The two-weight world champion has likely forgotten more about boxing than his upcoming opponent Tenshin Nasukawa will ever know about the sport.

The two headline in a scheduled 12-round bantamweight contest at Kokugikan, Tokyo, on April 11.

"It should be a really good fight and it's a fight with a lot of significance for us since it's an eliminator to be the mandatory to fight for the WBC bantamweight title against Takuma Inoue," Estrada (45-4, 28 KOs) told The Ring. "I'm very motivated and ready to do whatever it takes to get the win.

"I think he's gonna be a difficult opponent to face because of his style and quickness, since he's a southpaw. Plus, I think he'll give it his all to try to pull off a win in his home country."

Estrada, who has been a professional for 15 years longer than Nasukawa and has 41 more professional bouts than his rival, believes that will be the key to victory for him.

"I think he lacks experience in professional boxing, and I see that as a big advantage for me in my 49-fight career," he stated. "I'm ready to put on a great fight for Japan and the world to see."

However, it should be noted that the Mexican turns 36 three days after the fight and has been plagued by injuries throughout his career.

Has that taken something from him or has that allowed him to extend his prime? This fight will give us an idea of which of those is true.

"I have definitely had to deal with some injuries throughout my career, but thanks to God I've been able to overcome them," he said. "There's been times where I've had to fight with existing injuries, but you have to be able to deal with that and figure out a way to put on a good fight and pull off a victory."

"I think some of the injuries have affected my level of activity at times, but I try to maintain a good level of physical training and physical therapy to keep moving forward."

He looks at the injuries in two different ways.

"On one hand, I feel like I might have been able to win more titles and in general have more fights if I hadn't had the issues with my broken jaw and hand surgery," he said. "On the other hand, having long layoffs may turn out to be helpful in being able to have a longer career and training camps would've meant more wear and tear early on."

Estrada spent 18 months out of the ring prior to losing to Jesse Rodriguez (KO 7) in June 2024 and that was followed another 12 months on the sidelines.

He then resumed his career and jumped to bantamweight last June and beat Karim Arce (UD 10) to breathe new life into his career.

"I felt good and I felt strong fighting at 118 last time around," he noted. "I think moving up a division will be very beneficial for me and I'm looking forward to another big fight at bantamweight.

"I think not having to lose the extra pounds to make 115, combined with my experience, will result in another victory for me in this new division."

Estrada also decided he needed a new voice in the corner and is now working with German and Alfredo Leon as well as Orlando Plascencia and has held his camp at altitude in Mexico City.

Estrada is motivated to try to win another world title but first must get by Nasukawa.

"Thanks to God I have been fortunate to win world titles in two divisions, at 112 and 115pounds, and now that I move up to 118 that is my main objective, to win a world title in this new weight division, and this fight will be a great eliminator to face off against Takuma Inoue," he said.

"I'm ready to do whatever it takes to defeat Tenshin Nasukawa to move on and fight for the WBC bantamweight world title."

Nasukawa (7-1, 2 KOs) came to prominence after a standout MMA and kickboxing career. The soon to be 27-year-old engaged in an exhibition against boxing superstar Floyd Mayweather Jr. in 2018.

He reverted to boxing in April 2023. Since then, he has improved immeasurably and notably has wins over Jason Moloney (UD 10) and Victor Santillan (UD 10) but is coming off a loss when he fought Takuma Inoue (UD 12) for the vacant WBC title on November 24.
