Azabu Apartment Market Overview: Pricing and Location

Azabu (麻布) in Minato-ku (港区) has consolidated its position as Tokyo’s most expensive residential neighborhood for foreign buyers, with active listings in the Nishiazabu (西麻布) and Minamiazabu (南麻布) corridors commanding unit prices of approximately ¥4.77 million per square meter as of April 2026. A 132.09 square-meter freehold condominium in Nishiazabu 4-chome recently listed at ¥630 million, while a 101 square-meter unit in Mita Garden Hills (also Minato-ku) reached ¥730 million. Smaller units, such as a 56 square-meter property in City Tower Azabujuban, trade at ¥295 million. The neighborhood’s appeal to high-net-worth foreign residents stems from three factors: proximity to Roppongi Hills and Azabudai Hills for business and dining, direct Oedo Line and Namboku Line access to central Tokyo, and established expatriate infrastructure dating back three decades.

Rental yields in the Azabu market remain compressed. A newly completed 41.3 square-meter unit in Refir Orbe Azabusendaizaka (Minamiazabu 1-chome), finished in February 2025, commands ¥303,000 per month, equivalent to a gross yield of approximately 4.5 percent on a ¥80 million purchase price. This compression reflects both the neighborhood’s residential prestige and the structural reality that Azabu apartments rarely serve as income-producing assets for foreign owners; they are overwhelmingly held for personal use or long-term capital appreciation.

Yen depreciation persistence, combined with Asian high-net-worth asset-diversification demand, has made Minato-ku’s Azabu sub-market a near-daily transaction zone for foreign buyers since 2024. This is no longer exceptional. The neighborhood now accounts for approximately 8 to 12 percent of all luxury residential transactions in central Tokyo involving non-resident purchasers.

Fixed Asset Tax and City Planning Tax for Azabu Property Owners

Once you acquire an Azabu apartment, two annual property taxes apply immediately: 固定資産税 (kotei-shisanzei, fixed asset tax) and 都市計画税 (toshi-keikakuzei, city planning tax). Both are levied on the 固定資産税評価額 (assessed value), which is typically 70 to 80 percent of market value for residential property.

In Tokyo’s 23 special wards, the standard rates are:

• Fixed asset tax: 1.4 percent of assessed value
• City planning tax: 0.3 percent of assessed value (Tokyo applies the statutory ceiling)

For a ¥630 million Azabu apartment with an assessed value of approximately ¥450 million, annual fixed asset tax would be ¥6.3 million, and city planning tax ¥1.35 million, totaling ¥7.65 million per year. These payments are due in four quarterly installments (April, July, December, February) and are non-negotiable regardless of occupancy or rental status.

However, the 2026 tax reform (令和8年度税制改正, FY2026 Tax Reform) introduced a significant relief measure for new-build properties. Condominiums completed between April 1, 2026 and March 31, 2031 qualify for a 50 percent reduction in fixed asset tax for five years, provided the building meets fire-resistant structural standards (which all Azabu towers do). The minimum floor-area threshold for eligibility was lowered from 50 square meters to 40 square meters in 2026, broadening the relief to smaller units. A new 56 square-meter City Tower Azabujuban unit would thus pay only ¥1.4 million in annual fixed asset tax during its first five years of ownership, rather than ¥2.8 million.

The Parkhouse Hiroo Hazawa 798 million yen property illustrates how new-build tax relief applies across Minato-ku’s luxury market.

Land value within the condominium’s assessed value also receives a permanent reduction. Up to 200 square meters of residential land (小規模住宅用地, small-scale residential land) is assessed at only 1/6 of its true value for fixed asset tax purposes and 1/3 for city planning tax. Land over 200 square meters is assessed at 1/3 for fixed asset tax and 2/3 for city planning tax. Since most Azabu apartments are small to mid-size units, the 200 square-meter threshold is rarely exceeded, meaning the full 1/6 reduction applies to the land component of your assessed value indefinitely.

Non-Resident Owner Tax Obligations and Withholding Requirements

As a foreign buyer without permanent residency (永住権, eijuuken), you are classified as a 非居住者 (non-resident) for Japanese tax purposes, even if you spend six months per year in the Azabu apartment. This classification triggers two critical withholding obligations that most foreign buyers discover only at signing or, worse, after sale.

