One is optional market credibility; the other is a binding efficiency requirement with a genuinely unusual moving-target methodology.

No — JIS Mark certification is voluntary. It signals conformity to a specific Japanese quality/performance standard and can support market credibility or procurement requirements, but it isn't a market-access gate the way PSE electrical safety or TELEC radio certification is. ### How is Top Runner different from a fixed energy-efficiency threshold? Top Runner sets its efficiency standard based on the current best-performing product in the market rather than a fixed numeric target set once and left static — the requirement effectively rises as the market's own top performers improve, pushing continuous efficiency gains rather than a one-time compliance bar. ### Which product categories are covered by Top Runner? The program covers a defined set of energy-consuming product categories — televisions, refrigerators, air conditioners, computers, and similar covered appliances/electronics — set out under the Energy Conservation Act. Confirm your specific product category's current coverage status and target year against METI's current Top Runner list. ### Do retailers have compliance obligations under Top Runner, or just manufacturers? Retailers can have sales-data reporting obligations for covered energy products, separate from the manufacturer's efficiency-target and labeling obligations — factor this into planning if you're working through Japanese retail partners rather than direct sale. **Disclaimer:** Educational resource only.
