Residential land in Minato-ku (港区) rose 16.6% in the twelve months to January 1, 2026, the highest appreciation rate among all 23 wards in Tokyo, according to the 令和8年地価公示 (the Official Land Price Survey conducted by the Ministry of Land, Infrastructure, Transport and Tourism, published by the Tokyo Metropolitan Government on March 17, 2026). That figure nearly doubled the 23-ward average of 9.0%. For foreign buyers weighing where to allocate capital in the world’s third-largest metropolitan economy, the three wards that consistently record the highest absolute land values per square metre are Minato-ku, Chiyoda-ku (千代田区), and Shibuya-ku (渋谷区). What separates them is worth understanding in detail.

Minato-ku: Tokyo’s Highest Residential Appreciation in 2026

Minato-ku is the single ward most foreign high-net-worth buyers encounter first, and the 2026 data confirms why it retains that position. The ward contains Azabu (麻布), Hiroo (広尾), Shirokane (白金), Akasaka (赤坂), Roppongi (六本木), and Toranomon (虎ノ門), the densest concentration of ultra-luxury residential stock in Japan.

At the top standard points in Azabu and Hiroo, residential 地価公示 (chika-kouji, the official assessed land price per square metre under the Land Price Publication Act) benchmarks regularly fall between ¥3,000,000 and ¥5,000,000 per square metre. To translate that into a transaction: a 200-square-metre residential lot in central Azabu carries a land component assessed at ¥600 million to ¥1 billion before any structure is factored in. The single highest-priced residential standard point in Akasaka was recorded at ¥7,110,000 per square metre in the 2026 survey, the highest land price point in Japan for that category.

The structural driver is redevelopment. Azabudai Hills (麻布台ヒルズ), completed in late 2023 and fully operational through 2024, repriced surrounding parcels materially. The effect was still feeding through to assessed values in the January 2026 survey. Toranomon’s ongoing office and mixed-use corridor continues to compress the boundary between commercial and premium residential pricing in the ward’s northern half.

For foreign buyers specifically, Hiroo merits attention beyond the headline numbers. The neighbourhood has the highest concentration of foreign residents in Tokyo, sustained by proximity to the German School, the French Lycée, and a cluster of embassies. That structural foreign demand creates a more liquid secondary market for premium マンション (manshon, Japanese usage meaning freehold condominium, distinct from the English word ‘mansion’) than exists in most other Tokyo neighbourhoods at comparable price points.

Minato-ku’s +16.6% residential appreciation outpaced the 23-ward average of +9.0% by a factor of nearly two. The ward’s commercial land also appreciated strongly, consistent with the broader 区部 (ku-bu, the 23-ward central Tokyo area) commercial average of +13.8% recorded in the same survey.

Chiyoda-ku: Scarcity, Bancho, and Japan’s Most Expensive Commercial Corridor

Chiyoda-ku occupies a structurally different position. Its commercial land, anchored by Marunouchi (丸の内) and Otemachi (大手町), consistently records the highest per-square-metre assessed prices in Japan. Standard points in the Otemachi corridor have historically placed in the national top three for commercial land values, and the 2026 survey maintains that ranking.

The residential picture is defined by scarcity. A significant portion of Chiyoda-ku is occupied by the Imperial Palace grounds, government ministries, and corporate headquarters, leaving a limited residential footprint. The neighbourhoods that do exist, primarily Bancho (番町) and Kojimachi (麹町), function as Tokyo’s equivalent of London’s Belgravia: low-rise, quiet, close to the Imperial Palace moat, and preferred by ambassadors, senior executives, and established Japanese families. Supply is structurally near zero. Transactions at this level are almost entirely off-market.

For a fuller picture of what Chiyoda-ku offers foreign buyers at the top of the market, the Chiyoda-ku residential buyer’s guide covers the ward’s sub-neighbourhoods, ownership structures, and practical considerations for non-residents in detail.

Foreign buyers should note that Chiyoda-ku’s residential market is not a place where listed properties sit for months. The combination of limited supply, institutional-grade tenant demand, and proximity to the political and financial centre of Japan means that the few properties that do change hands move quickly and rarely through conventional channels.

Shibuya-ku: Shoto, Hiroo, and the Prestige of Pure Residential Addresses

Shibuya-ku rounds out the top three on both absolute per-square-metre values and the quality of its residential sub-neighbourhoods. The ward covers Shoto (松濤), Hiroo (which straddles the Minato-Shibuya boundary), Daikanyama (代官山), and Ebisu (恵比寿).

Shoto is arguably Tokyo’s most prestigious purely residential address. The streets are zelkova-lined, the lots are large by any Tokyo standard, crime is negligible, and the neighbourhood has been preferred by old-money Japanese families and foreign diplomats for decades. It does not have the commercial energy of Roppongi or the expat infrastructure of Hiroo, which is precisely the point. Buyers who want quiet, discretion, and a residential environment with no through-traffic pay accordingly.

