For course items, you also translate the same as the course translation.
Please go to Dashboard => LearnPress => Lessons => Click to “Add translation to Japanese”.
The site will open the translating tab.
When the process is 100% complete, you need to click “Save & Close” to finish and review.
After selecting “Save & Close”, the site will return to the Lessons page. In the Backend, you can see the lesson you have just translated.
