How to localize content on a Laravel site?

Question

Internationalization and localization

Good afternoon. Tell me, maybe someone came across.
There is a website in Lar - in Russian, we want to localize it, translate it into Japanese.
Subsequently, the translation will be in 5 other languages.
The question is how to make the localization of system moments understandable - this is easily done out of the box.
How to localize dynamic content is the question.
I heard there are JS - scripts that replace the text, depending on the locale.
But I'm not sure that this will have a good effect on the speed of the site.
Maybe there are ready-made libraries for the backend?
and how is it done in general? Manually translate all the text and upload it to the database and do the substitution depending on the locale?
And every time you add new material to the site - add it in 5 different languages? Is there a faster solution?
