SAME PRICE. DIFFERENT INVESTMENT.
Two listings can look identical. The analysis tells them apart.
Import both the same way, by maisoku PDF or one-click capture, and read them in one format.
Two properties at the same price and the same size are not the same investment.
Import the properties you're weighing and compare them on the numbers a listing page won't show: true cost, cash flow, building risk.

The same headline numbers, evaluated side by side
Two real Tokyo listings that a portal search returns as near-equivalents.
Two real analyses. Both listings quote a 7.40% gross yield, ¥100,000 apart on price. Listing A returns 4.41% net and a Favorable assessment; Listing B returns 3.43% net and Highly Unfavorable, on a pre-1981 seismic standard and a 45-year-old building. The gross yield is the number both listings advertise, and it is the number that does not separate them.
Comparing two Japanese listings by hand means rebuilding both first.
Every listing is formatted for whoever wrote it. Before two properties are comparable you have to normalise the layouts, convert the terms, find the official land and tax data for each address, and recompute both on the same basis. Tatemono IQ does that on import, so the comparison starts where the manual work ends.
Two listings rarely differ on the numbers a portal sorts by.
Price, size, layout, and station distance are the fields a search filters on, which is exactly why competing listings cluster on them. What separates them sits underneath: the seismic standard the building was built to, whether the repair reserve is funded, and what the cash flow does once financing and running costs are applied.
The listing tells you what they have in common. The analysis tells you what they don't.

In a data-rich market, judgment is the edge.
What matters isn't how much information you have. It's whether you can organize it, compare it, and stand behind the decision. Tatemono IQ is the foundation under that judgment.
What reduces regret isn't more information. It's better judgment.
