Residential land prices across Tokyo’s 23 wards rose 9.0% year-on-year in 2026, according to the 国土交通省 (Ministry of Land, Infrastructure, Transport and Tourism) 公示地価 (kōji chika, the official annual land price survey) published on 17 March 2026. That figure is the strongest gain since 1992. For foreign buyers considering luxury property Tokyo represents, the numbers are now impossible to ignore, and neither are the structural questions that accompany any acquisition: tax exposure, mortgage access, exit mechanics, and the legal continuity of who actually handles the transaction.
What the 2026 Land Price Data Actually Tells Buyers
The headline figure of +9.0% for residential land across the 23 wards conceals sharper moves at the top of the market. 港区 (Minato-ku), which contains Azabu (麻布), Hiroo (広尾), Shirokane (白金), and Roppongi (六本木), posted a residential land gain of +16.6% year-on-year, the highest of all 23 wards. The single most expensive residential land point in Japan for the ninth consecutive year is 港区赤坂 (Akasaka) 1-14-11, recorded at ¥7.11 million per square metre, up +20.5% from 2025.
Commercial land in the 23 wards rose +13.8% overall, with 18 of 23 wards exceeding +10%. The sharpest single-point gain was 渋谷区桜丘町 (Shibuya-ku Sakuragaoka-cho) 14-6, near the newly completed 渋谷サクラステージ (Shibuya Sakura Stage) development, which recorded +29.0%.
For buyers focused on per-unit pricing rather than land values, the 坪単価 (tsubo-tanka, price per tsubo, where one tsubo equals approximately 3.3 square metres) offers a more direct benchmark. In Akasaka, the average tsubo price reached ¥9.89 million in 2026, up +12.4% from ¥8.8 million in 2025. Landmark units in the same submarket, including パークコート赤坂檜町ザ タワー (Park Court Akasaka Hinokicho The Tower), exceed ¥15 million per tsubo. In Minami-Aoyama (南青山), パークコート青山 ザ タワー (Park Court Aoyama The Tower), a 37-floor building completed in 2020, currently lists units ranging from ¥350 million to ¥800 million for 80 to 200 square metres.

The Redevelopment Pipeline Driving Premium Pricing
Land scarcity in the 3A+R zone, a shorthand used by Tokyo market analysts for the Azabu, Aoyama, Akasaka, and Roppongi corridor, is structural. Height regulations and plot fragmentation make large-scale luxury supply releases rare. 三田ガーデンヒルズ (Mita Garden Hills), a 1,002-unit joint development by 三井不動産 (Mitsui Fudosan) and 三菱地所 (Mitsubishi Estate) in Mita (三田), was the largest single luxury release in a decade. Its South Hill tower listed at ¥890 million per unit.
The next significant catalyst is 赤坂二・六丁目地区開発計画 (Akasaka Entertainment City), a joint project between TBS and Mitsubishi Estate. The east tower, at 40 floors and approximately 210 metres, had its structural frame visible as of February 2026, with a completion target of 2028. A secondary redevelopment in 赤坂七丁目 (Akasaka 7-chome) is scheduled to break ground in FY2026. Rental rates in surrounding blocks are already moving in response to construction progress, and foreign capital acquisition in the submarket has accelerated, driven by the combination of yen weakness and rising international profile.
The yen factor remains material. As of early 2026, USD/JPY remains in a range that prices Tokyo prime assets approximately 30 to 40% below their 2021 peaks in dollar terms. That discount has sustained inbound foreign demand across the top end of the market, particularly from buyers based in the United States, Singapore, and the Gulf region.

Acquisition Costs and Taxes Foreign Buyers Must Budget
Japan imposes no legal restriction on foreign nationals purchasing real estate. There is no minimum purchase price, no reciprocity requirement, and no approval process specific to foreign buyers. The acquisition cost stack, however, requires precise budgeting.
| Item | Details |
|---|---|
| 不動産取得税 (fudōsan shutoku-zei, real estate acquisition tax) | applies at 3% of the assessed value for residential property and 4% for non-residential. 軽減措置 (keigen sochi, statutory reductions) apply to new builds that meet floor-area thresholds, which can meaningfully reduce the effective rate. |
| 登録免許税 (tōroku menkyo-zei, registration and license tax) | covers the cost of 登記 (touki, the transfer of legal title recorded at the Legal Affairs Bureau). Rates run from 0.15% for new residential ownership transfers to 0.4% for used residential and commercial property. |
| 手付金 (tetsuke-kin, the earnest-money deposit) | is typically 10% of the purchase price and is paid at contract signing, before the 重要事項説明 (juuyou-jikou-setsumei, the statutory pre-contract disclosure meeting) is concluded. On a ¥500 million purchase, that is ¥50 million committed before the final balance is due. |
Ongoing holding costs are equally significant. For a ¥500 million property in Minato-ku, annual 固定資産税 (kotei shisan-zei, fixed-asset tax) combined with 都市計画税 (toshi keikaku-zei, city planning tax) typically exceeds ¥2 million per year. In luxury マンション (manshon, Japanese usage: freehold condominium, not ‘mansion’ in the English sense) towers with high 管理費 (kanri-hi, monthly maintenance fees) and 修繕積立金 (shuuzen tsumitate-kin, long-term repair reserve contributions), total annual holding costs routinely reach ¥3 to ¥5 million. The Tokyo Metropolitan Tax Bureau published FY2026 assessed values under the 縦覧制度 (juran system, the public inspection period for tax assessments) from April 2026, giving buyers a formal channel to verify the tax base before committing.
