Tanikaze Kajinosuke was a Japanese sumo wrestler from the Edo period. Officially recognized as the fourth yokozuna, he was however effectively the first, as he was the first to be awarded the title during his lifetime. He achieved great fame and, though championships from this period are unofficial, he achieved the equivalent of 21 tournament championships. He was also the coach of Raiden Tameemon.

Sumo is a form of competitive full-contact wrestling where a rikishi (wrestler) attempts to force his opponent out of a circular ring (dohyō) or into touching the ground with any body part other than the soles of his feet.
