Hey, we do have Japanese as the language. You can change the language settings within the app to use it in Japanese. If you need help with how to change the language settings, please reach out to us at support@thestempedia.com
Thank you for your feedback! The 3D XR feature in the Google Play Store version of PictoBlox is not yet implemented, but our team is working on it. We also appreciate your suggestion for Japanese language support and will consider it for future updates. Stay tuned for updates! :)
