The more I go down the "Sonic in unpopular in Japan" rabbithole, the more "oof" it gets.
This is the most viewed video I found while YouTube searching Sonic's (full) Japanese name that isn't either English made with Japanese tags or Japanese made with an English localised title and description (the latter of which there was only one of for the full name, a little more showed up with just "Sonic", but still not much)
2.3 Million.
Oof.
