Inheritance in Japan

I have advised many long-term residents in this marvelous country about inheritance in Japan. It can be complicated, costly, and it has a nasty habit of sneaking up when people least expect it. This is the fourth article in the series.

Below are the questions I hear most often. If they have been scratching at the back of your mind, resolve them with a phone call today. I do not know of anyone else who regularly prepares dual-jurisdiction Last Wills & Testaments that actually work on both sides of the Pacific (or the Atlantic). That is precisely why I write these pieces.

1. “Can Japan really tax me on an inheritance from my parents back home — money and property that never once touched Japanese soil?”

Yes. And this is the single most common shock.

Japan does not tax the estate the way the United States and most other jurisdictions do. Japan taxes the heir. The recipient.

I had a client once, an American who had lived here for years, whose father died in Ohio. The estate was ordinary by American standards: a house, a brokerage account, some cash. Nothing Japanese about any of it. Six months later a Japanese tax notice arrived. He sat in my office and said, almost laughing, “They want tax on my father’s driveway.” They did. Because he lived here, Japan treated what he received as taxable in his hands, wherever those assets sat.

You become exposed from day one if you hold permanent residence, a spouse visa, or teijūsha status. Work-visa holders still enjoy a limited shelter. It lasts only until they have had a Japanese address for more than ten of the last fifteen years. Cross that line and the worldwide net closes.

Many people I know discover this only after a parent has died. By then the Japanese tax office already has a claim, the ten-month clock is running, and you are scrambling.

2. “My spouse visa (or permanent residence) shelters my income tax. Doesn’t it protect me on inheritance too?”

No. This is the second most dangerous misconception.

The very status that gives you security and the right to stay — permanent residence or a spouse visa — simultaneously strips away the inheritance shelter that work-visa holders still enjoy (for now). From the moment Immigration grants you that status, you are worldwide for inheritance and gift-tax purposes. There is no grace period.

I watched a client switch to a spouse visa because it made daily life simpler — school, banking, the sense of finally belonging. Two years later her mother died in Canada. Only then did we sit down and map her exposure. She looked at me and said, “I thought the visa was the safe choice.” For living here, it was. For dying and inheriting, it is the opposite.

I have seen this pattern more than once. People make a sensible immigration decision and accidentally open their entire future estate, and any inheritances they might receive, to Japanese taxation. The rates climb to 55 percent above a very modest deduction.

3. “How bad can the tax actually be — and when is it due?”

Japan’s basic deduction is ¥30 million plus ¥6 million per statutory heir. After that the rates start at 10 percent and rise quickly to 55 percent. Cross-border estates that generate zero estate tax in your home country routinely produce very real Japanese tax bills. Of the G-20 countries, none are more aggressive than Japan on this point. Lots of complaints, but what are you, a foreigner, going to do? Take it on the chin is what you’re going to do.

The formal report and the payment are both due within ten months of the death. Most countries’ probate processes take longer than that. Japanese tax does not wait. Miss the deadline and additional tax and delinquency charges begin to accumulate while the family is still grieving and the overseas assets are still locked in probate. It is a terrible mess.

I had a client whose brother died in California. The California probate was still grinding along at month nine. The Japanese filing date did not care. We were preparing the Japanese return on assets that had not yet been released. That is the clock. It is not theoretical.

Then there is the carry-over of cost basis. Japan does not reset the value of inherited property to the date of death. When the heir later sells appreciated stock, or a house that rose in value over twenty years, Japan taxes the full historical gain — on top of the inheritance tax already paid. Are you upset yet?

4. “I already have a perfectly good Will from my home country. Isn’t that enough?”

Almost never.

An isolated foreign Will must still be translated, authenticated, and submitted to the Japanese Family Court. That typically takes four weeks or more if you can get it organized at all. Banks freeze accounts. Real-estate registries stall. Statutory heirs, including children from previous relationships, can still claim their iryūbun, the reserved portion, regardless of what the foreign Will says. None of that addresses the tax exposure created by your Japanese residency.

