Nittan

What Nittan does

Nittan (株式会社ニッタン) is a privately held Japanese corporate investigation and information-gathering services firm incorporated in October 1966 and headquartered in Osaka's Kita-ku (Umeda) business district. The company provides professional research and investigative services to approximately 2,000 corporate clients spanning banks, enterprises, schools, unions, and law firms. Its core offering is delivered through two channels: (1) Research/Investigation Services (調査サービス), performed by a small team of seasoned in-house professionals supplemented by commissioned part-time investigators, and (2) the Brains Club (ブレーンズクラブ) membership program, which provides repeat clients with discounted fees, business seminars, and free professional referrals.

The business model is B2B sales-led, with free initial consultations and quotes and no consultant travel charges. Revenue is generated on a pay-as-you-go professional services basis, with full-time sales staff compensated through fixed salary plus performance bonus and part-time investigators compensated purely on commission, enabling the cost base to flex with engagement volume. Customer acquisition relies on direct sales and referrals from the established ~2,000-account base rather than active digital or performance marketing. The company is privately held with no disclosed institutional investors, parent entity, or subsidiaries; registered capital is 10 million yen.

Nittan's geographic footprint is concentrated in the Kansai region of Japan with no claimed international operations. Its digital presence is dated — the company website uses Flash content and carries a 2000–2018 copyright, and no mobile apps, APIs, integrations, or AI/ML capabilities are present in the offering. Operational banking is supported by three named Japanese megabank branches (Sumitomo Mitsui, MUFG Nakanoshima, Mizuho Osaka), reflecting standard commercial banking infrastructure rather than strategic financial partnerships. The firm explicitly declines investigations related to buraku discrimination or human rights violations, signaling a compliance-conscious, ethically scoped service perimeter.
