Navigating Student Progress and School Communications

When S-net Access Isn't Working as Expected

⚠️ Cannot access the login screen or log in.

Cause: Incorrect URL, invalid Login ID, or incorrect password format.

Solution: First, verify the URL is exactly https://www.sana-net.jp/snet/, paying close attention to 'https'. Ensure your Login ID is the correct 8-digit student ID. Double-check your password for accuracy, making sure it uses alphanumeric, half-width characters. We know being locked out is stressful, so precise entry is key here.

⚠️ Forgot your S-net password.

Cause: Memory lapse or an outdated password.

Solution: If you've forgotten your password, navigate to the S-net login screen and click on the 「パスワードを忘れた場合 (Forgot Password)」 link. Follow the on-screen prompts to securely reset your password. This is the fastest way to regain access.

⚠️ Not receiving emails after registration or for notifications.

Cause: Incorrectly registered email address or strict spam filter settings.

Solution: Confirm that the email address registered on S-net is accurate. Importantly, adjust your email's spam or junk mail settings to allow messages from [email protected] and the entire sanaru-net.com domain. You may also need to permit 'spoofing' and 'URL-attached emails' to ensure all communications arrive.

⚠️ Cannot directly reply to notification emails.

Cause: Notification emails are system-generated and are for receiving information only.

Solution: System-generated emails, such as attendance or notification messages, are not designed for direct replies. If you need to communicate with the school or a teacher, please log into S-net and use the メッセージ機能 (Message function) to send a new message.

⚠️ Difficulty opening attached files on a smartphone.

Cause: Device-specific handling of file types or missing applications.

Solution: For iPhone users, after tapping the attachment link, choose 「表示 (Display)」 instead of download to view the file. For Android users, tap the link then 「開く (Open)」. If the file is a PDF and doesn't open, installing an application like Adobe Acrobat Reader might resolve the issue.
