Fact-checked against current Japanese real-estate law, tax rules, and market data by a nationally licensed specialist who oversees luxury transactions across Minato, Shibuya, and Chiyoda. In Japan, a Takkenshi is legally required to sign off on every property transaction, and about 15% of candidates pass the exam each year.
A 141.75㎡ residence on the 27th floor of Roppongi Hills Residence B (六本木ヒルズレジデンスB棟) is currently listed at ¥1.22 billion, or roughly ¥8.6 million per square metre. That single data point captures where Tokyo’s super-prime residential market sits in April 2026: prices that rival central London and Manhattan, a buyer pool that is increasingly international, and a regulatory environment that is shifting in ways most foreign buyers have not yet registered.
This article covers the four things a high-net-worth foreign buyer needs to understand before engaging with luxury homes in Tokyo, Japan: where the market is priced today, what ownership actually costs beyond the purchase price, how Japanese law treats foreign purchasers, and the inheritance-tax rule change taking effect on January 1, 2027 that has quietly reshaped the investment calculus for the entire asset class.
Where the Market Is Priced in 2026
Tokyo’s luxury residential market has three broadly recognisable tiers, each with distinct product types and buyer profiles.
The entry tier for what the market now calls “ultra-luxury” runs from roughly ¥300 million to ¥500 million. At this level, a buyer is typically purchasing a マンション (manshon, Japanese usage for a freehold condominium, distinct from the English word “mansion”) in a premium Minato-ku (港区) or Shibuya-ku (渋谷区) tower, with floor areas in the 80–120㎡ range. Park Court Aoyama The Tower (パークコート青山ザタワー), a 37-floor, 320-unit tower completed in 2020 in Minato-ku, illustrates the tier: current listings run from ¥350 million to ¥800 million for units between 80㎡ and 200㎡.
The mid tier, from ¥500 million to roughly ¥1.5 billion, includes addresses like The Park House Gran Minami-Aoyama Takagi-cho (ザ・パークハウスグラン南青山高樹町), a five-floor, 50-unit low-rise completed in 2019 in Minato-ku, where listings range from ¥500 million to ¥1.2 billion for units between 120㎡ and 250㎡. The Roppongi Hills Residence B listing cited above sits in this tier.
Above ¥2 billion, the market shifts to freestanding estates and trophy land. In Kagurazaka (神楽坂), a 400-tsubo (approximately 1,322㎡) Japanese-style estate commands land values alone of ¥2 billion or more, based on prevailing land prices of ¥5 million per tsubo in that district. In Azabu (麻布), Hiroo (広尾), and Shirokane (白金), comparable freestanding properties regularly transact between ¥2 billion and ¥10 billion.

The True Cost of Ownership: Beyond the Purchase Price
Foreign buyers accustomed to markets like Singapore, Hong Kong, or the United States sometimes underestimate Tokyo’s annual carrying costs. Three categories matter.
Property Taxes
Every Tokyo property owner pays 固定資産税 (koteishisanzei, fixed-asset tax) at 1.4% of assessed value annually, plus 都市計画税 (toshikeikakuzei, city planning tax) at 0.3%, applicable across all central Tokyo wards. The assessed value, known as 固定資産税評価額 (koteishisanzei hyoukagaku), is typically 50–70% of market price for land and approximately 60% of construction cost for buildings, declining with depreciation.
In practical terms: on a ¥1 billion property, expect combined property taxes of ¥7 million to ¥12 million per year. On a ¥500 million Minami-Aoyama (南青山) unit, the annual 固定資産税 alone is estimated at ¥2 million or above.
Management and Repair Reserve Fees
Luxury tower マンション carry monthly 管理費 (kanrihi, building management fee) and 修繕積立金 (shuuzen tsumitatekin, long-term repair reserve fund). At Roppongi Hills Residence B, the combined monthly charge is ¥178,363, or approximately ¥2.14 million per year. Across the broader luxury tower segment, the range runs from ¥80,000 to ¥200,000 per month, meaning ¥960,000 to ¥2.4 million annually before any special assessments.
Acquisition Taxes
At purchase, two taxes apply. 不動産取得税 (fudousan shutokuzei, Real Estate Acquisition Tax) is levied at 3% of assessed value for residential property. 登録免許税 (touroku menkyozei, Registration License Tax) applies at a reduced rate of 0.3% of assessed value for residential ownership transfers. Neither is enormous relative to the asset price, but both are due within months of closing and should be budgeted in advance.
Foreign Buyers: Legal Status and Access
Japan imposes no restrictions on foreign nationals purchasing real estate. There is no reciprocity requirement, no minimum residency period, and no cap on foreign ownership in any residential zone. A non-resident buyer from the United States, United Kingdom, Australia, or any other country may purchase a ¥1 billion Azabu estate on the same legal footing as a Japanese citizen.
