SBI Nihon SSI

What SBI Nihon SSI does

SBI Nihon SSI (SBI日本少額短期保険株式会社) is a Japanese licensed small-amount short-term insurer (少額短期保険業者, Kinki Finance Bureau registration No. 3) that underwrites three core insurance verticals: rental housing insurance (みんなの部屋保険, みんなのテナント保険), motorcycle vehicle insurance (みんなのバイク保険, with brand-specific variants for Harley-Davidson and Triumph), and bicycle/e-bike insurance (みんなのスポーツサイクル保険, みんなのe-bike保険, すぽくるプラス, MATE. partnership). The company was established in April 2008 as NJI-日本住宅少額短期保険株式会社, joined the SBI Group in 2010, and rebranded to its current name; it is a wholly-owned subsidiary of SBI Holdings. Operations are headquartered in Osaka with additional offices in Tokyo, Fukuoka, and Hiroshima, employing 11-50 staff.

The company's core technology is the proprietary "Nico" insurance contract management system, an OAuth2.0-based API platform that enables real estate platforms (ITANDI, Chinta Revolution 10), rent guarantee companies (J:Lease, Alpha, Zenporen, ひろぎんクレジットサービス), and property management software providers to embed insurance application functionality directly into their workflows. The system supports paperless (eco証券 digital certificates) and cashless processing, operates 24/365, and serves 16+ integration partners as of October 2025. The "eco証券" (eco Insurance Certificate) system provides paperless policy management that has been operational since 2011.

The business model operates on three revenue streams: (1) direct underwriting premiums from own insurance products (recurring subscription), (2) agency/broker commissions for distributing third-party products including AXA motorcycle insurance, AU Sompo bicycle insurance, and other SBI Group products (SBI Life, SBI Sonpo auto, SBI Prism pet, SBI Pet, SBI Resta earthquake, SBI Ikiki medical/life/care), and (3) API-driven embedded distribution revenue through real estate platforms. GTM is multi-channel: direct-to-consumer internet sales (24/7 online application), real estate agency channel, motorcycle dealer channel (Triumph, Harley-Davidson), and OEM/embedded API distribution. The company had 700,000+ in-force contracts as of August 2025 and serves individual consumers and small businesses (commercial tenants) in Japan.
