Ryukyu-inu a.k.a. Ryukyu-ken is a rare breed of dog endemic to Okinawa. My friend Roy who owns Musashi said he had to have an interview before he could get a Ryukyu-inu. Roy had to agree to numerous conditions including not neutering the dog and allowing it to be used for stud if needed. Very much on the wolf end of the domestic dog spectrum, it’s an impressive animal.
