In Tokyo real estate conversations, “the east side” carries two meanings. One is literal geography. The other is an unspoken shorthand for “the cheap side.” I used to think the same way. East equals affordable. Far from the center. Weaker for investment compared to the west. I never really questioned that assumption.

Then I actually went to Kinshicho (錦糸町) and took the train to Tokyo Station. It was far closer than I expected. Eight minutes. No transfer needed. Walking through the backstreets of Kuramae (蔵前), the border of Chiyoda-ku is right in front of you. Step out of Toyocho (東陽町) Station, and Otemachi is nine minutes away. There was a bigger gap than I anticipated between distances on a map and how the commute actually feels. That made me trace back where the “far” perception came from.

That’s when a question formed. Is this area genuinely cheap — or has its proximity to the center simply not been priced in yet? If you take the Imperial Palace (皇居) in Chiyoda-ku (千代田区) as Tokyo’s physical center, the straight-line distance to Taito-ku (台東区) Ward Office is 3 km. To Sumida-ku (墨田区) Ward Office, 5 km. To Koto-ku (江東区) Ward Office, 6–7 km. Yet mansion transaction prices here sit around 60% of Chuo-ku (中央区) levels. I wanted to understand why. So I went through actual transaction prices and rental rates, one data point at a time.¹

Arithmetic check: Taito-ku 7,762万円 ÷ Chuo-ku 1億2,680万円 = 61.2%. Sumida-ku 6,479万円 ÷ Chuo-ku 1億2,680万円 = 51.1%. Koto-ku 8,401万円 ÷ Chuo-ku 1億2,680万円 = 66.3%. Three-ward average: roughly 60%.

Data reference dates: Mansion transaction prices are based on the MLIT Real Estate Information Library, Q1–Q4 2025. Rental rates are from SUUMO for new construction within a 5-minute walk of a station and fluctuate continuously. Always check the source links directly for the latest figures.

1. Taito-ku (台東区)

Brand Positioning

Taito-ku (台東区) is Tokyo’s most double-sided ward. Hear the names Asakusa (浅草) and Ueno (上野) and your mind goes to “tradition” and “tourism” first. Not many people think of it as a real estate investment destination.

But open a map and the story shifts. Ueno Station (上野駅) connects to Tokyo Station via the JR Ueno-Tokyo Line (上野東京ライン) in roughly 8 minutes with no transfer. From Asakusa Station on the Tokyo Metro Ginza Line (銀座線), Otemachi (大手町) is about 10 minutes away. That puts you right next to the government district east of the Imperial Palace.

Taito-ku is the smallest ward by area among all 23 wards. And that small ward borders Chiyoda-ku and Bunkyo-ku (文京区) to the west. Its position places it squarely within the inner-city zone.

2026년 4월, Taito-ku officially released the “Asakusa Mirai Zuan (浅草未来図案) — Urban Development Vision.”⁴ It’s the first revision of the ward’s vision in roughly 20 years since 2007. Reflecting the dramatic shift in the foreign tourist environment following the Skytree’s opening, it outlines plans to reshape the areas around Asakusa Station and the Sumida River (隅田川) waterfront. The core goal: move away from tourism-only concentration and strengthen residential functionality.

Put the ward average of 7,762万円 alongside Chuo-ku at 1億2,680万円 or Minato-ku (港区) at 1億5,441万円, and it’s hard not to feel that the “inner-city adjacency” hasn’t been fully priced in yet.

Yushima and Nezu are the exceptions. These western neighborhoods bordering Bunkyo-ku have already crossed 1억. The price gap within the ward is wide depending on where you are. Keep that in mind.

To my eyes, Taito-ku looks more like a “city living area” than a “tourist zone.” The fact that Asakusa and Ueno come to mind first is one thing — actually living or investing there is a different question entirely.

Rental Rates

²

A rough back-of-the-envelope Cap Rate — the ratio of net rental income to property value — suggests Taito-ku has a relatively favorable rental-to-purchase-price structure compared to other wards. Of course, any real investment analysis needs to factor in vacancy rates, management fees, and tax structure as well.

2. Sumida-ku (墨田区)

Brand Positioning

If Sumida-ku (墨田区) were captured in a single photo, it would be a silhouette standing against the Tokyo Skytree (東京スカイツリー). But the Skytree is more than a tourist attraction. On 2024년 9월 21일 — Day 4,506 since opening — cumulative Skytree observatory admissions surpassed 5,000万 visitors.⁶ International visitors in FY2023 (2023-04–2024-03) reached 127万 — the first time annual international footfall exceeded 100만.⁷ That infrastructure has substantively transformed the commercial character of Sumida-ku.

But let me ask you something. Have you ever seriously considered living or investing near the Skytree?

Distance to the City Center — Comparative Data

One of the standout data points in Sumida-ku is transit access. From Kinshicho Station (錦糸町駅), the JR Sobu Rapid Line (総武快速線) gets you to Tokyo Station in roughly 8 minutes, direct. No transfer.

Put that next to Suginami-ku (杉並区), which I covered in Ep.05, and an interesting number emerges.

I found this figure quite surprising. The difference in transaction price is 38万円. The difference in travel time to Tokyo Station is roughly 13 minutes. How you interpret that gap depends on your situation and judgment. But the fact that two wards at a similar price point show this kind of access-time difference is worth noting. In my view, Sumida-ku’s locational advantage may not yet be fully reflected in its prices.

