Umegatani Tōtarō I (梅ヶ谷 藤太郎, March 16, 1845 – May 15, 1928) was a Japanese professional sumo wrestler from the town of Haki, Chikuzen Province, now Shiwa, Fukuoka Prefecture.

From around the age of 12, he attended a temple school and began to wrestle, and by the time he was 16, he was known as "Chikuzen Muteki" (筑前無敵, 'invincible').

[2][1] After some time, he joined Minato stable and changed his ring name to Umegatani (梅ヶ谷) in honor of his hometown, Umegaya in Shiwa Village.

Umegaya, however, remained calm and stayed in the prefecture to play an active role in pacifying the conflict.

[2] Between 1876 and 1881, Umegatani started a period of dominance over Tokyo-sumo, winning 58 consecutive bouts, a streak only stopped once when he lost to fellow-ōzeki Wakashima.

In February 1884, Umegaya received a yokozuna license from both the Yoshida (Tokyo-sumo) and Gojō [ja] (Osaka-sumo) families.

The bout was against maegashira Ōdate, which ended in a draw after a heated battle that is said to have delighted the Emperor, and boosted sumo's popularity, which had declined after the Meiji Restoration.