I once sat with a widow who produced a beautifully drafted American Will, notarized, witnessed, the whole shebang. The bank would not release a yen until the Family Court had finished with it. Her late husband’s children from an earlier marriage appeared, as the Civil Code allows them to do. The document that had given her such comfort in Houston became, in Tokyo, a starting point for an argument rather than the end of one.

A single-jurisdiction document leaves the two systems fighting each other. The practical solution is a coordinated meld of instruments: one that satisfies Japanese formal requirements and choice-of-law rules, and one that works cleanly in your home country. They must be drafted so they do not contradict each other, and so the tax and procedural burdens are minimized on both sides. That is the dual-jurisdiction Will I prepare with you. Valid in both countries, doing double duty, solving dozens of issues for your heirs and preserving what you built. Saves you tremendously.

5. “What about trusts? I set one up years ago.”

Foreign trusts are frequently disregarded by Japanese tax authorities when the settlor or the beneficiaries have a sufficient connection to Japan; I would say almost always. Assets inside the trust can still be pulled into the Japanese taxable estate. Domestic Japanese trust vehicles exist, but they are rigid and often unsuitable for the typical foreign family’s needs.

I had a client who had spent a small fortune on a U.S. living trust and arrived in my office with the binder still warm from the attorney’s office in California… double-spaced, big fonts. He wanted me to tell him he was steel-vault protected. I could not. That beautiful, soul-soothing structure works so well in the United States or the United Kingdom. It will not shield you and your heirs here. Do not assume it will.

6. “I’ve been here a long time but I’m planning to leave eventually. Once I’m gone, the problem goes away, right?”

Can’t you already guess the answer by now?

The ten-year look-back and the status of your heirs can keep the Japanese claim alive even after you have left. If an heir remains resident in Japan, or if you yourself were resident within the relevant window, the tax authority can still reach worldwide assets. Leaving without a proper plan simply changes the geography of the problem. It does not eliminate it.

At this point, you don’t need to be told that Japan will look under every nook & cranny for revenue. The foreign angle is not only a particularly juicy one. It is a politically safe one to exploit, too.

A long term resident retired to Australia thinking that departing Narita was the end of the story. His dual-nationality daughter remained to pursue her career in Tokyo. When he died, she inherited. Japan of course treated the inheritance as taxable. The farm he had been so careful to keep “outside Japan” was, in fact, back in the jaws of the problem. The irony is as thick and lingering as a truly awful stink.

Why Most People Still Delay

The issue feels abstract until it is not. No one expects to die at fifty-four — the age at which actress Miho Nakayama died. Her Paris-based son later renounced a reported ¥2 billion estate rather than scramble for an estimated ¥1.1 billion in cash tax before the ten-month clock ran out. Most of the people I know do not even expect to die at all(!), at least not soon enough to require action this year. I get this all the time: “let me think about it…”

Yet every year I meet families forced into the brutal choice Japanese law deliberately creates (who else are they going to call?). They are suddenly & unexpectedly confronted with an enormous tax bill, everything is in Japanese, to be assessed and valued and PAID within ten months. This is just too much sometimes, so a fire-sell of assets or borrowing under distress arrives. The other option is to renounce the inheritance entirely and watch a lifetime of a beloved one’s work evaporate. “That’s not what Daddy intended.”

A dual-jurisdiction Will does not repeal Japanese tax law. What it does is give you the maximum control still available: clear choice-of-law provisions, coordinated distribution instructions, liquidity planning, and documents that the Japanese Family Court and your home-country courts will both accept without years of delay and conflict.

I have been doing this work for decades. I prepare the Japanese notarized instrument and coordinate the parallel home-country document so the two speak the same language. Very few practitioners handle both sides properly. That is the service.

If any of the questions above have been sitting in the back of your mind, the time to resolve them is while you are still healthy and the options remain open. The cost of a properly drafted dual-jurisdiction Will is a fraction of the cost of cleaning up the mess later. That is assuming the mess can still be cleaned up at all.

Give us a call if this is a concern.
