Japan’s Ministry of Economy, Trade and Industry (METI) announced on May 15, 2026, that the PSE certification exemption for Matter-enabled smart lighting products will be terminated effective October 1, 2026. This policy shift directly affects LED drivers, smart bulbs, and dimming controllers using Matter connectivity — all of which will now require individual PSE certification for local control functionality. Exporters of lighting OEM products from China to Japan, as well as manufacturers and distributors engaged in this supply chain, must assess implications for compliance timelines, testing costs, and market access.
On May 15, 2026, Japan’s Ministry of Economy, Trade and Industry (METI) confirmed the termination of the PSE certification exemption for smart lighting devices compliant with the Matter protocol. Starting October 1, 2026, all Matter-connected LED drivers, smart bulbs, and dimming controllers sold in Japan must obtain separate PSE certification covering local control functionality, issued by METI-designated conformity assessment bodies.
Manufacturers exporting smart lighting products from China to Japan are directly impacted, as their current PSE-exempt Matter-certified products will no longer qualify for market entry without additional local control verification. The requirement introduces new test scope (e.g., offline operation, local command responsiveness, firmware isolation), extending certification lead times and increasing third-party testing fees.
Suppliers providing core components — especially integrated drivers or wireless control modules embedded in Matter-compliant luminaires — may face revised qualification demands. If these components implement local control logic, they may need standalone PSE evaluation or co-certification with end products, affecting bill-of-materials planning and technical documentation handover.
Importers and Japan-based brand owners responsible for product registration and PSE marking must verify whether existing inventory or incoming shipments meet the new requirement. Products certified under the previous exemption framework will not be grandfathered; post-October 1, 2026, non-compliant stock cannot be legally placed on the Japanese market.
METI has not yet published detailed technical criteria for ‘local control functionality’ under PSE. Companies should track announcements from METI and accredited bodies (e.g., JET, UL Japan, TÜV SÜD Japan) regarding test standards, sample requirements, and transitional arrangements — particularly whether limited pre-October submissions will be accepted.
Focus initial compliance efforts on products where local control is implemented via embedded firmware (e.g., Matter-over-Thread bulbs with onboard commissioning), rather than cloud-dependent models. Prioritize items already scheduled for Japan shipment between August–September 2026 to avoid clearance delays.
The October 1, 2026, date marks a formal regulatory deadline, but customs enforcement capacity and inspector training timelines remain unconfirmed. While compliance is mandatory from that date, practical enforcement ramp-up may vary — making early engagement with Japanese import agents and certification consultants advisable.
Allocate additional 8–12 weeks for PSE certification cycles due to added local control testing. Update internal product development roadmaps to include parallel PSE preparation alongside Matter certification — especially for new SKUs targeting Q4 2026 launch windows.
This measure is best understood not as an isolated regulatory update, but as a signal of Japan’s broader alignment with functional safety and resilience expectations for connected devices. Analysis shows METI is reinforcing domestic control requirements in response to growing emphasis on data sovereignty, interoperability reliability, and offline usability — trends also visible in recent EU Cyber Resilience Act provisions. Observably, the timing coincides with global Matter 1.3 adoption, suggesting Japan is calibrating its certification framework to match evolving protocol capabilities. From an industry perspective, this is less a sudden barrier and more a formalization of an emerging expectation: Matter compliance alone no longer suffices for Japanese market access — local control assurance is now a distinct, mandatory layer.

Conclusion: The termination of the Matter exemption reflects a tightening of technical accountability for smart lighting in Japan — shifting responsibility from protocol-level conformance to device-level functional assurance. It does not invalidate Matter adoption but requires layered compliance planning. Currently, this development is most accurately interpreted as a procedural escalation with clear operational consequences, rather than a strategic pivot away from Matter. Companies should treat it as a fixed timeline requirement demanding structured technical and logistical preparation — not a negotiable or optional adjustment.

Details regarding test specifications, designated bodies’ implementation timelines, and potential transitional allowances remain pending further METI publications and are subject to ongoing observation.
