Ginza’s 2026 published land price (公示地価) reached ¥5.4 million per tsubo (3.3 square meters) for prime commercial frontage, maintaining its position as the most expensive soil in Japan. This figure, released by the Ministry of Land, Infrastructure, Transport and Tourism in March 2026, anchors Chuo Ward’s identity as both the nation’s commercial heart and its most concentrated source of property tax liability for high-net-worth owners.

The Geography: Four Districts, Two Tax Realities

Chuo City (中央区, Chuo-ku) spans 10.21 square kilometers, making it the second-smallest of Tokyo’s 23 wards after Taito at 10.11 square kilometers. Within this compressed territory sit four functionally distinct real estate markets, each with its own tax implications.

Ginza (銀座) and Nihonbashi (日本橋) form the traditional commercial core. Ginza’s 2026 route value (路線価, the National Tax Agency’s valuation for inheritance tax purposes) runs at approximately 80% of published land prices, placing even residential-adjacent properties in the ¥3-4 million per tsubo range. Nihonbashi, undergoing regeneration around the 2020-completed Nihonbashi Tower and ongoing mixed-use developments, commands ¥2.8-3.5 million per tsubo for commercial-adjacent residential. Tsukiji (築地), Tsukishima (月島), Kachidoki (勝どき), and Harumi (晴海) comprise the bay area. Harumi Flag (晴海フラッグ), the 5,632-unit condominium complex completed in 2023 on the former Tokyo 2020 athletes’ village site, reset price expectations here. Resale transactions in Harumi Flag Tower Village reported ¥850,000-¥1.2 million per square meter in early 2026, depending on floor and view corridor toward Tokyo Bay.

The tax reality bifurcates along this geography. Ginza and Nihonbashi properties face concentrated inheritance tax exposure due to high route values. Bay-area properties, while bearing lower per-square-meter valuations, often carry higher absolute tax bills due to larger unit sizes — 100-150 square meter layouts are standard at Harumi Flag versus 45-70 square meters in Ginza-adjacent vintage manshon (マンション, freehold condominium) stock.

Fixed Asset Tax and City Planning Tax: The Metropolitan Collection System

Foreign buyers frequently assume Chuo Ward, as a wealthy district, sets its own property tax rates. It does not.

Fixed asset tax (固定資産税, kotei-shisan-zei) and city planning tax (都市計画税, toshi-keikaku-zei) are collected by the Tokyo Metropolitan Government (東京都主税局, Tokyo Metropolitan Government Bureau of Taxation), not ward administrations. Chuo Ward’s tax section handles inquiries and documentation but cannot alter rates or collection procedures.

The 2026 structure:

Tax	Rate	Assessment Basis
Fixed asset tax	1.4% standard	Taxable value (typically 60-70% of market value for land, 50-60% for buildings)
City planning tax	0.3% (Tokyo’s maximum allowable)	Same taxable value, applicable only in city planning areas (nearly all of Chuo Ward)

For a ¥300 million Ginza-adjacent manshon, this translates to annual tax liability of approximately ¥2.5-3.2 million, depending on the land-to-building valuation split. Tokyo’s assessment methodology front-loads land value, meaning older buildings on prime Ginza soil retain disproportionately high tax burdens relative to their depreciated structure value.

The metropolitan collection system creates a specific friction for non-resident owners. Payment notices arrive in Japanese only. The Chuo Metropolitan Tax Office (中央都税事務所) at 03-3553-2151 handles English inquiries, but payment must proceed through designated financial institutions or the Tokyo taxes online portal, which requires Japanese-language navigation or proxy arrangement.

Resident Tax: Ward-Level Variation and the 183-Day Threshold

Resident tax (住民税, jūmin-zei) differs from property taxes in that ward administrations do set components. Chuo Ward’s 2026 structure:

• Ward tax (特別区民税): 6% of prior-year income plus ¥3,000 flat
• Metropolitan tax (都民税): 4% of prior-year income plus ¥1,000 flat

This 10% combined rate is identical across all 23 wards. Chuo Ward’s distinction lies in service delivery: multilingual pamphlets in Japanese, English, Chinese, and Korean are available at ward offices and downloadable from city.chuo.lg.jp.

