Births on April 4

Katsuaki Satō, Japanese martial artist and coach

Katsuaki Satō (佐藤 勝昭), born on April 4, 1946, is a revered figure in the world of martial arts, particularly known as the visionary founder and director of Satojuku Karate, a distinctive style also celebrated as Odo (The Champion's Way) karate. His journey began on Sakhalin Island, a territory then under Japanese occupation following the tumultuous end of World War II. Though the Soviet Union had invaded the island during the war's final stages, Satō's family was among the approximately 300,000 Japanese who remained.

In 1947, when Satō was just an infant, his family relocated to Nakoso, nestled within Japan's Fukushima Prefecture. His formative years saw him immerse himself in judo training during high school. This dedication continued after graduation, as he balanced full-time work as a journalist with part-time studies at Chuo University, all while pursuing his passion for judo.

From Judo to Kyokushin Karate

A pivotal moment arrived for Satō at the age of 20 when significant knee and shoulder injuries forced him to step away from judo. Undeterred, he sought a new path in martial arts, discovering Kyokushin karate in 1969. This transition marked the beginning of a profound dedication to karate. He studied under the tutelage of Terutomo Yamazaki, a master for whom Satō has consistently expressed deep respect and admiration. His disciplined training quickly bore fruit: he achieved the rank of Shodan (1st-degree black belt) on October 1, 1971, swiftly followed by a 3rd dan in karate on March 18, 1973. Remarkably, he had also attained a 3rd dan ranking in judo, showcasing his versatile prowess. By May 1, 1974, Satō had reached the impressive rank of 4th dan in karate.

A Champion's Rise: Tournament Success

Katsuaki Satō didn't just train; he excelled in the crucible of tournament competition, leaving an indelible mark on the world of full-contact karate. His competitive spirit led him to victory at both the 1971 (Third) and 1974 (Sixth) All-Japan Full Contact Karate Championships (AJFCKC). The pinnacle of his competitive career arrived in 1975 when he secured the title at the inaugural First All-World Full Contact Karate Championships (AWFCKC). During this era, Satō was recognized as part of an elite Kyokushin training group affectionately dubbed "The Seven Samurai," which included formidable competitors like Jōkō Ninomiya. Notably, Satō famously defeated Ninomiya on his path to claiming that prestigious 1975 Kyokushin world title.

Physically imposing, Satō was recorded in 1976 at 5' 10½" (179 cm) and 183 lb. (83 kg). Later sources refined these measurements to 1.80 m (5 ft 11 in) and 90 kg (200 lb; 14 st), reflecting his powerful build. Following his triumph in 1975, Satō made the significant decision to retire from full-time karate training and competition, choosing instead to dedicate his efforts to assisting his family's business.

Founding Satojuku: The Champion's Way (Odo)

In 1977, Katsuaki Satō embarked on a new chapter, establishing his own distinct karate style, Satojuku, in Mitaka, Tokyo. Starting with a single dojo (training hall), Satojuku has since flourished, growing to encompass numerous dojo across Japan, its honbu (headquarters) now located in Tachikawa. While sharing stylistic similarities with Kyokushin, Satojuku distinguishes itself by placing a unique emphasis on precise knockdown techniques. Rather than focusing solely on techniques designed to injure or "knock-out" an opponent, Satojuku champions controlled, effective strikes aimed at achieving a knockdown. The organization proudly sponsors an annual event, the All-Japan Point & K.O. Tournament, held at Tokyo's iconic Yoyogi National Gymnasium, featuring robust full-contact, knockdown rules of competition.

Satō himself eloquently articulated the philosophy behind his art in 1987, stating, "Odo means the way champions must behave. It is based on humane feelings and courtesy, on being honorable, on being devoid of selfishness or bias. It is the antithesis of any martial art that relies only on force to conquer an opponent." This profound statement encapsulates the ethical and moral foundation of Satojuku Karate, reflecting a holistic approach to martial arts that transcends mere physical prowess.
