I got some McDonald’s to go. On the paper bag, there was a picture of Ronald throwing trash in the trash can with an R mark next to it.
I looked it up on J-PlatPat and found that this illustration itself was trademarked. (Japanese Trademark Registration No. 5625449, Rights Holder: McDonald’s International Property Company Limited, Registered in 2013)
The first trademark for Ronald’s illustration was filed in 1980 and is still in effect (Japanese Trademark Registration No. 1677689). Multiple trademarks have been registered for Ronald alone, with different poses.
Incidentally, the original English name of this mascot is Ronald McDonald, so it would be pronounced “Ronald McDonald” in English. However, since “Ronald” is difficult for Japanese people to pronounce, “Donald McDonald” was adopted. Japan McDonald’s recognizes both ‘Donald’ and “Ronald” as correct names. (Marron)
