佐々木健介
Rotunda jumped to New Japan Pro-Wrestling in the summer of 1997 (as Michael Wallstreet), where he joined nWo Japan. He toured full-time with New Japan, and was used in the midcard. Like many gaijin, he wasn't used at Dome Shows and was left off New Japan's top tournaments such as the G1 Climax and the Super Grade Tag League tournaments. Wallstreet did participate in two other tournaments. In May 1998, he teamed with Big Titan in a tournament for the vacant IWGP Tag Team Championship, losing in the first round to Kensuke Sasaki and Kazuo Yamazaki. In September 1998, he teamed with Scott Norton in a tournament to decide the #1 contenders for the WCW World Tag Team Championship. They made it to the semifinals, where they lost to eventual tournament winners Kensuke Sasaki and Yuji Nagata.
