In Japan, selling an electrical product without PSE certification is not a regulatory grey area. It is a criminal offense — one that can result in fines of up to 100 million yen for corporate entities and one year of imprisonment for individuals.
Most importers and brand managers learn about PSE certification as a checklist item. What the data reveals is that even established Japanese companies with decades of market presence get it wrong — and the consequences are visible, public, and permanent.
What PSE Certification Actually Requires
PSE stands for the Product Safety Electrical Appliance and Materials Act (電気用品安全法, DENAN). It is Japan’s mandatory certification framework for electrical products, administered by the Ministry of Economy, Trade and Industry (METI).
Any electrical product sold in Japan — online or offline, imported or domestically produced — must carry the PSE mark. There are two mark types: a diamond mark (丸PSE) for lower-risk products where manufacturers self-certify, and a circle mark (菱形PSE) for higher-risk products such as air conditioners, televisions, and electric water heaters, which require third-party certification by a registered inspection body.
Without the correct PSE mark, products cannot legally be placed on the market. Distribution platforms operating in Japan are required to screen for PSE compliance, and METI conducts annual market surveillance specifically targeting non-compliant products.
The Compliance Numbers Are Stark
METI’s annual market surveillance results provide a useful measure of how common non-compliance is. In fiscal year 2021, 176 products were purchased and tested; 50.6% were found non-compliant. In fiscal year 2022, 163 products were tested; 49.7% were non-compliant.
Approximately half of sampled electrical products in Japan fail safety compliance checks. This is not a market populated primarily by unknown or low-quality imports. It includes products from established brands.
Three Real Cases from 2022
The following three cases are drawn from public METI and NITE records. All involve recognizable brands — two of them major Japanese companies with generations of brand equity in their home market.
Tiger Corporation (タイガー魔法瓶) — 2022
Tiger Corporation, one of Japan’s most recognized kitchen appliance brands, was required to recall electric kettles and rice cookers after METI found that the magnetic detachable power cord plugs used in a product line did not meet PSE technical standards. The affected products had been sold from March 2020 through February 2022 — a two-year period. Tiger Corporation’s name was published on the METI website.
The nature of the violation is significant: this was not a counterfeit product or a low-quality import. It was a manufacturing decision by a domestic brand that did not hold up under METI’s technical standards review.
Haier Japan (ハイアールアジア) — 2022
Haier Japan, the Japanese subsidiary of the Chinese appliance manufacturer, recalled 52,092 rice cookers sold between November 2018 and April 2022. The recall was triggered by findings that components in the affected units had not undergone required PSE testing, creating a fire risk. The scale of this recall made it one of the most significant PSE-related actions of 2022.
The case illustrates a specific failure mode: PSE is not a one-time certification. Components used in products must themselves meet technical standards, and changes in component sourcing or specifications can trigger new compliance requirements.
Zojirushi (象印マホービン) — 2022
Zojirushi, another well-established Japanese kitchenware manufacturer, recalled 7,056 electric griddles after METI and the National Institute of Technology and Evaluation (NITE) jointly identified a micro-current issue during long-term use — a condition that does not meet PSE technical standards. The recall included full refunds. Both METI and NITE published the case.
The Zojirushi case is particularly instructive because the issue was identified through long-term use testing. Products that pass initial compliance checks can still develop characteristics over time that bring them out of compliance.
What Happens When Non-Compliance Is Found
METI has two primary enforcement tools beyond recalls. First, the agency publishes the names of non-compliant companies and products on its official website. This public naming persists — a company’s history of PSE violations is accessible to any buyer, distributor, or retail platform conducting due diligence. Second, for persistent or severe violations, METI can issue administrative orders, seizure orders, and refer cases to prosecutors for criminal charges.
For foreign brands and importers, there is an additional complication: Japan requires a domestic registered import agent (届出事業者) for many PSE-certified product categories. The agent is legally responsible for confirming compliance. If a product is recalled or found non-compliant, the registered agent shares legal exposure.
High-Frequency Violation Categories
METI’s surveillance data consistently identifies certain product categories with elevated non-compliance rates:
- Chargers and mobile power banks (consistently the highest-frequency category)
- LED lighting products
- AC adapters and power supplies
- Rice cookers and small domestic appliances
These categories cover a significant portion of the consumer electronics products most commonly considered for Japan market entry by Chinese and Southeast Asian manufacturers.
The Practical Implication
The Tiger and Zojirushi cases make one point clearly: PSE compliance is an ongoing operational responsibility, not a box checked during initial product registration. Domestic brands with long market histories still face recalls when manufacturing processes change or long-term performance characteristics emerge.
For foreign brands entering Japan, this means PSE certification requires not just initial compliance documentation but processes for ongoing monitoring, component change management, and registered agent oversight.
The question is not whether PSE compliance is necessary. It is whether the process is properly structured before products reach the market — not discovered after METI’s annual surveillance does.

Frequently Asked Questions
Q: Is PSE certification mandatory for all electrical products sold in Japan?
A: Yes. The Product Safety Electrical Appliance and Materials Act (DENAN) requires all electrical products sold in Japan — online or offline, imported or domestically made — to carry the PSE mark. There are two types: a circle mark for self-certified lower-risk products, and a diamond mark for higher-risk products requiring third-party inspection. Selling without the correct mark is a criminal offense.
Q: What are the penalties for PSE non-compliance in Japan?
A: Corporate entities face fines of up to 100 million yen. Individuals face fines of up to 1 million yen plus up to one year of imprisonment. Beyond financial penalties, METI publicly names non-compliant companies on its official website — reputational damage that persists and affects distributor and retail relationships.
Q: What product categories have the highest PSE non-compliance rates in Japan?
A: Based on METI annual market surveillance data (FY2021-2022), the highest-frequency violation categories are: (1) chargers and mobile power banks, (2) LED lighting products, (3) AC adapters and power supplies, and (4) rice cookers and small domestic appliances. METI found approximately 50% non-compliance rates in sampled products across FY2021 and FY2022.
Q: Do Japanese companies also fail PSE compliance?
A: Yes. In 2022, Tiger Corporation recalled electric kettles and rice cookers for PSE non-compliance, Zojirushi recalled 7,056 electric griddles, and Haier Japan recalled 52,092 rice cookers. All cases are publicly documented on METI and NITE records. PSE compliance is an ongoing operational requirement, not a one-time certification.
