You open Uma Musume: Pretty Derby and try to start the game, but the age confirmation screen won’t move. The OK button doesn’t work, or the date box refuses to accept input. It’s frustrating when you just want to race your horses, but this issue is actually quite common. Don’t worry, it’s usually caused by a simple setting or input mistake. Here’s what the Age Confirmation means, why it freezes, and how to fix it fast on PC, Android, or iOS.

What Is the Age Confirmation in Uma Musume?

What Is the Age Confirmation in Uma Musume

Before you can start playing, Cygames requires players to confirm their birth month and year. This system ensures compliance with local age-rating laws and parental control policies. You’ll see a box asking you to enter your birth date in numeric format, for example, 199510 for October 1995.

This step is one-time only. Once you confirm your age, you can’t change it again. It appears for new players, after reinstalling the game, or when switching devices. The game needs this information to determine if certain features or events should be restricted.

Common Causes of the Age Confirmation Not Working in Uma Musume

This problem usually comes from a minor glitch or incorrect input format. Here are the main reasons:

  • You entered your date in the wrong order, like MMYYYY instead of YYYYMM.
  • Your phone or PC is set to a non-Japanese region or language.
  • Cached game data or cookies are corrupted.
  • You’re using an old version of the game or browser (for DMM players).
  • An emulator or overlay app blocks the OK button.
  • Poor or unstable internet connection.
  • Temporary Cygames server issues during updates.

How to Fix “Age Confirmation Not Working” in Uma Musume?

Here are the most reliable fixes that get players back into the game. Try them in order until the OK button works again.

Fix #1: Enter the Date in the Correct Format (YYYYMM)

This is the most common mistake. The game only accepts six digits, year first, then month. For example, type 199510 (for October 1995) instead of 101995 or 10/1995.
Once entered correctly, the OK button should turn green and become clickable.

Fix #2: Switch Your Device’s Region to Japan

Uma Musume was originally released for the Japanese market, so region mismatch can cause the form to reject input.
Follow these steps:

  1. Open your phone or PC language and region settings.
  2. Change your region to Japan (日本).
  3. Restart the game and re-enter your birth year and month.
    After confirming, you can switch the region back to normal.

Fix #3: Clear Game Cache and Restart

Old cache can interfere with how the age form loads.

  • Android: Go to Settings → Apps → Uma Musume → Storage → Clear Cache.
  • iOS: Reinstall the app (iOS doesn’t allow manual cache clearing).
  • PC/DMM: Clear browser cache and cookies, then reopen the game page.
    After that, relaunch Uma Musume and try again.

Fix #4: Update the Game or Browser

If you’re using an older version, UI bugs can block input recognition. Updating ensures full compatibility.

  • On mobile, open the App Store or Google Play, search for Uma Musume, and tap Update.
  • On PC, update your browser or the DMM client to the newest build.

Fix #5: Restart Your Device or Emulator

Memory conflicts sometimes stop the OK button from responding. Restarting clears temporary data and resets your input focus. Close Uma Musume completely, restart your device, then launch the game again.

Fix #6: Disable Overlays or Floating Apps

Screen filters, recorders, or floating chat heads can block touch detection.
Turn off blue light filters, screen recorders, or any apps running above the game. Once disabled, the OK button should respond normally.

Fix #7: Reinstall Uma Musume

If the game’s local files are corrupted, reinstalling will give you a clean copy.
Uninstall Uma Musume, restart your device, then download it again from the official App Store, Google Play, or DMM Games site.

Fix #8: Change Keyboard Input Type

Some custom keyboards add spaces or symbols that the form doesn’t accept. Switch to a basic English or Japanese numeric keyboard and type your date again.

Fix #9: Check for Maintenance or Server Delay

Sometimes, the game itself is in maintenance. When Cygames updates servers, input forms may not respond.
Check Uma Musume’s official X (Twitter) or the DMM news page for maintenance notices. If that’s the case, just wait a few hours.

Prevention Tips to Avoid Age Error in Uma Musume

After fixing the issue, here’s how to prevent it from happening again:

  • Always use the correct YYYYMM date format.
  • Keep your game updated.
  • Avoid changing system region mid-session.
  • Don’t use overlay or macro tools.
  • Use stable Wi-Fi or mobile data.
  • Clear cache regularly if playing on PC.
  • Install only from official sources.

Conclusion

If the Uma Musume age confirmation screen isn’t working, it’s usually a small issue, like wrong input format or region mismatch. Once you enter your date as YYYYMM and ensure your app or browser is up to date, the OK button should activate immediately.

If none of these fixes help, contact Cygames Support through the game’s help section or DMM customer service. They can reset your verification or guide you through the process. After that, you’ll be back on track to train your horses and enjoy the races without interruption.
