When people hear “the north side is cheap,” certain images tend to come to mind: poor transit, run-down neighborhoods, low investment value. Usually one of those three. I used to think the same thing.

Then I actually rode the train from 西日暮里 (Nishi-Nippori) Station to Tokyo Station. It took 13 minutes. No transfers. Those 13 minutes completely changed the way I see 荒川区 (Arakawa-ku).¹

Data reference period: Mansion transaction prices are based on the Ministry of Land, Infrastructure, Transport and Tourism Real Estate Information Library, 2025 Q1–Q4. Rental rates are from SUUMO for new construction within a 5-minute walk of a station, and are subject to change. Please check the source links for the latest figures.

1. 北区 (Kita-ku)

北区 (Kita-ku) is one of the few wards in Tokyo whose very name describes a compass direction — it literally means “North Ward.” That directional name may, ironically, work against its image. In Tokyo real estate conversations, 北区 is rarely the first ward that comes up.

But open a map and the story changes. When people do think of 北区, the neighborhood that comes to mind first is usually 赤羽 (Akabane) — though the administrative and daily-life center is actually around 王子 (Oji). From a transit standpoint, 赤羽 Station carries the most weight. It’s a major interchange where the JR 京浜東北線 (Keihin-Tohoku Line), 宇都宮線 (Utsunomiya Line), 高崎線 (Takasaki Line), and 埼京線 (Saikyo Line) all converge. From 赤羽 Station to Tokyo Station on the 京浜東北線: 17 minutes, no transfers.¹

Measured from 千代田区 (Chiyoda-ku) as the center, 北区 sits roughly 7–8 km to the north in a straight line. Yet the average transaction price for a 70㎡ mansion (成約価格, actual contract price) comes in at just 46.0% of 千代田区’s level.

Arithmetic Check: 6,272万円 (北区) ÷ 1億3,630万円 (千代田区) × 100 = 46.0%

The 王子–滝野川 corridor is already approaching 100万円/㎡. The 赤羽北 and 豊島 areas sit in the low 5,000万円 range — a standout value given their proximity to central Tokyo.

The 万円/㎡ transaction price in 北区 rose from 69.0万円/㎡ in 2021 to 89.6万円/㎡ in 2025 — a 4-year CAGR (compound annual growth rate) of 6.7%.

Risks

北区 includes low-lying areas along the 荒川 (Arakawa) river and 隅田川 (Sumida River). Certain riverside neighborhoods carry elevated risks of flooding and liquefaction. When evaluating properties, always check the ward’s hazard map (ハザードマップ) for the specific location.

2. 荒川区 (Arakawa-ku)

荒川区 (Arakawa-ku) is one of the smallest wards by area in all of Tokyo’s 23 wards. Its name comes from the 荒川 river, which does in fact run along part of the ward’s boundary — giving the area a reputation as a waterside neighborhood.

But look at the transit data and that impression flips entirely.

The flagship station in 荒川区 is 西日暮里 (Nishi-Nippori) Station — a junction of the JR 山手線 (Yamanote Line) and the Tokyo Metro 千代田線 (Chiyoda Line). From here to Tokyo Station: 13 minutes, no transfers.¹ That’s the fastest commute of any ward covered in this episode.

Transaction prices sit at 44.2% of 千代田区’s level.

Arithmetic Check: 6,027万円 (荒川区) ÷ 1億3,630万円 (千代田区) × 100 = 44.2%

Personally, I came away feeling that 荒川区 hasn’t yet received the market attention it deserves. When you factor in a 13-minute direct connection to Tokyo Station, the current price level looks genuinely interesting. Once you see that number, it’s hard to just scroll past.

The 西日暮里–東日暮里 corridor is already approaching 100万円/㎡. 南千住 retains its working-class character while offering solid transaction liquidity.

荒川区’s 4-year transaction price CAGR is 5.9%, and its projected 2020→2040 population change of +5.4% is the highest among all four wards. That demand base provides meaningful support for continued price growth.⁴

Risks

The 荒川 river — the ward’s namesake — runs along the eastern boundary of 荒川区. Low-lying riverside areas carry elevated flood and liquefaction risk. While the 西日暮里–東日暮里 corridor sits at a relatively safe distance from the river, properties in the 南千住 direction should be checked against the hazard map without exception.

3. 板橋区 (Itabashi-ku)

板橋区 (Itabashi-ku) sits in the northwestern part of the 23 wards, a mix of industrial zones and residential neighborhoods with little tourist recognition. But it holds a clear distinction in this episode: it recorded the highest transaction volume of the four wards.

With 1,030 transactions in 2025, 板橋区 offers a deep pool of price data. An active market means pricing is well-validated — not a guessing game.

