Resolving Access Challenges within Your S-net Portal

⚠️ Forgot Password

Cause: The user cannot recall their S-net password.

Solution: We know being locked out is stressful. To regain access, simply click the 'パスワードを忘れた場合' (Forgot password) link located on the S-net login screen. Follow the on-screen instructions to reset your password. You'll need to enter the new password using half-width alphanumeric characters, 4-20 characters long.

⚠️ Unable to Log In

Cause: Incorrect Login ID or password entry.

Solution: First, ensure your Login ID is the correct 8-digit student ID. Then, double-check your password. Make sure you are using half-width alphanumeric characters and that caps lock is not accidentally enabled. Passwords are case-sensitive. If you've recently reset your password, ensure you're using the updated one. If problems persist, try the password reset option.

⚠️ Not Receiving Emails from S-net

Cause: Email address issues or spam filter settings.

Solution: Verify that the email address registered on your S-net account is current and correct. Crucially, adjust your email settings to allow reception from [email protected] and the entire sanaru-net.com domain. You may also need to permit 'spoofing' and 'URL attached' emails, as some notifications may be flagged by strict spam filters.

⚠️ Cannot Reply Directly to S-net Emails

Cause: S-net notification emails are system-generated and not designed for direct replies.

Solution: S-net's notification and attendance emails are automated. If you need to communicate with the school or a teacher, please log into the S-net portal and use the 'メッセージ' (Messaging) function. This ensures your message is delivered directly and securely to the appropriate staff member.

⚠️ Cannot Connect to S-net Login Screen

Cause: Incorrect URL or network issue.

Solution: Confirm that you are accessing the exact official URL: https://www.sana-net.jp/snet/. Pay close attention to the 'https' part, ensuring the 's' is included for secure access. If the URL is correct, check your internet connection or try accessing from a different browser or device.
