Can Japanese Users Use OKX? Is There a Dedicated Version?
Japanese users can use OKX, but must use the compliant version specifically launched for the Japanese market — the standalone site okj.com, not the global site okx.com. The global platform's terms of service explicitly list Japan as a restricted region. Japanese IP addresses and identification documents cannot complete registration or use on okx.com. In August 2025, OKX's Japan subsidiary (okj.com) obtained full regulatory approval from Japan's Financial Services Agency (FSA), officially becoming one of Japan's top three exchanges.

Core Differences Between the Two Versions
| Comparison Dimension | Global Platform (okx.com) | Japan Dedicated Version (okj.com) |
|---|---|---|
| Availability for Japanese Users | Not available, Japan is explicitly restricted in the terms of service | Available, operates with an FSA license in compliance |
| Regulatory License | No Japan FSA license | Has obtained full FSA regulatory approval |
| Account Opening Requirements | Japanese identity information cannot pass KYC | Accepts Japanese identity documents for verification |
| JPY Deposits/Withdrawals | Not supported | Supports domestic bank transfers and local payment methods |
Remember one principle: Users located in Japan who hold Japanese identification must only use okj.com. Attempting to register on okx.com will result in the system detecting the IP and identity information and blocking the attempt directly.
How Japanese Users Register the OKX Dedicated Version
1. Access the Correct Official Website
What to do: Visit the OKX Japan dedicated site, not the global site.
How to do it:
Enter the official URL okj.com in your browser.
Do not attempt to register on okx.com (you will be blocked).
When is it done: The page loads normally and you can see the Japanese interface and the "新規登録" (Register) button.
The Japan dedicated domain is okj.com. Make sure to use this address to avoid fake or phishing websites.
2. Click "Register" and Fill in Registration Information
What to do: Enter the registration page and choose a registration method.
How to do it:
Click the "新規登録" button in the upper right corner of the page.
Registration supports email or Japanese phone number (+81).
After entering the information, click "確認コードを取得" (Get Verification Code).
Enter the verification code you receive.
When is it done: The verification code is confirmed and you proceed to the password setting page.
3. Set a Login Password
What to do: Set a secure password for your account.
How to do it:
Password must be 8-20 characters, including letters, numbers, and special characters.
Confirm the password and submit.
When is it done: The system prompts that the password has been set successfully.
4. Select Country/Region of Residence
What to do: Select your residence during the registration process.
How to do it:
Select "Japan" from the dropdown list.
The system will confirm you are using the compliant Japanese version.
When is it done: You enter the KYC identity verification stage.
5. Complete Identity Verification (KYC)
What to do: Submit a government-issued Japanese identification document. This is a mandatory requirement under FSA regulations.
How to do it:
Log in and go to the "本人確認" (Identity Verification) page.
Case A - Using a Japanese driver's license (運転免許証):
Fill in your name (matching the license) and driver's license number.
Upload photos of the front and back of the license (ensure they are clear and free of glare).
Complete facial recognition.
Case B - Using a My Number card (マイナンバーカード) or passport:
Fill in your name and document number.
Upload a photo of the document.
Complete facial recognition.
When is it done: The system displays "Submission Successful" and enters the review status. The review is usually completed within 1-3 business days, and the result will be notified by email.
Common reasons for failure:
The document photo is blurry, has glare, or information is obscured.
The name entered (Japanese kanji/English spelling) does not match the document.
The document has expired.
Risk reminder: Japan's FSA has extremely strict Anti-Money Laundering (AML) and KYC requirements. Registering with false identity information will result in immediate account freezing, possible reporting to the Financial Services Agency, and potential legal consequences.
6. Enable Two-Factor Authentication (2FA)
What to do: Add a second layer of security to your account.
How to do it:
Go to "設定" (Settings) → "セキュリティ" (Security Center).

What to Do Next After Registration
After confirming that KYC verification has passed, Japanese users can deposit and withdraw funds via domestic bank transfers (such as MUFG, SMBC, etc.) or payment methods supporting Japanese Yen (JPY). Please refer to the real-time display on the okj.com "入金" (Deposit) page for specific available channels.
Review waiting time: KYC review is usually completed within 1-3 business days. If you have not received a result after this time, contact OKX Japan customer service through the in-app live chat or email. The Japan dedicated site has a Japanese-speaking customer support team.
