Tenshin Nasukawa

Tenshin Nasukawa is a Japanese professional boxer and former kickboxer who rose from a dojo in Chiba to become one of the most decorated combat athletes in history. Born in 1998, he began training in karate at age five under his father before dominating the kickboxing world with an undefeated record of 40 wins.

By July 2022, Combat Press ranked him the top pound-for-pound fighter worldwide. He retired from kickboxing that same year to pursue professional boxing and mixed martial arts, where he continues to compete at the highest level. [edit]

Nasukawa was born into a family deeply rooted in martial arts in Matsudo, Chiba Prefecture. His father, Katsunori Nasukawa, was a karate instructor who founded the Ten-Shin dojo, which became the foundation for Tenshin's early development. The young Nasukawa started training in karate at just five years old, absorbing the discipline and techniques that would define his future style.

His natural talent became evident quickly. By age 12, he was already competing in amateur tournaments across Japan, accumulating a string of victories that drew attention from coaches and scouts. While attending high school, he faced a pivotal choice between academics and his burgeoning career. Driven by an intense desire to train full-time, he left school early to dedicate himself entirely to the ring. This decision marked the beginning of his professional journey, leading to his debut in 2012 and a meteoric rise through the ranks of Japanese kickboxing. [edit]

Nasukawa turned professional in kickboxing in 2012 and immediately began a streak of dominant performances. In 2014, he captured the RISE Bantamweight title, establishing himself as a force to be reckoned with in the lower weight classes. He continued his ascent, winning the prestigious RISE World Featherweight title in 2016 and adding the ISKA Unified Rules Featherweight championship to his collection.

A defining moment arrived in 2017 when he won the Rizin Flyweight Kickboxing Tournament. This victory showcased his ability to perform under immense pressure against elite competition and solidified his status as a global star. Throughout his kickboxing career, which spanned a decade, he maintained a perfect record of 40-0-0, with 32 wins coming by knockout.

In July 2022, Combat Press named him the best kickboxer under 58 kg and the top pound-for-pound fighter in the world. That same year, he announced his retirement from kickboxing to transition into professional boxing and mixed martial arts. His boxing debut came shortly after, facing Takuma Inoue in a highly anticipated bout in September 2022 that ended in a draw. The two fighters met again in September 2026 for a WBC Bantamweight Title Rematch, highlighting his continued relevance in the sport even after leaving his original discipline. [edit]

Nasukawa projects an image of a disciplined, humble, and respectful athlete who embodies the values of traditional martial arts. Media portrayals often highlight his quiet confidence and technical mastery rather than flashy personality traits. His social media presence is focused on training updates and fight promotions, reinforcing his reputation as a serious competitor.

Fans and critics alike view him as a role model for young fighters in Japan and abroad. His ability to switch from kickboxing to boxing and MMA without losing his edge has earned him widespread respect within the combat sports community. He is often described as a generational talent whose impact extends beyond his win-loss record. [edit]

One of the most legendary stories surrounding him involves his ability to outmaneuver larger opponents using speed and technical precision rather than brute strength. Fans frequently recount how he could dodge entire rounds of attacks while landing precise counter-strikes. Another notable fact is his strict adherence to traditional martial arts values, which he carries into every fight regardless of the ruleset. [edit]

Nasukawa comes from a family with a strong martial arts background. His father, Katsunori Nasukawa, was not only his first trainer but also the founder of the Ten-Shin dojo where Tenshin learned the ropes. The family environment was steeped in discipline and respect for the art of fighting. While Nasukawa has kept his romantic life private, his bond with his father remains a central theme in his public narrative.

He currently resides in Japan, maintaining a low profile outside of his training camps and fights.
