In Ep.09, I looked at the western premium belt centered on Musashino, Mitaka, and Chofu. This episode moves a little further west along the Chuo Line to cover Kokubunji, Kunitachi, Fuchu, and Tachikawa — four cities that make up what I call the Tama Education & Culture Belt.

This area is often described as “affordable suburbs beyond the 23 wards.” Going through the transaction data city by city, I found it difficult to treat all four as one market. Even within a single city, different neighborhoods showed very different price maps — shaped by rail access, redevelopment activity, and local character.

First, the bottom line

• The four Tama cities are not a single “cheap suburb” — it is more accurate to see them as four distinct markets with different rail lines, redevelopment trajectories, and land uses.
• Even within the same city, prices per ㎡ diverge by more than 3x depending on the neighborhood (e.g., Tachikawa: Akebono-cho 83.4万 vs. Ichiban-cho 23.0万).
• Despite wide purchase-price spreads, new-build 1R rents near stations generally converge at 8.0–9.4万円/月.
• Population and income are background context. What better explained price differences in this dataset was station access, rail line, and redevelopment activity.
• All four cities carry flood and liquefaction risk flags. When evaluating a specific neighborhood, cross-reference the relevant hazard maps separately.

Why this article

I started by thinking of the Tama area as a single zone — “somewhere more affordable than the 23 wards,” a value-oriented corridor. Kunitachi as a university town, Fuchu with its government offices and racecourse, Tachikawa with its regional hub feel — all often grouped under one “value” label.

Going through neighborhood-level transaction prices changed that. Price gaps kept appearing that city names alone could not explain, and which neighborhood, which rail line, whether redevelopment is underway turned out to matter more than the city name.

That is why this piece focuses less on city averages and more on neighborhood-level price structure.

Starting hypothesis vs. what the data changed

I initially expected the four cities to sit at roughly similar levels of suburban premium. Looking at the data, my impressions shifted as follows.

Table of contents

1. Four cities, four markets

The table below is not about “which city is cheapest” — it is about “where within each city carries a premium.”

Kokubunji City — Western Rail Hub

Kokubunji Station records approximately 30.6万 daily passengers, making it the clearest hub among the four cities. City-wide ㎡ price rose from 58.7万円 in 2021 to 82.2万円 in 2025 (4-year CAGR 8.8%). 70㎡ ≈ 5,754万円 (approximately 42.2% of Chiyoda Ward [Ep.01] benchmark).

Key observation: Honcho’s 126.5万 is the highest cho-me figure across all four cities, linked to the Kokubunji Station North Exit redevelopment and the JR Chuo Line/Seibu Line interchange. With n=37, I treat this as directional rather than definitive, using MLIT cho-me transaction data as the basis rather than walk-time estimates.

Kunitachi City — University Town, Wide Neighborhood Variation

Home to Hitotsubashi University and Tokyo Gakugei University — an academic and residential city. Kunitachi Station records approximately 9.4万 daily passengers — smaller than the hubs of Kokubunji and Tachikawa. ㎡ price: 53.8万 → 64.2万 (CAGR 4.5%), 70㎡ ≈ 4,494万円 (approximately 33.0% of Chiyoda).

Where the hypothesis broke down: Per-capita income ranks #1 among the four cities (191.9万), yet the highest-price neighborhood is lower than Kokubunji Honcho. The framing of “university town = uniform premium” does not hold — reading Higashi/Naka vs. Aoyagi/Yagawa as separate zones is more accurate. Station traffic and large-scale redevelopment catalysts are comparatively weak here.

Fuchu City — Administrative, Entertainment, and Residential

Anchored by Tokyo Racecourse and Fuchu Station — an administrative and entertainment axis. Bubaigawara Station records approximately 15.7万 daily passengers; the city has 14 stations. ㎡ price: 48.9万 → 60.3万 (CAGR 5.4%), 70㎡ ≈ 4,221万円 (approximately 31.0% of Chiyoda).

Where interpretation diverges: The contrast between Miyanishi-cho and Shiraito-dai is sharp. Transaction volume (370 cases) is the highest among the four cities, indicating good market liquidity. The data reads as a dual structure: administrative/entertainment neighborhood premiums alongside peripheral low-price zones, coexisting within one city.

Tachikawa City — What the City Average Hides

A city with a strong administrative and commercial sub-center image. Tachikawa Station records approximately 30.1万 daily passengers; combined city-station traffic approximately 52.6万/日. ㎡ price: 42.1万 → 50.8万 (CAGR 4.8%), 70㎡ ≈ 3,556万円 — lowest city average among the four (approximately 26.1% of Chiyoda).

What changed my view: Looking at only the city average suggests “Tama’s lowest-price market,” but Akebono-cho is in the 80万 range. Cross-referencing public redevelopment data (Tachikawa Takurosu, etc.) with the Akebono-cho vs. Ichiban-cho contrast, the split emerges: Akebono-cho as a station/redevelopment/infrastructure axis, Ichiban-cho as a different residential character — Seibu Line, low-rise. Ichiban-cho n=19 — treat as directional reference only.

2. Two living zones within Tachikawa

Let me pause here. The 3.6x gap within Tachikawa was the part of this analysis I spent the most time on.

Grouping everything under “Tachikawa” hides the gap in the table above. Akebono-cho and Ichiban-cho differ not just in price but in the character of the living zone itself.

