Butsukari-geiko is one of sumo’s most intense training methods, where younger wrestlers crash forward with full force and senior wrestlers receive the impact. This practice builds pushing power, stamina, and mental toughness, making it an essential part of sumo culture.

The Basics of Butsukari-geiko

Butsukari-geiko is a traditional training method in sumo where junior wrestlers launch themselves with full force at their seniors, who lend their chests to receive the impact. The primary goal is to develop pushing power and stamina, which are essential in actual matches.

It is not just a contest of strength. It is also a place to acquire technique: the stance at the tachiai (initial charge), the movement of the feet, and the position of the hips are all refined naturally. This makes wrestlers stronger and more stable in real matches.


The Flow of Butsukari-geiko

Training follows a set sequence.

Through this repetition, wrestlers strengthen both their physical stamina and mental resilience.


The Purpose of Butsukari-geiko

Historical Background of Butsukari-geiko

Butsukari-geiko dates back to the Edo period and has long been regarded as the gateway to strength for junior wrestlers. The sumo philosophy of “training must be harsher than the real match” is embodied in this practice.

While matches may last only a few seconds, butsukari-geiko continues until the wrestler is exhausted. This ensures that, in real bouts, wrestlers can maintain composure and fight with confidence.
