The 5 Things Nobody Tells You Before Buying Your First Property in Japan

TL;DR: Japan’s property market is foreigner-friendly at the legal level but has structural quirks that genuinely surprise first-time buyers. Repair fund deficits, pre-1981 earthquake standards, Japanese inheritance law for overseas heirs, the reality of property manager English capabilities, and the age-value relationship in condos are the five areas where preparation directly saves money.

A client — sharp, done deals in London and Sydney — closed on a Shibuya 2LDK last year. Three months later: “Why did no one mention the building had a ¥4.5M repair fund deficit?”

It was in the disclosure documents. He’d received them. He just didn’t know what to look for. That’s the gap this letter closes.

Why Is the Repair Fund Balance the First Number You Should Check?

Every condominium in Japan has two types of monthly fees: a management fee and a repair reserve fund. The repair reserve fund accumulates over years to cover major works — exterior waterproofing, elevator overhauls, plumbing, structural repairs. In a healthy building, it’s substantial.

Many buildings, it’s not.

Japan has a known structural problem with repair fund underfunding. Monthly contribution rates were set decades ago and never revised upward fast enough. In older Tokyo buildings, I’ve seen reserves sitting at around 30–40% of what the long-term repair plan actually requires.

When the fund runs short, the owners’ association has two options: raise monthly contributions (which lowers the net yield of your investment) or levy a special assessment. Special assessments of ¥500,000–¥3,000,000 per unit are not unusual in older buildings facing major repair cycles.

The Important Matters statement — the mandatory disclosure document — will show the current balance, monthly contribution amount, and whether a special assessment has been levied recently. Read it. Ask your licensed agent to explain the long-term repair plan. A building with ¥200M in reserve and ¥300M in planned works over the next decade is a different investment than one with ¥400M in reserve for the same plan.

What Does the 1981 Earthquake Standard Actually Mean for Your Purchase?

Japan revised its Building Standards Law in 1981 to require higher seismic resistance in new construction. Buildings constructed under the pre-1981 standard are legally usable and widely inhabited. The risk profile is genuinely different.

The 1995 Kobe earthquake caused disproportionate damage to pre-1981 structures. Documented, not disputed. The 2011 Tohoku earthquake added further data points.

For foreign buyers, the practical implications:

Pre-1981 buildings often trade at a discount — sometimes a meaningful one in central wards. If you’re buying for price per square meter in areas like Minato or Chiyoda, you may be looking at some older stock. Know what you’re getting.

Post-1981 buildings meet the standard designed to prevent collapse in a major earthquake. Post-2000 buildings meet an even higher standard for timber-frame construction specifically.

For a newer apartment in a building completed 2000 or later: generally lower seismic concern. For a 1970s building near a river in Edogawa ward: different conversation.

This matters for insurance, for eventual resale, and for your own peace of mind. Don’t avoid older buildings categorically. Price the risk correctly.

How Does Japanese Inheritance Law Affect Foreign Property Owners?

This one surprises almost every first-time foreign buyer. Most don’t find out until they’ve already purchased.

If you own Japanese real estate and you die, the property goes through Japanese estate proceedings — regardless of where you were domiciled, regardless of your nationality. Japan applies the law of the deceased’s nationality to inheritance succession under Japanese private international law. The property itself is in Japan, and Japanese courts and the Legal Affairs Bureau are involved in transferring title.

For non-resident foreign owners, this typically means:

• Overseas heirs need to go through Japanese court procedures or notarized processes to transfer title
• Documents from foreign countries need to be translated, authenticated, sometimes apostilled
• Japanese statutory shares — the forced heirship portion — may interact with your home country’s succession plans in unexpected ways
• The process takes time — often 1–2 years — and costs real money in legal fees

What to do about it: before you buy, set up a structure. A jointly held property, a Japanese limited liability company with clear succession arrangements, or at minimum a clearly drafted will that covers Japanese assets. Talk to a lawyer who does cross-border estate work. Not a post-purchase nice-to-have. A pre-purchase necessity if you have heirs.

