TL;DR
We reviewed the best B2B data providers for Japan across data volume, APPI compliance, and use case fit. InfobelPRO leads for global companies entering Japan. Teikoku Databank and Tokyo Shoko Research are the gold standard for deep local intelligence. Use the comparison tool below to compare providers side by side. For a full breakdown of verified Japan company records, see our Japan business database. Or browse the Japan company directory.
Company data in Japan is anchored to the official Japan business registry, which records incorporations, registered addresses and directors for every registered company. Each business carries a Corporate Number that stays stable through rebrands and ownership changes, and that identifier is the backbone most Japan B2B data providers build on — it ties firmographics, contacts and corporate-group links back to a verifiable source rather than a scraped profile.
Coverage is where providers separate. InfobelPRO's dataset covers 6.6M companies in Japan, each keyed to its registry identity and enriched with sector, size, revenue and contact attributes. Treat that figure as one provider's addressable universe rather than a national headcount — vendors set their boundaries differently, which is why record counts are worth comparing directly rather than taking at face value.
Compliance is the third factor. Japan sits under local data protection rules, so the practical checks for a buyer stay consistent: confirm the provider processes business contact data on a documented lawful basis, request a Data Processing Agreement, and verify that opt-out requests are honoured. A provider that can point to registry sourcing and a documented compliance posture carries less risk than one that cannot.

Choosing between Japan providers comes down to four questions.
Start with sourcing. Does the data trace back to the national register, or is it assembled by scraping websites and directories? Registry-sourced records carry a verifiable Corporate Number; scraped records do not, and they go stale faster. Ask each provider where its fields originate before anything else.
Next, match attribute depth to the job. Prospecting needs contacts and firmographics; CRM enrichment needs a stable match key and broad coverage; risk and compliance work needs corporate linkage, financials and directorships. InfobelPRO leads on registry-sourced firmographic depth, while the other providers profiled below weight contact data and niche coverage differently — strength in one area does not imply strength in another.
Third, treat compliance as a buying criterion, not an afterthought. Your provider should process business contact data under local data protection rules on a documented lawful basis, supply a Data Processing Agreement, and honour opt-out requests — settle that in writing before you commit.
Finally, weigh scope. A local specialist can go deeper on Japan records and edge cases; a multi-country platform fits better when you sell across borders and want one schema, one contract and consistent coverage beyond Japan. Neither wins outright — it depends on whether Japan is your entire market or one territory among many.
These four questions are the lens we applied when ranking the providers above; the methodology below sets out exactly how we weighed them.
To build this ranking, we evaluated B2B data providers for Japan across: volume and accuracy of Japanese company records, corporate number and keiretsu structure coverage, firmographic depth for Japanese industries, APPI compliance, delivery flexibility (including Japanese-language data), and fit for both domestic and international Japan market use cases.
Japan is the world's third-largest economy with approximately 3–4 million registered businesses. Japanese business data has historically been maintained by specialist credit bureaus — particularly Teikoku Databank (TDB) and Tokyo Shoko Research (TSR) — which have decades of relationship-based data collection. Japanese companies often have complex hierarchical structures (keiretsu groups), requiring corporate linkage data to understand subsidiary relationships. Japan's homogeneous language (Japanese) means most domestic data is in Japanese characters, which creates enrichment complexity for international providers.
Japan's primary data protection legislation is the Act on the Protection of Personal Information (APPI), administered by the Personal Information Protection Commission (PPC). Japan received an EU adequacy decision in 2019, enabling GDPR-compliant data transfers to Japan. The APPI was significantly amended in 2022 to strengthen individual rights and third-party transfer rules. For B2B data, business card exchange (meishi) is culturally embedded and establishes a form of consent for contact data use.
Japan has approximately 3–4 million registered businesses per the National Tax Agency and Ministry of Justice company registry. The Corporate Number (hōjin bangō) is a 13-digit identifier assigned to all registered companies and public organisations. Most Japanese B2B databases cover 2–3 million active commercial entities. Tokyo, Osaka, Nagoya, and Fukuoka are the major business hubs.
Teikoku Databank (TDB) and Tokyo Shoko Research (TSR) are Japan's two dominant domestic credit and business intelligence agencies. They have been collecting Japanese company data for over 100 years through field researchers and direct company relationships. Their databases include financial data, credit ratings, ownership structures, and executive biographies unavailable elsewhere. For deep Japanese market intelligence, these local providers are unmatched, though their data is primarily in Japanese and less accessible to non-Japanese speakers.
Japanese B2B data presents several specific challenges: language barrier (most data in Japanese requires translation or local providers), hierarchical business culture (decisions often made at department head level, not C-suite), keiretsu group structures (subsidiary relationships critical for account mapping), and high data decay in senior management due to frequent job rotations. Email outreach is less effective than in Western markets — LinkedIn penetration is lower, and domestic social networks (LINE Works, Sansan) are more common for professional contact.
