Profile

Nadaka Yoshinari is a historical outlier.

He debuted professionally at Lumpinee Stadium at 14 years old, something virtually unheard of for a foreign fighter, and did not merely participate — he won titles. By his early twenties, Nadaka had captured championships across nearly every major Thai and international sanctioning body, becoming the only foreign fighter ever to win titles in three weight divisions at Rajadamnern Stadium.

Where many foreign fighters adapt to Thai rules, Nadaka mastered them. He reads tempo, distance, and scoring criteria like a stadium veteran, not an outsider.

Fighting Style

Nadaka is a pure technician, built for five-round Muay Thai.

Key traits:

  • Exceptional timing and vision

  • Precise counter-kicking and body attacks

  • Sharp elbows at close range

  • Composure under pressure

  • High ring IQ and scoring awareness

He does not rely on physical dominance. His success comes from control, particularly against aggressive Thai opposition.

Stadium Career & Thai Credentials

Nadaka’s stadium résumé is unprecedented for a non-Thai fighter.

Rajadamnern Stadium

  • Mini Flyweight (105 lbs) Champion — 2018

  • Flyweight (112 lbs) Champion — 2023

  • Super Flyweight (115 lbs) Champion — 2024

  • Multiple successful defenses

Lumpinee Stadium

  • Mini Flyweight (105 lbs) Champion — 2019

He is only the second foreign fighter in history to win titles at both Lumpinee and Rajadamnern Stadiums.

World & National Titles

Across his career, Nadaka has captured titles from nearly every major governing body:

  • WMC World Champion

  • WBC Muaythai World Champion (multiple divisions)

  • IBF Muaythai World Champion

  • WPMF World Champion

  • PAT (Thailand) Champion

  • BoM Flyweight Champion

By his mid-twenties, he had already become a five-division champion.

ONE Championship Era

In 2025, Nadaka signed with ONE Championship and quickly established himself at the highest level.

  • Inaugural ONE Atomweight Muay Thai World Champion

  • Won the title via five-round unanimous decision in Tokyo

  • Named 2025 ONE Muay Thai Fighter of the Year

His transition to ONE did not alter his style — he brought stadium Muay Thai directly onto the global stage.

  • The most successful foreign fighter in Thai stadium history

  • A technical benchmark for lighter-weight Muay Thai
