The most counterintuitive finding from our analysis of 150,409 market transactions across Tokyo: Roppongi — one of the city's most internationally recognized addresses — delivers a better gross yield than Daikan-yama, Hiro-o, or virtually any newly built property in Minato Ward. At a GRM of 124.5x and a gross yield of 9.6%, a 55-year-old studio near Roppongi station outperforms a brand-new 2LDK near Daikan-yama (GRM 812.0x, yield 1.5%) by a factor of more than six. That gap is not a rounding error. It is the central tension of Tokyo real estate investment in 2026 — and understanding it is the difference between deploying capital intelligently and overpaying for a postcode.
This research note draws on 150,409 property transactions, 350,916 rent listings, and 49,939 active sales listings to map where Tokyo's residential market genuinely rewards investors — and where it quietly destroys returns.
The Tokyo GRM Baseline: What "Fair Value" Actually Looks Like
Before identifying outliers, you need to understand the market benchmark. Across all transactions analyzed, Tokyo's median GRM stands at 274.7x monthly rents, equivalent to a 22.9x annual GRM and a market median gross yield of 4.37%.
For international investors evaluating Japan real estate investment for the first time, that 4.37% figure is the honest answer to "what does Tokyo typically yield?" It is not the 7–10% sometimes cited in overseas seminars, and it is not the sub-2% reality of trophy assets in Minato or Shibuya. The median is 4.37% — useful as a floor-level filter when evaluating any specific opportunity.
The median transaction price across Tokyo sits at ¥47,000,000 for a 65 m² property, implying a price per square metre of ¥814,285. That number shifts dramatically with distance from the station: properties within a 5-minute walk trade at ¥938,462/m², while those beyond 10 minutes drop to ¥650,000/m², and properties over 20 minutes from a station fall to ¥400,000/m². Walk time to the station is, in quantitative terms, one of the most powerful single variables in Tokyo pricing.
Where the Data Points to Value: The Best GRM Stations in 2026
The stations producing the lowest GRM — and therefore the most investor-friendly entry prices relative to achievable rents — are rarely the names that appear in international property marketing materials.
Tsukishima leads the analysis with a GRM of just 77.8x monthly (yield: 15.4%) for a 1R unit averaging ¥14,473,684 in sale price and ¥186,125 per month in rent, based on 19 sales transactions and 16 rent comparables. That is not a typo. Tsukishima, on the Yurakucho and Oedo lines, is an established inner-city neighbourhood with genuine rental demand — and its pricing has not yet caught up with its income-generating capacity.
Keisei Kanamachi appears twice in the top-performer list: a 1K layout at GRM 98.9x (yield 12.1%, price ¥6,133,333) and a 1R at GRM 115.8x (yield 10.4%, price ¥6,914,286). For investors focused on Japan property yield with a limited entry budget, sub-¥7,000,000 entry prices with double-digit gross yields represent a meaningful data point — though transaction volume at these stations is thin enough (6–7 sales) to warrant caution before drawing broad conclusions.
Other notable performers include Shinjuku-gyoemmae (1R, GRM 105.3x, yield 11.4%, ¥12,000,000), Ogikubo (1R, GRM 107.3x, yield 11.2%, ¥7,620,000), Chitose-karasuyama (1K, GRM 116.1x, yield 10.3%, ¥7,700,000), and Nerima (1R, GRM 124.2x, yield 9.7%, ¥6,933,333).
A pattern emerges: the best-yielding stations in Tokyo in 2026 are predominantly served by smaller private railway lines, located in western or northern wards, and feature older building stock — typically 39 to 55 years of age.
Where Capital Goes to Underperform: The Worst GRM Stations
At the other end of the spectrum, several stations that regularly appear in Japan property investment pitches aimed at foreigners produce deeply unattractive yield metrics.
Kasuga tops the worst-performer list with a 2LDK GRM of 1,117.7x and a gross yield of just 1.1%. Daikan-yama follows at 812.0x (1.5% yield) for a near-new 2LDK built approximately 5 years ago. Hiro-o registers a GRM of 778.5x and 1.5% yield; Toritsu-daigaku comes in at 736.7x (1.6%); Tamachi at 683.3x (1.8%).
