A 47-year-old US Citizen was Told She Couldn’t invest in Japan
This consultation came from an in-person FP session booked via our website, answered by financial planner Yoshiko Nakamura.
Client: Female (47), American citizen, single, with Permanent Residency in Japan (living in Japan for 15 years).
The consultation:
During her early years in Japan, her income was low and her life was far from stable. But five years ago, she successfully changed careers. Her income rose and stabilized , allowing her to buy an apartment and build ¥10 million in savings.
Yet, because of the strict “PFIC” tax rules for US citizens, she had been told she couldn’t invest in Japanese stocks or mutual funds without facing massive penalties from the IRS.
For years, she touched nothing. But with the weak Yen and rising market, she watched her cash savings lose value daily. Desperate for a solution, she searched online and came to us, eager for an in-person consultation.
The fear of the “IRS Penalty
“When we looked at her situation together, the root of her paralyzing fear was the US tax classification known as PFIC (Passive Foreign Investment Company).
Under US tax laws, any foreign (non-US) mutual funds or ETFs are subject to punitive taxation (nearly 40%) and extremely complex annual reporting (Form 8621).
This is why NISA’s “Tsumitate” (installment) slots and standard Japanese investment trusts are practically off-limits for Americans.
She had asked friends, searched online, and even asked the US tax accountant who prepares her annual tax filings. Everyone gave her the same answer: “Don’t touch anything in Japan. The IRS penalties are too high.”
So, she kept her ¥10 million entirely in cash. But keeping everything in cash carries its own risk—especially in an era of inflation and a weak Yen. Doing nothing was no longer a safe option.
A 5-minute solution to a 15-year worry
Before looking at the numbers, I always want to find a realistic, safe path that respects both Japanese tax benefits and US tax compliance. The breakthrough actually took less than five minutes. I handed her a simplified, black-and-white English guide sheet we use for US citizens.
The solution lies in two specific choices:
1. Buying “Japanese Individual Stocks” via NISA’s Growth Slot
While foreign mutual funds are treated as PFICs, individual shares of operating business corporations (e.g., Toyota, Sony) are not classified as PFICs.
By using NISA’s “Growth Investment Slot,” she can buy Japanese individual equities. On the Japanese side, her gains and dividends are 100% tax-free. On the US side, she simply reports them as standard investment income—no punitive PFIC penalties, no Form 8621.
2. Using Interactive Brokers Securities Japan (IBSJ)
Most domestic Japanese brokers restrict US citizens or lack English support. IBSJ, however, is designed for this: It supports NISA accounts for Japanese individual stocks. The entire platform and support are in English. They provide the necessary annual reports that her US tax accountant needs, keeping her tax preparation simple and affordable.
A sense of relief after years of isolation
As I walked her through this path, her expression visibly softened, and her eyes welled up with tears of relief.
“I’ve been carrying so much anxiety about my future all by myself,” she said. “No matter who I asked, or how much I searched online, no one could give me a clear, actionable answer. My friends couldn’t help, and even my US tax accountant simply told me to avoid investing in Japan. To think that after all these years of worrying, the solution was this straightforward and took only five minutes to explain.”
In financial planning, our job is often to calculate numbers and run projections. But sometimes, the most valuable thing we can offer is simply peace of mind—helping a client lift a quiet, heavy burden they have been carrying alone for years.
Key takeaways
Avoid non-US mutual funds/ETFs:
For US citizens, funds based outside the US (such as Japanese investment trusts) trigger severe PFIC tax penalties from the IRS.
Use Individual Stocks & US-domiciled ETFs: Individual shares (both Japanese and US companies) and US-domiciled ETFs (like VOO) are exempt from PFIC rules, making them perfectly safe to hold.
Use NISA through IBSJ:
By using Interactive Brokers, you can invest in these safe assets within Japan’s tax-free NISA, while easily obtaining the reporting documents required for your annual US tax return.
The following sessions
Investing in Japan was her primary concern, but we still have other important areas to cover, such as paying off her mortgage, planning for retirement, and estate planning. We will discuss these in detail once she opens her NISA account and starts investing.
I look forward to meeting her again to support her long-term life in Japan.

If you’re a US citizen in Japan and find yourself carrying a vague sense of worry about your financial future, or if you’ve simply been told you cannot invest, you don’t have to sort through these complex tax rules alone.
We can start by looking at your numbers and finding a clear, compliant path that feels right for you.
