If your smart cameras, industrial routers, smart home, or energy storage devices are planning to enter the Japanese market, have you realized that a new door is opening, but at the same time, a new "security checkpoint" has been set up? In 2025, JC-STAR (Japan Cyber Security Technical Requirements for Secure IoT Devices Conformity Assessment and Labeling Scheme), promoted by the Japanese government and implemented by the Information-technology Promotion Agency (IPA), will be officially launched. This is not only a domestic security standard in Japan but also a "new entry ticket" for global IoT manufacturers to compete in the Japanese market. Understanding it means seizing opportunities; ignoring it may mean missing out on Japan's government procurement, critical infrastructure, and high-end markets.

I. What is JC-STAR? An Official IoT Security "Certification Mark"

Simply put, JC-STAR is a cybersecurity conformity assessment and labeling system established for IoT products.

1. Official Background: Supervised by Japan's Ministry of Economy, Trade and Industry (METI), with the authoritative IPA as the certification and label issuing agency.

2. Core Form: Issue "conformity labels" with star ratings (1-4 stars) to IoT products that meet security requirements.

3. Legal Basis: Based on the Information Processing Promotion Act, aiming to ensure the security and reliability of information processing at the technical level.

This is not just a technical standard, but also an important national policy for Japan to build a security defense line for its digital economy.

II. Why Was JC-STAR Launched? Three Drivers Reveal Market Future

The launch of JC-STAR is an inevitable result of market demand and policy drivers, mainly stemming from three reasons:

1. Address Surging Cybersecurity Threats: With the explosive growth in the number of IoT devices, their security vulnerabilities have become a breeding ground for hacker attacks. Japan urgently needs to raise the IoT security baseline of the entire society.

2. Unify Procurement Standards and Facilitate Buyer Identification: For purchasers such as the Japanese government, critical infrastructure (e.g., power, water utilities), and large enterprises, it was previously difficult to judge product security performance. The JC-STAR label provides a clear and credible screening standard.

3. Align with International Standards and Create a Japanese Solution: Globally, similar systems such as the EU's ETSI EN 303 645 and the UK's PSTI have been successively launched. JC-STAR is an officially endorsed "local voice" from Japan in the field of international IoT security standards.

For manufacturers, this means that a JC-STAR label is a "quality declaration" for Japan's high-end procurement market.

III. How Does It Differ from International Standards Such as ETSI EN 303 645 and PSTI?

Many IoT manufacturers may have come into contact with the EU's ETSI EN 303 645 and the UK's PSTI Act. JC-STAR is aligned with them but has unique characteristics, which can be understood as "an access scheme officially launched by Japan that integrates international requirements and has local procurement characteristics."

Core Differences and Value:

JC-STAR has clear official endorsement and a hierarchical evaluation system. It directly "translates" internationally accepted security requirements into "credentials" recognized and mandatorily procured by the Japanese market. Simply put, if your products are already prepared to meet ETSI EN 303 645 or respond to PSTI, you have already completed most of the work for JC-STAR (especially STAR-1). JC-STAR provides you with a clear path to convert internationally common compliance into a specific competitive advantage in the Japanese market.

IV. What Does It Mean for Manufacturers? Challenges, and More Importantly, Opportunities!

1. Challenges: Need to invest resources in compliance assessment, which may involve adjustments to product design and software development processes, and incur certain certification costs.

2. Opportunities (More Important):

   1. Market Access: A "stepping stone" or even a "mandatory requirement" to enter the procurement lists of the Japanese government and critical infrastructure.

   2. Brand Premium: Significantly enhance the product's security image and competitiveness in the Japanese market, distinguishing it from uncertified products.

   3. Preparation for the Future: Conform to the global trend of IoT security regulation, layout in advance, and accumulate experience to respond to similar requirements in other countries.

It can be said that proactively responding to JC-STAR now is a preemptive move for Japan's market share in the next 3-5 years.

V. How Should I Start? First Action Suggestions

It is normal to feel at a loss when facing a new regulation. We recommend taking the following steps:

1. Self-Assessment: Confirm whether your products (e.g., network cameras, routers, smart home gateways, sensors, etc.) fall within the scope of JC-STAR.

2. Study Ratings: Initially determine which level of label your product's target market requires (STAR-1 as the basic level, STAR-3/4 for high-end procurement).

3. Seek Professional Advice: Conduct preliminary communication with experts or evaluation agencies familiar with the system to assess the gap and workload.

The arrival of JC-STAR marks that Japan's IoT market has entered a new stage of "certified access". It is not only a strict test of product security but also an excellent stage for manufacturers to demonstrate their strength and gain trust. At the starting point of this new track, understanding earlier and preparing sooner will allow you to gain an absolute advantage in future market competition.
