After that , I went to sellerdashboad → products → edit→ attributes page.
When I typed a word in ‘Option…’ in English ,the word was displayed in Product page.
However, when I typed a word in ‘Option…’in Japanese , the word was not displayed in Product page.
Dokan plugin is made over WooCommerce. In the backend the Japanese word is not showing which is coming from the system of WooCommerce. It is not handled by Dokan. So i will suggest you to contact with WooCommerce about this issue.
If the data was shown in the backend then we could do something. As the data is not showing in the backend so we are unable to help you.
It is not language problem, so I think other dokan users have same problem.
I typed the product detail and clicked ‘update product’.
However, on the next screen, there are not line break in the sentence I typed.
Incidentally, on the product page screen, there are line break properly.
For that reason, if I want to update the product detail again, do I have to start a new line again?
