Hello,
Thanks for reaching out to the Google Ads API support. Currently Ads API does not support Rakuten Mobile under the Mobile-carriers list.
I have raised a feature request for your concern (to add "Rakuten Mobile Japan" targeting option in the Mobile carrier) internally within our team on your behalf. Please note our team is unable to share any timeline information, and there is no guarantee the request will be approved.
I would suggest please keep an eye on our blog for further updates and announcements.
Best regards,
