What SIGNIFI does

SIGNIFI Inc. (シグニフィ株式会社) is a privately-held Japanese corporation founded in April 2009, headquartered in Minato-ku, Tokyo, with 128 staff as of April 2026. The company operates a hybrid business model that deliberately spans two industries: (1) B2B IT and back-office services for enterprises and care operators, and (2) hands-on nursing care and rehabilitation services operated directly by the company itself. The IT services include database technical advisory across Oracle/MySQL/PostgreSQL/SQL Server and major cloud platforms, IT project PMO support, BPO back-office outsourcing for care facilities (branded "Rifuri no Bee-Pee-Oh", ¥75,000/month), low-cost website creation for welfare operators ("Rakkuebu", from ¥3,800/month), and digital utilization training programs delivered under contract to government bodies including the Ministry of Internal Affairs and Communications.

The care and rehabilitation arm operates under the Rifuri sub-brand, comprising four physical locations in Tokyo metropolitan area (Shibamata, Harue, Kameari, Shinagawa) providing life rehabilitation day services, a specialized rehabilitation-fitness service targeting physical function maintenance and fall prevention, and a Care Plan Center that creates care plans under Japan's long-term care insurance scheme. Pricing is partly insurance-reimbursable and partly market-rate subscription. Customer segments include elderly consumers and their families (day services), care facility operators (BPO, websites, IT services), corporate clients (specialized consulting such as Lion Corporation), government entities (Katsushika Ward, national ministries), and academic institutions (Juntendo University, Shibaura Institute of Technology, international acupuncture school).

The strategic rationale is the cross-pollination between an IT-engineering core and a field-operated care business, allowing the firm to develop tools and services grounded in practical care-delivery experience rather than theoretical design. SIGNIFI has executed this via proprietary assets such as a GPS-based soccer motion analysis software co-developed with Shibaura Institute of Technology and an evidence-based rehabilitation assessment system, and via partnerships including a co-development relationship with Nankatsu SC soccer club that enables players to work at its day services while pursuing sports careers. Revenue is not publicly disclosed; the company is founder-led by CEO Takada Shiro with COO Serizawa Takeshi and CTO Hishinuma Makoto, operating without external institutional investment across its 17-year history. A planned job-matching platform called "Depa-to" is currently under preparation, targeted at the nursing and welfare workforce.
