Residential land in Minato-ku (港区) rose 16.6% year-on-year as of January 1, 2026, the steepest residential appreciation rate recorded among all 23 Tokyo wards in this survey cycle. That figure comes from the 地価公示 (Chika Kouji, Japan’s annual statutory land price survey conducted under the 地価公示法 / Chika Kouji-hou, Land Price Publication Act), published by the Ministry of Land, Infrastructure, Transport and Tourism on March 17, 2026. Across the 23 wards as a whole, residential land rose 9.0% and commercial land rose 13.8%, both accelerating from 2025. Of 2,503 comparable survey points across Tokyo, 2,445 recorded gains. The three wards pulling furthest ahead of that average are Minato-ku, Taitō-ku (台東区), and Shinagawa-ku (品川区), and each is moving for a distinct set of reasons.

Minato-ku: Tokyo’s Absolute Price Leader

Minato-ku has posted the highest absolute residential land values in Tokyo for several consecutive survey cycles, and the 2026 data extends that record. The 16.6% residential gain compares with 12.7% in 2025, meaning the rate of appreciation is itself accelerating. The corridors driving this are Azabu (麻布), Minami-Aoyama (南青山), Akasaka (赤坂), and Shirokanedai (白金台), where demand from high-net-worth foreign buyers, embassy-district residents, and domestic ultra-prime purchasers has compressed supply to a level that makes any new inventory immediately contested.

The Toranomon-Azabudai Hills district, which completed its main tower phases in late 2023 and continued to feed secondary-market price discovery through 2024 and 2025, remains a reference point for how large-scale mixed-use redevelopment reprices surrounding residential land. A 200-square-meter unit in the Azabudai Hills residential tower was listed at approximately ¥1.4 billion in early 2026, a figure that would have been considered outlying even three years ago. For context on sub-neighborhood pricing within Minato-ku, the Minami-Aoyama pricing and buyer profile analysis offers a detailed breakdown of how land values translate into per-unit acquisition costs.

For foreign buyers, Minato-ku also carries practical advantages that reinforce its premium. The ward contains the largest concentration of international schools in Tokyo, more than 30 foreign embassies, and direct access to Roppongi, Hiroo (広尾), and Omotesando (表参道) within a short taxi radius. These are not amenities that can be replicated elsewhere in the city at scale, and they sustain demand independent of broader market cycles.

Taitō-ku: The Fastest-Appreciating Ward Overall

Taitō-ku does not appear on most foreign buyers’ shortlists for residential acquisition, but its 2026 numbers are the most striking in the entire survey. Commercial land rose 19.1% year-on-year, up from 14.8% in 2025, the highest commercial appreciation rate among all 23 wards. Residential land followed at 14.2%, up from 10.2%, the second-highest residential rate in Tokyo. No other ward leads in both categories simultaneously.

The mechanism is tourism-driven. Asakusa (浅草), Ueno (上野), and the Akihabara (秋葉原) corridor have absorbed record inbound visitor volumes since Japan’s full reopening, and retail and hospitality operators, both domestic and foreign-owned, have been acquiring or leasing aggressively. That commercial demand is compressing cap rates on mixed-use buildings and pushing residential land values upward as a secondary effect, since 店舗併用マンション (tento-heiyou-manshon, retail-podium condominium buildings) are being repriced alongside pure hospitality assets.

For the HNW foreign buyer considering Tokyo purely as a residential address, Taitō-ku is not the natural target. The ward lacks the international-school density and diplomatic-quarter character of Minato-ku, and the residential stock skews toward smaller units. The more relevant takeaway is portfolio context: if you are considering mixed-use or hospitality-adjacent real estate in central Tokyo, Taitō-ku’s dual-category leadership in 2026 is a data point worth pricing into any acquisition model.

Shinagawa-ku: Infrastructure Premium Still Being Priced In

Shinagawa-ku (品川区) recorded a 13.9% residential land gain in 2026, up from 11.9% in 2025, placing it third among all wards on the residential measure. The consistent upward trajectory, two consecutive years of double-digit gains with an accelerating rate, points to a premium that is structural, not speculative.

