: 6-12 weeks in normal circumstances.
📌 The 技適 mark requirement: The mark must appear on the device itself or, for equipment where physical marking is not practical, displayed clearly in the device's software or firmware menu. This is common for smartphones and tablets. A separate paper certification is not a substitute for the mark on the device.
Pathway 2: Experimental Station Licence (実験局免許)
For devices being imported for testing, R&D, or demonstration purposes only. This licence authorises specific use at specific locations for a defined period. It does not permit commercial operation or sale.
| Characteristic | Detail |
|---|---|
| Purpose | R&D, testing, product evaluation, demonstration |
| Commercial use permitted? | No |
| Sale permitted? | No |
| Location-specific? | Yes - licence specifies the facility |
| Duration | Fixed term (typically 1-3 years, renewable) |
| Issuing authority | MIC Regional Bureau |
⚠️ The critical risk: Using a device under an Experimental Station Licence at trade fairs, client sites, or locations not listed in the licence creates Radio Act violations. The licence is not a general-purpose pre-certification permit.
The PSE / Radio Act Overlap
Many imported electronic devices require both PSE certification (under the Electrical Appliance and Material Safety Act / 電気用品安全法) and Radio Act 技適 certification. These are entirely separate obligations.
| Certification | Law | Authority | Scope |
|---|---|---|---|
| PSE (Diamond or Circle) | 電気用品安全法 | METI | Electrical safety of the device |
| Giteki (技適) | 電波法 | MIC | Radio frequency compliance |
A device with PSE certification but no 技適 cannot be legally operated if it has wireless capability. A device with 技適 but no PSE cannot be legally sold as an electrical appliance. Both are required independently.
Common Devices Requiring Both Certifications
| Device Type | PSE Required | 技適 Required |
|---|---|---|
| Wi-Fi router (plug-in) | Yes (Circle PSE) | Yes |
| Smart speaker | Yes (Circle PSE) | Yes |
| Wireless keyboard or mouse (battery-only) | No | Yes |
| Tablet with cellular | Yes (Circle PSE) | Yes |
| Industrial IoT gateway (AC power) | Yes (Circle PSE) | Yes |
| Bluetooth wearable (battery-only) | No | Yes |
FEFTA Intersection: Controlled Radio Equipment
Certain radio devices, particularly those with dual-use characteristics (military-grade encryption, satellite uplink, high-frequency spectrum capability), may also trigger FEFTA (外為法) pre-import clearance from METI in addition to Radio Act certification from MIC.
This dual-agency requirement applies when:
- The device appears on Japan's controlled goods import list under 外為法 第52条
- The device has technical specifications that satisfy the catch-all criteria under 外為法 推知規定
- The device is a satellite terminal with uplink capability (VSAT, LEO)
⚠️ When both MIC and METI approvals are required, the filings must reflect the same HS heading (FEFTA Consistency Rule per 外為法 第52条). Run HS classification and FEFTA assessment simultaneously, not sequentially.
Country-of-Origin Certifications: What They Do and Do Not Provide
| Certification | Jurisdiction | Valid in Japan? |
|---|---|---|
| CE mark (RED Directive) | EU | No |
| FCC ID | USA | No |
| IC (Innovation, Science and Economic Development) | Canada | No |
| KC mark | Korea | No |
| SRRC | China | No |
None of these certifications provide any legal basis for operating a wireless device in Japan. 技適 certification is not a mutual recognition arrangement with any of these schemes. A fresh Japan-specific certification is always required.
Import Process: Wireless Devices
Step 1: Identify all wireless capabilities
Review BOM, technical specifications, and firmware. Flag all RF-emitting modules
(Wi-Fi, BT, cellular, sub-GHz).
│
Step 2: Check MIC database for existing 技適 certification
If device/module already certified by manufacturer: confirm mark is present.
If not certified: initiate TELEC/JATE testing (6-12 weeks).
│
Step 3: Check for FEFTA applicability
Dual-use or controlled technology? METI clearance required before import.
Run HS classification in parallel with FEFTA assessment.
│
Step 4: Check PSE requirement
Does the device draw from mains power or have DC input?
If yes: PSE certification required (Circle or Diamond, depending on product category).
│
Step 5: Customs declaration
Import declaration via NACCS.
If 技適 pending: goods can be imported but cannot be operated until certified.
Experimental Station Licence: goods can be operated only at licensed locations.
│
Step 6: Post-import marking
技適 mark must be on device before sale or commercial demonstration.
Checklist: Wireless Device Import to Japan
- Identify all wireless protocols in the device (including embedded modules)
- Confirm whether existing 技適 certification exists in MIC database
- If not certified: engage TELEC or JATE testing laboratory, allow 6-12 weeks
- Determine if R&D or trial use is sufficient (Experimental Station Licence) or commercial sale is needed (技適)
- Run PSE assessment in parallel for devices drawing mains power
- Run FEFTA assessment for dual-use or controlled radio equipment
- Verify HS classification is consistent across NACCS declaration and any METI filings
- Confirm 技適 mark appears on device before sale or commercial demonstration
- Do not operate uncertified wireless devices at client sites, trade fairs, or public venues
