In Japanese real estate investment, you have likely wondered about these questions:
-A revenue property has been rented for years but the rent has never increased; is it priced too low? How much could it rise?
-An agent tells you "expected rent ¥200,000/month", but you feel this figure might be inflated…
-You are preparing to invest in an income property; the agent gives you a "target rent" but doesn’t know the actual rent conditions in this area — what is the market like for rentals here, what are typical key money and security deposit amounts? Or is it a market with no key money and no deposit?
Now, Urbalytics officially launches the Rent Calculator feature to help you see an area’s and a property’s real rental income potential!
1. Feature Overview | A Rent Assessment Tool That Speaks with Real Data
Urbalytics' Rent Calculator combines the platform's long‑term collected and analyzed area rental market data to help you quickly answer these key questions:
✅ Is my rent pricing reasonable?
Enter the property location, type (apartment/whole building/house), size, and current rent,
Urbalytics will calculate:
Automatic comparison with historical transaction rents for similar properties in the same area
Provide the current market average rent range and upside for rent increases
Assess the deviation rate between your current rent and the market
✅ Is the "assumed rent" overstated?
You can input the agent-provided "expected rent"; the system will:
Automatically match it to past real rental data
Provide an indicator that it is "overstated" or "reasonable"
Assess whether that yield is an "idealized" expectation
✅ Full visibility on a property's rental potential and market conditions
View all rental listings in the area by layout/key money/deposit/floor
Data fully supports judgment of the rental market's true condition and rent figures
Provide data support for rent increases, tenant replacement, or re‑negotiation
2. Use Case | Understanding the True Value of a Small Apartment
Suppose you're considering purchasing a 30㎡, 1R apartment built in 2015 near Nakano‑Sakaue station, priced at ¥44.5 million, currently vacant.
The agent tells you: for a 30㎡ unit in this area, rent is around ¥180,000/month, implying an expected annual return of 4.85%; as a relatively new building, that yield looks attractive.
You open the Urbalytics Rent Calculator and enter the details, and find:
Similar nearby listings have a real rent range of ¥136,900 ~ ¥153,000/month
The current "assumed rent" is about 20% too high
The actual gross yield is under 3.9%, not the 4.85% claimed by the agent

📌Conclusion: This is a projected return that has been overestimated; you should exercise caution when bidding or making a decision.
3. Why this feature matters
In Japan property investment, rental income is the core of cash flow.
The rent figures you hear are often just "hope", not "reality."
Urbalytics' goal is not to tell you "about how much rent might be," but to:
✅ Restore the market baseline with data,
✅ Warn you not to pay for inflated returns,
✅ Identify assets with genuine upside potential.