For a thorough walkthrough of the purchase process from a foreign buyer’s perspective, including mortgage access, visa considerations, and the statutory 重要事項説明 (juuyou-jikou-setsumei, the pre-contract disclosure meeting required by law before any real estate transaction in Japan), the houses for sale in Japan: a foreign buyer’s guide to Tokyo’s premium market in 2026 covers the procedural sequence in detail.
On taxation, the distinction that matters most is residency status. A foreign buyer who is not a Japanese tax resident, meaning they do not hold a 住所 (juusho, domicile) in Japan, is subject to Japanese inheritance tax only on Japan-sited assets. A foreign buyer who is a Japanese tax resident, including many long-term 永住権 (eijuuken, Japanese permanent residency) holders, faces Japanese inheritance tax on worldwide assets. That distinction has significant implications for estate planning and should be reviewed with a Japanese tax adviser before any transaction above ¥500 million.
Mortgage access for non-residents is more constrained. Most Japanese megabanks, including MUFG and SMBC, require the borrower to be a Japanese resident at the time of application. Some regional banks and a small number of specialist lenders will extend financing to non-residents, but loan-to-value ratios are typically lower and documentation requirements are more extensive. Cash buyers or buyers with access to offshore financing face fewer friction points at the acquisition stage.
The 2027 Inheritance Tax Reform Every Buyer Must Know
The single most consequential regulatory development for HNW buyers of luxury homes in Tokyo in 2026 is a rule change that does not take effect until January 1, 2027. Published on December 19, 2025 as part of the 令和8年度税制改正大綱 (Reiwa 8 Tax Reform Outline), the amendment to the 相続税法 (souzokuzeihou, Inheritance Tax Act) directly targets a strategy that many wealthy buyers, both Japanese and foreign, have used for years.
Under the existing framework, rental properties are valued for inheritance tax purposes using 路線価 (rosenka, the published roadside land price), which typically produces an assessed value of roughly 40% of market price when rental discounts are applied. A ¥1 billion property assessed at ¥400 million for inheritance tax purposes represents a significant compression of the taxable estate.
From January 1, 2027, rental properties acquired within five years of the owner’s death will no longer qualify for that compressed valuation. The new default is approximately 80% of acquisition price. In cases the tax authority deems egregious, the assessed value rises to 100% of market value with no discount.
The before-and-after arithmetic is direct. On a ¥1 billion property:
| Pre-Reform | Post-Reform (from Jan 1, 2027) | |
|---|---|---|
| Inheritance tax assessed value | ¥400 million | ¥800 million |
| Reduction from market | ¥600 million | ¥200 million |
The strategy’s effectiveness is reduced to roughly one-third of its prior value for recently acquired properties.
Two categories remain under the old rules. Land owned for more than five years on which a new rental building is subsequently constructed continues to be assessed under the traditional 路線価 method. Properties held for five or more years before the owner’s death also retain the traditional valuation. The reform is specifically targeted at short-hold acquisition strategies.
Also affected are 不動産小口化商品 (fudousan koguchika shouhin, fractional real estate investment products), which are assessed at near-market value regardless of holding period under the new rules. Buyers who have been advised to use fractional products as an inheritance-tax vehicle should revisit that advice with a qualified Japanese tax specialist before the end of 2026.
For buyers who are structuring a Tokyo acquisition with any estate-planning dimension, the five-year holding horizon is now a hard planning parameter.
Selecting a Property and an Adviser
The practical challenge for a foreign buyer approaching luxury homes in Tokyo is not finding properties. Listings at ¥300 million and above appear across platforms including Sotheby’s International Realty’s Tokyo portfolio, which carries several hundred active listings across the city at any given time. The challenge is navigating the transaction itself: a statutory process conducted almost entirely in Japanese, with a licensed specialist required by law to be present at the 重要事項説明 disclosure meeting, a 手付金 (tetsuke-kin, earnest-money deposit, typically 10% of the purchase price) due at contract signing, and a 登記 (touki, the transfer of legal title recorded at the Legal Affairs Bureau) that must be filed correctly to protect the buyer’s ownership.
Most Tokyo agencies route foreign clients through English-speaking salespeople for viewings and then introduce a 宅建士 (takken-shi, Japan’s licensed real-estate transaction specialist) only at the mandatory signing stage. That model creates a gap: the person who understood the client’s brief and conducted the negotiation is not the person with legal authority over the transaction. Koukyuu operates differently. A licensed 宅建士 personally handles every stage of every engagement, from the initial consultation through due diligence, negotiation, contract, and signing. The agency works exclusively on transactions of ¥300 million and above, and clients receive a curated shortlist built around a private brief rather than access to a generic database.