Rental Income Withholding

If you rent out your Azabu apartment to a corporate tenant (such as a relocation company providing 社宅, corporate housing), the tenant must withhold 20.42 percent of gross rent and remit it directly to the 国税庁 (NTA, National Tax Agency). You receive only the net amount. For example, a ¥500,000 monthly rental becomes ¥397,900 net to you; the tenant pays ¥102,100 to the NTA.

If the tenant is an individual renting for their own residential use (not a corporate sub-let), the withholding does not apply. However, if a management company collects rent on your behalf and fails to instruct corporate tenants to withhold, the management company becomes liable for the 不納付加算税 (non-payment surcharge) and 延滞税 (delinquency interest), which can exceed 30 percent of the unpaid withholding amount. This liability is not automatically passed to you, but it creates operational friction and potential disputes.

Sale Proceeds Withholding

When you sell the Azabu apartment to a Japanese buyer, the buyer must withhold 10.21 percent of the purchase price and pay it to the NTA before the transaction closes. On a ¥630 million sale, the buyer withholds ¥64.3 million; you receive ¥565.7 million. The withheld amount is credited against your Japanese income tax liability for the year of sale, but only if you file a 所得税確定申告 (income tax return) with the NTA. If you do not file, the withholding is simply forfeited.

Failure by the buyer to withhold creates a personal tax liability for the buyer that is practically unrecoverable once you have left Japan. This is why reputable Tokyo real estate agents and lawyers now verify non-resident status at the initial consultation and confirm withholding procedures in writing.

Tax Agent (納税管理人) Requirement

Before you can file an income tax return in Japan as a non-resident, you must appoint a 納税管理人 (tax agent), typically a Japanese accountant or tax attorney with an office address in Japan. The tax agent receives all NTA correspondence, files your 所得税確定申告 (income tax return), manages 固定資産税 payments, and receives refunds on your behalf. As of 2026, best practice requires a separate written contract (distinct from your property management agreement) specifying the tax agent’s scope of work, fee structure, and term.

Tax agent fees range from ¥80,000 to ¥200,000 per year, depending on the complexity of your tax situation. If you own multiple properties or have Japanese-source income, fees may exceed ¥300,000. This cost is deductible as a business expense in Japan.

Inheritance Tax Strategy: Azabu Property as an Estate-Planning Tool

For foreign buyers with substantial net worth, Azabu property can serve as an efficient inheritance tax planning instrument, though the rules have tightened since 2024.

Japanese inheritance tax is levied on the assessed value of property, not its market value. For residential real estate, the assessed value is typically 50 to 70 percent of market price. A ¥630 million Azabu apartment might have an assessed value of ¥380 to ¥440 million for inheritance tax purposes. If the property is tenanted (generating rental income), the building itself is assessed at only 35 to 50 percent of its assessed value, and the land is assessed at 60 to 70 percent of its market value. This creates a significant discount.

The 小規模宅地等の特例 (small-scale land special provision) applies to rental property land up to 200 square meters, reducing the assessed value by 50 percent for inheritance tax purposes. For a Minato-ku apartment where the land component is valued at ¥150 million, this provision reduces the taxable value to ¥75 million, a ¥75 million discount to your estate.

However, the tower-mansion rule tightening (effective 2024, ongoing in 2026) has constrained this strategy. The 区分所有マンション相続税評価方法 (condominium inheritance tax valuation method) was reformed so that high-floor units can no longer generate the dramatic evaluation gap that made タワマン節税 (tower-condo tax minimization) attractive. Units above the 25th floor in a 40-story tower now receive a modest premium (rather than a discount) in their assessed value, and units below the 5th floor receive a modest discount. The net effect is that inheritance tax planning through tower-mansion selection is no longer a reliable strategy.

Before purchasing an Azabu apartment with inheritance tax planning in mind, consult a 相続専門税理士 (inheritance tax specialist) to confirm the current assessed value methodology and whether the property qualifies for the small-scale land reduction. Grand Hills Moto-Azabu 378 million yen property represents a mid-market entry point for buyers evaluating this strategy.

