“Chai Tone W. Uracha,” a top star from the Petchyindee camp, boldly announced that at RWS 200 this Saturday, he will dismantle RISE world champion Koki Osaki just like he did with Koki flour.
On 26 June 2026, as the big historic RWS 200 boxing event approaches on Saturday, 27 June, one of the key highlights besides two superfights is the interim Rajadamnern super bantamweight 122-pound title bout between “Koki Osaki,” RISE world champion and ranked number 4 pound-for-pound globally in kickboxing rules, and “Chai Tone W. Uracha,” a leading talent from the Petchyindee camp.
This marks the third time RISE, Japan’s top boxing organization, has sent a world champion-level fighter to contest a Muay Thai title. The previous two attempts failed to overcome the Rajadamnern champions. This time, Koki carries great expectations to succeed and end RISE’s string of disappointments. He is especially motivated after witnessing his brother, Kazuki Osaki, lose decisively to Charoensuk Boonlanna in the R80 event marking Rajadamnern’s 80th anniversary late last year. Koki is fired up and confident he will not miss his chance this time.
“Ever since my brother lost, I have been determined that I am the one to end the organization's disappointment. This time I will knock out Chai Tone to become Rajadamnern champion—the greatest title in Muay Thai. If he thinks he can mix my blood into the flour, I believe he’ll fall before that can happen.”
For “Chai Tone,” this is the biggest fight of his life: a chance to challenge for the Rajadamnern title as a representative of Thai fighters facing one of the world's top opponents. He is confident he will keep the Rajadamnern belt in Thailand and intends to crush “Koki” just like mixing Koki flour.
“Koki flour has to be mixed with water, but I will mix it with his blood instead. This Saturday, I will knock him out. This is Thailand, not Japan. It won’t be an easy task for him. I won’t give him any chance.”
Both fighters have successfully made weight and are ready for the fight this Saturday. The winner by knockout will receive an immediate 850,000 baht bonus from RWS. Don’t miss the RWS 200 event—watch to see whether Koki or Chai Tone will become the interim champion in this division.
