Best Forex Brokers in Japan 2026: How to Check JFSA Registration, the 25x Cap and FX Tax

Japan runs one of the most tightly defined retail FX regimes in the world. If you live there, the first question is not the spread but whether the firm is registered with the Financial Services Agency (JFSA) to deal with you. Leverage, client-money protection and even your tax rate follow from that answer.

The table of locally licensed brokers above this article comes from our broker database. This guide explains what those registrations mean and how to check them yourself.

Why JFSA registration is the first filter in Japan#

A broker that offers FX to Japan residents as a business must be registered under the Financial Instruments and Exchange Act (FIEA). The JFSA says so directly on its FX information page: even a firm that holds a financial licence abroad is prohibited from conducting financial instruments business with residents of Japan without Japanese registration.

OTC FX and CFD dealing falls under Type I Financial Instruments Business (第一種金融商品取引業). Registration is handled by the JFSA through the Local Finance Bureaus, so a registration number reads like "Director-General of the Kanto Local Finance Bureau (FIBO) No. 1662" (関東財務局長(金商)第1662号). That particular number belongs to Ava Trade Japan K.K. in the JFSA register, which is why AvaTrade is the only brand in our database with a Japanese entry.

Also check whether the dealer is a member of the Financial Futures Association of Japan (FFAJ), the self-regulatory body for firms handling FX and other financial futures. The FFAJ writes conduct rules and publishes guidance on the margin rules. It also handles consultations on disputes with member firms and passes mediation to FINMAC.

Worked example: an app shows a Japanese-language site, JPY accounts and a "regulated" badge, but the footer names a company in Seychelles. That company can be licensed at home and still not be allowed to solicit you in Japan.

Common mistake: assuming that a Japanese-language site, Japanese support staff or a large number of Japanese users means the firm is permitted to serve Japan.

Tip: search the register for the exact company name in the agreement, in both full-width and half-width characters, as the JFSA itself advises for Latin-alphabet names.

How to check a firm in the JFSA register and the warning list#

Use two official JFSA lists, one positive and one negative. You need a match on the first and no match on the second.

1. The register. The JFSA page "List of licensed (registered) financial institutions" links to the Financial Instruments Business Operators register as a PDF and Excel file. The version we checked holds data as at 31 August 2026. Look for the company, its registration number, the Local Finance Bureau and a mark in the Type I column.
2. The warning list. The JFSA page "Names of unregistered firms conducting financial instruments business" lists firms that received a warning letter from the JFSA or a Local Finance Bureau since January 2010. There are separate files for domestic and overseas firms plus a combined HTML version, last updated 25 September 2026.

The JFSA adds two caveats. A firm missing from the warning list may still be operating without registration, and each entry reflects the situation when the letter was sent.

Worked example: you copy "Ava Trade Japan K.K." from an agreement and find アヴァトレード・ジャパン株式会社 in the register with No. 1662 and a Type I mark. The phone number and address in that row match the website, so the entity check passes. Costs and suitability are still your call.

Common mistake: treating "not on the warning list" as proof of legitimacy. Only the register confirms permission.

Tip: save a dated copy of both results. If a dispute arises later, it helps to show what the firm's status was on the day you opened the account.

What the JFSA warning list says about XM and Exness names#

Readers often ask about these two brands, so here is exactly what the JFSA published, checked on 28 September 2026 against the HTML list updated 25 September 2026. The entries are in Japanese; the dates below are converted from the Japanese era calendar.

Every entry concerns OTC derivative trading offered over the internet without Japanese registration. We did not find Trading Point, Tradexfin, Nymstar, XM or Exness in the JFSA register of Financial Instruments Business Operators (data as at 31 August 2026).

Keep the limits in view. A JFSA warning is an administrative notice about unregistered business with Japan residents. It is not a finding of fraud, and it says nothing about how these groups are supervised in Cyprus, Dubai or South Africa. The 2024 "XM WebTrader" entry names no operator; the JFSA only notes the name resembles XMTrading. For a Japan resident, the practical point is that none of these entities offers the Japanese protections described below.

Common mistake: reading a group's CySEC or FSCA licence as covering Japan. Licences attach to specific companies and specific countries.

The 25x rule and other protections for individual traders#

For individuals trading OTC FX with a registered dealer, the answer is simple: at least 4% margin on every currency pair, which means 25x leverage or less. The FFAJ explains that the rule came in stages. A 2% minimum applied from 1 August 2010, and the 4% minimum has applied since 1 August 2011. Since February 2017 corporate accounts have faced separate pair-by-pair margin rates calculated from past market moves.

The margin rule sits inside a wider package that the JFSA summarises on its FX page:

• Trust-held margin. Since 1 February 2010, dealers must hold client margin in a money trust with a trust bank, separate from the firm's own assets.
• Loss-cut rule. Dealers must set and follow a rule that force-closes positions when losses reach a pre-agreed level. The JFSA warns that losses can still exceed deposited margin in fast markets.
• Solicitation limits. Unsolicited visits or calls to sell OTC FX are banned, as is soliciting offsetting buy and sell positions in the same pair.
• Risk disclosures. OTC FX dealers publish their uncovered position ratio, their cover counterparties' credit ratings and their average client margin ratio.

