Wireless product access to Japan — the industry calls it TELEC or MIC certification, some say Giteki. Same thing: type approval for wireless equipment under the Radio Act. Without it, you can't enter the Japanese market, and customs will hold your shipment. The Ministry of Internal Affairs and Communications (MIC) oversees it, with registered certification bodies (RCB) doing the actual work. The Radio Act saw significant changes in 2026 — anyone doing Japan wireless compliance needs to pay attention.
Let's clear up a common trap first: TELEC certificates don't have a fixed 3-year expiry. The certificate is valid long-term. When does it lapse? When you change hardware or RF firmware, or when MIC updates appendix standards and the transition period expires. The "3-year renewal" rumor floating around is false. If the product hasn't changed and standards haven't shifted, the certificate stays valid.
2. Top-Level Framework and Appendices
Notice No.88 Is the Master Standard
Japan's unified wireless equipment standard under the Radio Act is MIC Notice No.88, organized by appendices for different frequency bands and wireless types. Standards keep evolving, but certificates obtained during the transition period remain valid. From April 2026, new applications must use the latest appendices — but that doesn't mean all old reports are voided.
2.4GHz — Appendix 43
Bluetooth and 2.4GHz WiFi fall under Appendix 43, referencing ARIB STD-T66. Testing covers frequency error, transmission power, occupied bandwidth, spurious emissions, and receiver interference immunity. EIRP limit is 100mW, with a minimum of 75 hopping channels for frequency-hopping devices.
Channel 14 (2471-2497MHz) is a trouble spot: if the hardware enables Channel 14, you must run additional Appendix 44 specific testing. But if Channel 14 is software-disabled and only channels 1-13 are used, Annex 44 isn't required. This depends on actual channel configuration — don't get swept up by one-size-fits-all claims.
5GHz — Appendix 45
5GHz WiFi maps to Appendix 45, where DFS radar avoidance is mandatory. The W56 band (5.6GHz) faces tighter scrutiny this year, but this only applies to devices with 80MHz and 160MHz bandwidth. DFS requirements for 20MHz and 40MHz haven't changed. Confirm bandwidth specs with your lab before submission.
6GHz Spectrum Status
The 6GHz band currently only opens 5925-6425MHz. Frequencies above 6425MHz aren't commercially available yet. The AFC database system hasn't launched in Japan either. LPI at 23dBm is limited to indoor use; VLP at 14dBm doesn't need AFC — for the simple reason that AFC doesn't exist yet, not because VLP has some special exemption.
Cellular and Low-Power Devices
2G, 4G, and 5G cellular products correspond to separate MIC appendices, plus you need carrier approval on top. Handheld devices require SAR testing. Low-power short-range devices fall under Appendix 49 — 433MHz and 868MHz may qualify for exemption under certain conditions, but you need to verify power levels item by item.
Automotive Wireless — Appendix 50
Automotive wireless maps to Appendix 50. One standard number gets misused constantly: JIS D0203 covers waterproof and humidity testing, not thermal shock or vibration. Vibration testing corresponds to JIS D 1601. Also, high/low temperature and vibration tests are OEM reliability requirements, not MIC mandatory tests. TELEC certification itself doesn't require the -30 to 85 degree cycling.
3. Universal Required Tests and 2026 Additions
Frequency accuracy, transmission power, occupied bandwidth, and spurious emissions apply to all wireless devices. Human exposure assessment depends on use case — fixed installations use MPE, while handheld and wearable devices require SAR testing.
On the EMC side, VCCI is Japan's mandatory整机 EMC requirement — it's not optional. TELEC covers RF emissions; VCCI covers conducted emissions from 150kHz to 30MHz. Two separate systems, each managing their own domain.
Starting February 14, 2025, wireless products with USB-C ports face an additional test. The new regulation tests RF interference during USB-C charging — essentially RF spurious emissions. Don't confuse this with PSE electrical safety testing. The MIC Radio Act tests RF only, never safety.
For labeling, JIS C 9913 allows QR codes to display Giteki information. Amazon Japan has been checking aggressively this year — products must display the Giteki number or face immediate delisting. Maximum penalty for violations is 100 million yen. Take it seriously.
4. MIC Certification Types and Timeline
Type Certification vs. Single Unit
Mass production manufacturers should go with type certification — one approval covers the entire model batch. Single unit certification only suits small sample quantities, costs more, and can't be reused.
Agent Requirements and Review
Overseas manufacturers must appoint a Japan-based local agent to submit applications. After market entry, a Japan domestic responsible party must be designated for market surveillance cooperation. Pure lab RF testing takes 2 to 3 weeks. RCB review adds another 1 to 2 weeks. If rework and retesting are needed, the total cycle stretching to 4 to 6 weeks is normal.
The top priority for MIC certification is matching the correct appendix to your actual frequency band. Get the appendix wrong and everything after is wasted effort. Standard version, channel configuration, and spectrum open status — verify these three before submission. Takes minutes, saves massive headaches.
