Career

Koseki was inspired to take up boxing after watching Hiroshi Kawashima on TV. Koseki won the inaugural All-Japan women's amateur championships in 2003, as well as the second edition in 2004. After winning a third national amateur title in 2007, she decided to turn pro as women's boxing was not yet accepted as an Olympic sport.^[1]

Koseki won her first three bouts. She went on to challenge Winyu Paradorngym for the inaugural WBC atomweight world title. Winyu won the fight by unanimous decision.^[2] In her next fight, Koseki moved up two weight classes to challenge for the WBC light flyweight title, but lost again by unanimous decision.^[3] In August 2008, Koseki rematched Paradorngym, and won the title with a round 2 knockout at Korakuen Hall. In August 2014, Koseki made her fourteenth consecutive defense, beating Denise Castle with a round 8 technical knockout. With the win, Koseki broke Yoko Gushiken's Japanese national record of 13 consecutive successful world title defenses.^[4] In October 2015, Koseki beat WBA champion Ayaka Miyao by unanimous decision to make her sixteenth defense and unify titles.^[5]

Koseki won the WBC minimumweight title on 17 December 2017, defeating reigning champion Yuko Kuroki by decision.^[6]

She retired on 29 January 2018, at the age of 34.^[7]^[8]
