Teppei Koike is an actor and singer from Japan. He was born in Osakasayama, Osaka Prefecture. He belongs to the production company Burning Productions and is a member of the singer-songwriter duo WaT with his partner, Eiji Wentz.
His immediate family consists of his father, mother, and a younger brother.
The name "Teppei" came from his father's favourite manga, Ore wa Teppei.
His cousin, Kyomoto Taiga, is a member of Johnny's Junior.EIJI WENTZ
He is really good friends with Eiji Wentz. They often visit each others houses, watch movies and go out to eat together. When they were doing street lives, they often borrowed each others clothes.
Teppei calls Wentz "Ei-chan".
They have spent Christmas together ever since they met. (The first year, they took purikura in Shinjuku; the second year, they ran a marathon for their indies debut PV; the third year, they ate at a hamburger shop; the fourth year was a WaT event and love*com photoshoot)
For Wentz's 20th birthday, Teppei bought him a lot of underwear. (Wentz has showed up on variety TV wearing just underwear a lot of times)
In "Bokura no Ibasho" (a manga based on Teppei's life story), Teppei said the only thing he had in common with Wentz was their love of music. Other than that, they are complete opposite. ("If we were in the same class or something, I definitely think we wouldn't be friends" - quote from "Bokura no Ibasho")
