Chiaki Ishii

Chiaki Ishii was born on 1 October 1941 in Ashikaga, Tochigi Prefecture, Japan, the youngest son of a large judo family. His father, Yukichi Ishii, named him Chiaki, written with characters meaning "a thousand autumns", before being sent to the Second World War front while his mother, Harue, was pregnant. Yukichi, who served in Burma and Sumatra according to a 2016 interview with Ishii, was held as a prisoner of war and only met his son years later. The family's martial arts lineage ran deep. In Ishii's own account, his grandfather Seikichi practised jujutsu and was invited by Kodokan founder Jigoro Kano to join the Kodokan, receiving sixth dan on entry, and the Brazilian Olympic Committee notes that his great-grandfather founded the Zoshikan martial arts academy. All of Ishii's brothers and sisters trained. He started judo at four or five under his father and later recalled brutal summer and winter training camps that made him the toughest boy in school.

Ishii earned his black belt in middle school and was third dan in high school. He then entered Waseda University in Tokyo, whose judo club then had about 150 members, and was promoted to fourth dan soon after enrolling. Sources differ on his field: the Brazilian Olympic Committee says he studied history, while other accounts say pedagogy. He trained morning, noon and night with the aim of making Japan's team for the 1964 Tokyo Olympics, and he graduated in March 1964.

In the 1963 Japanese Olympic trials Ishii lost to Isao Okano, who went on to win gold in Tokyo. Heartbroken, he emigrated to Brazil, arriving at Santos on 2 May 1964 after a 60 day voyage from Yokohama with about 300 other Japanese emigrants. He worked as an agricultural immigrant in Presidente Prudente, entered and won Japanese Brazilian tournaments almost at once, taught in rural dojos, and wrestled sumo, winning the all-Brazil sumo championship five times by 1971 according to Japanese Wikipedia. After about two years travelling through Bolivia, Argentina, Chile and Peru challenging local clubs, he settled in São Paulo and opened his own academy in 1968.

At the suggestion of Augusto Cordeiro, president of the Brazilian Boxing Confederation, which then administered judo, Ishii was naturalised as a Brazilian in 1969 (one 2014 Brazilian Judo Confederation article gives 1967). He won national, South American and Pan American titles, including the open class at the 1970 Pan American Championships in Londrina. To sharpen his groundwork he cross-trained in sumo, open-weight judo and Brazilian jiu-jitsu and lifted weights, later claiming a 180 kg bench press. In 1971 he won bronze at the World Championships in Ludwigshafen, Brazil's first world medal in judo.

Before Munich he trained for three months in Japan with his brother Kiyoshi. At the 1972 Olympics he threw Senegal's Mohamed Dione for ippon in 16 seconds and won his second bout by ippon in 38 seconds, then lost a hantei decision to West Germany's Paul Barth that he always disputed. He came back through the repechage to win bronze in the light heavyweight (under 93 kg) class, Brazil's first Olympic judo medal. A loss to Britain's David Starbrook ended his hopes of the final.

After Munich he devoted himself to teaching at his academy, later known as the Associação de Judô Ishii, in Lapa, São Paulo. He trained the Brazilian national team, studied opponents on video with athletes and acted as the team's strategist in the build up to Los Angeles 1984. Olympic medallists Walter Carmona and Rafael Silva trained under him. In 2016, aged 75, he returned to competition and won gold at the World Veterans Championships in Fort Lauderdale.

Ishii married Keiko, his fiancée from Japan, who travelled alone to Brazil in the 1960s to keep her promise to marry him. He affectionately called her "my lady". They had three daughters, Tânia, Luiza and Vânia, all judo black belts. Tânia competed at the 1992 Barcelona Olympics, won the 1986 Pan American Championships and married Mike Swain, the American Olympic bronze medallist and world champion. Vânia competed at the Sydney 2000 and Athens 2004 Olympics and won gold, silver and bronze medals at the Pan American Games. Ishii had three granddaughters and one grandson, including Sophia Swain, a US Open judo champion, and Masato, a basketball player. His daughters described him as quiet, stern and demanding on the mat, a lover of reading, writing and history. In later years he spent weekends at a country property in Ibiúna, near São Paulo, growing flowers and vegetables and playing golf.

Ishii believed confidence was what Brazilian judo had lacked. "It changed everything," he said of his medal. "There was a lack of confidence back then. Judoka started to think they could win too." In a 2016 interview with Brazil's Japanese language press he criticised modern training for having fewer gruelling randori sessions and urged athletes to fight with their own decisive techniques rather than chasing decisions. Colleagues such as Olympic champion Sarah Menezes described him as a living example of bushido values of humility, courage and discipline.

Ishii's bronze in Munich opened a path that turned judo into Brazil's most decorated Olympic sport, with 28 medals by 2026. Luiz Onmura, who won Brazil's second Olympic judo medal in 1984, said clubs and academies filled up after Ishii's success. Olympic champions Aurélio Miguel and Rogério Sampaio trained with him, and his first live-in student, Uichiro Umakakeba, later became the first teacher of double Olympic medallist Tiago Camilo. The Ishii family is often called a family of Olympic pioneers, spanning Chiaki, his daughters Tânia and Vânia, and his son-in-law Mike Swain.

In March 2014 Ishii published a book in Japanese about the pioneers of Brazilian judo, followed by a Portuguese edition in November 2015 produced with the help of his students. His life was the subject of documentaries including "Chiaki Ishii: O Samurai Brasileiro" and "Chiaki Ishii: O Bronze de Mil Outonos" ("The Bronze of a Thousand Autumns"), and of an ESPN Brasil "Histórias do Esporte" episode with his daughter Vânia.

Chiaki Ishii died on Friday 16 October 2026 in São Paulo, aged 85. The cause of death was not made public. Years earlier his family had said he nearly died around 2016, and in 2019 he was recovering from a health problem at home when the Brazilian Judo Confederation visited to announce its Order of Merit. The Confederation announced his death, writing that Brazilian judo was in mourning and that his example would inspire for many years. Its president, Paulo Wanderley, called him "a pioneer who believed in Brazil's potential", and the Brazilian Olympic Committee said the master had opened the way for generations of athletes.
