Yokoyama entered Johnny's on Christmas 1996 where he met fellow members Subaru Shibutani and Shingo Murakami. The reason he entered Johnny's is because his mother briefly saw his classmate on TV and said, "My kid is better looking." Rare among Johnny's talent, Yokoyama has been given a stage name. This has been said due to the difficult kanji of his real name, Kimitaka Yokoyama (横山 侯隆, Yokoyama Kimitaka). It is believed that "You" has been chosen by Johnny Kitagawa as it is easy to say. Although he has a stage name, nobody actually refers to him as "You", not even Johnny who is famous for referring to other people as "You".

When appearing in variety shows and radio, Yokoyama and Murakami are the two most talkative members. He has even been called a comedian due to his talking style. However, off screen, Yokoyama is very shy. He rarely speaks whilst in the dressing room, as he is too busy playing games.

Recently, Yokoyama has been appearing in quite a few dramas such as The Quiz Show 2 and Hidarime Tantei EYE.

Yokoyama's mother died at age 50 on May 16, 2010, at 11:51 pm. She collapsed while shopping, and was taken to the hospital in an ambulance. Sources say that it might have been a heart attack. The funeral was held on May 18, which all the members of Kanjani8 attended.^[2][3]
