Hello
I am Jun Nogata (nogajun) from the Japanese community.
I have requested it.

Please add a Sou Yanaihara and Jun Meguro Weblate Japanese reviewer role.

They are actively working on translation and would like to help us.

* Sou Yanaihara: https://translations.documentfoundation.org/user/So/
* Jun Meguro: https://translations.documentfoundation.org/user/parpy/

Regards,
Jun
