[1] After graduating from Kansai University with a major in English,[2] he turned down a job at a television studio in order to practice martial arts full-time.

After defeating Patrick Smith and Adam Watt on the first day and Taiei Kin on the second, he met fellow karate superstar Andy Hug in the finals.

Nielsen placed his opponent on the defensive in the opening moments, but Satake fought back with repeated headbutts that led to a foul being ruled.

[3] Despite taking a two-year break from kickboxing afterwards to focus on karate, Satake followed his initial victory up with an undefeated streak that included draws against world champions Rob Kaman and Peter Aerts - establishing himself as a Japanese powerhouse who could hold his own against the best of international competition.

Based on his initial kickboxing record, his status as one of Japan's top karate competitors, and his affiliation with K-1 founder Kazuyoshi Ishii's Seidokaikan group, Satake was invited to participate in the first K-1 event - K-1 Sanctuary I.

He bested future Olympic bobsledder Todd Hays in the quarterfinals before suffering his first defeat (and knockout) to Branko Cikatić, who would go on to win the tournament.

After defeating karate champ Michael Thompson in the quarterfinals, he avenged his previous year's loss to Branko Cikatić with a decision victory over the Croatian Tiger.

Despite throwing no shortage of powerful strikes at the Dutchman, Satake was unable to land many significant blows while enduring several from Aerts, and lost by unanimous decision.

[10] He participated in the Mega Battle Tournament 1992, eliminating Mitsuya Nagai in the first round[11] but retiring prematurely due to an injury sustained in training.

At 34 years old, Satake was considered too old to perform adequately but sought to defy critics by joining the Takada Dojo, training under Kazushi Sakuraba.

Satake marked his opponent's leg with low kicks, but the judo champion managed to get Masaaki on the ground and submit him via rear naked choke in the second round.

Heavily outweighed, Satake was repeatedly driven against the ropes by his adversary, impeding him from landing solid strikes and resulting in an eventual unanimous decision loss.

The fight was immediately ruled a TKO win for Rampage while Satake was rushed to the hospital, where a cracked skull and a gravely injured neck were diagnosed.

[17] Satake's final fight was a bout against judo gold medalist Hidehiko Yoshida at Inoki Bom-Ba-Ye 2000, during which he fell to a guillotine choke.