The critical threshold for foreign buyers is 183 days. Exceed this in Japan during any calendar year, and you become a resident taxpayer subject to worldwide income declaration. Remain below, and Japan taxes only Japan-source income — but property ownership itself does not trigger residency. The 183-day count excludes temporary absences; a buyer who owns a Ginza apartment, visits for 60 days annually, and rents it otherwise faces no resident tax liability.

This distinction matters for mortgage qualification. Japanese banks typically require resident tax certificates (納税証明書, nozei-shōmei-sho) for income verification. Non-residents must substitute certified tax documents from their home jurisdiction, often triggering higher interest spreads or reduced loan-to-value ratios. Minato’s 16.6% land price surge has compressed these spreads in central wards as banks compete for collateral-rich borrowers, but the documentation burden remains.

Inheritance Tax: The 20% Tokyo Problem

National Tax Agency statistics consistently show Tokyo with approximately 20% of decedents subject to inheritance tax (相続税, sōzoku-zei), versus roughly 10% nationwide. Chuo Ward contributes disproportionately to this concentration.

The mechanism is route value. Published each July, these valuations determine the taxable base for inherited property. Ginza’s 2024 route values (the most recent available for 2026 estate planning) reached ¥32.4 million per square meter for the highest-grade commercial frontage — not per tsubo, per square meter.

For heirs, this creates the “cash-poor heir” scenario: land dominates estate value, liquid assets are limited, and the 6-10 month filing deadline forces distressed asset sales or high-interest bridge loans. The basic deduction of ¥30 million plus ¥6 million per statutory heir provides limited relief when a single Ginza commercial building can exceed ¥500 million in assessed value.

Foreign buyers face additional complexity. Japan’s inheritance tax applies to worldwide assets for residents and to Japan-situated assets for non-residents. A non-resident who owns a ¥300 million Harumi Flag apartment and ¥2 million in Japanese securities pays inheritance tax only on the ¥302 million Japan total. But treaty provisions vary: the Japan-U.S. estate tax treaty allows credit mechanisms, while other jurisdictions may not. Advance structuring through tokumei-kumiai (匿名組合, anonymous partnership) arrangements or Japan-based holding companies is standard practice for acquisitions above ¥500 million, though these structures carry their own fixed asset tax implications.

The Bay Area Premium: Harumi Flag and Kachidoki’s 2026 Market

Harumi Flag’s completion shifted foreign buyer attention toward Chuo Ward’s waterfront. The development’s 5,632 units across multiple towers include dedicated foreign resident support services, English-speaking management, and layouts optimized for international family configurations.

Resale dynamics as of May 2026:

• Harumi Flag Tower Village: ¥850,000-¥1,050,000 per square meter for 2LDK-3LDK units
• Harumi Flag Park Village: ¥750,000-¥920,000 per square meter, lower due to reduced bay visibility
• Adjacent Kachidoki new construction (The Kachidoki, Tokyo): ¥900,000-¥1,150,000 per square meter for tower residences above 30th floor

These prices compare to ¥1.4-1.8 million per square meter for comparable new construction in Roppongi’s tower market, making Chuo Ward’s bay area the relative value play for buyers prioritizing space over address prestige.

The tax trade-off is municipal services. Chuo Ward operates no international schools within its boundaries. The British School in Tokyo and American School in Japan require Minato or Shibuya Ward access, meaning resident tax payments to Chuo Ward do not directly fund the educational infrastructure foreign families typically require. This misalignment between tax payment and service consumption is a structural feature of Tokyo’s ward system, not specific to Chuo, but it surfaces particular friction given the ward’s high foreign resident concentration in Harumi.
