Japan’s New KYC Rules and the Self-Custody Backup Plan
Since 2023, Japan’s Financial Services Agency (FSA) has continued to tighten KYC obligations for crypto asset exchanges, including implementing the FATF Travel Rule across most virtual asset service providers (VASPs). For users who have long relied on centralized exchanges, stricter regulation can mean more identity checks, more withdrawal friction, and in some cases account restrictions or freezes.
That is why self-custody wallets are becoming a practical fallback for more users in Japan. OneKey Wallet offers a non-custodial setup designed for users who want to keep control of their own keys while still accessing DeFi and perpetuals through OneKey Perps.
How Japan’s crypto KYC rules have evolved
The FSA regulatory framework
Japan regulates crypto assets under both the Payment Services Act (PSA) and the Financial Instruments and Exchange Act (FIEA). The FSA requires licensed exchanges operating in Japan to perform strict customer identity verification.
In 2023, Japan incorporated the FATF Travel Rule into local rules. Transfers above JPY 30,000, roughly USD 200, must include identifying information for both the sender and the recipient.
Key impacts for users
- Licensed exchanges in Japan, such as bitFlyer, Coincheck, and GMO Coin, require users to submit identity documents such as a passport or driver’s license.
- Withdrawals to unknown addresses may face additional review, with delays ranging from hours to days.
- Trading records are increasingly tied to tax reporting, and the FSA can require platforms to disclose user data.
- Some offshore exchanges have exited the Japanese market or restricted access from Japanese IP addresses.
The knock-on effect of the Travel Rule
The FATF Travel Rule requires VASPs to transmit sender name, account number, and recipient information for transfers above the applicable threshold. In practice, this creates two common problems.
First, when a user withdraws to a self-custody address, the exchange may not be able to verify the identity of the receiving party in the same way it can with another VASP. Second, some platforms respond by restricting or refusing withdrawals to external addresses that are not pre-approved or whitelisted.
The result is that users may feel pushed to keep assets on centralized platforms for longer than they want. That runs against one of crypto’s core principles: the ability to hold and move assets without relying on an intermediary.
Why self-custody is becoming the fallback option
Non-custodial wallets are not subject to exchange-style KYC
Under Japan’s current framework, a self-custody wallet itself is not a VASP. Wallet software providers are not required to collect exchange-style KYC simply because a user creates or controls a wallet address.
Once you withdraw assets from an exchange to an address controlled by your own wallet, your later on-chain activity is not automatically tied to mandatory identity collection by a custodial platform.
Self-custody does not mean anonymity. Blockchains are public, and transaction history can be analyzed. But from a custody and compliance perspective, it gives users more direct control over their assets and fewer platform-level dependencies.
The real risks of self-custody
Self-custody also shifts responsibility to the user. If your recovery phrase is lost or exposed, your assets may be unrecoverable. Malicious approvals, phishing sites, fake wallet apps, and wallet drainers are real threats.
That makes wallet selection and operational security critical. A good self-custody setup should prioritize open-source software, hardware wallet support, clear transaction signing, and safe recovery phrase handling.

How to move from a Japanese exchange to OneKey
- Download OneKey App from the official source and connect a OneKey hardware wallet if you have one. Hardware signing is optional, but recommended.
- Create a new wallet and write down the recovery phrase offline. Do not take screenshots or store it in cloud notes.
- Start a withdrawal from your exchange to your OneKey address. The platform may require extra verification or address whitelisting.
- After the assets arrive, you can use OneKey’s built-in WalletConnect support to access DeFi protocols and perpetual DEXs.
- If you want to continue trading perpetuals, you can use OneKey Perps to connect to Hyperliquid without additional KYC.
What this means for perpetual traders
Active perps traders often worry that self-custody will slow them down. It does not have to.
Hyperliquid is an on-chain order book perpetual DEX where users sign with their wallet instead of logging in through a centralized exchange account. The workflow is non-custodial: your private keys remain on your local device and do not touch an exchange server.
Through OneKey Perps, users can trade dozens of perpetual markets on Hyperliquid while keeping custody of their assets. This setup is especially relevant for users who want to reduce centralized exchange dependency without giving up access to active trading tools.
FAQ
Q1: Will Japanese regulators directly regulate self-custody wallets?
As of the time of writing, Japan’s KYC obligations apply to VASPs such as licensed exchanges and brokers, not to personal self-custody wallet software used by individuals. Regulations can change, so users should monitor official FSA announcements and consult local tax or legal professionals where necessary.
Q2: Will a Japanese exchange question withdrawals to a self-custody address?
It may. Some platforms ask users to confirm address ownership or complete a whitelisting process. Others may add a waiting period before withdrawal. These are internal compliance controls by the platform and do not mean that self-custody itself is illegal.
Q3: Where can OneKey’s open-source code be reviewed?
OneKey’s firmware and app are open source, and the code is hosted on GitHub for public review and audit.
Q4: Does the Travel Rule extend to on-chain tracking?
The Travel Rule currently governs information-sharing obligations between VASPs. It does not impose tracking rules directly at the protocol layer. However, blockchain analytics companies such as Chainalysis do provide on-chain tracing tools to regulators and compliance teams. Stronger on-chain privacy may require mixers or privacy protocols, but these tools can carry additional legal risk in Japan.
Q5: Does OneKey Perps support direct JPY deposits and withdrawals?
OneKey Perps is settled on-chain in USDC and does not currently support direct fiat deposits. Users generally need to convert JPY into a supported stablecoin through a licensed exchange, withdraw to OneKey, and then connect to Hyperliquid through OneKey Perps.
Conclusion and practical next steps
Japan’s stricter crypto KYC rules are part of a broader global trend, not an isolated event. For users who want to stay within the regulatory environment while keeping more control over their assets, moving holdings to OneKey Wallet and using OneKey Perps for decentralized perpetual trading is a practical path.
Download OneKey, set up your self-custody wallet carefully, and use OneKey Perps when you need non-custodial access to perpetual markets.
Risk warning: This article is for informational purposes only and is not financial, tax, or legal advice. Crypto assets are highly risky and can be extremely volatile. You may lose all of your principal. With self-custody, wallet security is your responsibility. Understand the relevant rules before acting, and consult a qualified professional where needed.
