Classic Yo-kai, Yo-kai Watch Wiki

Classic Yo-kai (Japanese: 古典妖怪, Koten Yōkai) are a group of Yo-kai hailing from decades or even centuries in the past; in other words, they have been around for a very long time. They first debuted in Yo-kai Watch 2. They are based on yōkai from traditional Japanese folklore, down to having the same name in Japanese in most cases. Originally, they could only be encountered in the past, be it in when searched with the Yo-kai Watch, in Yo-kai Spots, or in the Crank-a-kai from 60 years in the past.
