Early life, amateur shogi, apprentice women's shogi professional
Satomi was born in Izumo, Shimane on March 2, 1992. In 2003, she represented Shimane Prefecture in the 28th Elementary Student Meijin Tournament as a fifth-grade elementary school student, and advanced to the semifinals before losing to future shogi professional Takuya Nishida.

Later in 2003, Satomi entered the Japan Shogi Association's Women's Professional Apprentice League under the guidance of shogi professional Keiji Mori. She was awarded the rank of women's professional 2-kyū in October 2004.

Women's shogi professional
In September 2008, Satomi defeated Tomomi Kai to in the final of the 16th Kurashiki Tōka Cup challenger tournament to advance to the best-of-three title match against Ichiyo Shimizu. Satomi's victory over Kai also meant that she satisfied the criteria for promotion to women's professional 2-dan. Satomi went on to defeat Shimizu 2 games to none to win her first major title. Satomi successfully defended her title from 2009 (17th Kurashiki Tōka Cup) until 2012 (20th Kurashiki Tōka Cup). Satomi's victory in 2012 qualified her for the lifetime title of "Queen Kurashiki Toka", thus making her at 20 years old the youngest women's professional to ever qualify for a lifetime title. Satomi lost to Kai 2 games to 1 in the final of the 21st Kurashiki Tōka Cup in November 2013, but recaptured the title from Kai in November 2015 by the score of 2 games to none in the 23rd Kurashiki Tōka Cup. She successfully defended her title in both 2016 (24th Kurashiki Tōka Cup) and 2017 (25th Kurashiki Tōka Cup).

In February 2019, Satomi defended her Women's Meijin title against Sae Itō, winning the 45th Women's Meijin match 3 games to 1. Satomi's win was the tenth consecutive time she's won the Meijin title, which tied the record for consecutive wins of a women's title set by Naoko Hayashiba in 1991.

Satomi earned the right to challenge Tomoka Nishiyama for the 12th Women's Jo-Ō title in April–May 2019, but Nishiyama defended her title 3 games to 1.

In June 2018, Satomi lost her Women's Ōi title to challenger Mana Watanabe 3 games to 1 in the 29th Women's Ōi title match. The two met again the following year in the 30th Women's Ōi title match (May–June 2019), and Satomi regained her title 3 games to 1. The victory was Satomi's fifth Women's Ōi title overall, which not only returned her to 5-crown title holder (五冠) status, but also earned her the lifetime title "Queen Ōi".

In September 2019, Satomi defeated Kai 3 games to none to win the inaugural Seirei (shogi). The win made Satomi the first 6-crown title holder in women's professional shogi. Satomi, however, was only able to retain her 6-crown status for about two months and dropped back down to 5-crown status after losing the 41st Women's Ōshō title to Nishiyama 2 games to 1.

Satomi won the Women's Meijin title for the eleventh consecutive time when she defeated Yuki Taniguchi 3 games to none to win the 46th Women's Meijin match. The victory also gave Satomi sole possession of the record for the most consecutive wins of a women's major title.

In June 2020, Satomi successfully defended her Women's Ōi crown by defeating Momoko Katō 3 games to none.

In July–August 2020, Satomi defeated Hatsumi Ueda 3 games to 2 to win the 2nd Seirei title match. Satomi won the first two games, lost the next two, but came back to win the final game of the match and defend her title.

Satomi successfully defended her Women's Ōi crown in June 2021 by defeating Kotomi Yamane 3 games to none to win the 32nd Women's Ōi title match. The victory was Satomi's 44th major title and made her the all-time Women's professional shogi major title leader. She returned to 5-crown status in November 2021 after defeating Nishiyama 2 games to 1 to win the 43rd Women's Ōshō title. Later that same month, however, she was unable to defend her Seirei title against Katō and lost the 3rd Seirei title match (September –November 2021) 3 games to 2. Satomi and Katō also faced each other in the best-of-three 29th Kurashiki Tōka Cup title match (November 2021) with Satomi winning 2 games to 1 for her twelfth Kurashiki Tōka Cup title overall. A few weeks later, Satomi returned to 5-crown status after defeating Nishiyama in the 11th Ōza title match (October 2021 –December 2021) 3 games to none. The win was Satomi's fifth Ōza title overall which qualified her for the "Queen Ōza" title.

In February 2022, Satomi lost the 47th Women's Meijin title (January –February 2022) to Itō 3 games to 1. It was the first time since 2009 that she was unable to successfully defend her Women's Meiiin title.

Satomi, however, did recapture the Seirei title by defeating Katō in the 4th Seirei Title Match (July –August 2022) 3 games to none to return to 5-crown status.

On October 21, 2022, Satomi returned to 6-crown status after defeating Nishiyama in the best-of-seven 2nd Hakurei title match (August 2022 –October 2022) 4 games to 3. The win was Satomi's 50th major title overall. Satomi's return to 6-crown status, however, was short-lived after she lost the 34th Women's Ōshō title match (October 2022) a week later to Nishiyama 3 games to 2. Satomi and Nishiyama faced each other yet again in a major title match a few days later with Nishiyama challenging Satomi for her Kurashiki Tōka Cup title.

Satomi, however, was unable to defend her Hakurei title and dropped back down to 4-crown status after losing the 3rd Hakurei title match (September –October 2023) to Nishiyama 4 games to 3. Satomi faced Nishiyama in a major title match for the third time in 2023 and defended her Kurashiki Tōka Cup title by winning the 31st Kurashiki Tōka Cup title match (November 2023) 2 games to none.

