GIR

What GIR does

GIR Co., Ltd. (株式会社GIR) is a Tokyo-based ground warranty and ground investigation services company founded in November 2000 and operating as a subsidiary of SAAF Holdings Co., Ltd. (formerly ITbook Holdings), which is listed on the Tokyo Stock Exchange Growth Market. The company's core offering is the THE LAND ground warranty system, which provides multi-year (10–30 year) coverage of up to 50 million yen per incident against differential subsidence and related ground damage for residential, commercial, and large-building properties. Coverage is delivered only when ground investigation and improvement work is performed by certified partner companies in GIR's nationwide network of 108+ certified stores at approximately 158 locations across all of Japan.

GIR's technology stack includes the GeoWeb electronic authentication system, which records GPS coordinates, timestamps, and investigation data in real time to prevent falsification, and the GOOOSE residential ground data management system, which stores ground investigation and improvement reports and integrates directly with full-automatic mechanical SWS testing equipment mandated for certified partners. Together these tools have accumulated approximately 200,000 ground investigation records across Japan, with zero reported ground-related incidents among warranted properties during the Great East Japan Earthquake. The product portfolio also includes second-opinion ground warranty evaluations, specialized coverage riders (liquefaction, retaining wall, lifeline, earthquake compensation), the THE LAND Estate pre-purchase land guarantee, THE LAND Memorial for monuments and non-building structures, housing completion guarantee (Sumair Guard), water treatment devices (ElsG, Emile), new construction and existing home inspections, and real estate trading services.

GIR monetizes through subscription-based warranty fees scaled by coverage tier (THE LAND 2000/3000/5000/BIG), professional service fees for second-opinion evaluations and inspections, hardware sales of water treatment devices, and transaction-based fees from real estate trading. Distribution is sales-led through a certified partner channel and complemented by direct online applications via the company's website, an email newsletter, and annual national partner conferences. Primary customer segments include homebuilders and construction companies, individual homeowners and property buyers, real estate developers, and commercial building operators.