Mortgage Access and the Non-Resident Financing Gap
Financing is where the gap between foreign and domestic buyers is most pronounced. Major Japanese banks, including 三菱UFJ (MUFG), 三井住友 (SMBC), and みずほ (Mizuho), generally require 永住権 (eijuuken, Japanese permanent residency) or spouse-of-Japanese status to qualify for a standard 住宅ローン (jūtaku rōn, residential mortgage). Variable-rate products for eligible borrowers remain sub-1% despite the 日本銀行 (Bank of Japan) raising its policy rate to 0.5% in January 2025, its first move since 2007. Fixed-rate 35-year フラット35 (Flat 35) products are in the 2.0 to 2.5% range as of Q1 2026.
Foreign buyers without PR typically approach financing through one of three routes: offshore private banking facilities secured against global assets, an all-cash purchase, or a domestic corporate vehicle such as a GK-TK (合同会社-匿名組合, gōdō kaisha-tokumei kumiai) structure, which is more commonly used for investment property than primary residences.
For buyers who intend to hold the property as a rental asset while non-resident, 源泉徴収 (gensen chōshū, withholding tax) applies at 20.42% flat on gross rental income, withheld by the tenant or managing agent under Article 212 of the 所得税法 (Income Tax Act). This is a gross-basis tax, meaning deductions for management fees, depreciation, or loan interest are not applied at source. A Japanese tax accountant familiar with non-resident filing is not optional at this level of investment.
Exit Mechanics: Capital Gains and Inheritance Exposure
The exit tax position for non-residents selling Japanese real estate is one of the most consequential and least-discussed aspects of Tokyo luxury property ownership. Under 譲渡所得税 (jōto shotoku-zei, capital gains tax on property disposal), non-residents are taxed at 15% national plus 5% local (20% total) for assets held more than five years, classified as 長期譲渡所得 (chōki jōto shotoku, long-term capital gains). For assets held five years or less, the combined rate rises to 39% (30% national plus 9% local), classified as 短期譲渡所得 (tanki jōto shotoku, short-term capital gains).
A critical procedural point: if the seller is a non-resident, the buyer is legally required to withhold 10.21% of the total purchase price at closing and remit it to the tax authority on the seller’s behalf, under the same Article 212 provisions. On a ¥600 million transaction, that is ¥61.26 million withheld at the moment of transfer. Buyers and sellers both need advisers who understand this mechanism before contracts are signed.
Inheritance exposure is a separate and often underestimated risk. 相続税 (sōzoku-zei, inheritance tax) in Japan applies to Japanese-situs real estate in the estate of any decedent, regardless of nationality or country of residence. Rates reach a maximum of 55%. The 2024 amendment to 相続税法 (Inheritance Tax Act) narrowed the scope of overseas assets subject to Japanese inheritance tax for non-resident foreigners, but Japanese real property remains fully within scope. Foreign buyers who hold Tokyo real estate in their personal name should obtain Japanese estate planning advice before acquisition, not after.
At Koukyuu, every engagement is handled personally by a licensed 宅建士 (takken-shi, Japan’s licensed real-estate transaction specialist) from the first consultation through due diligence, negotiation, the juuyou-jikou-setsumei disclosure meeting, and contract signing. The continuity matters precisely because the tax, legal, and structural questions described above surface at different stages of a transaction. Routing clients through unlicensed salespeople until closing day, which is standard practice at most Tokyo agencies, is not a model that holds up at the ¥300 million level. Further context on the Minami-Aoyama submarket, including specific building profiles and pricing, is available in the Minami-Aoyama: Tokyo’s refined luxury address for discerning foreign buyers in 2026 guide.
Building a Realistic Cost Model Before You Commit
Pulling the figures together into a working cost model is the practical starting point for any serious buyer. On a ¥500 million マンション unit in Minato-ku:
- Acquisition tax (不動産取得税): approximately ¥3.75 million at 3% of assessed value (assessed value is typically below transaction price for older stock; reductions apply to qualifying new builds).
- Registration tax (登録免許税): ¥750,000 at 0.15% for a new residential transfer; up to ¥2 million at 0.4% for used stock.
- Stamp duty and notary: ¥600,000 to ¥1.2 million depending on contract structure.
- Annual holding costs: ¥2 million or more in fixed-asset and city planning taxes, plus ¥1 to ¥3 million in management and repair reserve fees depending on the building.
- Exit withholding (if selling as a non-resident): 10.21% of the sale price withheld at closing.
These are not hidden costs. They are disclosed in the juuyou-jikou-setsumei and in the purchase contract. The issue is that buyers who arrive without prior context, and without an adviser who has handled dozens of transactions at this level, frequently encounter them late. The time to model them is before the shortlist is built, not after the offer is accepted.