What Does “English-Speaking Property Manager” Actually Mean?

The Tokyo property management industry has genuinely improved for English speakers over the past decade. There are companies with bilingual staff who manage non-resident owner portfolios competently.

“English-speaking” covers a wide range of realities.

On one end: a full-service firm with English lease agreements, monthly statements in English, a dedicated English-language owner portal, and staff who can explain tenant complaints and repair quotes clearly.

On the other end: one staff member who handles all English inquiries, works off a translated template for the monthly statement, and responds to complex questions by sending you a Japanese document to figure out yourself.

When evaluating management companies, ask:

• How many non-resident owners do you currently manage?
• Can I see a sample English-language monthly statement?
• Who handles maintenance coordination? Is that in-house or subcontracted?
• What’s the current vacancy rate in the ward where my property is?

Don’t pay a premium for “English support” that’s one overextended person with Google Translate.

Typical management fees in Tokyo run around 3–5% of monthly rent. Cheaper isn’t always worse, but below 3% often means service is thin.

Why Do Condos Depreciate Differently in Japan Than Back Home?

This one is structural.

Japanese tax law depreciates wooden buildings over 22 years and reinforced concrete (RC) buildings over 47 years. The accounting framework and cultural expectation of building lifespan in Japan has historically been much shorter than in the UK, US, or Australia — where a 100-year-old building can still command premium prices.

The practical effect: in many Japanese markets, the value of a condominium unit on the resale market has been heavily driven by building age. A 30-year-old RC building in central Minato ward can trade at a significant discount per square meter compared to a 5-year-old building in the same block, even if both are well-maintained.

This is changing. The Japanese government and major banks have been pushing for a shift toward valuing actual building condition rather than age alone. The policy direction is clear. The market hasn’t fully followed yet.

What this means for buyers: buying a newer building gives you a slower depreciation curve on resale value. Buying an older building at a discount can still make yield sense if you’re holding for cash flow and not expecting appreciation. Know your strategy.

The age thing also interacts with the 1981 seismic standard: a building from 1983 is post-standard but still 40+ years old in 2026. That affects resale financing options for future buyers — some lenders won’t mortgage buildings with fewer than 10 years of remaining statutory life.

Where This Goes Wrong

• Buying on the Important Matters statement explanation alone without having your licensed agent pull the long-term repair plan and fund balance independently
• Assuming the earthquake resistance is fine because the building “looks well maintained”
• Buying jointly with a spouse or partner without setting up a Japan-specific estate plan for both of you
• Selecting a property manager at closing under time pressure rather than vetting them in advance
• Buying a 2006 building expecting 2006 appreciation trajectory in 2026

FAQ

Q: How do I find the repair fund balance before making an offer? A: Ask the listing agent. They’re required to disclose it in the Important Matters statement, but you can request the figure informally at the viewing stage. If they don’t know it or can’t get it easily, that itself tells you something about the listing.

Q: Is there a way to check a building’s earthquake resistance before I buy? A: Yes. Buildings completed after June 1981 meet the new standard. For older buildings, you can request a seismic assessment report if one has been done. Some sellers have it; many don’t. You can commission one yourself for typically around ¥200,000–¥500,000. Whether it’s worth it depends on the price point.

Q: Can I choose my own property manager or does the building have a designated one? A: The building has a designated management company for common areas and building-wide services. That’s fixed — you pay the management fee to them regardless. Your property manager for leasing and tenant relations is separate, and you choose them. Don’t confuse the two.

Q: Do I need a Japanese will? A: Not strictly required, but strongly recommended if you own Japanese assets. A Japanese will compliant with Japanese law makes the estate transfer much smoother for your heirs. A notarized will is the most robust format.

Q: What’s the minimum building age I should target if I want to resell easily in the future? A: No fixed rule. For lender-friendly resale, a building with 10+ years of remaining statutory life at the time of your eventual sale is a practical floor. A 2000-era building in 2026 gives you roughly 21 years of remaining statutory life under RC depreciation — still viable. A 1990 building has fewer options.
