Request for weblate usage in d-i Japanese translation

Dear d-i l10n coordinator,

I am trying to update ja translation for d-i, while the previous
translator kmuto is no longer active. He used to commit all the ja
translation things from himself and other translators.
Instead I would like to use weblate for possible reviews.
So I request for d-i weblate to enable Japanese:

Thanks in advance,