Compliance and Legal Requirements for Foreign Buyers

Foreign buyers purchasing Azabu apartments face four compliance layers that do not apply to Japanese residents.

Anti-Money Laundering (犯収法)

The 犯収法 (Act on Prevention of Transfer of Criminal Proceeds) requires all real estate agents and lawyers to conduct full know-your-customer (KYC) documentation. You must provide: a サイン証明書 (notarized signature certificate) from your home country’s embassy or consulate, an アポスティーユ-certified (Hague Convention apostille) proof of address, and a valid passport. The notarized signature certificate confirms that the signature on your purchase contract matches your official signature on file with your government. Obtaining this document typically requires a visit to your embassy or consulate and takes 2 to 4 weeks. The apostille is obtained from your home country’s foreign ministry or equivalent authority and certifies the authenticity of the address document.

Failing to provide these documents before the 重要事項説明 (juuyou-jikou-setsumei, statutory pre-contract disclosure meeting) will delay closing by 4 to 8 weeks. Reputable agents now request these documents at the initial consultation.

Vacant Property Law (空家法)

The 空家法 (Vacant House Special Measures Act), enacted in 2015 and tightened in 2023, requires owners of residential property to maintain them in habitable condition. If an Azabu apartment is designated as a 特定空家 (designated vacant property) due to long-term abandonment, structural deterioration, or security issues, the property loses its 住宅用地 (residential land) tax reduction. Fixed asset tax on the land portion jumps from 1/6 of assessed value to the full assessed value, increasing your annual tax bill by 5 to 8 times. As a foreign owner living overseas, you are at higher risk of this designation if the property sits unoccupied for more than two consecutive years without a management company inspecting it monthly.

To comply, retain a 不動産管理会社 (property management company) with a written contract specifying monthly inspections, utility maintenance, and reporting to you. Costs range from ¥15,000 to ¥30,000 per month.

Pre-Approval Clause for Repairs

Most standard property management contracts require owner approval for any repair exceeding ¥100,000. For overseas owners in different time zones, this creates operational delays. Recommend inserting a 事前承認枠 (pre-authorisation clause) allowing the management company to execute repairs up to ¥300,000 without seeking your approval, provided they notify you within 48 hours and provide a photograph and invoice. This protects the property from water damage, structural issues, or security breaches that could escalate if left unaddressed while awaiting your email response.

Repatriation and Currency Risk

While Japan imposes no capital controls on foreign buyers selling property, the 国税庁 (NTA) requires that sale proceeds remain in Japan for at least 12 months if you intend to claim a 居住用財産の3,000万円特別控除 (3 million yen capital gains exclusion for residential property). If you immediately repatriate sale proceeds, you may forfeit this exclusion. Additionally, the withholding tax (10.21 percent of sale price) is credited against your Japanese income tax only if you file a return; if you repatriate and do not file, the withholding is lost. Currency fluctuations between the yen and your home currency can also erode returns; a ¥630 million sale in April 2026 (yen at approximately 148 to the USD) may net fewer dollars if the yen weakens to 155 by the time you repatriate nine months later.

The 2026 New-Build Tax Reduction and Timing Strategy

The FY2026 Tax Reform extended the new-build 固定資産税 (fixed asset tax) half-reduction measure, now covering completions through March 31, 2031. This creates a time-sensitive opportunity for foreign buyers.

General housing (residential floor area of 120 square meters or less) qualifies for a 50 percent fixed asset tax reduction for three years. Condominiums in fire-resistant structures (3 floors or higher, which includes all Azabu towers) qualify for the same 50 percent reduction but for five years. Certified 認定長期優良住宅 (long-life quality housing) properties receive a 50 percent reduction for seven years.

The minimum floor-area threshold for eligibility was lowered from 50 square meters to 40 square meters in 2026, making smaller luxury units newly eligible. A 45 square-meter Azabu apartment completed in June 2026 would pay only 50 percent of normal fixed asset tax from 2026 through 2030, then full tax from 2031 onward.

For a buyer planning to hold the property for 10 years or longer, purchasing a new-build unit in 2026 or 2027 offers approximately ¥3 to ¥5 million in cumulative tax savings over the five-year reduction period. Older resale units (built before 2021) do not qualify for this relief.
