[edit]Developmental territory (2007–2009)
In late 2007 Yamamoto was signed by World Wrestling Entertainment (WWE) to a full time contract, which meant that he had to relocate to the United States. He immediately was assigned to WWE's developmental territory Florida Championship Wrestling (FCW), to undergo assessment and training in the "WWE Style" of wrestling. Initially he wrestled as Mr. Yamamoto, then simply as Yamamoto.[16] He briefly teamed with Sheamus O'Shaunessy under the team name "the Movers and the Shakers".[17] Later on he changed his ring name to Yoshitatsu, before tweaking the spelling to Yoshi Tatsu, the name he currently works under.[16]
