Direct answer: Japan’s Electrical Appliances and Materials Safety Act regulates covered electrical products and requires the responsible business operator to complete the applicable notification, conformity, inspection, recordkeeping and PSE labeling steps before sale. From 25 December 2025, new rules also affect overseas businesses selling covered products directly to consumers in Japan.

Existing PSE responsibilities
METI states that covered manufacturers and importers must notify the business, confirm conformity with technical requirements, conduct self-inspection and keep records. Specified Electrical Appliances and Materials require conformity assessment by a registered body. PSE labeling can be applied only after the relevant obligations are fulfilled.
Direct-to-consumer overseas sales
Japanese regional METI guidance explains that, from 25 December 2025, an overseas business selling PSE-covered products directly to Japanese consumers must follow the designated-import-business framework and appoint a domestic administrator. The exact route depends on who imports and places the product on the Japanese market.
What this means for humidifiers, fans and diffusers
- Classify the complete product and every supplied mains adapter or power component.
- Confirm which Japanese party is the responsible importer or designated business operator.
- Review the Japanese technical requirements, inspections, records and markings for the exact item.
- Prepare Japanese instructions, warnings and product identification.
- Do not apply a PSE mark based only on a component certificate or an unrelated model.
MistAirHome sourcing note
For Japan, the buyer and factory should agree in writing on the product classification, responsible business operator, adapter, battery, markings, Japanese documentation and required evidence before approving production.

Questions from buyers
Customer FAQ
Does every electrical product sold in Japan require a PSE mark?
Only products within the scope of Japan’s Electrical Appliances and Materials Safety Act follow the applicable PSE route. The exact product category, electrical design and supply model must be classified before applying any mark.
Can an overseas seller put the PSE mark on a product by itself?
No. The responsible business must first complete the applicable notification, conformity, inspection and recordkeeping obligations. The mark cannot be used merely as a marketing label.
What should a Japanese buyer provide for OEM packaging?
Provide the approved Japanese company details, required Japanese warnings and instructions, model classification, electrical ratings and final compliance text. MistAirHome will align artwork to the approved specification before mass production.