Kuramae and Morishita are already approaching Taito-ku average levels. Both neighborhoods border Taito-ku, and this is where what I’d call the “Edo-vibe hipsterification” is actively underway. Kinshicho has 126 transactions — high liquidity — the most among the sub-areas listed. That means price discovery tends to happen relatively quickly there.

Subway Line 8 Extension — The Beginning of Structural Change

2024년 11월, construction began on the Tokyo Metro Yurakucho Line (有楽町線) extension.⁸ When this line connecting Toyosu (豊洲) to Sumiyoshi (住吉) opens (targeting the mid-2030s), the north-south transit network in Sumida-ku and Koto-ku will be fundamentally transformed. Areas currently dependent on car access will gain direct connections to the city center.

Additionally, in 2025년 3월, Sumida-ku established the “Kinshicho Machizukuri Vision” (targeting 2040).⁹ It aims to comprehensively restructure commercial, business, and residential functions around Kinshicho Station, with a Grand Design formulation committee now fully operational from 2026 onward. The progress of these two projects could become a variable affecting area-specific price formation going forward.

3. Koto-ku (江東区)

A Ward of Two Faces

Koto-ku (江東区) is not a ward you can explain with a single number. The overall ward average transaction price is 8,401万円 for 70㎡.¹ But two entirely different markets coexist within that average.

The southern zone — Toyosu (豊洲) and Ariake (有明) — is already a premium market. Near Ariake Station, transaction prices hit 198.6万円/㎡; Toyosu Station comes in at 168.7万円/㎡ (343 transactions). That approaches Minato-ku’s average of 220.6万円/㎡. With the 2024 opening of Toyosu Senkyubanrai (豊洲千客万来) and the July 2025 opening of Toyosu Sail Park (豊洲セイルパーク), waterfront mixed-use development continues to pile on — pushing the development density in this zone ever higher.

The inland areas are a different story. Transaction prices in the Toyocho (東陽町), Kiba (木場), and Kameido (亀戸) corridor run below the ward average.

From Toyocho Station (東陽町駅), the Tokyo Metro Tozai Line (東西線) gets you to Otemachi (大手町) in roughly 9 minutes. Otemachi is directly east of the Imperial Palace — a 10-minute walk from Tokyo Station. The inland mansions near Toyocho are priced significantly lower than the southern Toyosu-Ariake zone.

The Toyosu-Ariake zone is significantly pulling the ward average (120.0万円/㎡) upward. Kiyosumi-Shirakawa, Morishita, and Monzen-Nakacho — the inland and semi-waterfront stations — are at or below the ward average. At 1,952 transactions, Koto-ku is among the highest in the 23 wards for liquidity; price data here is rich and price discovery is active.

Rental Rates

²

Koto-ku’s 1LDK rental rate (15.6万円) is the lowest among the three wards. The southern Toyosu-Ariake zone has already hit premium purchase prices, but that high purchase price has not fully translated into rental rates. From a Cap Rate perspective, there’s likely a divergence between the inland and southern zones — making it useful to analyze them separately rather than treating the ward as one unit.

5. Investment & Living Guide

For Residents

Taito-ku is a great ward to start in as a renter if you work in central Tokyo. The Ueno and Akihabara rail networks branch out in every direction. Tourism infrastructure is strong, which makes daily life genuinely convenient. That said, noise and congestion levels vary considerably within the ward — I’d recommend the quieter backstreets toward Kuramae and Imado (今戸) over the commercial areas near Asakusa.

Sumida-ku has surprisingly strong credentials for families. The Skytree-area improvements have created well-maintained riverside parks and walking paths. Like Koto-ku, the wide road grid makes car use practical. If you’re looking to buy in the 6,000만엔 range, the Kinshicho and Ryogoku corridor is a realistic option.

Koto-ku splits sharply based on lifestyle. The Toyosu-Ariake zone feels like an entirely different, purpose-built new city. Meanwhile the inland Kiba-Toyocho areas retain an older Tokyo character while offering excellent accessibility. The same ward delivers two completely different experiences depending on which you choose.

For Investors

Across all three wards, one thing stands out consistently: the gap between physical proximity to the center and what prices actually reflect. Whether that gap narrows — and how fast — depends on a complex of variables: interest rate environment, new supply volume, and the pace of redevelopment execution.

Let me be clear about the risks, though. Parts of these wards appear in Tokyo’s under-fault earthquake (直下地震) risk assessments at elevated caution levels. Coastal low-lying areas in particular require mandatory review of liquefaction — Ekijoka (液状化) — risk maps, where the ground can liquefy like a liquid during a seismic event. Building seismic rating and ground data should be on your checklist for any specific property.

Also note: the southern Toyosu-Ariake zone in Koto-ku already has its premium priced in. Expecting further upside there requires a different investment thesis. Kiyosumi-Shirakawa, Morishita, and Monzen-Nakacho in the inland areas are where you still find prices that look low relative to their accessibility.

When Subway Line 8 (地下鉄8号線) extension opens — targeting the mid-2030s — neighborhoods currently underserved by transit could enter a new price discovery phase. Finding pockets where the market hasn’t fully pre-priced that change is one of the strategic angles worth examining right now.

Note 1: Kuramae (蔵前) Station appears in the price tables for both Taito-ku and Sumida-ku. The station sits on the border of the two wards, and MLIT transaction data includes properties attributed to both wards in their respective counts. The difference between the Taito-ku count (127.4万円/㎡, 72 transactions) and the Sumida-ku count (110.8万円/㎡, 9 transactions) reflects the ward-boundary attribution methodology used in the data.¹
