The story

Ryoko Tamura, later Tani, stood 1.46 m and never had to cut weight for the 48 kg class she ruled for almost two decades. She won world bronze at 15 and reached the Olympic final at 16, losing to France's Cécile Nowak in Barcelona. An 84-match winning run followed, only for North Korea's Kye Sun-hui to upset her in the 1996 final. She finally won Olympic gold in Sydney in 2000 with an uchi mata ippon and defended it in Athens, the first woman to win two Olympic judo titles. She won seven world titles, the last in 2007 after the birth of her first child, and took a medal at five straight Games. Japan knew her as Yawara-chan, and she later served in the national parliament.
