立ち会い稽古

Tachiai Keiko is one of the Supplementary Sumou exercises.

Rikishi do it to sharpen their Tachiai and practice hitting in the Ice-cube Tachiai with full Power.

As an alternative to matches, when you're not fighting, practice the Tachiai, i.e. charging into your opponent, along with Butsukariki Keiko.
