Yabuta officially signed with the Royals on November 28, 2007. He signed a two-year, $6 million deal with the Kansas City Royals. The deal included a $4 million club option for a third year. Yabuta was sent down to Triple-A Omaha Royals on June 25, 2008. He was designated for assignment on August 2 and was eventually sent outright to the minors. He was brought back to the Royals when the rosters expanded on September 1.

His teammates on the Royals have given him the nickname "Shake."

On November 24, 2009, he signed a one-year deal with his old team Chiba Lotte, and he has remained with the team since.
