Mycat Inc. (Headquarters: Meguro-ku, Tokyo) has newly published the "Ground x Real Estate Price Correlation Map" (https://jiban.xyz/tools/ground-value-map) within the AI Ground Improvement Cost Diagnosis "Ground Checker" (https://jiban.xyz).
### The "invisible relationship" between ground and real estate prices
According to documents from the Ministry of Land, Infrastructure, Transport and Tourism, the rate of ground improvement when building a house varies greatly depending on the region, from 20% to 70%. In areas with soft ground, ground improvement costs of hundreds of thousands to millions of yen may be incurred in addition to construction costs, but it is currently difficult to grasp this information before purchasing land.
On the other hand, it is known that there is a certain correlation between ground strength and real estate prices. Elevated areas with stable ground tend to have high land prices, while reclaimed land and lowlands may have low land prices but incur high ground improvement costs. However, there were almost no tools available to compare such information in a list format.
### Three features of the "Ground x Real Estate Price Correlation Map"
- **Just select a prefecture**: No difficult operations required. Simply select a prefecture to display the correlation between the ground strength rank of each area and the officially assessed land price data from the Ministry of Land, Infrastructure, Transport and Tourism.
- **Display ground improvement rate and estimated additional costs**: Presents an estimate of the probability that ground improvement will be required for each area and the estimated cost for the improvement work. You can grasp the "invisible costs" of land in advance.
- **Nationwide comparison is possible**: Data from 47 prefectures can be compared side-by-side, which can be used to consider relocation destinations and narrow down multiple candidate sites.
