JSUGE has grown and recruited new talents like Christian Thun, a German professional heavyweight boxer of 26 years old. The company also recruited Emilie Sovinco, a french boxer who aims to participate at Tokyo Olympics Games in 2020.


JSUGE believes that boxing is a vertuous sport with noble values and awesome shows. Moreover we thought that boxing is a complete sport who can benefit to the physical health and the mental health of anybody.
