It's not the language. It's a different investment framework.
A Japanese broker hands over a one-page maisoku and a single gross-yield figure. An international buyer needs NOI, a multi-year pro forma, and municipality-level market context. Both are right: they're reading the same property through entirely different lenses, and cross-border deals die in that gap. Tatemono IQ puts both frameworks on one page, so nothing gets lost between them.
5 Decision Layers
A single overlooked layer, such as a hidden leasehold or an aging structure, can turn a 4.8% gross yield into a real loss. Every analysis checks all five, so nothing slips past you.
How It Works
From listing to decision in three steps.
