I bought this on Amazon for the list price of 3600 yen, but I haven't read it. I've stored it in a dark place, but since it's been stored by an amateur, please refrain from purchasing if you are overly concerned about its condition. No pets, no smoking. I will put it in a waterproof vinyl bag, protect the corners with cushioning material, and send it in a cardboard envelope via Yu-Packet Post. Book Overview The author says: "Until recently, I believed that the essence of Aikido could only be understood through metaphysics, which goes beyond the limits of applying physics. However, at the age of sixty, at this very moment, I suddenly understood everything, as if struck by a bolt from the blue. And with an absolute certainty that cannot be expressed with words like '300% confidence'! If I were in ancient Greece, I might have run around shouting 'Eureka!' Yes, I can bring the true essence of the mysterious Aikido techniques, which have been positioned in the secret depths of Japanese martial arts and have long been mastered by only a few legendary masters, into the realm of scientific understanding that at least theoretical physics can provide!" #Kunio Yasue #Kunio_Yasue #book #Lifestyle/Sports Aikido Martial Arts Martial Arts Combat Sports
