Fujisawa Rina

Fujisawa Rina (藤沢里菜) is a Japanese professional female go player, born 1998-09-18, who passed a pro exam in 2010 while in the fifth grade of elementary school. On April 1st 2010, she received her professional diploma at the age of 11 years and 6 months, making her then the youngest person in Japan to become a professional ^[1]. The previous record was held by Cho Chikun who became a professional when he was 11 years 9 months old. Cho played a game with her to mark the occasion, and in a video commentary of her game with Rin Kanketsu in the NHK Cup, 2015, Cho said that she had a great future and could play any style. https://www.youtube.com/watch?v=J-Y1p2ZQDq0

Fujisawa began learning Go at the age of 6 and studied under the tutelage of Hong Malk-eun Saem. She was promoted 2 dan in 2013-02-14 (30 wins as 1 dan).

Rina started 2014 with 9 consecutive wins (as of 2014-02-15), extending her winning streak to 9 games.

In 2014, she was part of Japan team at the 4th Huang Longshi Shuang Deng Cup. She won against Song Ronghui in the fourth game, but lost to Kim Hye-min in the fifth game. In the same year, she became the youngest Female Honinbo in Go history by defeating Mukai Chiaki (title holder) 3–0 in the 33rd title match, at the age of 16 years and 1 month old. She lost the title to Xie Yimin 3–2 the next year, then regained it 3–1 the following year. She was the winner of the 1st Aidu Chuo Hospital Cup (2014), beating Okuda Aya by resignation.

In 2016, Fujisawa won the 2nd Ibero-Japan Cup?, an U-18 tournament open to both sexes, the second female winner after Xie Yimin.

In 2017, she probably became the strongest female player in Japan. In March, Fujisawa won the Female Meijin, beating title-holder Xie Yimin 2–0, ending her streak of 9 wins in a row. In June, she beat the same opponent 2–1 to win the Aidu Chuo Hospital Cup (Aizu Central Hospital Cup), and next month she beat Xie again to win the Senko Cup?.

In 2018, Fujisawa defended her Female Meijin by beating Yashiro Kumiko 2–0, and her Aidu Chuo Hospital Cup title by defeating Xie Yimin 2-1.

• valerio: Rina started 2013 with 4 wins in a row and in 2013-02-14 reached 30 wins as 1 dan, but she is still 1 dan: why?
  • RueLue: Apparently because of her win-loss ratio: 6-7, 8-15, 13-13, 9-7 (the first numbers are the wins I think)
• oren: It's possible that female only leagues do not count in the promotion system
  • valerio: yes, oren is right. For promotions, female tournaments don't count. Japanese Nihon-kiin rules and Kansai-kiin rules.
    • Not even the top titles Female Meijin and Female Honinbo?
