The “ RENOSY ” site displays estimated prices calculated by AI that has learned original rules from used condominium transaction data, visualization of crime rates and household attributes for each area, and nearby hospitals and schools on a map. We aim for safe and transparent real estate transactions by utilizing various data such as mapped neighborhood maps. The new visualization of the risk of ground liquefaction and flooding caused by earthquakes and torrential rains makes it possible to search for houses in consideration of disaster risks.

Since the Great East Japan Earthquake, consumers' needs for disaster risk have continued to increase, and in 2017, soil bearing capacity, susceptibility to earthquake shaking, and possibility of flooding were among the top "things to be aware of when purchasing a home (*1)". A section on sex and disasters followed.
In 2018, when the heavy rains hit western Japan, the number of landslide disasters hit a record high (*2) of approximately 3,400. Efforts are being made to prepare for prompt evacuation in the event of a disaster.

Against this background, we have developed a disaster risk map to make it easier to search for a house considering disaster risk. This makes it possible to search for homes that take into account not only the specifications of the housing but also the disaster risk in the area, and contribute to the study of optimal insurance and disaster prevention. In the future, we intend to provide more rich information such as evacuation sites and population density to support users in finding their ideal home.
