Raiden Shin'emon (雷電 震右エ門, 1842 – June 7, 1886) was a Japanese professional sumo wrestler from Hakui, Ishikawa Prefecture.

[2] He began to work at a sake shop but the owner recommended him to become a professional wrestler (rikishi).

[1] He went to Edo and was scouted by the master of Ōnomatsu stable of the time (Shokichi Matsugae), and changed his name there.

It's possible that the inheritance of Ōnomatsu's name was decided because Shin'emon was known for his negative opinion of the elders and had campaigned for a time for the abolition of this system.

However, during his time as Ōnomatsu, Shin'emon raised an apprentice, jūryō-wrestler Kabutoyama Inosuke (兜山 亥之介).

Kabutoyama assumed the shikona Ōnomatsu Wasuke II when he was still a wrestler to evoke his former master.
