Ayasegawa Sanzaemon (Japanese: 綾瀬川 山左エ門, born Tōjirō Kawamura (川村 藤次郎, Kawamura Tōjirō), October 1835 – March 8, 1877) was a Japanese sumo wrestler from Higashinari, Settsu Province (now part of Osaka in the eponymous prefecture).

Although his birthplace is generally associated with Higashinari, Settsu Province, it is sometimes mentioned that he was actually born in Nakashima, Owari.

Eventually, he left Osaka in the first year of the Bunkyū era to join the Edo-based association and was recruited into Hidenoyama stable, now being trained by the eponymous yokozuna and being stablemate with Jinmaku.

[2] In 1866, while still in makushita, he received a patronage proposal from the Himeji Domain and was given the shikona, or ring name, Aioi Matsugorō (相生 松五郎).

The conflict was eventually settled by the mediation of other wrestlers, and Takamiyama, as a reward for his loyalty to the Sakai clan, was given his historic name of "Takasago".
