JC-STAR: STAR-1 vs STAR-2 — Which Level to Choose for Your IoT Product?

Editor:ESTL Category:Technical information Release time:2026-04-13 Click volume:7

After gaining a deep understanding of the JC-STAR framework, the top question for most manufacturers is:Should my product start with STAR-1 or STAR-2?As your first step into the Japanese market, choosing the right basic level not only saves cost and speeds up progress but also lays a solid foundation for future development.This article focuses on STAR-1 and STAR-2 to provide clear logic and implementation paths for level selection.

I. Core Interpretation: Positioning & Value of Basic Levels

JC-STAR is led by Japan’s Ministry of Economy, Trade and Industry (METI) and administered by the Information Processing Promotion Agency (IPA), establishing a security trust mark for IoT products.For most manufacturers, starting with a basic level is the most practical approach.

Core Value:Both STAR-1 and STAR-2 are certified via self-declaration of conformity,making them the most cost-effective and time-efficient market access solutions.

II. Precise Positioning: How to Choose Between Basic Levels

To select the best starting level for your product, consider these dimensions:

(1) Target Market & Customer Requirements

STAR-1: For general consumers; meets minimum security requirements.
STAR-2: For corporate clients or commercial scenarios with specific security demands.

(2) Product Risk Level

Low-risk products: Smart home sensors, basic small home appliances → STAR-1 recommended
Medium-risk products: IP cameras, smart door locks, routers → STAR-2 recommended

(3) Expected Resource Investment

STAR-1: Short preparation cycle, relatively low internal resource input.
STAR-2: Requires more complete technical documentation and enhanced security measures.

III. Practical Guide: Level Recommendations for Typical Products

表格

Product Category	Typical Examples	Recommended Level	Key Reasons & Support
Consumer Smart Home	Smart lights, smart plugs, basic sensors	STAR-1	Standard self-declaration package available
Security Devices	IP cameras, smart locks, routers	STAR-2	Enhanced requirement guidance provided
Commercial Equipment	Office IoT devices, commercial sensors	STAR-2	Customized solutions available
Wearable Devices	Fitness bands, basic smart watches	STAR-1	Fast-track service supported

Note on higher levels:STAR-3 and STAR-4 target government and critical infrastructure sectors,requiring strict assessment by IPA-approved third-party laboratories.

IV. Manufacturer FAQs: Basic Levels

Q1: What is the main difference between STAR-1 and STAR-2?

A: STAR-1 is the mandatory minimum security baseline for all IoT devices.STAR-2 adds product-specific security requirements on top of STAR-1.We can help you identify these differences precisely to avoid over- or under-preparation.

Q2: Does self-declaration mean “easy to pass”?

A: No. Self-declaration requires a complete chain of conformity evidence,and the IPA conducts strict format reviews.We offer pre-submission document review to greatly improve first-time approval rates.

Q3: Will choosing a basic level affect market competitiveness?

A: No. STAR-1 and STAR-2 already meet the purchasing requirements of most Japanese commercial and consumer markets,making them the most cost-effective choice.
