Sugiuchi Kazuko

Sugiuchi Kazuko (Kanji: 杉内 寿子; Katakana: スギウチ　カズコ), née Honda Kazuko (本田 寿子, born 6 Mar 1927, Kannami Village, Tagata District, Shizuoka Prefecture) is a Nihon Ki-in female professional Go player. She won 10 women’s titles in her long career. She may have won many more, had she not given up 10 of her prime years (most of her 30s) to prioritize raising her children. Even in her 60s, she was the #2 rated Japanese woman for two years.

Family and name

Sugiuchi’s given name is 寿子, which is read “Kazuko” in her case, but can also be read “Hisako” (both are kun readings of the characters). Her Nihon Ki'in] profile also lists the name in the syllabic Katakana script to provide the right pronunciation. The name means a child with a long life or congratulations, which certainly fits her very well!

She learned Go from her father Eizo, a retired naval captain, starting at age 6. Eizo was inspired by the achievements of the top female professional Ito Tomoe, and encouraged Kazuko to learn Go to a high level. She was introduced to some professional players, and became Kita Fumiko’s student in 1937.

Sugiuchi Kazuko is the eldest of three professional Go-playing sisters, all of whom have won the strongest women’s tournaments. The other two are the late Honda Sachiko 6P (post-retirement promotion to 7P, posthumous promotion to 8P) and the retired Kusunoki Teruko 7P (post-retirement promotion to 8P).

She met her husband Sugiuchi Masao at the Fugyoku-kai, a research organization for young Go players. They married in 1954, and were married for 63 years until his death in 2017. In 1956, after her promotion to 6-dan, Kazuko took a 10-year break from Go to raise their children.

Three Honda sisters

Sugiuchi Kazuko is the eldest of three professional Go-playing sisters, all of whom have won the strongest women’s tournaments. The other two are the late Honda Sachiko 6P (post-retirement promotion to 7P, posthumous promotion to 8P) and the retired Kusunoki Teruko 7P (post-retirement promotion to 8P). They have won 24 titles between them.

The oldest, Kazuko, was a student of Kita Fumiko. Sachiko and Teruko studied under Kitani Minoru.

Go career

Sugiuchi became a pupil of Kita Fumiko starting age 10 in 1937. Kita was already 62 when Kazuko became her student, probably youngest as well as her best (except perhaps Ito Tomoe). Most of Kita’s pupils started knowing nothing about Go, and were sent to live with her to learn a trade (Go teacher). But Kazuko was an exception. Kita witnessed her beat Kitani Minoru in an exhibition game on 5 stones aged only 10, and went to her home to recruit her. Her father enthusiastically agreed.

Sugiuchi became a professional in 1942. In 1944, she won all her games in the Oteai second division. As WW2 progressed, Kazuko, still a teenager, and her younger sisters were evacuated to the countryside.

In 1951, she was runner up in a Young Players’ Championship. In 1953, as a 4-dan, she won the All-Japan Women's Championship from Ito Tomoe, another student of Kita Fumiko, and the inspiration for Kazuko's father to teach her Go. Sugiuchi defended next year against Suzuki Tsuna, another Kita student, followed by rebuffing Ito's challenges in the next two years. Then Sugiuchi temporarily retired for 10 years to raise her children, and Ito won the title five times in a row. During Kazuko's retirement, her husband had some of his best results: challenging for Honinbo in 1958 (for the second time), and won the Tokyo Shinbun Cup in 1962 and the Hayago Meijin in 1959.

Sugiuchi became the first woman to be promoted to 7-dan in 1973, then the first to reach 8-dan in 1983. She also won the Women's Kakusei in 1983 and 1986. Sugiuchi won the Women's Meijin from 1991–1994, losing in 1995 to her pupil Kato Tomoko, 42 years younger. At the age of 72, she was runner-up to Kobayashi Izumi, 50 years younger, in the 2nd Female Kisei in 1999.

Before December 2012, Sugiuchi held the record for most wins by a female professional in Japan (589 wins in professional games in her career). But Yoshida Mika beat the record by winning her 590th game on 6 December 2012. Sugiuchi reached 600 wins in 2014. As of 27 Aug 2024, she has won 635 games.

She and her husband attended the seventh U.S. Go Congress in Rochester, NY, in 1991. Her husband died in 2017, and Sugiuchi Kazuko’s tribute at the funeral included “Live in a pure world and die in a clear winter.”

Kato Tomoko and Kanno Naomi are Sugiuchi’s pupils.

Until 2004, Sugiuchi served as the president of the Nihon Ki-in Go Players Association and the president of the Women's Go Players Association?.

Go playing in her 90s

After her husband’s death in 2017, Sugiuchi returned at the age of 91 to active play, competing for all 7 Japanese titles and 4 female tournaments. She loses more games than she wins, but is still a very dangerous opponent. E.g. in 2019, aged 92 she beat 50-years–younger Mizokami Tomochika 9P with White, and Fukui Masaaki 9p with Black—but he is only 17 years younger. The same year, Sugiuchi beat Mizokami’s wife Kato Keiko, 6P and former Women's Meijin, 51 years younger. Sugiuchi Kazuko, Go rating profile and game list Also in that year, she won the preliminary rounds at the 38th Female Honinbo Tournament in 2019 and became the oldest player to advance to the main tournament. She broke her own previous record of 88 at the 34th Female Honinbo tournament in 2015.

In 2023, Sugiuchi set a new record for the oldest professional to win an official game (with kifu), aged 96 years and 1 month. In the Judan tournament, she beat Yokota Hinano 1p, 77 years younger, a record for the largest age difference for a victorious older player.

On 11 April 2024, she became the oldest professional to play a game: 97 years, one month, and five days, a loss against Morita Michihiro 9p (53 years and 6 months old). https://www.163.com/dy/article/IVHFDT5R0529BOGK.html The previous record was set by none other than her late husband Sugiuchi Masao 9p, who was 97 years and 13 days old when he lost to 47-year-old female 6p Koyama Terumi on 2 November 2017.

Sugiuchi Kazuko might be on track to beat another record: oldest pro to win any tournament game—also set by Sugiuchi Masao, 96 years and 10 months. https://www.reddit.com/r/baduk/comments/12xh7yw/age_is_just_a_number_96yearold_go_master_sets_a/

If she played the new star Nakamura Sumire in a tournament, this would be an age difference of 82 years. This would break the previous record of the largest age difference between players in Nihon Kiin history—the 80 years also held by her late husband. https://www.nihonkiin.or.jp/match_news/match_info/801595.html