The primary catalyst is the リニア中央新幹線 (Rinea Chuo Shinkansen, the Linear Central Maglev), which will terminate at Shinagawa Station and is expected to reduce travel time to Nagoya to approximately 40 minutes. Construction timelines have shifted repeatedly, but the infrastructure commitment is firm, and land markets are pricing in the terminal-city effect well ahead of opening. The secondary catalyst is the 高輪ゲートウェイシティ (Takanawa Gateway City) redevelopment, a phased mixed-use district adjacent to Takanawa Gateway Station that began opening in 2024 and continued through 2025. The project incorporates office, retail, hotel, and residential components across a site that was previously JR East rail yard land, and it is materially repricing the surrounding residential fabric.

For international assignees and executives, Shinagawa’s proximity to Haneda Airport (approximately 15 minutes by direct rail) is a practical consideration that Minato-ku cannot match at the same price point. A 120-square-meter condominium in the Takanawa (高輪) or Higashi-Shinagawa (東品川) corridor was transacting in the ¥180 million to ¥350 million range in early 2026, depending on floor, view, and building age, a spread that reflects the ongoing price discovery as new supply enters the market.

What the Tax Trajectory Means for Buyers Acquiring Now

The 地価公示 figures have direct downstream consequences for two tax bases that foreign buyers frequently underestimate. The first is 固定資産税 (kotei-shisan-zei, fixed-asset tax), which is assessed by the Tokyo Metropolitan Tax Bureau at approximately 70% of 公示価格 (kouji-kakaku, the statutory published land price). The Tokyo Metropolitan Tax Bureau confirmed in March 2026 that FY2026 land and building valuations are being released from April 2026 onward. With residential land up 9.0% to 16.6% across the leading wards, buyers should model a material step-up in their annual 固定資産税 and 都市計画税 (toshi-keikaku-zei, city planning tax) bills at the next triennial reassessment, currently scheduled for FY2027.

The second is 路線価 (rosen-ka, road frontage values used to calculate 相続税 / souzoku-zei, inheritance tax, and 贈与税 / zouyo-zei, gift tax). The 国税庁 (National Tax Agency) publishes 路線価 annually, typically in July. With 公示価格 up 8% to 16% in the three leading wards, the 令和8年分 路線価 (Reiwa 8 / 2026 edition, due July 2026) will materially increase assessed values for Minato, Taitō, and Shinagawa holdings. Foreign buyers who hold Tokyo real estate through a personal name, a Japanese holding company, or a foreign entity structure will each face different exposure to these assessed values, and the mechanics differ significantly from most Western inheritance tax frameworks. The tax and pricing overview for foreign buyers in 2026 covers the rosen-ka mechanism and its interaction with estate planning in more detail.

For buyers whose acquisition is also a visa or permanent residency consideration, note that neither 固定資産税 nor 路線価 valuations are directly linked to visa status. The 永住権 (eijuuken, Japanese permanent residency) pathway is governed by immigration law and points-based criteria, not property ownership, and no Tokyo ward confers residency rights through purchase alone.

How the Three Wards Compare: A Buyer’s Summary

The three wards occupy distinct positions in the market, and conflating them on the basis of a shared price-appreciation ranking would produce the wrong acquisition brief.

Minato-ku is the address of record for ultra-prime residential buyers. Its 16.6% residential land gain reflects genuine supply constraint in neighborhoods where the embassy corridor, international school density, and proximity to Roppongi Hills and Azabudai Hills create a demand floor that is largely insulated from domestic economic cycles. Transactions at ¥300 million and above are routine, and the upper end of the market has no effective ceiling in the current environment.

Taitō-ku leads on commercial appreciation and is the relevant ward for hospitality, retail-podium, or mixed-use investors. Its residential gains are real but the neighborhood character is different from Minato-ku or Shinagawa-ku, and foreign buyers seeking a primary residence should assess it on those terms.

Shinagawa-ku offers a credible alternative for buyers who want new-build quality, airport proximity, and a price point that, in the ¥200 million to ¥500 million range, still provides meaningful upside as the Takanawa Gateway and Linear Shinkansen premiums continue to be absorbed. The ward’s residential gains have been consistent and accelerating for two consecutive survey years, which is a more reliable signal than a single-year spike.

For a parallel analysis of Chiyoda-ku (千代田区), which does not rank in the top three on the 地価公示 residential measure but remains one of Tokyo’s most distinctive high-net-worth addresses, the Chiyoda-ku buyer profile for 2026 provides ward-specific context that the land price survey alone does not capture.
