Chokyūkai

was a demon from the continent (China) who used human girls as brides, including Kagome Higurashi. He gets girls to be his bride by placing a golden diadem on their head. His servants are Son Goku and Sha Gojyo.

Manga VS Anime
Chokyūkai is an anime-exclusive character, so his encounter in Season 6 with Hakudōshi and Entei did not transpire in the manga. However, in the manga, Hakudōshi acquires his naginata after Entei tramples a boar demon identical to Chokyūkai (after that this boar killed a human).

Chokyūkai's naginata is also identical to the one that Hakudōshi took from the boar demon. In the anime, Hakudōshi obtains it after killing Rengokuki and it is colored slightly different.

So the physical appearance of Chokyukai is based on that of this demon boar.

Trivia

 * He is very similar to Miroku in his pursuit of women, asking them to bear his child
 * The name 'Chokyukai' is almost same as his grandfather's name called 'Cho Hakkai', who originates from a Chinese fairy tale named 'A Journey to the West'.
