Z-kai My Z Portal: Your Guardian's Digital Learning Hub

Quick Summary

  • my Z is Z-kai's current parent portal
  • Manage learning, accounts, and support
  • Z-ID and guardian number required

Z-kai My Page (Z会マイページ) was the previous dedicated online platform for Z-kai members, serving as a digital portal for students and parents to manage learning and account details. However, to enhance the online account management experience for guardians, Z-kai introduced my Z (マイゼット) at the end of 2024. This new online hub is designed specifically for parents and guardians, offering comprehensive tools to support their children's educational journey. The original Z-kai My Page transitioned out of service by March 2026, making my Z the primary digital interface for many Z-kai courses today.

What You Need to Connect to Your Z-kai Online Hub

Navigating Your Digital Portal for Z-kai Learning

  1. Navigate to the official my Z login page at https://www.zkai.co.jp/home/mypage/myz_login/.
  2. Enter your Z-ID and the password you have set.
  3. If it's your first time or you need to link your account, you will typically need to complete a Z-ID registration process and link your Z-ID with your guardian number. This involves confirming your email and following the on-screen instructions.
  4. After successful login, you can select the specific academic year or course you wish to view or manage.

Monitoring Progress and Managing Your Child's Academic Journey

Regaining Access to Your Online Learning Account

⚠️ Forgotten Passwords

Cause: The user cannot recall their password.

Solution: We know being locked out is stressful. If you cannot recall your password, use the '会員パスワード/保護者パスワードを忘れた方' (Forgot Member Password/Guardian Password) link on the login screen to initiate a reset. You will need your registered email address to complete this process promptly.

⚠️ Incorrect Login Credentials

Cause: User is entering the wrong Z-ID or password.

Solution: Double-check that you are using the correct Z-ID and password. Remember that there are separate logins for students (member number) and guardians (guardian number starting with 'H'). The Z-kai Learning App for students requires a member number, not a guardian number.

⚠️ Z-ID Setup Issues

Cause: Difficulties during Z-ID registration or linking the guardian number.

Solution: If you encounter difficulties during the Z-ID registration or linking your guardian number, review the dedicated Z-ID setup guide or contact technical support for assistance.

⚠️ App Download or Compatibility Problems

Cause: Inability to download or use the Z-kai Learning App.

Solution: Ensure your device meets the specified operating environment requirements for the Z-kai Learning App. Verify your Apple ID account if using iOS devices, and check if new app downloads are restricted on your tablet.

⚠️ Page Not Displayed Errors

Cause: Encountering 'Page Not Displayed' messages.

Solution: This can occur due to high server traffic or network issues. Try accessing the portal again after a short while. If the problem persists, confirm your internet service provider settings.

Key Information for Z-kai Online Account Holders

Q: What is "my Z (マイゼット)"?

my Z is the updated online portal for Z-kai parents and guardians, launched at the end of 2024. It replaced the former Z-kai My Page and provides tools for managing your child's learning progress and account details.
