Regulation & Client ProtectionJapan FSAFinancial Services Agency
FSA Japan
Japan's Financial Services Agency, which enforces a 1:25 retail forex leverage cap and mandatory trust segregation.
What FSA Japan means
The Financial Services Agency is Japan's integrated financial regulator, supervising banks, insurers and securities firms and administering the Financial Instruments and Exchange Act. A firm offering margin forex to Japanese retail clients must register as a Type I Financial Instruments Business Operator and belong to a self-regulatory body such as the Financial Futures Association of Japan. Japan is the largest retail forex market in the world by volume, and its rulebook is correspondingly detailed, prescriptive and strictly enforced through on-site inspections and business improvement orders.
Retail leverage on currency margin trading is capped at 1:25, among the strictest limits anywhere and unchanged despite repeated industry lobbying. Customer money must be placed in trust with a licensed trust bank under a separate trust agreement, reconciled daily and verified by an external auditor, so client funds are legally insulated from the operator's own estate. Firms must also operate mandatory loss-cut rules that close positions automatically at defined margin levels, publish execution and slippage policies, and meet capital adequacy ratio thresholds monitored by the FSA.
Trust segregation is a strong protection against operator insolvency but it is not compensation for trading losses, and it does not guarantee the timing or completeness of a return if reconciliation was defective. Japan's Investor Protection Fund covers securities business rather than over-the-counter forex margin balances, so the trust structure is the primary safeguard. The 1:25 cap limits position size but not the possibility of losing the full deposit, and clients who trade with unregistered offshore firms offering far higher leverage fall outside every one of these rules.
Worked example
A Japanese client with 500,000 JPY in a registered account can hold at most about 12.5 million JPY of currency exposure, and that cash sits in trust at a separate trust bank rather than on the broker's own balance sheet.

Trade with a regulated broker
Understanding the terminology is the cheap part. The expensive part is choosing a counterparty whose execution, financing and withdrawal behaviour match what the marketing implies. Every broker below has been reviewed with a funded live account, and each review states which legal entity and which regulator applies to the account you would actually open.
