KUFU, Inc. is the founding name of SmartHR, Inc., the Japanese cloud HR platform, and remains the company's GitHub organization identity. SmartHR is a system of record for employee data across Japanese back-office HR — hiring and onboarding, social insurance and labour paperwork, family and dependent records, organizational structure, payslips, and withholding tax slips. The SmartHR API is a tenant-scoped REST API on a per-customer subdomain, described by a live Swagger 2.0 document covering 60 paths and 120 operations, and is offered free to existing SmartHR customers. It ships a webhook event surface, an application-gated sandbox on a separate domain, and an open-source React component library, but no official client SDK.
