The original Ajigawa stable was established in April 1979 by former
sekiwake Mutsuarashi. He had originally hoped to become head of
Miyagino stable and had married the daughter of the incumbent stablemaster there, but the marriage ended in divorce. He moved to
Tomozuna stable upon his retirement in 1977 before opening up his new stable two years later. Ajigawa stable absorbed
Kasugayama stable in 1990 on the retirement of its head coach. In April 1993
Asahifuji acceded to the Ajigawa name and took over the stable, due to the poor health of the incumbent. In late 2007 Asahifuji switched to the prestigious Isegahama
elder name which had become available upon the retirement of its previous holder, former
maegashira Katsuhikari, thereby also changing the name of his stable. Asahifuji's decision to switch to the Isegahama name can be seen as an attempt to restore his
ichimon reputation (the
ichimon was known as Tatsunami-Isegahama for many years before becoming solely Tatsunami; as a result of the success of the renamed stable the
ichimon has been solely known as Isegahama since January 2013). He also moved the stable to new premises. In September 2012,
ōzeki Harumafuji won his second consecutive tournament and was promoted
yokozuna for the next tournament. In March 2013, the stable absorbed the coach and wrestlers (
Terunofuji, Wakaaoba and Shunba) of the
Magaki stable. Magaki was shut down due to the poor health of
Magaki-oyakata. Isegahama stable had four of its wrestlers ranked in the
makuuchi and
jūryō divisions in 2017, although Harumafuji retired in November 2017 and
ōzeki Terunofuji fell to the lower divisions through injury in 2018 before staging a successful comeback, eventually reaching the rank of
yokozuna in July 2021. In March 2022, the stable managed to have six active
sekitori wrestlers at the same time, with the promotion of, then 19 year-old, Atamifuji to the
jūryō division for the March tournament, after a winning record at the top of the
makushita division. In November 2022, the stable managed, in another rare occurrence, to have all six
sekitori of the stable ranked at the elite first division
makuuchi, with the promotion of then 20 year-old Atamifuji to the rank of
maegashira 15. The last time a stable had six
sekitori in the
makuuchi division was
Musashigawa stable in March 2004. In December 2022, two junior wrestlers in the stable were found to have acted violently against younger wrestlers, with the victims beaten with wooden beams and burned with
chankonabe hot water poured on their backs. One of the wrestlers held responsible submitted his retirement papers, while another was handed a two-tournament suspension. Following the investigation, stablemaster Isegahama (
Asahifuji) resigned his seat on the Sumo Association's board of directors. In March 2024, the Sumo Association announced the temporary closure of
Miyagino stable—also part of the Isegahama
ichimon—and the transfer of its personnel to Isegahama stable for an indefinite period of time. This occurred in the aftermath of physical abuse at Miyagino stable from the former
Hokuseihō and the subsequent punishment and demotion of its stablemaster, the 69th
yokozuna Hakuhō. Following the resignation and final retirement of former stablemaster and coach Miyagino (the 69th
Hakuhō) in June 2025, all members of the former Miyagino stable were instructed to remain under the tutelage of Isegahama stable. With the publication of the
banzuke for the January 2025 tournament, Isegahama stable became the first stable in 22 years to include seven of its wrestlers in the
makuuchi division, a first since
Musashigawa stable ranked seven of its own at the
September 2003 tournament. The Sumo Association announced in June 2025 that
Terunofuji would take over the Isegahama
elder stock and stable, due to the former Asahifuji reaching sumo's mandatory retirement age of 65 the following month. Three of Isegahama's -ranked wrestlers collected five , or wins over , at the January 2026 tournament.
Yoshinofuji collected two on consecutive days, marking the first time that had happened in professional sumo in six years. The same feat was accomplished later in the tournament by eventual runner-up
Atamifuji. A former Miyagino stable wrestler,
Hakunofuji, won against
Ōnosato on Day 8. In February 2026, the Japan Sumo Association's compliance committee was reportedly investigating allegations that the former Terunofuji physically assaulted
Hakunofuji. ==Ring name conventions==
