Purchased for 1800 yen + tax and unread. It has been stored in a dark place at home, so please refrain from purchasing if you are overly concerned about its condition. It will be placed in a waterproof vinyl bag, with corner protection using cushioning material, and then sent via post in a cardboard envelope. Book Overview: A scientific analysis of "battles without rules"! The undefeated military philosophy of a fighting master. Fights are not about physical strength. 90% of the outcome is determined by preparation, and preparation is done with the mind. This book introduces the know-how and practical methods for cultivating the mindset of preparing for a fight, habituating it in daily life, and achieving certain victory. It also directly relates to the development of crisis management skills, which are lacking in modern Japanese society. I am also selling many other martial arts-related books, so please take a look if you are interested. I plan to list many new items in the future, including DVDs. #Yoshimichi Hayashi #book #lifestyle/sports #MixedMartialArts #Karate #MartialArts #SelfDefense
