Sutemi, a book co-authored by the young teacher Andrea Mazzoni in collaboration with prominent figures from the martial arts world, stands as a true innovation in the specialized publishing sector of martial arts. This marks Andrea Mazzoni's second work, focusing on the diverse and inspiring practices rooted in Minoru Mochizuki Sensei's traditional school. While his initial book covered all aspects of Nihon Tai Jitsu - Ju Jutsu as a whole, this second volume delves into the captivating realm of 'sutemi waza'-the sacrifice techniques that Roland Hernaez Sensei learned from Minoru Mochizuki Sensei and brought into the present day. Sutemi is not merely a publication filled with images and technical actions, but also an in-depth work enriched by historical research that enhances the content and is sure to captivate the reader. Andrea Mazzoni, the son of Daniele Mazzoni Sensei, the leader of Nihon Tai Jitsu in Italy, is considered one of the most promising talents in the technical martial scene in Italy. Through his dedication, passion for the study of Nihon Tai Jitsu, and openness to establishing connections with other schools, he serves as an example to future generations of martial experts. I am pleased to encourage him to continue on the Bu-Do path. Giancarlo Bagnulo ACSI Martial Arts National Coordinator 7th dan Ju Jutsu Teacher
