We need to create ja_JP.csv in your custom theme: app/design/frontend/{Vendor Theme}/{Theme name}/i18n/ja_JP.csv

We can find the locale code by simple way:

You have to create ja_JP.csv file in your custom theme.


inside ja_JP.csv file first column is english name of text and other column name is japanese word.

example inside ja_JP.csv file.

"Add to compare","japanese word for add to compare set here"

Try this one I hope this helps.
