Verify the facts in Japan — in your own language.

• Online Reputation Check

  We investigate a Japanese individual's social media, forums, and blogs to check their online reputation and any history of trouble.

• Employment & Education Verification

  We verify, through lawful means, whether the career and academic history claimed by a fiancé(e), business partner, or job candidate is true.

• Company Legitimacy Check

  We confirm that a Japanese company you plan to deal with actually exists and is operating, using corporate registry records and an on-site visit.

• Partner & Fiancé(e) Check

  Before an international marriage or relationship, we verify your Japanese partner's marital history and living situation to protect you from marriage and romance scams.

• Business Partner & Investment Check

  Before investing in or partnering with a Japanese company, we investigate the reputation of its executives and any history of lawsuits or bankruptcy.

• Whereabouts Check

  We locate, within lawful limits, a business contact or acquaintance in Japan who has stopped responding.

Text-based communication means nothing gets lost in translation

All communication is in writing via chat and email, so we can respond accurately to inquiries in Japanese, English, and Chinese, and a full written record of every exchange is kept.

No visit to Japan, no phone calls required

Consultation, contract, and reporting are all completed via chat and email. No phone or video call appointments are needed. Your report is delivered as a PDF.

Transparent pricing, fixed quote before we start

The scope and fee are confirmed in writing before any work begins. If additional costs arise, we always consult you first.

• Payments from overseas are accepted by bank transfer (in Japanese yen) and credit card.

Hello, I am Komura, the founder of Tokyo Komura Detective Agency. This is an independent, one-person detective agency specializing in clients living overseas and foreign residents of Japan. As international marriages and cross-border business become commonplace, more and more people find themselves wanting to verify someone in Japan but blocked by language and distance. I opened this agency to remove those barriers. Because the agency is small, I personally handle everything from your first message to the final report — and because all communication is in writing, language is never an obstacle.
