How Much Is Property Tax in Japan? A Fixed Asset Tax Guide

After buying property in Japan, the cost does not stop at closing — every year you will also owe fixed asset tax (固定資産税) and, in many areas, city planning tax (都市計画税). New owners often ask how much this will actually cost, how it is calculated from the price they paid, and what the prorated amount charged at closing really means. The short answer: the tax is not based on your purchase price but on a separately assessed taxable value set by the municipality, generally taxed at around 1.4% for fixed asset tax and up to 0.3% for city planning tax. In practice, special reductions for residential land and new buildings often lower the real bill significantly — and the proration of tax at closing is a customary practice, not a legal requirement, which is one of the most common points of confusion for buyers.

This guide walks through how the two taxes work, how the amount is calculated, what reductions apply, when the bill arrives, and the settlement-day pitfall to watch for. Because rates, assessed values and eligibility for reductions vary by municipality and by property, always confirm the exact figures with the local municipal tax office or a licensed tax accountant (zeirishi) before relying on them.

What is fixed asset tax, and who has to pay it?

Fixed asset tax is a municipal tax levied on anyone who owns land, buildings, or certain depreciable business assets, paid to the municipality where the property is located. Liability is fixed as of January 1 each year, a date known as the assessment date (賦課期日). Whoever is recorded as the owner in the property register and the local tax roll on that date owes the full year's tax.

This means that if you sell your property on, say, January 2, you (the seller) generally remain legally responsible for that entire year's fixed asset tax. The municipality does not automatically split the bill between the old and new owner partway through the year — a point that matters a great deal for the closing-day misunderstanding covered later in this guide.

How is city planning tax different from fixed asset tax?

City planning tax is also a municipal tax, but it applies to a much narrower set of properties. It is only charged on land and buildings located within an urbanization promotion area (市街化区域) as defined under Japan's City Planning Act — properties in urbanization control areas or outside any city planning area are generally not subject to it at all. Unlike fixed asset tax, which is a general-purpose tax, city planning tax is a purpose-specific, earmarked tax, whose revenue is meant to fund urban planning projects such as land readjustment.

Because of this, two properties in the same municipality can have very different tax bills depending on whether they sit inside or outside the urbanization promotion area. It is worth confirming this zoning classification with the municipality's city planning division before you buy.

How is the tax amount actually calculated?

Both taxes are calculated as the taxable base (generally the fixed asset tax assessed value) multiplied by the tax rate. The assessed value is not your purchase price or the current market price — it is a separate valuation the municipality determines according to national assessment standards. As a very rough guide, assessed land values are sometimes cited as roughly 60-70% of published land price benchmarks, but this ratio is only a general reference point and can vary considerably by property and municipality.

The standard rate for fixed asset tax is generally 1.4%, but this is only a baseline that municipalities may adjust by local ordinance — some set a higher rate depending on local finances. City planning tax is capped by a maximum, or restriction, rate of 0.3%, with the actual rate again set locally within that ceiling. Always confirm the actual rate applied by checking with the municipality where the property sits.

The assessed value itself is not revised every year — it is generally reassessed every three years in a process called revaluation (評価替え), reflecting changes in land prices and building depreciation. This means the tax you pay in your first year is not necessarily what you will keep paying indefinitely.

How much does the small residential land reduction actually save?

Land under a residential building qualifies for a special reduction to the taxable base. For the portion up to 200 square meters per dwelling (small-scale residential land), the taxable base for fixed asset tax is reduced to one-sixth of the assessed value, and to one-third for city planning tax. For the portion beyond 200 square meters (general residential land), the reduction is to one-third for fixed asset tax and two-thirds for city planning tax.

This reduction is substantial, which is part of why building a home on land tends to lower the ongoing tax burden compared with holding it as vacant land. However, if the building is demolished or the land no longer qualifies as residential, the reduction is lost and the tax can rise sharply, so it is worth planning for before tearing down an existing structure. The precise application can vary in detail by municipality, so it is worth confirming against your tax notice or with the local tax office.

What is the new-build reduction, and how long does it last?

Newly built homes that meet certain requirements can qualify for a temporary reduction that cuts the fixed asset tax amount itself by roughly half for a limited number of years. As a general guide, this often runs for about three years for a typical detached house and about five years for certain mid- and high-rise fire-resistant condominium buildings, with the exact period depending on the building's structure and scale, but these periods and requirements can change with tax reform, so treat them as a rough guide and confirm the current rules with the municipality or a tax accountant.

The easy trap here is assuming the discounted amount on your first notice is the permanent tax level. It is a time-limited measure: once the reduction period ends, the bill reverts to its full, uncapped amount, which can feel like a sudden increase even though nothing else about the property changed.

When does the tax notice arrive, and how do you pay?

In most municipalities, the annual tax notice for fixed asset tax and city planning tax is sent between around April and June, addressed to whoever owned the property as of January 1 that year. Owners can typically choose to pay the full annual amount in one lump sum or in four installments spread across the year, depending on what the municipality offers. Payment is made to the municipality where the property is located, and available methods vary by municipality — bank transfer, payment at a convenience store or bank counter, or online payment through Japan's local tax payment system are common options.

The notice also itemizes the assessed value, taxable base, and any reductions applied, so it is worth reviewing the full breakdown rather than just the total amount due — doing so helps avoid the misunderstandings covered next.

The rules themselves are fairly simple, but figuring out which reductions apply to your specific property, until when, and which numbers on your tax notice actually matter takes looking at your own paperwork.