From 板橋 (Itabashi) Station to Tokyo Station — including a transfer — takes 23 minutes.¹ Transaction prices sit at 36.2% of 千代田区’s level — the lowest price point among the four wards.

Arithmetic Check: 4,935万円 (板橋区) ÷ 1億3,630万円 (千代田区) × 100 = 36.2%

高島平’s 44.4万円/㎡ (n=67 transactions) pulls significantly below the ward average. This sub-area includes a large number of older 団地 (danchi — public housing complexes) units with high 築年数 (building age), so direct comparisons require caution. By contrast, the 板橋 sub-area reaches 88.3万円/㎡ — close to 北区’s overall average.

板橋区’s 4-year transaction price CAGR is 5.2%.¹

4. 練馬区 (Nerima-ku)

練馬区 (Nerima-ku) is among the largest wards by population in all of Tokyo’s 23 wards. 低層住居専用地域 (low-rise residential zones — areas where high-rise construction is restricted) account for 23.3% of the ward’s total land area. That single figure tells you everything about Nerima’s character: it is, at its core, a quiet residential neighborhood.

Of all 23 wards, 練馬区 leans most strongly toward the “urban residential” archetype. Single-family homes and low-rise mansions outnumber towers; parks and green space coverage is comparatively high. It’s a ward that consistently attracts households who want a relaxed living environment without sacrificing access to Shinjuku or Ikebukuro.

I worked near 平和台 (Heiwadai) Station in 練馬区 for a period of time. The Tokyo Metro 有楽町線 (Yurakucho Line) and 副都心線 (Fukutoshin Line) both stop there, making Shinjuku and Ikebukuro straightforwardly accessible. The area was green and quiet. As a place to actually live, it had real appeal.

小竹向原 (Kotake-Mukaihara) Station — where the 有楽町線 and 副都心線 intersect — is Nerima’s transit hub. From there to Tokyo Station, including a transfer: 28 minutes. The longest of the four wards, but Shinjuku is reachable within 20 minutes.¹

Transaction prices sit at 37.6% of 千代田区’s level.

Arithmetic Check: 5,124万円 (練馬区) ÷ 1億3,630万円 (千代田区) × 100 = 37.6%

石神井町 tops out at 101.5万円/㎡ (n=37 transactions) — well above the ward average — reflecting its reputation as a premium residential enclave with excellent surroundings. 練馬区 also has the highest count of 地区計画 (district planning designations — zoning tools that tightly regulate lot coverage and permitted uses by sub-area) among these four wards, at 34 designations. That’s the mechanism keeping its streetscapes intact over time.

練馬区’s 4-year transaction price CAGR is 4.5% — the lowest of the four wards.¹

6. Investment & Living Guide

For Residents

北区 derives its strength from 赤羽 Station’s exceptional line coverage. Multiple JR lines converge here, making it a natural fit for commuters heading toward Saitama as well. The 王子–滝野川 corridor has already approached 100万円/㎡, but the 赤羽北 and 浮間 areas remain accessible.

荒川区 offers the best Tokyo Station access of the four wards. The 西日暮里–東日暮里 corridor also provides easy 山手線 transfers. That said, properties near the 荒川 river must be checked for flood risk without exception. The 南千住 area has ample transaction volume, making price verification straightforward.

板橋区 stands out as one of the most value-oriented wards within the 23. With 1,030 transactions, liquidity is strong, and the 板橋 sub-area — hovering in the 6,000万円 range — overlaps with 北区’s pricing. Access toward Shinjuku via Ikebukuro is reasonably convenient.

練馬区 is well-suited for those who want low-rise residential living. The area around 石神井町 has the feel of a premium neighborhood, with abundant parks and greenery. The 有楽町線 and 副都心線 provide transfer-free connections to Ikebukuro and Shinjuku, making central access better than first impressions might suggest.

For Investors

Looking at these four wards through an investment lens, it’s useful to split them into two groups.

北区 and 荒川区 are wards where direct transit access to Tokyo Station has not yet been fully priced in. Transaction CAGRs of 5.9–6.7% over four years are solid. 荒川区 in particular has a projected population growth of +5.4%, which provides demand-side support. Both wards carry revaluation potential — they’re ones I personally keep a close eye on.

板橋区 and 練馬区 offer a clear price advantage. Landing at 36–38% of 千代田区’s level is a favorable starting point from a rental yield perspective. The trade-off is that neither ward offers a direct line to Tokyo Station, which is a factor to weigh in any investment thesis. For owner-occupants or those prioritizing rental income, both are rational choices.

On the risk side, all four wards show flood and liquefaction exposure in varying sub-areas. When evaluating low-lying or riverside properties, always consult the Tokyo Metropolitan Government hazard map. Building seismic rating and 築年数 (building age) should also be on your inspection checklist.
