Currently, the Orb of Origin displays the English text "Let's choose your origin(s)." as its description, but there is no corresponding translation key.
As a result, the above message appears in English regardless of the selected language.
If possible, I would greatly appreciate it if a translation key could be added to each language file to support localization.

In the latest 1.21 version it looks like the translation keys for the Orb of Origin are:

• "component.item.origins.origin.layer"
• "component.item.origins.origin.layer_and_origin"
• "component.item.origins.origin.generic"

The last key is only present in the English translation, so it defaults back to it in other languages. Hope this solves your problem!

I hadn't realized that translation keys might be added or changed between versions. Your comment really helped me notice that. Thank you very much. I'll update the Japanese translations for 1.21 accordingly.