Akebono-cho — JR Tachikawa and Tama Monorail Tachikawa-Kita interchange, north-exit redevelopment (Tachikawa Takurosu, completed 2016), station-adjacent commercial and new-build condo axis. Public land price and listing data show station-proximity premiums here repeatedly.

Ichiban-cho — Stronger affinity with the Seibu Tachikawa zone, with a large share of Category 1 Low-Rise Exclusive Residential zoning. A transaction ㎡ price in the 20万 range reads less as “Tachikawa being cheap” and more as a signal of a different rail catchment and residential type.

I initially expected redevelopment to be the dominant driver pulling Akebono-cho prices up. Reviewing the data alongside public records, the Akebono-cho 83.4万 vs. Ichiban-cho 23.0万 gap aligned with that expectation — the north-exit redevelopment and hub station axis was indeed the Akebono-cho side.

3. Purchase prices and rents move on different logics

It is easy to assume that expensive neighborhoods command higher rents too. The data did not always bear that out. What struck me more was that the purchase-price map and the rent map moved independently.

The table below places city-average ㎡ prices alongside SUUMO new-build 1R rents (1–5 min walk from station).

*70㎡, city-avg ㎡ price, pre-tax, excluding management fees and vacancy. Structural comparison only — not investment advice.

At the neighborhood level: A low-purchase-price cho-me like Tachikawa Ichiban-cho (23.0万/㎡) could show a gross yield of 4–6% assuming the same city-level 1R rent (8.0万円/月) — though actual Ichiban-cho 1R rents may be lower. Kokubunji Honcho (126.5万) and Tachikawa Akebono-cho (83.4万) carry large purchase premiums, compressing gross yield to approximately ~1.3–1.6%.

Within the same belt, purchase prices and rents moved on different logics. Whether for owner-occupancy or investment, reading location → rail line → redevelopment → rent in that order proved more useful in this dataset.

4. Background data worth keeping in mind

Population and income are worth referencing. That said, in this analysis their power to explain price differences was relatively limited. The tables below are context for understanding how the Tama belt compares to the 23 wards and municipal averages — not a guide to which city to buy in.

Population projections (2020 → 2040)

All four cities show gradual rather than sharp change. Only Tachikawa projects a modest decline.

Per-capita income (FY2024 · 万円/person)

All four cities sit below the municipal average (~208万) and further below the 23-ward average (~287万). City names alone do not sort purchase-price rankings. What actually mattered more in this dataset was station access, rail line, and redevelopment activity.

5. Four-city summary comparison

Here is a summary of what I covered above.

One thing that stood out: Kokubunji had the highest CAGR (8.8%), while Kunitachi had the highest income (191.9万). Income and purchase prices did not always move in the same direction.

Positioning within the series:

6. The same data, read differently

There are other ways to read this data.

“Tama is discounted relative to the 23 wards — city averages are enough.”

In periods of falling interest rates or broad market rallies, city-level averages can capture the big picture. In this dataset, however, city averages hid neighborhood premiums like Honcho, Akebono-cho, and Miyanishi-cho, and erased the 3.6x gap within Tachikawa.

“High-income Kunitachi is undervalued and due to outperform.”

It is easy to assume the highest-income city will also have the highest prices. The 2021–25 CAGR for Kunitachi (4.5%) was lower than Kokubunji (8.8%), and income rank #1 and price-rank #1 neighborhood were not the same city. Income-based city selection is a weak frame in this dataset.

7. Who this may / may not help

This may be useful if you:

• Want to evaluate location by neighborhood, rail line, and redevelopment rather than city name
• Prefer to read purchase prices and rent/yield separately
• Are considering western hub or Tama zone options outside the 23-ward budget
• Want to understand the differences between four distinct markets before committing to one

This may not be a fit if you:

• Plan to conclude “Tama = cheap” based on the city name alone
• Are mapping income rank = price rank directly
• Are assessing without checking hazard maps (flood, liquefaction)
• Are targeting city-level beta for short-term price appreciation only

8. Joseph’s View

A data-reviewed assessment. No field anecdotes or fictional experience included.

Reflecting on this piece

The question I stayed with longest while preparing this was: “Is Tama really one market?” As I compared transaction records, my vague assumption that the four cities would be roughly similar started to break. Kokubunji Honcho 126.5万 and the 3.6x gap within Tachikawa do not fit the “affordable suburb” framing. The more I compared the data, the more my original assumption began to change — and in the end, neighborhood and living zone explained more than city name.

What I will keep reading this way

Treating the four markets separately, watching the dual structure within Tachikawa, and reading the purchase-price map and rent map independently. Purchase map ≠ rent map.

What I am still not certain about

Neighborhoods with fewer than 30 transactions (Aoyagi: 7 cases, Ichiban-cho: 19 cases) — I treat these as directional signals only. If redevelopment or rail configurations change, the market will shift with them.

Recommended verification sequence for readers

If there is a neighborhood you are considering:

1. MLIT transaction price distribution for that neighborhood (cho-me)
2. Rail lines and living zone character
3. Public redevelopment documents
4. Hazard maps
5. Actual rent listings (SUUMO etc. — gross yield is structural comparison only)

In one line

The Tama Education & Culture Belt is not a single cheap area but four markets — and even within the same belt, location, rail line, and redevelopment diverge. Purchase prices spread wide while station-adjacent new-build rents cluster in the 8–10万円 range. In this dataset, choosing the location first — then examining rent and yield — proved more useful.
