Yes, there are quite a few people riding Ducatis here. They have a pretty decent size group on Facebook. Most are old Japanese guys though as young people here cant afford a Ducati. Japan does bike licenses by engine size. 51-250cc / 251-400cc/ 401cc+ . So you have to pass a test for each one. But most just do the middle license and then buy a Honda/Yam 250cc for their first bike. One, because they are easy to ride, and two, 250cc and under dont have to do a bi-yearly inspection that cost around $300-$600.
