Japanese dogs, known as Nihon-ken, refer to six native breeds (Akita, Shiba Inu, Shikoku, Kishu, Hokkaido, Kai Ken) recognized as national treasures, characterized by curled tails, prick ears, loyalty, bravery, and ancient hunting origins, making them popular companions but requiring experienced owners due to their independent, bold nature. They embody "samurai spirit," are excellent watchdogs, and have deep cultural roots in Japan, with the Shiba and Akita being the most famous globally. #loved
