Japan is interesting. Maybe the Braun brand is still pretty strong over there. But in Europe and elsewhere you no longer see prominent "Braun" branding on the packaging - and it's been that way for a long time.
You're right that the Braun logo co-branding still features on the devices themselves, though.

It seems they have both names.
