"I just talked to James and its official," Cheyenne (WY) East Head Coach Damon Artery said.
"He got back this afternoon and he went home and talked to his dad. Then he made the decision and called Wake Forest tonight."
Johnson traveled to Winston-Salem, NC., on Friday for an unofficial visit. During the weekend he hung out with the coaching staff, players and was able to watch a team scrimmag. He picked the Demon Deacons over Wyoming, Kansas, Maryland, Cincinnati and Bradley.
"He just said that he really liked it down there and he said it was great down there and he liked all the people. He's really excited."
While Johnson wasn't available for comment, Coach Artery think the Wake Forest coaching staff did a great job recruiting him and their conference played a big role as well.
"From talking to him I think that he really liked the coaching staff. He likes their conference. It's just a great setting and I think it will be good for James and I think he's excited about that."
Johnson, who is ranked 38th by Scout.com is an extremely versatile and athletic player for his size. His coming out party was at Nike Camp this year where he scored 16 points and grabbed 10 boards in the all-star game.
"He's extremely athletic and he shoots well and handles the ball pretty well," Johnson's high school coach said. "He can play a lot of different positions and I think that's what a lot of people like about him. He can handle it well and he can shoot it as well as play down low. He's just an outstanding competitor."
