About JikoDB
Is that property really safe?
JikoDB is a service that lets you check stigmatized properties, disaster risks, and public safety information all at once simply by entering an address. When considering a move or property purchase, you can verify risks that are easily overlooked in one place.
What is JikoDB?
JikoDB is an "area risk check tool." It is more than just a stigmatized property database -- it consolidates all the information you should know before living in an area, in one place.
Whether renting or buying, it is important to confirm "Is this area really safe?" before deciding on a property. JikoDB is designed to complete that check in seconds.

3 Reasons to Use JikoDB
1. Everything you need from a single address
Previously, you had to check stigmatized properties, disaster risks, and safety information on separate websites. JikoDB displays all risk information on one screen from a single address input. No more missing important checks.
2. Clear listing basis
All stigmatized property information is displayed by listing basis: "Real Estate Listing" or "Information Provided." Real estate listings with disclosure-required wording are distinguished from information provided to the database.
3. Know what to ask your real estate agent
JikoDB's information serves as question prompts you can use when negotiating with real estate companies. You'll be able to ask specific questions like "There was a fire report near this property -- is it related?" or "Is this subject to a disclosure obligation?"
