Kohaku is a cream yellow Shiba Inu dog with white paws and his inner ears and spots above his eyes are colored light brown. His Jewel Eyes are made out of orange and brown ambers. For his attire, he wears a red bandana pinned with an orange flower-shaped jewel around his neck.
Kohaku's Jewel Charm is oval-shaped. In the center is an orange amber gem shaped like a sun. It also has red and amber-colored decor and Kohaku's trademark red bandana at the top.
Kohaku is usually portrayed as a bit clumsy and sensitive, but is overall very supportive to his friends.
As the Jewelpet of Leadership, Kohaku's power can make humans able to guide a group and set direction for their people to do tasks. Also being the Jewelpet of Economic Fortune, his magic spells can increase a human's luck and chances of winning big prizes. In Jewelpet, Kohaku wields the power of the latter, while in Jewelpet Twinkle☆ he has the former.
Kohaku is a member of the Decoranain's Shitennou, working alongside Tour. His tactic is to trick people with his cuteness and turn them against each other, as demonstrated in episode 44. In episode 48, he and Tour are transformed back into their Jewel Charm forms by Retsu after he is corrupted by Kaiser. For unknown reasons, they were never seen again.

- Kohaku's jewel motif is the amber, a fossilized tree resin which has been appreciated for its color and natural beauty since Neolithic times. Amber is used as an ingredient in perfumes, a healing agent in folk medicine, and jewelry.
