basic information
■Visualization of Survey Results / Ground Investigation By adopting the "weight-based loading method," which is a benefit of manual surveys, we achieve a survey that is highly consistent with JIS standards. With the "Ground Pro Series," which balances improved survey accuracy and operability, we provide safe and secure ground investigations. ■Visualization of Analysis Standards / Advanced Analysis The analysis process complies with relevant laws and regulations, including the Ministry of Land, Infrastructure, Transport and Tourism's notifications. Through advanced analysis based on guidelines set by the Architectural Institute of Japan and design and construction standards for defect liability insurance, we reduce excessive ground improvement work. ■Visualization of Improvement Work / Design Review Compensation We conduct free pre-review of designs and post-review of construction reports. Ground Network, which does not undertake improvement work, verifies safety and appropriateness from a third-party perspective. ■Visualization of Compensation Details / Ground Long-Life Compensation System For properties applied for "Ground Safe Housing," we issue a "Ground Quality Certificate." In the unlikely event of differential settlement, we will compensate for building damages up to 50 million yen for 20 years as initial compensation. By undergoing regular inspections, compensation can be renewed every 20 years.

Applications/Examples of results
Annual survey record of 50,000 buildings! The ratio of cases determined as "unnecessary" for improvement work based on analysis is 76% (as of September 2017, our company's assessment record) *when using "Ground Pro." For properties applied for "Ground Assurance Housing," a "Ground Quality Certificate" will be issued. In the unlikely event of differential settlement, we will compensate for building damages up to 50 million yen for 20 years as initial compensation. By undergoing regular inspections, compensation can be renewed every 20 years. ● Extended compensation system that covers lifelong risks In addition to the supplementary period starting from the assessment date and the initial compensation for up to 20 years from the delivery date, compensation can be renewed throughout life through regular inspections and updates (for a fee) every 20 years. ● Permanent confirmation of the latest ground risks by professionals Regular inspections every 20 years will be conducted by ground inspectors with architectural qualifications. After the inspection, a "Ground Screening Report" will be provided, which is based on the latest topography, land history, and neighboring data. By regularly reviewing the ground risks that change over time, optimal measures can be taken.

Company information
In earthquake-prone Japan, the occurrence of earthquakes cannot be avoided. However, when building a house, one can "choose the foundation." The difference between a house that has sunk due to liquefaction from an earthquake and a house that has sustained no damage just across the road lies in the foundation. By investigating the land's foundation, selecting land with as strong a foundation as possible, and conducting appropriate improvement work if the foundation is weak, the damage from earthquakes can be minimized. What is truly frightening is not the earthquake itself, but the foundation. In other words, if one can correctly understand the foundation, the damage from earthquakes can be kept to a minimum. Until now, it cannot be said that risk information about land has been sufficiently disclosed when consumers purchase real estate. However, in order for everyone to obtain a safe home, an environment where accurate information about the foundation can be easily accessed, even by non-experts, is necessary.
