Records

Family

Her brother Hoshiai Shingo is a Waseda University Go Club alumnus known for winning the All Japan Student Go Best 10? in 2017 (operated by the All Japan Student Go Federation) and the 2014 High School Championship.

She married Son Makoto 7p [ext] on 7 July 2022. She posted this on her Twitter page at [ext] 15:15 on 15 July, because of a pun: 15 is written in numerals as one-five, Japanese ichi-go (1 一 ichi, 5 五 go), but this is also a classical or literary pronunciation of 一期 (normally ikki). So it had the deeper meaning of a once-in-a-lifetime event.

Book

In 2019, Hoshiai and her good friend Kibe Natsuki, then both 2 dans, published Female Go Players Photo Book. This comprised photos and interviews with 10 female Go professionals (including themselves). They hoped to raise popularity for Go. They [ext] crowdfunded for the publication costs, aiming for 1.5 million yen, but raised about 4.39 million yen.
