Improving the UI and Expanding Data Fields for Provisional Company Listings The National Company Database（$CDB）provides provisional company listing pages to make company information across Japan more widely accessible. The provisional company data can be viewed from the following page: companydata.tsujigawa.com/co… Currently, CDB is expanding the comprehensiveness of its corporate information by publishing company data from across Japan as provisional listings, in addition to already registered companies. This makes it easier for users to search and verify a wider range of companies based on basic information such as company name, location, and corporate number. Going forward, CDB plans to further improve the user interface of these provisional company data pages. We will work on enhancing the search result listings, company detail pages, mobile display, and information block layouts so that users can access the company information they need more smoothly and intuitively. In addition, CDB will gradually expand the types of company information collected and displayed. Beyond the current basic information, we plan to enhance data fields such as location details, corporate classification, update information, related data, and information useful for credibility verification. Through these improvements, CDB aims to evolve from a simple company listing site into a more practical and valuable corporate information database. The provisional company data serves as an important foundation for the future growth of CDB. By increasing the number of listed companies while improving the UI and expanding available data fields, CDB will continue to enhance searchability, usability, and information reliability. CDB aims to become a more useful and valuable corporate information platform for users searching for companies, businesses verifying potential partners, and companies seeking to communicate their own information more effectively.

CDB Significantly Expands Its Information Coverage by Adding Approximately 5.56 Million Provisional Company Records The National Company Database（ $CDB ）has newly added 5,564,837 company records from across Japan as “provisional company listings,” in addition to the 3,888 registered companies already published on the platform. Through this major data expansion, the range of company information available on CDB has been significantly broadened, creating an environment where users can access information on a wider variety of entities, including listed companies, SMEs, regional businesses, and other corporate organizations. Provisional company pages are designed differently from officially registered company pages. They serve as foundational data pages intended to make company information more accessible to a wider audience. As a result, users can more easily find target companies based on basic information such as company name, location, and corporate number. Improving Searchability by Covering Company Information Nationwide Until now, CDB has mainly published information on registered companies. With the addition of provisional company data, however, the platform’s coverage has expanded significantly on a nationwide scale. This improvement is expected to enhance the overall usability of CDB by supporting a wider range of search needs, including company name searches, regional searches, business category searches, corporate name searches, and corporate number searches. In addition, the increased number of company listings improves the comprehensiveness of information within the site, helping users reach the information they are looking for more easily. Expected Access Growth Through Expanded Google Indexing The newly added provisional company pages also play an important role as indexable pages for search engines such as Google. By creating individual pages for companies across Japan, CDB can expect increased traffic from long-tail search keywords, including company name searches, regional company searches, and corporate number searches. Company information is a field with continuous and stable search demand. Therefore, an increase in the number of published pages does not simply mean a larger amount of information; it also creates more entry points from search engines. As a result, this expansion is expected to have a positive impact on CDB as a whole, including increased overall access, greater platform recognition, and more internal traffic to existing registered company pages. Strengthening Pathways Toward Official Company Registration The addition of provisional company pages is not only about publishing company information. It also creates an opportunity for companies to discover their own pages, review their listed information, and proceed to official registration or verification if needed. CDB provides not only company information listings but also features that support corporate credibility and information distribution, including verification systems, press release publication, and enhanced company profile pages. Companies listed as provisional entries can develop their pages into more accurate and trustworthy company profiles by completing official registration or updating their information. Ripple Effects on the Native Token “ $CDB ” The addition of approximately 5.56 million provisional company records is significant not only for improving CDB’s information volume, searchability, and platform value, but also for the native token “$CDB.” As the number of listed companies on CDB increases substantially, search engine traffic, on-site circulation, and company page views are also expected to grow. This may lead to expanded usage opportunities across the broader CDB ecosystem. In the future, by connecting “$CDB” with various functions within the platform—such as company information access, verification systems, press release distribution, advertising, company page enhancement, and data integration—it will become possible to expand the token’s utility use cases. Furthermore, as the scale of the company database grows, the practicality and recognition of the CDB platform are expected to increase. This can help position “$CDB” not merely as a token, but as a utility token connected to a real-world corporate information infrastructure. Going forward, CDB plans to gradually expand the use cases of “$CDB” alongside improvements in company data coverage, verification systems, press release publication, and business-oriented platform features. This large-scale data expansion represents an important step not only for the growth of the CDB platform itself, but also for enhancing the utility value of the broader CDB ecosystem and its native token, “$CDB.” Toward Further Growth as a Corporate Information Platform Through this large-scale data expansion, CDB will continue to evolve beyond a simple company listing site into a corporate information platform where users can search, verify, and share company information from across Japan. CDB will continue working to improve the accuracy of company information, enhance search functionality, improve the usability of company pages, and strengthen traffic acquisition from Google Search. By making more company information easier to access and understand, CDB aims to support company discovery, comparison, credibility verification, and corporate information distribution.
