Should Japanese Users Choose Phone Number or Email for Binance Registration?
For Japanese users, it is recommended to prioritize email registration, followed by phone number. AlthoughBinancesupports both methods, email is generally the more hassle-free choice in terms of account security, cross-border usability, and message delivery reliability.

It is not an either-or decision—after registration, you can also bind the other method as a backup verification channel in the security settings.
1. Email Registration: Why It Is Preferred
Email registration offers several advantages over phone numbers in key areas:
More reliable verification code delivery: Major overseas email services like Gmail and Outlook rarely miss messages, making verification code reception during registration and login much more dependable than SMS. Some Japanese phone numbers or carriers may experience delays or blocking risks for international SMS.
Greater account portability: If you change your phone number in the future (e.g., switching carriers or leaving Japan), an email-registered account remains unaffected. With a phone number registration, changing numbers requires an extra step to update the binding.
Aligns with security best practices: Binance founder CZ has recommended using a separate email for trading platforms to isolate accounts and reduce cross-platform information leakage risks. For Japanese users, KYC typically involves passport verification, and the choice of registration email does not affect subsequent authentication.
2. Phone Number Registration: When It Is Acceptable
Phone number registration is also viable. It can be suitable if you meet the following conditions:
You do not plan to change your phone number in the near future, ensuring long-term stability
You prefer receiving SMS verification, finding it more convenient than email
You have confirmed that you can receive international SMS(some Japanese number ranges may work normally; it is advisable to test reception first)
When registering, Japanese users should selectJapanfrom the "Country/Region" dropdown list. The system will automatically match the international dialing code+81, so there is no need to manually enter the code when inputting your Japanese phone number.

3. Optimal Configuration After Registration
Regardless of which method you choose for registration, it is recommended to complete the following configurations immediately:
Bind the other method: If you registered with email, add your Japanese phone number in the security center; if you registered with phone number, add your email. Having both methods linked provides more verification channels and a backup option when changing numbers.
Enable two-factor authentication (2FA): Bind Google Authenticator or theBinanceAuthenticator in the security settings. This offers stronger protection than SMS or email alone. During setup, the system will generate a backup key—make sure to save it securely.
Complete KYC identity verification: Registration is only the first step; completing identity verification unlocks trading and deposit/withdrawal functions. Japanese users should select the Japan region during KYC and upload their documents as prompted.
