Ryoko Tani

In July 2012, she left the Democratic Party for the newly created and short-lived People's Life First. Later that same year, she was one of the founding members of the People's Life Party, alongside her mentor Ichiro Ozawa. Tani was approached by several parties in the lead up to the July 2016 election, but Ozawa demanded she remain with the party, as her defection would have meant the party fell below the minimum requirement of five Diet members and lost its official party status. In June 2016 Tani announced her decision to remain with the party until the election, but not seek a second term.

In 2010, she was elected to the House of Councillors, the upper house of the Japanese parliament.

She retired from competition in 2010. In a career spanning around 20 years, she was only defeated 5 times. In 2011, the International Judo Federation named her "best female judoka ever" at its 60th anniversary gala in Paris.

Tani was introduced to politics by Ichiro Ozawa. On May 10, 2010 the Democratic Party announced that she would represent the party as a proportional candidate in the Summer 2010 House of Councillors election. Tani initially stated that she still intended to pursue her judo career, but she eventually retired from judo after she won the seat in question.

In Beijing in 2008, she saw her hopes of a third-straight gold evaporate when judges awarded penalty points to Romania's Alina Dumitru after both competitors failed to show much aggression. Looking stunned, Tani fought desperately after the final controversial penalty call, but with only seconds left she had no time to mount an attack. She defeated Russia's Lyudmila Bogdanova for bronze.

Tani lost the 2007 All-Japan Weight Class Judo Championship, which doubles as the qualifier for Olympics and the World Championships on those years when the events take place, but was selected as Japan's representative anyway by the All Japan Judo Federation (AJJF). She then won the gold medal in the Rio de Janeiro World Championships. Tani lost the All-Japan again in April 2008, to 21-year-old Emi Yamagishi. Again, the AJJF selected Tani for Japan's team in place of Yamagishi. The AJJF refused to answer questions about Tani's selection after the decision, but later said that Tani was selected because "She is especially strong against international opponents". The selection prompted Philip Brasor, media commentator for the Japan Times to ask "...maybe Tani is the better choice, but why have qualifying bouts in the first place?". The AJFF uses qualifying bouts as only one criterion considered for selection, with performance in international events as another.

In 2003, she married Yoshitomo Tani, an Olympian and professional baseball player then with Orix Blue Wave. The wedding reception reportedly cost $3 million. The couple has two sons, born in 2005 and 2009.

Competing in the extra-lightweight (48 kg) class, she won a record seven world titles and five Olympic medals including two golds at Sydney 2000 and Athens 2004. After her retirement, the International Judo Federation named her "best female judoka ever".

She studied literature at Teikyo University and joined Toyota in 1998.

After 1996, she remained unbeaten for 12 years. At Sydney 2000, she had a tough semi-final against North Korea's Cha Hyon-hyang, but she left no chance to her opponent in the final, Lyubov Bruletova of Russia. After only 36 seconds, Tani delivered an uchi mata (inner-thigh throw) and was awarded an ippon and the gold metal. Four years later in Athens, she scored a series of ippon-victories to reach the final, in which she dominated France's Frédérique Jossinet, taking an early koka lead that she confirmed with a waza-ari in the last seconds of the fight. She was the first woman judoka to win two Olympic golds.

In 1993, she won her first world title and received her fourth dan. She went on to win the biennial world championships in 1995, 1997, 1999, 2001, 2003 and 2007. She did not compete in 2005 as she was expecting her first child. This record seven wins was only beaten by French judoka Teddy Riner in 2015, in an era when world championships had become annual events.

She competed in five Olympic Games and won as many medals. At Barcelona 1992, aged only 16 years old, she defeated in the semi-final veteran British fighter and 4-time world champion Karen Briggs, but she lost the final by a small margin against the reigning world champion, Cécile Nowak of France. This was followed by a 4-year, 84-match winning streak that led her to her second Olympic final at Atlanta 1996. Tani was the clear favorite against the relatively unknown North-Korean Kye Sun Hui, but she was unable to live up to the expectations. Kye resisted all her attacks and scored an advantage towards the end of the fight. Tani's second Olympic silver was a huge setback, and the Japanese media talked of an "Olympic curse". Reflecting on this years later, Tani said, "there was never a curse … in 1992, I was 16, I was lacking experience … in 1996, I was 20".

Her first major title was at the 1990 Fukuoka International Women's Judo Championships, a tournament she went on to win 13 years in a row.

Tani is credited for the boom in women's judo witnessed by Japan in the 1990s, leading to the rise of a new generation of competitors. Because she did not let her marriage put an end to her sporting career, and won her last world title as a young mother, she is also viewed as a symbol of the changing role of women in Japanese society.

Tani followed in the footsteps of Kaori Yamaguchi, who in 1984 had become the first Japanese woman to ever win a world championship – the sport had long been a male preserve. Yamaguchi was the inspiration for the character of Yawara Inokuma, the heroine of a popular manga and anime series who prepares for the 1992 Barcelona Olympics. When Tani represented Japan in Barcelona, she was viewed by the Japanese public as a real-life Yawara and was soon nicknamed Yawara-chan or Tawara.