These are not obscure findings. They are the direct, quantitative consequence of buying property Japan foreigner-oriented marketing has long promoted: newly built or recently renovated units in premium wards, priced at a significant premium to their rental income capacity. A ¥1,218,182/m² price tag on a sub-10-year-old building, compared with ¥475,000/m² for a 30+ year-old equivalent, tells you precisely why age matters in Tokyo GRM analysis.
Ward-Level Pricing: The Affordability Map That Changes the Investment Case
Tokyo's 23 special wards vary enormously in median transaction price, and that variance has direct implications for Japan real estate investment strategy.
The most affordable wards by median transaction price are Adachi (足立区) at ¥33,000,000 across 3,986 transactions, Katsushika (葛飾区) at ¥34,000,000, Itabashi (板橋区) at ¥38,000,000, Edogawa (江戸川区) at ¥41,000,000, and Nerima (練馬区) at ¥43,000,000. These wards are not marginal — they have established infrastructure, reasonable commute times to central Tokyo, and active rental markets.
The most expensive wards are Minato (港区) at ¥88,000,000, Chuo (中央区) at ¥75,000,000, Shibuya (渋谷区) at ¥71,000,000, Shinagawa (品川区) at ¥66,000,000, and Meguro (目黒区) at ¥65,000,000.
The spread between Adachi and Minato — ¥33,000,000 versus ¥88,000,000 — is not accompanied by an equivalent spread in rents. The median rent across Tokyo sits at ¥130,000 per month. Rent per square metre drops from ¥4,519/m² within 5 minutes of a station to ¥3,594/m² at 10–20 minutes, but the compression between wards on the rent side is far narrower than on the price side. That asymmetry is where yield differentials are born.
Supply and Demand Dynamics: Where Renters Outnumber Available Sales
The supply/demand ratio — measured as the number of rent listings per sale transaction — reveals pockets of structural rental demand that may not yet be priced into asset values.
Setagaya leads at a ratio of 65.9x renters per sale, followed by Keisei Takasago (60.1x), Shimo-simmei (59.2x), Takinogawa-itchome (58.0x), and Kouda (54.2x). High ratios suggest that the renter pool significantly exceeds the transactional supply of comparable units — a condition that supports rental pricing stability and reduces vacancy risk.
For investors looking to buy property in Japan as a foreigner and hold for income, stations with high renter-to-sale ratios and moderate GRM values represent the more defensible combination. Stations with high ratios but also high GRM (expensive relative to rent) are less compelling — demand may be real, but the entry price already reflects it.
What the Rent Data Tells You About Layout Strategy
Across 350,916 active rent listings, the median Tokyo rent is ¥130,000 per month at a median of ¥4,149/m². But the layout-level breakdown is where strategy gets specific.
1R units have a median rent of ¥73,000/month (52,081 listings). 1K units come in at ¥92,000/month (95,364 listings — the largest single segment). 1LDK reaches ¥170,000/month across 76,307 listings, while 2LDK units average ¥225,000/month. The 1K segment's dominance in both listing volume and rent-to-price ratio explains why it appears repeatedly among the best-GRM stations in this analysis.
From a Tokyo real estate GRM perspective, the 1K and 1R segments in older buildings within walking distance of secondary rail lines consistently outperform the 2LDK and larger formats that attract the most international buyer attention. The data does not support the intuition that larger, newer, or more centrally located properties are better investments. It supports the opposite.
Key Takeaways
- Tokyo's market median gross yield is 4.37% (GRM 274.7x monthly), with extreme dispersion — from 15.4% at Tsukishima to 1.1% at Kasuga. The range matters more than the average.
- Older, smaller units near secondary stations consistently produce the strongest yields. The best-GRM stations — Tsukishima, Keisei Kanamachi, Ogikubo, Nerima — feature 1R/1K layouts averaging 39–55 years in age and entry prices between ¥6,133,333 and ¥14,473,684.
- New construction destroys yield. Properties under 10 years old trade at ¥1,218,182/m² versus ¥475,000/m² for 30+ year-old stock — a 156% premium that rental markets do not come close to compensating for.
- Ward-level price spreads are wider than rent spreads. Adachi (¥33M median) versus Minato (¥88M median) represents a 167% price gap that is not reflected in equivalent rental income divergence — which is precisely where yield differentials emerge.
- High renter-to-sale ratios at Setagaya (65.9x) and Keisei Takasago (60.1x) signal structural rental demand that may support more stable long-term income — a useful secondary filter beyond GRM alone.
