Ichikawa Isao Hanshi 10th Dan (1935-1996), the founder of Karatedō Dōshinkan, was a charismatic teacher, a visionary, an innovator and a beacon of traditional Karatedō.
 This book describes his journey in Karatedō, beginning with his apprenticeship under Toyama Kanken Sensei and continuing until his death in 1996, and is dedicated to the comprehensive and exceptional kata curriculum of Karatedō Dōshinkan. Furthermore, it makes a modest attempt to offer insight into the grandmaster's personality – an attempt to make the essence of his school, Karatedō Dōshinkan, tangible.
 At the age of six, Ichikawa Isao Hanshi began training at the Shūdōkan Dōjō under Toyama Kanken Sensei in Tokyo. Toyama Sensei taught hundreds of students over the decades, but Ichikawa Isao Hanshi was his uchi deshi, his master student. He was undoubtedly an exceptional talent and the one student at the Shūdōkan Dōjō to whom everything was passed on – including an incredibly vast repertoire of kata. After Toyama Sensei's death, Ichikawa Isao Hanshi left Japan and settled permanently in Austria, where in 1968 he and his brother, Ichikawa Nobuo, founded their organization, "Karatedō International Dōshinkan."
 This book is a tribute, a bow to this great master of Karatedō.
