No credit card requiredWhy teams trust the output
Evidence your team can defend.
Every recommendation is traceable to sources, refresh timing, and method so decisions are easier to trust internally and with clients.
Official source provenance
Each layer is tied to official publishers such as MLIT and local government open data portals.
Public-release refresh cycle
Datasets are refreshed in line with public release schedules to minimize stale information.
Verification workflow
We standardize and validate records before publication so map layers stay consistent across regions.
Methodology transparency
We clearly separate official records from platform-derived signals so confidence is easier to assess.
Sample output
From property data to a decision summary your team can act on.
This sample shows how value range, constraints, and market signals become a practical proceed, hold, or reject call.
Fast value-range screening
Start with a directional value range anchored to official prices, comparable signals, and live listings.
Constraint checks in one place
Review hazard, zoning, access, and school context together so major blockers appear early.
Recommendation with source trail
Deliver a decision summary that teammates and clients can review without guessing where the conclusion came from.

Why the recommendation holds up
The output is only useful if the underlying evidence is traceable. These are the core inputs behind each property decision.
Check value, constraints, safety, and market reality before you spend more time on the site.
Official and authoritative sources, refreshed on public release cycles.
Boundaries
Which lot are we actually deciding on?
Lot boundaries and official lot numbers (地番) for all of Japan—over 102 million searchable lots.
Everything else depends on knowing which piece of land is which. Boundaries connect zoning, hazards, and school districts to the right property.
Risk
Will risk change the call?
Official maps showing flood, landslide, and liquefaction risk for an area.
Risk affects insurance costs, resale value, and peace of mind. High-risk areas can limit financing options and reduce buyer interest.
Regulation
What can this site actually become?
Government designations that define what you can build—residential, commercial, mixed use, height limits.
Zoning rules decide what can be built—a house, a shop, or something taller. This directly affects property value and how the land can be used.
Education
Will location context strengthen demand?
Which public elementary and junior high school a property belongs to.
Families care a lot about which school their kids will attend. Good school districts typically drive higher demand and stronger resale value.
Value
Is the price grounded in reality?
Official published land prices used as a reference for market value and taxes.
Provides market context for evaluating prices, making offers, and understanding tax implications. A reality check against local market values.

Market

Still spending half a day to evaluate one property?
Most teams are still stitching hazard maps, zoning pages, price tables, and listing portals by hand. That slows decisions and increases the chance of missed risk.
Scattered process
- Open multiple portals for one property
- Switch between hazard and zoning sites
- Rebuild context from school and market sources
- Copy findings into notes or spreadsheets
- Lose rationale during handoff
- Re-check the same questions in every review
Decision workflow
- Review lot, risk, constraints, and market context in one place
- Capture decision rationale with attached evidence
- Share one source of truth across the team
- Move from research to next step faster
