Career
Sawayashiki, at only 19 years old, turned pro in 2004 and started fighting for R.I.S.E. kickboxing promotion in Japan. He made his K-1 debut on December 2, 2006 at the K-1 WGP 2006 Final undercard, against Mitsugu Noda, winning the fight by split decision. On his next fight in Yokohama he stunned the K-1 world by a convincing victory over French kickboxing legend Jerome Le Banner.
After having his nose broken in the first round, Sawayashiki fought on and knocked down Fujimoto three times in the third round before referee stopped the fight. He suffered his first K-1 loss by first round Knockout after taking a tremendous right punch to the face. Sawayashiki's career went downhill from there, losing 4 more straight fights in a row, 3 KO losses to Musashi, Catalin Morosanu and Glaube Feitosa plus a punishing three round fight against Jerome Lebanner in the 2008 Final 16.
Many now consider Sawayashiki's career short lived and likely over.
