The story

Toshihiko Koga moved from Saga to Tokyo as a junior high student to train at the Kodogakusha school, and his spectacular ippon seoi nage, always thrown for ippon, earned him the nickname 'Heisei no Sanshiro'. After a world bronze in 1987 and an early exit at the 1988 Olympics, he won world titles at 71 kg in 1989 and 1991. During preparations for the 1992 Barcelona Games he badly injured his knee in practice with Hidehiko Yoshida, yet he still won gold, beating Hungary's Bertalan Hajtós in the final. He returned to win the 1995 world title at 78 kg and took Olympic silver in Atlanta in 1996. As a coach he founded the Koga Juku, whose pupil Ayumi Tanimoto became Olympic champion. He died of cancer in 2021, aged 53.

Steal this

Koga's ippon seoi nage relied on turning in fast and low with the elbow driving up into the opponent's armpit, so much bigger players still went over. Drill the entry from movement, especially as the opponent steps forward, and aim to finish for ippon rather than a partial score.
