Japanese newspaper Sports Nippon then reported that Ishii would make his ring debut on December 31, 2009, at the annual K-1 Premium Dynamite!! event at the Saitama Super Arena. However, Ishii announced that he rejected FEG's offer, and was planning to pursue his MMA career in the US' Ultimate Fighting Championship (UFC). He headed to Florida where he trained with one of MMA's top camps American Top Team.[http://mmamania.com/2008/12/17/olympic-judo-gold-medalist-satoshi-ishi-headed-for-american-top-team/ Olympic Judo gold medalist Satoshi Ishi headed for American Top Team], MMA Mania, 17 December 2007

Ishii, who was a large favorite in the fight, was dominated in the first round by the more-experienced Yoshida, taking many strikes including a right overhand that staggered the newcomer, along with a series of knees and uppercuts from the clinch. Ishii, however, came back with a more competitive second round, but took a point deduction after illegally kneeing Yoshida in the groin. Ishii continued to find his range in the third round with punches, but ultimately lost via unanimous decision.{{cite web |title=石井弱かった 吉田に惨敗/Dynamite!! |url=https://www.nikkansports.com/battle/news/p-bt-tp0-20100101-581570.html |website=nikkansports.com |access-date=29 October 2021}}

In June 2010, Ishii caused controversy during an MMA exhibition match on the undercard of X-1 World Events: Nations Collide in Hawaii. After knocking down his opponent Myles Tynanes at the end of the first-round, Ishii failed to stop punching his downed foe despite the referee's attempts to halt the action. He was subsequently disqualified for his actions.{{cite web|url=http://www.sherdog.com/news/news/Ishii-Disqualified-in-X-1-Exhibition-Clay-Submits-Wolff-24877 |title=Ishii Disqualified in X-1 Exhibition; Clay Submits Wolff |date=June 5, 2010 |work=Sherdog.com |first=James |last=Meinhardt |access-date=June 5, 2010}}

Ishii was scheduled to make his North America debut for Strikeforce at Strikeforce Challengers 15 against Scott Lighty, but a visa issue stemming from the recent earthquake and tsunami left him unable to leave Japan.
