“Has Tama New Town failed?”

Type the name into a search engine and the answer looks settled. An aging planned town, a shrinking population, rising vacancy. I started from roughly the same image.

Then, as I worked through the transaction records one neighborhood at a time, I kept stopping. Within the same Tama, some neighborhoods sold at prices close to Tokyo’s outer wards — and the next neighborhood over did not reach half of that.

That is when the question shifted.

Not “has Tama failed” — but “which part of Tama are we talking about?”

Ep.11 covered the “average trap” in Western Tama (Hachioji, Hino, Akishima). This time we move south — to Machida, Tama City, and Inagi.

Key Takeaways

• A single “failed new town” image cannot cover this whole area.
• Even within one city, the neighborhoods people still seek out and the ones they don’t are already moving in different directions.
• Tama City’s population is projected to shrink, yet its transaction prices have held up in recent years.
• Machida is where the city’s image and its actual prices diverged the most — prices cluster around specific stations.
• Inagi is the only one of the three with projected population growth, but transactions are scarce, so neighborhood-level judgment is held back.
• Buying and renting are different stories. Purchase prices split by city, while rents near stations stay in a narrow band.

Why Write This

At first I, too, expected the whole southern belt to be uniformly weak — aging stock, shrinking population.

But going through the transactions one by one, I realized city names mattered less and less.

What people actually responded to was not the city, but the station.

This article records how my thinking changed through that process, leaning on the numbers wherever possible.

1. Three Cities, One Name, Different Faces

Machida sounds like one uniform city, but prices actually cluster around specific stations. Even within Machida, there is more than one market.

Tama carries the “failed new town” image more than any other city. But the more transactions I reviewed, the more neighborhoods appeared that the one-line verdict could not explain. The places people still seek out and the neighborhoods where prices remain subdued had already split within the same city.

Inagi I treated carefully for a different reason. Not because it is a good city, but because the transactions have not yet accumulated. In thin markets, withholding judgment is often more accurate than confidence. So the neighborhood prices appear in the table below, but please treat them as reference only.

So what happens when we put all three cities on the same scale (converted to 70 m²)?

Here are the city average, the most expensive neighborhood, and the cheapest neighborhood, side by side.

70 m² conversion. *Every Inagi neighborhood has fewer than 30 transactions (Wakabadai 23, Hirao 12) — treat the high and low as reference only.

In Machida, the average and the cheapest neighborhood almost overlap. Expensive areas are few, so places like Haramachida pull the average up.

Tama City, by contrast, shows the widest distance between its most expensive and cheapest neighborhoods. City averages look alike from the outside — step inside, and each city tells a different story.

2. Population Is Shrinking — So Why Do Prices Hold?

The city I spent the longest on in this article was Tama City. It diverged from my expectations the most.

Its population is projected to decline. By common sense, prices should follow. Yet when I checked the actual transaction flow, prices had risen steadily over the past several years.

So why have prices held up despite a shrinking population?

The answer was not “the city as a whole” but “which neighborhoods still hold demand.” Neighborhoods near stations keep attracting buyers and pull the average up, while areas full of older housing stay quietly below.

Look only at the top, or only at the bottom, and you miss the city’s real face.

3. Buying and Renting Are Different Stories

Just because purchase prices split by city does not mean rents split by the same amount.

The purchase price spread is sizable, yet rents for new one-room units near stations stay in a narrow band. So the simple yield lands in nearly the same place everywhere.

The yield reflects the fact that purchase prices and rents do not always move together. Which makes “where to live, where to buy” the more important question.

4. Frequently Asked Questions

Q. Is the “Tama New Town has failed” image accurate?

A. It is difficult to describe an entire city with a single label. Population pressure and the low prices of older housing do show up in the data — but so do neighborhoods with high prices within the same city. Only after separating the neighborhoods can we say whether it is failure, or remaining opportunity.

Q. Will prices rise again?

A. The data in this article cannot settle a long-term forecast. What is clear right now is that even within the same new town, neighborhoods are already going down different paths.

Q. Is Machida a good choice for younger residents?

A. The transit and accessibility image is real. But prices concentrate around specific stations, so it is safer not to call the whole city cheap or expensive.

Q. How should I read Inagi?

A. The city average and the population direction are usable references. But with so few transactions, neighborhood-level prices should be treated as indicative only. If a specific property interests you, check the individual transactions and the hazard maps separately.

5. Same Data, Different Readings

“The population is shrinking, so it’s risky in the long run” — one view.

Tama City’s population outlook cannot be taken lightly. But the same city also contains neighborhoods with clearly high prices. Frame the risk by city name alone, and you miss the different realities neighborhood by neighborhood.

“Prices are rising, so it has already recovered” — the other view.

The gains in some neighborhoods are real. But once you include the neighborhoods where prices remain subdued, and the places where judgment is on hold for lack of transactions, it is too early to say “it has all risen already.” Prices also move with interest rates, policy, and the broader market — one table cannot settle the conclusion.

6. Joseph’s View

Following the numbers, the question I kept returning to was one: not the name “Tama New Town,” but which station, which neighborhood.

What changed most while preparing this article was not the data but the question.

At first I was asking, “has Tama New Town failed?”

The numbers kept pointing at neighborhoods before city names. There were places where prices held even as population fell, while the neighborhoods people seek out and those they overlook were already following different paths.

I now find myself asking “Where in Tama?” before asking “Should I live in Tama?”
