[1] He was born Oshida Otojirō (押田 音次郎), but later changed his name to Koe Otomatsu (小江 音松).

[2] Oshida was later adopted by the 15th yokozuna Umegatani and joined his Ikazuchi stable in June 1892 at the age of 14.

His father was initially reluctant to let him join at such a young age but Umegatani Tōtarō I personally guaranteed his well-being.

Initially wrestling under the shikona name of Umenotani Otomatsu (梅ノ谷 音松), he officially took on the Umegatani Tōtarō name before his fourth tournament as an ōzeki in January 1902.

Umegatani had reached sumo's highest rank at the age of 25 years and 3 months, making him the youngest ever yokozuna at that time.

[1] He died at the age of 49 whilst still active in sumo as a judge and head of Ikazuchi stable.