Notable results against regular professionals
On June 28, 2019, Satomi defeated shogi professional Ryūma Tonari in the preliminary round of the 91st Kisei tournament to become the first women's professional to win four consecutive official games against regular professionals. She was, however, unable to extend winning streak to five games when she lost to Takahiro Ōhashi in her next game against a regular professional. On July 21, 2019, Satomi became just the third women's professional to win a NHK Cup TV Tournament game against a male professional when she defeated Issei Takazaki in Round 1 of the tournament.

On May 27, 2022, Satomi defeated Yūta Komori in the preliminary round of the 48th Kiō tournament to become the first women's professional to qualify for the main challenger tournament of a major title. Her record against regular professionals after this win improved to 10 wins and 4 losses over the last 14 games, satisfying the criteria to qualify for the Professional Admission Test. In addition to Komori, the regular professionals Satomi defeated during this period included former Kiō challenger Kei Honda, B1 class professional Shingo Sawada, and 2022 Ōi league winner Takashi Ikenaga. Satomi is the first women's professional to qualify for the professional admission test.

Apprentice professional
In April 2011, Satomi, who was already quite successful as a women's shogi professional, informed the Japan Shogi Association of her desire to enter its apprentice school at the rank of apprentice professional 1-kyū in an attempt to obtain full professional status. A series of three official games against existing shogi apprentices were arranged as her entrance exam. She split the first two games held on May 3, 2011, but then won the third game on May 21, 2011, to pass the exam. She was awarded the rank of apprentice 1-kyū that same day.

In January 2012, Satomi became the first female under the current apprentice system to be promoted to the rank of apprentice 1-dan after she achieved the threshold of 12 wins and 4 losses in apprentice school play. In July 2013, Satomi then became the first female to be promoted to apprentice 2-dan after once again reaching 12 wins and 4 losses. In December of that same year, she became the first female to be promoted to apprentice 3-dan, thus earning her the right to be the first female to participate in the 3-Dan League: the final stage for those aspiring to be awarded regular professional status.

Satomi's first season of 3-dan league play was supposed to be the 55th 3-dan League (April 2014 –September 2014), but health issues forced her to take a leave of absence from all professional games from April 1, 2014, until August 31, 2014. Satomi's health problems did not improve, so her leave of absence was subsequently extended to December 31, 2014; this meant she would miss the 56th (October 2014 –March 2015) 3-dan League as well. On November 10, 2014, the JSA announced that Satomi would be returning to official women's professional shogi play as of January 1, 2015, but that she was being allowed to withdraw from the 57th (April 2015 –October 2015) 3-dan league.

Satomi's returned from her leave of absence for the 58th (October 2015 –March 2016) 3-dan League, and finished with a losing record of 5 wins and 13 losses. Her records in the 59th (April 2016 –September 2016), 60th (October 2016 –March 2017) and 61st (April 2017 –September 2017) 3-dan Leagues were 7–11, 8–10 and 7–11 respectively.

Satomi was already 25 years old when she started 62nd (October 2017 –March 2018) 3-dan league play which meant she needed to either win the league outright and obtain full professional status, or finish with a winning record (10 wins) to avoid losing her qualifications for the apprentice school due to the 26-year-old age limit set in place by the JSA. Satomi's record after twelve games was 7 wins and 5 losses, so it seemed like she might be able to qualify for a one-season extension to continue her attempt for full professional status. However, she proceeded to lose her next four games which meant the best she could finish was 9 wins and 9 losses, which confirmed that she would have to leave the apprentice school. The option of becoming a "regular" professional via the Professional Admission Test remains open to her, and her leaving the apprentice school does not affect her status as a women's professional player.

Professional Admission Test
On June 28, 2022, the JSA announced that it had accepted Satomi's application for the Professional Admission Test. Satomi was the first woman to be accepted for the test. She satisfied the criteria for the test the previous month when she defeated a regular professional in the official tournament play. Satomi's test consisted of a best-of-five test match against the five most recently promoted regular professionals with Satomi needing to win three of the five games to be awarded regular professional status as a "Free Class" professional. The schedule was for one game to be played a month starting in August 2022, under official game conditions.

The five professionals Satomi was scheduled to play were Kenshi Tokuda (Game 1), Reo Okabe (Game 2), Mikio Kariyama (Game 3), Tomoki Yokoyama (Game 4) and Akihiro Takada (Game 5). The time control for each game was three hours per player which was then followed a byoyomi time control of thirty seconds per move. A furigoma was held prior to Game 1 to determine who moved first, and then the first move alternated between players for the remaining games so that Satomi would never move first or second for two consecutive games. The games were scheduled to take place at the JSA headquarters in Tokyo and its Kansai Branch in Osaka. Game 1 took place on August 18 in Osaka with Tokuda moving first and ultimately winning in 127 moves. Game 2 took place in Tokyo on September 22, with Satomi moving first. Despite having the advantage of the first move, Satomi lost the game in 132 moves. Game 3 took place in Osaka on October 13 with Satomi needing to win to have any chance of being promoted; Satomi lost the game in 103 moves which meant she had failed the test, thus making Games 4 and 5 unnecessary.

Personal life
Satomi's younger sister Saki is also a women's professional shogi player. The two are the third pair of sisters to be awarded women's professional status by the JSA.

On January 1, 2024, the JSA posted on its official website that Satomi had gotten married during 2023 and would now be competing under her married name Fukuma (福間). In a Chunichi Shimbun article published later that same day, it was further revealed that she had married former apprentice professional 3-dan Kenta Fukuma.
