The stable is one of the most prestigious in sumo. It was founded in 1876 by
Onigazaki, but the current incarnation dates from 1915. In the 1930s, led by former
komusubi Midorishima (1878-1952), the stable produced the 35th
yokozuna Futabayama, the 36th
yokozuna Haguroyama and
ōzeki Nayoroiwa, Futahaguro was forced to leave the
Sumo Association as a result. although the award was reversed. Annenyama also attempted to evict Asahiyutaka from the stable premises. In April 2011, the stable's last
sekitori at that point, the
Mongolian wrestler
Mōkonami, was forced to retire after being found guilty of
match-fixing. Tatsunami stayed five and a half years without any wrestlers in the top two professional divisions, before
Meisei was finally promoted to
jūryō after the September 2016 tournament. Meisei made the top division in July 2018. Another notable member is
Hanakaze, who holds the distinction of having the longest career in the centuries long history of sumo, a career that began in 1986, one year before his current stablemaster. The stable's success was reflected in its postwar status as the leading stable in its
ichimon or group of stables, which was called Tatsunami-Isegahama
ichimon until 2006, when it became simply Tatsunami
ichimon (reflecting the decline of the old
Isegahama stable under former
ōzeki Kiyokuni's leadership). However, in 2012, due to the head coach voting against the
ichimon's will in the Sumo Association's board elections, Tatsunami stable moved to the Takanohana
ichimon. Tatsunami
Ichimon then renamed itself Isegahama
Ichimon in January 2013. Tatsunami stable went independent in 2018, but after the Sumo Association indicated that stables must belong to an
ichimon, it aligned itself with the Dewanoumi group. The stable's foreign recruit is
Hōshōryū, the Mongolian nephew of former
yokozuna Asashōryū, who joined the stable in November 2017 and made his first tournament appearance in January 2018. He became a
sekitori in November 2019 and reached the top division in September 2020. He was promoted to
komusubi in March 2022, elevated to
sekiwake in September 2022, and was promoted to
ōzeki after winning his first top-division championship in July 2023. Hōshōryū was promoted to
yokozuna in January 2025. In November 2020,
Akua became the fifth member of Tatsunami stable to reach the top division under the present stablemaster, following
Ōhinode, Mōkonami, Meisei and Hōshōryū. In July 2021 Meisei became the first Tatsunami stable wrestler to reach the
komusubi rank since
Tomonohana in 1994 and for the September 2021 tournament he became its first
sekiwake since
Kitao in 1985. In February 2024, two of the stable's wrestlers received a letter of commendation from the
Tokyo Fire Department for providing first aid to an 87-year-old man drowning after a cardiac arrest in the public baths. ==People==
