Why You Need a Second Opinion Before Buying a Condo in Japan
A question for American and global buyers in Tokyo
When your doctor proposes major surgery, what do you do?
You get a second opinion. That's standard practice. Routine. Expected.
Now ask yourself this: when a real estate agent in Tokyo tells you a ¥80 million condo is "fair market price," why do you just believe them?
It's the single biggest purchase of your life. And you're treating it with less scrutiny than a routine medical decision.
The structural problem nobody wants to name
A second opinion works in medicine because the second doctor has no financial stake in your surgery. That independence is what makes their judgment trustworthy.
Now look at real estate in Japan:
- Agents earn commission only when a sale closes
- Their income depends on you signing the contract
- Telling you "don't buy this one" costs them money
This isn't about individual agents being bad people. It's about the structure of the incentive. An agent who consistently tells clients to walk away goes out of business. The system itself punishes honest advice.
What "market price" really means (and doesn't)
When an agent says "it's priced at market," here's what you should ask yourself. Did they actually verify:
- Transaction prices (the real closing prices, not asking prices) of comparable units in the past 24 months?
- The rosenka (National Tax Agency land valuation) and koji-chika (official land price) for the underlying land?
- The depreciation curve of the building based on age, structure, and maintenance quality?
- The seller's motivation—motivated, flexible, or stubborn?
- Demographic trends and future demand in the neighborhood?
In most cases, "market price" just means "similar units are currently listed at this price." But listing prices are sellers' wishes, not facts. They tell you almost nothing about what a unit is actually worth.
What a real second opinion covers
An independent third party—one with no stake in whether you buy—should examine three things:
1. Structural price validity
Decompose the asking price into land value (via rosenka), building value (via depreciation analysis), and comparable closed transactions. Not feelings. Math.
2. Quantified hidden risks
Building age, health of the management association (kanri-kumiai), long-term repair reserves, disaster exposure, demographic decline—convert each into a numerical risk score. Make the invisible visible.
3. Negotiation leverage with evidence
Don't ask "can you lower the price?" Say: "Here are three specific reasons this price is too high." Data beats sentiment.
A second opinion doesn't replace your agent
A common misunderstanding: "If I get a second opinion, won't my agent be offended?"
Same answer as medicine. You're not firing your primary physician. You're getting a specialist to verify the diagnosis.
An agent who welcomes scrutiny is the kind of agent you want. One who bristles at it is telling you something important.
The math is obvious
A bad condo purchase in Tokyo can cost you millions of yen—sometimes tens of millions—over the following decade. Unsellable units. Ballooning repair assessments. Neighborhoods that quietly decline.
A second opinion costs less than 1% of the purchase price.
You get second opinions in medicine to protect your body. Get one in real estate to protect your assets.
RE : public is structurally free to say "don't buy this"
We are not agents. We do not earn commission on closings. Our revenue comes from the analysis itself—not from whether you sign the contract.
That's what makes us able to tell you the truth.
A republic of real estate. You already heard the agent's side. Now hear yours.