On the commercial side, the Shibuya Station mega-redevelopment, including Shibuya Scramble Square (渋谷スクランブルスクエア) Phase II, remains under construction through 2027. Land values in the immediate station catchment have responded to that pipeline, and the effect is beginning to spill into adjacent residential streets in Daikanyama and upper Ebisu.

Shibuya-ku’s residential appreciation tracks broadly with the 23-ward average of +9.0%, but its absolute per-square-metre values at the top standard points remain among the highest in Tokyo, placing the ward consistently in the national top three to four for residential land pricing. The Minami-Aoyama residential market overview provides a useful parallel read for buyers considering the Aoyama (青山) addresses that sit on the Shibuya-Minato boundary.

What the 2026 Land Price Data Actually Means for Buyers

The 地価公示 figures are assessed values at designated 標準地 (hyoujunchi, standard land parcels), not transaction prices. Market transactions in Azabu, Bancho, and Shoto routinely clear at premiums to assessed values, particularly for large lots and off-market deals. The survey data is most useful as a directional indicator and a basis for tax calculations rather than as a direct guide to what a seller will accept.

Two tax figures matter immediately for foreign buyers. 固定資産税 (kotei-shisan-zei, fixed asset tax) is levied at 1.4% of the assessed tax base, which is typically 60 to 70% of market value. 都市計画税 (toshi-keikaku-zei, city planning tax) adds 0.3% in Tokyo’s 23 wards. The combined effective rate is approximately 1.0 to 1.2% of market value annually. For residential land up to 200 square metres, the 小規模住宅用地 (shokibo-jutaku-yoichi, small residential land) reduction cuts the fixed asset tax base to one-sixth of assessed value and the city planning tax base to one-third, a material saving for buyers of detached houses in Minato-ku or Shibuya-ku.

For foreign owners considering an eventual exit, a rule change effective April 1, 2026 requires non-resident sellers to register for 消費税 (shohi-zei, consumption tax) and remit 10% directly to the 国税庁 (National Tax Agency) when the building portion of a sale exceeds ¥10 million. This replaces the previous buyer-withholding mechanism and requires advance preparation. Engaging a Japanese tax advisor before listing is not optional at this price level.

The broader macro context supports continued appreciation. The Tokyo Metropolitan Government’s March 2026 commentary cited gradual economic recovery, a sharp increase in inbound tourism, and large-scale redevelopment progress as the primary demand drivers. Critically, the half-year data covering July 2025 to January 2026 showed acceleration rather than deceleration: the second half of 2025 outpaced the first half across all land categories in the 23 wards. The official 2026 land price release from the Tokyo Metropolitan Government provides the full ward-by-ward breakdown for buyers who want to verify figures independently.

Practical Considerations for Foreign Buyers at This Level

Ownership of Tokyo real estate carries no nationality restriction. Foreign nationals, whether resident or non-resident, may purchase freehold property in Japan without government approval. Financing is a different matter: most Japanese lenders require 永住権 (eijuuken, Japanese permanent residency) or a domestic income stream to extend mortgage credit to foreign nationals. Buyers without PR status typically transact in cash or arrange financing through private banking relationships outside Japan.

The 重要事項説明 (juuyou-jikou-setsumei, the statutory pre-contract disclosure meeting) is a legal requirement before any Japanese real estate contract is signed. It must be conducted by a licensed 宅建士 (takken-shi, Japan’s licensed real-estate transaction specialist). The document covers title status, zoning, building coverage ratios, encumbrances, and any material defects known to the seller. For foreign buyers unfamiliar with Japanese property law, this meeting is the single most important point of due diligence in the transaction, and the quality of the 宅建士 conducting it determines how much risk the buyer actually understands before committing.

At Koukyuu, a licensed 宅建士 personally handles every stage of the engagement, from the initial consultation through viewings, negotiation, due diligence, the 重要事項説明, and the 登記 (touki, the transfer of legal title recorded at the Legal Affairs Bureau). Most Tokyo agencies route clients through unlicensed salespeople until closing day. For transactions in Bancho, Azabu, or Shoto at the ¥300 million-and-above level, that distinction is not a minor procedural point. For a comprehensive overview of what foreign buyers face at the luxury end of the Tokyo market, the 2026 luxury property tax and pricing guide covers acquisition costs, holding taxes, and exit mechanics in full.

Koukyuu is a private buyer’s advisory for distinguished Tokyo residences in Nishi-Azabu (西麻布), Shirokane, Roppongi Hills, and Chiyoda-ku, focused exclusively on transactions of ¥300 million and above, with a licensed 宅建士 personally handling every stage from first consultation to signing.
