If you’re living in Japan long-term and still keeping all your money in a Japanese bank account earning 0.001% annual interest, I want to gently tell you: you’re leaving serious money on the table. Investing in Japan as a foreigner is more accessible than most expats realize, and over the past five years working with international professionals and expat-focused startups in Tokyo, I’ve watched too many people delay getting started simply because they didn’t know where to begin. This guide will fix that.
Can Foreigners Actually Invest in Japan?
The short answer is yes — and more easily than you might think.
As long as you’re a registered resident of Japan (meaning you have a valid Residence Card / 在留カード and are enrolled in the Jūminhyo / 住民票 resident registration system), you are legally permitted to open brokerage accounts and invest in Japanese financial markets. Your visa category doesn’t matter much here — whether you’re on a Work, Spouse, or Permanent Resident visa, the eligibility criteria are essentially the same.
The Financial Services Agency (FSA / 金融庁), Japan’s financial regulatory body, governs investment accounts and tax-advantaged programs available to residents. Their official guidelines confirm that foreign nationals with valid residency status have access to the same retail investment products as Japanese citizens, including the popular NISA program.
NISA: The Tax-Free Account You Should Open First
If I had to give one piece of advice to every foreigner settling into life in Japan, it would be this: open a NISA (少額投資非課税制度) account as soon as you can.
NISA is Japan’s tax-advantaged investment account, similar in concept to an ISA in the UK or a Roth IRA in the US. As of 2026, the reformed “New NISA” system — which launched in January 2024 — allows residents to invest up to ¥1.8 million per year across two account types: the Tsumitate (積立) portion capped at ¥600,000 annually for regular contributions, and the Seichō (成長) growth portion capped at ¥1.2 million annually for lump-sum investments. All gains and dividends within these limits are completely tax-free.
The lifetime contribution limit under New NISA is ¥18 million, which is a substantial upgrade from the old system. For long-term residents, this is one of the most powerful wealth-building tools available in Japan.
Which Brokerage Should You Use?
When I helped a friend from the UK set up her investment account in 2023, we compared nearly every major brokerage available to English speakers. The two I recommend most consistently are SBI Securities (SBI証券) and Rakuten Securities (楽天証券). Both offer English-language support options, low transaction fees, and NISA account functionality. SBI Securities is particularly strong for index fund options, while Rakuten Securities integrates neatly with the Rakuten ecosystem if you already use Rakuten Bank or Rakuten Card.
For those who prefer a fully English-language experience, Interactive Brokers Japan is another solid option, especially for accessing international markets beyond Japan.
What to Actually Invest In
Most foreign residents I speak with in Tokyo are best served by keeping things simple. Japan has excellent options for low-cost index investing.
Investment trusts (投資信託 / tōshi shintaku) that track global indexes — such as the eMAXIS Slim 全世界株式 (All Country) fund — are among the most popular choices for NISA accounts. This fund tracks global equities across developed and emerging markets, has an extremely low annual fee of approximately 0.05775%, and requires a minimum investment of just ¥100. It’s where a large portion of my own Tsumitate NISA contributions go each month.
If you’re interested in Japanese equities directly, the Tokyo Stock Exchange (TSE / 東京証券取引所) is the main marketplace, and both SBI and Rakuten give you straightforward access to individual stocks and ETFs listed there.
For those with US income or assets, be mindful that you’ll want to consider funds that minimize US-source dividends to keep your tax situation clean across two jurisdictions — but that’s a conversation worth having with a tax professional.
What Foreigners Often Get Wrong
I’ve noticed that many foreigners make the same handful of mistakes when approaching investing in Japan, and most of them are avoidable.
Assuming they’re not eligible. Many expats believe their visa status prevents them from opening investment accounts. It doesn’t — residency registration is what matters, not your visa type.
Confusing a NISA account with a regular brokerage account. You must actively select the NISA wrapper when opening your account and when placing trades. Simply opening an account at SBI or Rakuten doesn’t automatically make your investments tax-free. I’ve spoken with people who invested for over a year without realizing their gains were taxable because they never activated the NISA designation.
Ignoring the US-Japan tax treaty implications. If you’re an American citizen living in Japan, you face a unique situation: the IRS still requires you to file US taxes regardless of where you live. Certain investment structures in Japan — including some investment trusts — can be classified as PFICs (Passive Foreign Investment Companies) under US tax law, which come with punishing tax treatment. Americans should consult a dual-qualified tax advisor, such as those listed through the American Chamber of Commerce in Japan (ACCJ), before investing.
Leaving Japan without a plan. If you close your NISA account when you leave Japan, you lose the tax-free status on any unrealized gains at that point. Plan your exit strategy in advance.
FAQ
Do I need to speak Japanese to open a brokerage account in Japan?
Not necessarily. SBI Securities and Rakuten Securities both have English support options, and their account opening processes include some English guidance. That said, having basic Japanese reading ability — or a Japanese-speaking friend — makes the process significantly smoother.
Can I open a NISA account on any visa?
Yes, as long as you are registered as a resident in Japan and have a valid Residence Card. Short-stay tourist visas do not qualify. You must be an official resident with a Jūminhyo.
What happens to my NISA account if I leave Japan?
You must notify your brokerage when you leave Japan. You can no longer make new NISA contributions once you’re no longer a resident, and you have up to five years before you must move your holdings to a taxable account or sell them. Plan accordingly before your departure.

Conclusion
Investing in Japan as a foreigner is genuinely accessible, and the New NISA system introduced in 2024 makes it one of the better tax-advantaged environments for long-term residents anywhere in Asia. My honest recommendation: start with a NISA account at either SBI Securities or Rakuten Securities, automate a monthly contribution into a low-cost global index fund like eMAXIS Slim All Country, and revisit your strategy once a year.
Don’t let the paperwork or language barrier talk you out of starting. The hardest part is opening the account — after that, it largely takes care of itself.
