Japanese Striking Sensation Tenshin Nasukawa Obliterated an Argentinian Opponent to Win the ISKA Featherweight Title… He Adds Yet Another Scalp to His Unbeaten Kickboxing Record… 

Tenshin Nasukawa might be most famous to western combat sports fans for his humiliating loss to Floyd Mayweather. However, make no mistake, the 20-year-old from Chiba, Japan is a sensational talent, especially when it comes to taking on opponents who are actually the same size as him.

He first rose to fame in 2016 when he defeated IBF boxing world champion Amnat Ruenroeng and Lumpinee Stadium Muay Thai champion Wanchalong PK Senchaigym by knockout. Those guys are legitimately talented fighters. His unbeaten record of 31-0 is definitely not full of no-namers.

Now he’s added the ISKA featherweight title to his list of honours by beating Argentina’s Martin Blanco. Check out the footage below of Tenshin as he goes to work on the body of his hapless opponent. The boy is in a different class.


Nasukawa fought Martin Blanco in the main event of RIZIN 16 for the vacant ISKA featherweight championship. ISKA is one of the major karate and kickboxing governing bodies in the world and is based out of the US. This was a dominant display by the Japanese fighter against his Argentinian opponent.

He put on a typical striking clinic. In the clip above you can see how he caught Blanco with a sharp overhand left, before catching him viciously in the body with a brutal kick to the organs, dropping the Argentina native to the floor. He was able to get back up but was clearly compromised. Nasukawa sensed the finish and got it in style by pulverizing Blanco’s body with a heavy knee to the guts.

It was a superb display of savage efficiency by Tenshin, who is definitely one of the most exciting fighters operating out of Asia right now. You can bet that ONE Championship would love to get their hands on him.


In the co-main event, RIZIN atomweight champion Ayaka Hamasaki took on Invicta’s Jinh Yu Frey in a cross-promotion champion v champion fight. It’s the second time RIZIN has collaborated with a major US promotion, after Bellator’s bantamweight king Darrion Caldwell fought the Japanese organization’s champion, Kyoji Horiguchi.

Both times RIZIN have come off victorious. Hamasaki walked away with a unanimous decision victory. This is the second time she’s beaten Frey and can now call herself one of the best female fighters on the planet.