Crypto-asset derivatives follow a stricter cap. Since the FIEA amendments took effect in May 2020, offering them requires Type I registration, and the JFSA set the leverage limit for individuals at 2x regardless of the coin.

Worked example: you buy 10,000 USD/JPY at an illustrative 150.00. The position is worth ¥1,500,000, so a registered dealer must hold at least ¥60,000 (4%) as margin. An offshore account at 500x would ask for about ¥3,000. The market risk is identical; only the cash cushion before a loss-cut differs.

Common mistake: believing 25x is a safe amount of leverage. At 25x, a 4% move against you wipes out the minimum margin. Our comparison of retail leverage limits puts Japan's cap next to the ESMA, FCA and ASIC rules.

Tip: open the dealer's published uncovered ratio and cover-counterparty table before you compare spreads. It shows how the firm manages the risk you hand to it.

Registered dealer, exchange FX or overseas firm: how the routes compare#

Japan residents effectively choose between three routes. The first two sit inside Japanese regulation; the third does not.

How the NTA taxes FX gains, and why the broker route matters#

Japan's National Tax Agency ties the tax treatment to who your counterparty is. According to Tax Answer No.1521, FX qualifies for separate self-assessment taxation (申告分離課税) when it is exchange-traded, or when it is OTC FX with a Type I Financial Instruments Business Operator or a registered financial institution. Qualifying gains are taxed at 15% national income tax plus 5% local inhabitant tax. On top of that comes the special reconstruction income tax, 2.1% of the income tax, which brings the combined rate to about 20.315%.

Qualifying losses can be offset against other income in the same futures-type category. Under conditions, any unused loss can be carried forward for the next three years. The NTA also notes a change for income arising from 1 January 2027: the reconstruction surtax falls to 1.1% and a new 1% defence special income tax is added. Check the NTA for the combined figure when you file for 2027.

For FX that is neither exchange-traded nor OTC with such an operator, the NTA says gains are generally miscellaneous income under comprehensive taxation. That means progressive rates applied to your total taxable income. Losses on those trades cannot be offset against the separately taxed category.

Worked example: a net gain of ¥500,000 with a registered dealer means about ¥101,575 of combined tax at 20.315%, before other factors in your return. As miscellaneous income, the same gain would be added to your salary and taxed at your marginal rates, which for a higher earner can cost noticeably more.

Common mistake: assuming the 20.315% rate applies to any FX account. The NTA's wording turns on the counterparty's registration.

Tip: keep annual trade reports, deposit and withdrawal records and JPY conversion evidence. Confirm your filing position with a licensed tax accountant (zeirishi) if the amounts are material. Our country tax comparison shows how Japan's approach compares with other countries.

Yen, the Bank of Japan and intervention risk#

The yen (JPY) floats freely; Japan moved to a floating exchange rate in February 1973. The Bank of Japan sets monetary policy, but intervention works differently. Under the Foreign Exchange and Foreign Trade Act, the Minister of Finance decides whether to intervene, and the Bank of Japan carries out the trades as the Minister's agent. The Ministry of Finance publishes intervention amounts monthly and quarterly.

Intervention and surprise BOJ decisions can move USD/JPY sharply within minutes, which is when loss-cuts, gaps and trust-held margin stop being abstract. For background, read our explainers on central bank FX intervention and on why the yen has been weak.

Common mistake: trading through an intervention headline with a position sized for normal volatility.

Trading hours from Tokyo#

Japan Standard Time is UTC+9 all year, with no daylight saving. The clock shifts you feel come from London and New York. London's 08:00 open falls at 16:00 JST during UK summer time and at 17:00 JST in winter. US data released at 08:30 New York time lands at 21:30 JST in US summer time and at 22:30 JST in winter. The weekly market reopens on Monday morning in Tokyo, around the Sydney and Wellington open.

The UK and US change clocks on different dates, so for a week or two each spring and autumn the gap shifts. Check our forex market hours tool and the Asian session guide.

Tip: on a normal Tokyo working day, major US releases arrive late in the evening. Decide in advance whether you will be flat, protected by a stop, or awake.

Notes for Arab and Muslim traders living in Japan#

If you live in Japan, you are treated as a Japan resident for these rules whatever your nationality. Expect a registered dealer to verify your Japanese address and identity during onboarding, and check with the dealer whether it needs your My Number (individual number) for tax reporting. If you are only visiting, or you live elsewhere, your home country's rules apply instead.

Swap-free (Islamic) accounts are marketed mainly by international groups, and we found no official Japanese source that addresses them. Ask a registered dealer directly whether it offers one. A swap-free label is a fee structure, not a religious ruling, and scholars differ on whether leveraged trading is permissible at all.
